RESUMEN

BACKGROUND: This study aimed to explore the impacts of different middle-ear mucosal conditions on the outcomes of type I tympanoplasty. METHODS: A retrospective analysis of 164 patients with chronic otitis media was carried out. The patients were divided into 4 groups according to their mucosal condition. Preoperative hearing levels and air-bone gap (ABG) before and after surgery were compared via the Kruskal‒Wallis H test. The chi-squared test and Fisher's exact test were used to assess the postoperative complications and impact factors of functional success. RESULTS: Preoperatively, neither the air conduction nor bone conduction values differed significantly among groups with different mucosal conditions. All of the ABG closed dramatically after type I tympanoplasty (P < .05) regardless of the mucosal conditions. The functional success rates were lower when the intratympanic mucosa was moderately or severely edematous compared with mildly edematous or normal (P < .05). The disease course, perforation site, and perforation size, as well as the status of the opposite ear, were not related to the auditory functional outcome. The differences in postoperative reotorrhea and reperforation among the 4 groups were not statistically significant. CONCLUSION: Preoperative hearing levels were not affected by middle-ear mucosal conditions. The functional success rate was influenced by mucosal conditions, but hearing levels were significantly enhanced after surgical intervention regardless of the mucosal status. Postoperative complications were not related to the mucosal conditions. Thus, type I tympanoplasty is adoptable for mucosal abnormalities when pharmacotherapy cannot result in a healthy tympanum.

RESUMEN

Packing of tympanic cavity is generally considered an essential step in myringoplasty. However, each packing material comes with one or another side effect. The objective of this meta-analysis was to compare the results of Type 1 myringoplasty with or without packing. Pubmed, Cochrane database, Embase, Google Scholar, and clinicaltrials.gov were searched using 'tympanoplasty or myringoplasty and packing' as the search query. All RCTs / quasi-RCTs comparing tympanoplasty Type 1 with packing (control) versus without packing (intervention) of tympanic cavity in the human population were included. For dichotomous and continuous outcomes, relative risks (RR) and mean differences (MD) were calculated with 95% confidence interval, respectively. Heterogeneity was assessed using I2 statistics. Publication bias was checked using funnel plot and Egger's test, if applicable. Quality of evidence was assessed for each outcome using GRADE approach. Eleven studies were deemed eligible. For graft uptake and functional success rate, RR of 1.01 and 1.05 were obtained, respectively, showing no significant differences between the intervention and control groups. At 1st and 3rd postoperative month, no-packing group showed 3.86 dB and 2.08 dB better air-bone gap (ABG) closure than the packing group, respectively. Also, intervention with no-packing was 9.28-minute shorter procedure. With RR 0.35, no-packing had significantly lesser postoperative aural fullness. Type 1 tympanoplasty performed with or without packing show comparable results in terms of graft uptake and functional success rate. However, if performed without packing, it takes shorter time, provides early hearing improvement and causes less aural fullness. Key Words: Tympanoplasty Type 1, Packing, Gelfoam, No-packing, Meta-analysis, Endoscopic myringoplasty.

RESUMEN

OBJECTIVE: To determine the predictive factors for residual disease occurring after surgical removal of congenital cholesteatomas and whether these predictive factors differ between microscopic ear surgery (MES) using data from the literature and transcanal endoscopic ear surgery (TEES) using data from our own institution. METHODS: Twenty-three patients with a congenital cholesteatoma who underwent surgical treatment at Yamagata University Hospital between December 2011 and December 2017 were retrospectively investigated. We divide TEES into three different approaches: non-powered TEES, powered TEES and dual MES/TEES. Main outcome measures were Potsic stage, closed or open congenital cholesteatoma type, TEES surgical approach, appearance of residual disease, tympanoplasty type and hearing outcome. RESULTS: A logistic regression analysis was conducted on the Potsic stage, closed or open type, TEES surgical approach and age to obtain the odds ratio for residual disease. The chance of residual disease significantly increased in the presence of an open-type congenital cholesteatoma (odds ratio: 30.82; 95 % confidence interval: 1.456-652.3; p = 0.0277), but not for any of the other factors including Potsic stage. The timing of the confirmation of residual disease after ossicular chain reconstruction was analyzed using a Kaplan-Meier analysis. The residual disease rate was significantly higher with an open-type congenital cholesteatoma (log-rank test, p < 0.05). In addition, all residual disease occurred within three years after surgery. CONCLUSIONS: Our results showed that an open-type congenital cholesteatoma is the strongest predictive factor for residual disease when removing a congenital cholesteatoma by TEES.

RESUMEN

OBJECTIVE: To evaluate tympanic membrane regeneration therapy (TMRT) for pediatric tympanic membrane perforations (TMPs). STUDY DESIGN: Intervention study. SETTING: Research institute hospital. PATIENTS: In this study, 20 patients with chronic TMP (M/F: 13/7, 13/8 ears, age 0-15 years) treated with TMRT were evaluated. As comparison, 20 pediatric patients with chronic TMP who underwent myringoplasty/tympanoplasty were included. INTERVENTIONS: For the TM repair procedure, the edge of the TMP was disrupted mechanically, and gelatin sponge immersed in basic fibroblast growth factor was placed inside and outside the tympanic cavity and covered with fibrin glue. The TMP was examined 4 ± 1 weeks later. The protocol was repeated up to four times until closure was complete. MAIN OUTCOME MEASURES: Closure of the TMP and hearing improvement were evaluated at 16 weeks after the final regenerative procedure. Adverse events were monitored. RESULTS: The mean follow-up period was 427.1 days. The TM regenerated in all cases, but pinhole reperforation occurred in two cases, and the final closure rate was 90.5% (19 of 21). Hearing improved to 24.9 ± 7.6 dB on average before surgery and to 13.8 ± 5.4 dB after surgery. The AB gap improved from 12.9 ± 8.0 to 5.2 ± 3.5 dB.The myringoplasty/tympanoplasty group had significantly lower AB gap improvement compared with the TMRT group. There were no adverse events. CONCLUSIONS: TMRT can be expected to regenerate near-normal TMs with a high closure ratio, resulting in better-hearing improvement compared with the myringoplasty/tympanoplasty group, and is an effective treatment for children with long life expectancy.

RESUMEN

OBJECTIVE: The management options for small acoustic tumors are still controversial, and surgery is indicated in a select number of patients only. This is to avoid unnecessary extensive operations and risk of complications. Endoscopic transcanal approach, which was recently introduced, can be an alternative option to overcome these challenges. We have developed a modified technique for endoscopic transcanal removal of small acoustic tumors with tympanoplasty using tragal cartilage and without the need to harvest abdominal fat for obliteration. There was also no need to do an ear cul-de-sac procedure compared with the previous method. We report the long-term outcomes of this approach. STUDY DESIGN: Retrospective review. SETTING: Tertiary hospital. PATIENTS: Those who were diagnosed with small acoustic tumors between June 2016 and June 2022 were enrolled. INTERVENTIONS: Tumor removal via a Modified Endoscopic Transcanal Transpromontorial Approach (mETTA). MAIN OUTCOME MEASURE: Tumor control rate, closure rate of tympanic membrane, and complications such as cerebrospinal fluid (CSF) leakage and facial palsy were analyzed. Operation time and hospital stay were also analyzed. RESULTS: Twenty-two patients with a mean age of 55.5 ± 9.4 years were enrolled. Eighteen were vestibular schwannomas (VS), two were intracochlear schwannomas (ICS), and two were with intravestibulocochlear schwannomas (IVCS). Gross total removal was achieved in 21 cases. One had developed significant CSF leakage, and the other patient complicated with permanent facial palsy. The tympanic membrane healed well in all patients, but three patients showed delayed healing until several months and treated conservatively. Mean operation time was 149.6 ± 48.4 minutes, mean hospital stay was 8.9 ± 4.5 days, and mean postoperative follow-up period was 42.0 ± 15.7 months. CONCLUSION: Long-term results of modified endoscopic transcanal approach to small acoustic tumors are acceptable and comparable to classical treatments such as translabyrinthine approach or gamma knife radiation. This is an alternative option for smaller tumors warranting surgical removal and maintained cosmetic advantages.

RESUMEN

This study aimed to compare total endoscopic ear surgery (TEES) and microscopic postauricular canal-wall-down tympanomastoidectomy (CWD) in cholesteatoma surgery in our clinic. This study included 59 patients, of whom 30 and 29 were operated on with CWD in 2016-2018 and TEES in 2019-2021, respectively and compared regarding intraoperative findings, hearing outcomes, long-term outcomes, and recidivism rates between groups. This study excluded patients in stage IV according to the European Academy of Otology and Neurotology/Japan Otological Society Staging System on Middle Ear Cholesteatoma, aged < 18, with congenital cholesteatoma, who underwent revision surgery. Two patients in the TEES group had recidivism (6.9%), with recurrent disease observed in both patients and residual disease in none, whereas 3 patients in the CWD group had recidivism (10%), including recurrent disease in 2 and residual disease in 1 patient. Tympanic membrane perforation occurred in 2 (6.9%) and 1 (3.3%) patients in the TEES and CWD groups, respectively. The 2 groups revealed no significant difference in terms of recidivism and perforation rates (P=1.000, P = .612). The CWD group had a longer mean operation time (225.54 ± 47.86 minutes) than the TEES group (160.55 ± 24.98 minutes) (P < .001). The 2 groups demonstrated no significant difference regarding pre- and postoperative air-bone gap (ABG) and ABG gain (P = .105, P=.329, P=.82, respectively). Total endoscopic ear surgery provides similar results in terms of hearing, recidivism, and long-term outcomes with the microscopic CWD approach. However, the CWD approach is still important, especially in patients in advanced stages.

RESUMEN

A labyrinthine fistula is a severe complication of middle ear cholesteatoma that can cause profound sensorineural hearing loss and vertigo. However, there is no consensus regarding the transition to postoperative hearing. Although hearing deteriorates gradually with a delay in some cases of labyrinthine fistula, insufficient consideration has been given to this point. We examined perioperative changes in cases of middle ear cholesteatoma with labyrinthine fistulas. We retrospectively reviewed the medical records of 578 patients with middle ear cholesteatoma who underwent tympanoplasty at our hospital between 2016 and 2021. Patients with labyrinthine fistulas were selected; their perioperative bone-conduction hearing was assessed. Fistula depth was determined following the classification reported by Dornhoffer et al. The hearing was compared preoperatively, early postoperatively (3-6 months), and 1 year postoperatively. Forty-eight patients (8.3%) had labyrinthine fistulas. Regarding depth, 21 cases were type I, 14 were type IIa, 3 were type IIb, and 10 were type III. Preoperative bone-conduction hearing was significantly poor in invasion type IIb or deeper cases. Cases with type IIb or deeper fistulas, multiple fistulas, or vertigo deteriorated postoperatively. Type III cases or those with multiple fistulas deteriorated further from the early postoperative period to 1 year postoperatively. Concerning frequency, 500 and 2000 Hz showed a delayed deterioration. This is a valuable report of delayed hearing loss after surgery in patients with a labyrinthine fistula. This change is associated with the labyrinthine fistula's depth and multiple fistulas-this is important during preoperative counseling of patients undergoing surgery.

RESUMEN

OBJECTIVES: To evaluate the anatomic and functional outcomes of type1 tympanoplasty with endoscopic modified butterfly cartilage-perichondrium technique. METHODS: In our modification, perichondrium was elevated circumferentially till the attached part of the composite graft was approximately same size and shape of the perforation, cartilage was trimmed based on the perforation but 0.5 mm larger. Cartilage portion of the graft was placed medial to the edge of the perforation, then perichondrium was rolled out and draped on the circumferential raw surface of remaining tympanic membrane around. RESULTS: At 4 months postop, the anatomic integrity rate of the tympanic membrane perforation for small & medium sized perforation and large sized perforation group were 100 % and 94 % (p > 0.05). For the small & medium perforation group, the mean pre and 4 months postop ACs were 30 ± 8 dB and 18 ± 6.4 dB (p < 0.01). The mean pre and 4 months postop ABGs were 19 ± 11 dB and 9 ± 3 dB (p < 0.01). For the large perforation group, the mean pre and 4 months postop ACs were 43 ± 12.5 dB and 21.5 ± 7 dB (p < 0.01). The mean pre and 4 months postop ABGs were 34 ± 8.5 dB and 12.5 ± 6 dB (p < 0.01). The differences of mean 4 months postop ACs and mean 4 months postop ABGs between the two groups were not significant (p > 0.05). CONCLUSIONS: Compared to the conventional inlay butterfly cartilage tympanoplasty technique, large or marginal perforations can be sealed more securely by this modification.

RESUMEN

Objective:To investigate the changes in hearing threshold of the acquired primary cholesteatoma of the middle ear with different degrees of eustachian tube dysfunction after balloon eustachian tuboplasty. Methods:This retrospective study included forty cases with middle ear cholesteatoma and eustachian tube dysfunction who underwent open mastoidectomy + tympanoplasty + balloon eustachian tuboplasty were enrolled. All patients were admitted from November 2020 to April 2022. The preoperative eustachian tube score of 0-2 were defined as the lower group, and the scores of 3-5 were defined as the higher group. Pure tone audiometry was measured preoperatively and 1, 3, 6 and 12 months postoperatively. The average value of bone conduction threshold and air conduction threshold of 250-4 000 Hz were calculated, and the air-bone gap was calculated simultaneously. SPSS 25.0 was used for statistical analysis. P<0.05 was considered statistically significant. Results:In the lower group, the air conduction threshold and air-bone gap at 3 months postoperatively were significantly decreased in comparison with those preoperatively（P<0.05），as was the air-bone gap at 6 months postoperatively（P<0.05）. In the higher group, the air conduction threshold and air-bone gap were significantly decreased at 3, 6 and 12 months postoperatively（P<0.05）. Conclusion:The air conduction threshold and air-bone gap of patients with the acquired primary cholesteatoma of the middle ear and eustachian tube dysfunction were significantly decreased after eustachian tube balloon dilatation. Hearing improvement lasted longer in patients with slight eustachian tube dysfunction.

RESUMEN

Objective:To analyze the surgical efficacy and safety of tympanoplasty with and without mastoidectomy for the treatment of active simple chronic suppurative otitis media（CSOM）, and to investigate whether mastoidectomy can be avoided in tympanoplasty for active CSOM. Methods:The clinical data of 55 patients（55 ears） with active CSOM were retrospectively analyzed. Based on the development of the mastoid process and the upper tympanic chamber, patients who met the criteria for wall-up mastoidectomy were classified as group A （30 patients）, and underwent tympanoplasty combined with wall-up mastoidectomy. Patients who did not meet the criteria for wall-up mastoidectomy were classified as group B（25 cases）, and underwent tympanoplasty with the opening of the middle and upper tympanic chambers and sinus drainage after partial removal of the shield plate bone. The survival rate of tympanic membrane grafts, hearing before and after surgery, and complications such as reperforation were compared between the two groups at 3 months postoperatively. Results:The overall postoperative tympanic membrane survival rate of patients with active CSOM was 96.4%（53/55）, including 96.7% in group A; 96.0% in group B. There was no significant difference in the tympanic membrane survival rate between the two groups（P>0.05）. The postoperative mean air-bone gap（ABG） was significantly reduced in both groups compared with the preoperative period, but there was no significant difference in ABG gain between the two groups（P>0.05）. No patients experienced serious adverse conditions such as peripheral facial paralysis, cerebrospinal fluid leakage, or sensorineural deafness after surgery. Conclusion:Microscopic tympanoplasty with patency of the middle and upper tympanic chambers and tympanic sinus drainage can be used to treat active simple chronic otitis media with satisfactory tympanic membrane viability and hearing improvement efficacy. This approach reduces patient trauma, prevents complications such as skin depressions in the mastoid area due to abrasion of the mastoid bone, and shortens the waiting time before surgery.

RESUMEN

OBJECTIVES: This study aimed to establish the minimal clinically important difference (MCID) and assess the responsiveness of the Chinese version of Zurich Chronic Middle Ear Inventory (ZCMEI-21-Chn). STUDY DESIGN: Prospective multicenter study. SETTING: Four Chinese tertiary referral centers admitting patients nationwide. PATIENTS: 230 adult patients with chronic otitis media (COM) undergoing tympanoplasty. INTERVENTION: Patients were required to complete the ZCMEI-21-Chn to measure health-related quality of life both preoperatively and postoperatively. An anchor-based method was used to determine the MCID of the derivative cohort by including the Global Rating of Change Questionnaire as an anchor. The generalizability and consistency with functional outcomes of the MCID estimates were externally examined in a validation cohort using a receiver operating characteristic curve analysis. RESULTS: A total of 161 and 69 patients were included in the derivative and validation cohort. The mean preoperative and postoperative ZCMEI-21-Chn total scores were 28.4 (standard deviation [SD] 14.5) and 17.5 (SD 12.6). The mean change in ZCMEI-21-Chn score was 10.9 (SD 14.3, p < 0.001). The MCIDs of the ZCMEI-21-Chn for improvement and deterioration were estimated at 13 (SD 13.0) and -7 (SD 12.9), accordingly. For patients who have reported an improved health-related quality of life, a cutoff value of 15.6 dB HL for elevation of the air-conducted hearing threshold was noticed. However, change of clinical importance judged according to MCID and Japan Otological Society criteria disagreed with each other, notably with a Cohen's kappa ( κ ) of 0.14 ( p = 0.21) in the validation cohort. CONCLUSION: This study is the first to establish the MCID of a COM-specific questionnaire in Chinese. For the COM population undergoing surgical intervention, MCID values of 13 for improvement and -7 for deterioration are recommended. The results were externally validated to be generalizable to nationwide usage, yet distinguishable from the audiological criteria. The availability of the MCID greatly adds to the clinical utility of the ZCMEI-21-Chn by enabling a clinically meaningful interpretation of its score changes.

RESUMEN

BACKGROUND This prospective study aimed to compare outcomes and hearing improvement in 51 patients with adhesive otitis media following endoscopic and microscopic tympanoplasty. MATERIAL AND METHODS Between April 2021 and April 2022, 51 patients diagnosed with pars tensa retraction and hearing loss who underwent endoscopic and microscopic cartilage tympanoplasty were included in the study (endoscopic tympanoplasty group: 26 patients, microscopic tympanoplasty group: 25 patients). Pure-tone audiometric data (0.5, 1, 2, and 4 kHz), air-bone gap (ABG), and postoperative graft intake were compared. RESULTS Hearing gain in the ABG was significant in both groups (p<0.05). When the groups were compared for mean hearing gain in the ABG, the difference was significant (p<0.05). The postoperative ABG in the endoscopic group was significantly smaller than that in the microscopic group. When the postoperative air conduction threshold was evaluated, there was no significant difference between the 2 groups at 4 kHz, whereas a significant difference was observed in the endoscopic tympanoplasty group at 0.5, 1, and 2 kHz. Postoperative graft failure and otorrhea were not observed in any of the patients. CONCLUSIONS Pars tensa retractions and adhesive otitis media show comparable outcomes with both endoscopic and microscopic techniques. In endoscopic tympanoplasty, better visualization allows for better hearing outcomes. The endoscopic method, characterized by a wide field of view and a less invasive approach, enhances access to retraction limits.

RESUMEN

BACKGROUND: Factors related to surgical outcomes of type I tympanoplasty for tympanic membrane (TM) perforation in children are controversial. OBJECTIVES: To investigate factors related to anatomical results of type I tympanoplasty for TM perforation 1 year after surgery. MATERIAL AND METHODS: We examined 68 ears. Anatomical results were determined based on the presence or absence of re-perforation, atelectasis, and otitis media with effusion. We retrospectively analyzed factors based on age (≤8 and >8 years), cause and size of TM perforation (<50% and ≥50%), history of asthma and cleft palate, and size of mastoid air cell system in bilateral ears before tympanoplasty. Audiological prognosis was evaluated in ears with anatomical success 1 year after surgery. RESULTS: Anatomical success was achieved in 80.9% (55/68) of the ears. No significant differences were observed between these factors and anatomical results. All children with cleft palate had anatomical success. Mean pure-tone average (0.5-4 kHz) was 16.25 dB HL for ears with both TM perforations <50% and ≥50%. CONCLUSION AND SIGNIFICANCE: We observed no significant relationship between factors considered and surgical outcomes. However, audiological prognosis was favorable for anatomical success regardless of TM perforation size. Accordingly, type I tympanoplasty is considered useful for TM perforation in children.

RESUMEN

OBJECTIVE: To analyze the outcomes of exoscopic versus microscopic type 1 tympanoplasty. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care otology-neurotology practice. PATIENTS: Adult subjects with a diagnosis of tympanic membrane perforation from 2018 to 2022. INTERVENTION: Exoscopic or microscopic tympanoplasty with cartilage + perichondrium or perichondrium/fascia graft. MAIN OUTCOME MEASURES: Primary outcomes were graft success rate (1 wk, 3 wk, 3 mo, and 6 mo postoperatively) and operative time. Secondary outcomes included audiometric outcomes of postoperative air-bone gap (ABG), change in ABG, pure tone average (PTA), speech reception threshold (SRT), and word recognition score (WRS) at 6-month follow-up and complication rates of cerebrospinal fluid leak, facial nerve injury, persistent tinnitus, and persistent vertigo. RESULTS: Seventy-one patients underwent type 1 tympanoplasty by a single surgeon. Thirty-six patients underwent exoscopic tympanoplasty, and 35 patients underwent microscopic tympanoplasty. Cartilage and perichondrium were utilized in 27 subjects (75.0%) in the exoscopic group and in 25 subjects (71.4%) in the microscopic group (p = 0.7, Cramer's V = 0.04). Graft success rate was as follows (exoscope versus microscope): 100% (36/36) versus 100% (35/35) at 1 week (p = 1.0, Cramer's V = 0.0), 97.2% (35/36) versus 100% (35/35) at 3 weeks (p = 1.0, Cramer's V = 0.1), 97.2% (35/36) versus 94.3% (33/35) at 3 months (p = 1.0, Cramer's V = 0.07), and 91.7% (33/36) versus 91.4% (32/35) at 6 months (p = 0.7, Cramer's V = 0.0). Operative time was 57.7 minutes for the exoscopic group and 65.4 minutes for the microscopic group (p = 0.08, 95% CI [-16.4, 0.9], Cohen's d = 0.4). There were no serious complications. All preoperative and postoperative audiometric outcomes were comparable. CONCLUSIONS: The outcomes after exoscopic versus microscopic type 1 tympanoplasty are comparable.

RESUMEN

OBJECTIVE: To characterize the management and outcomes of observation versus surgical intervention of tympanic membrane (TM) perforations in children with Down syndrome (DS). In addition, to estimate the prevalence of TM perforations in children with DS. METHODS: Retrospective case review analysis of TM perforation rate in children with DS with history of tympanostomy tube (TT) insertion at a tertiary pediatric referral center. Patients were divided into observation or surgical intervention groups and then further evaluated for the type of intervention, the number of required procedures, and success rate of hearing improvement. Risk factors contributing to perforations were analyzed, including TT type, number of TT surgeries, and perforation size. RESULTS: The TM perforation rate in children with DS with TT history was 7.0 %. Tympanoplasty was performed in 41.5 % of perforated ears with a success rate of 53.1 %. There was no statistical difference between the surgical intervention and observation groups regarding perforation characteristics or TT number and type, but the surgical intervention cohort was older. Hearing improvement based on postoperative pure tone average (PTA) threshold was noted in the successful surgical intervention group. CONCLUSION: The rate of TM perforations in children with DS after TTs is comparable to the general population. Improved PTA thresholds were noted in the surgical success group influencing speech development. The overall lower success rate of tympanoplasty in patients with DS emphasizes the need to factor in the timing of surgical intervention based on the predicted age of Eustachian tube maturation.

RESUMEN

BACKGROUND: Inflammatory conditions such as chronic otitis media (COM) can cause irreversible impairments in the microarchitecture and functions of the incus, which subsequently leads to conductive hearing loss. OBJECTIVES: To investigate bone mineral density (BMD) of the incus body (IB) and long process (ILP) on preoperative temporal CT in COM patients with and without incudo-stapedial joint discontinuity (ISJD), and also to determine the association between BMD values and the postoperative air-bone gap (ABG) in the ISJD group. MATERIAL AND METHODS: The mean IB density (IBD)/occipital bone density (OBD) and ILP density (ILPD)/OBD values were compared between the patients with and without ISJD. The correlation between ABG gain and preoperative incus density values was assessed in the ISJD group. RESULTS: The mean IBD/OBD and ILPD/OBD values were significantly higher in patients with intact ISJ. There was a moderate positive correlation between postoperative ABG gain and ILPD/OBD values in the ISJD group. CONCLUSION AND SIGNIFICANCE: The decrease in BMD of the incus may involve ILP as well as IB in patients with ISJD caused by ILP lysis in COM. A higher preoperative ILPD/OBD was correlated with a higher postoperative ABG gain in COM patients with ISJD.

RESUMEN

This review presents a comprehensive history of Artificial Intelligence (AI) in the context of the revolutionary application of machine learning (ML) to medical research and clinical utilization, particularly for the benefit of researchers interested in the application of ML in otology. To this end, we discuss the key components of ML-input, output, and algorithms. In particular, some representation algorithms commonly used in medical research are discussed. Subsequently, we review ML applications in otology research, including diagnosis, influential identification, and surgical outcome prediction. In the context of surgical outcome prediction, specific surgical treatments, including cochlear implantation, active middle ear implantation, tympanoplasty, and vestibular schwannoma resection, are considered. Finally, we highlight the obstacles and challenges that need to be overcome in future research.

RESUMEN

PURPOSE: The definitive treatment for chronic suppurative otitis media is surgery. Surgical technique and procedure varies according to individual case findings and pathology and may require mastoidectomies in which the canal wall is preserved or lowered to eradicate disease from mastoid air cells. Surgical treatment of chronic middle ear disease carries a risk of damage to the inner ear. The aim of this study was to investigate whether the noise produced by the tour system following chronic ear surgery causes sensorineural hearing loss, a condition for which not many studies have been published in the literature. METHODS: The study consisted of a total of 49 patients with type I, type II and type III canal wall preservation and 62 patients with tympanoplasty with canal wall preservation and lowering. Bone and air thresholds were compared before and after middle ear surgery. Changes in bone and air thresholds were compared according to the type of tympanoplasty. RESULTS: In the ICW-I, ICW-II and ICW-III tympanoplasties, and in the ICW and CWD tympanoplasties, the preoperative and postoperative values of the opposite ear hearing measurements were performed, and did not differ according to the type of surgery. There is no correlation drilling duration and hearing for the opposite ear. CONCLUSION: The prevention of postoperative sensorineural hearing loss depends on multiple factors, and assessing the magnitude of hearing loss in relation to these factors is important in determining the success of the surgery.

RESUMEN

Objective:To study the difference of postoperative efficacy between two-person three-hand ear endoscopy and microscopic tympanoplasty in patients with chronic suppurative otitis media, and to explore the advantages and disadvantages of two-person three-hand ear endoscopy. Methods:A retrospective study was conducted on 100 patients who underwent tympanoplasty in the Department of Otolaryngology and Head and Neck Surgery of Hunan People's Hospital from April 2019 to March 2023, and they were divided into 2 groups with 50 cases each according to random number table method. Among them, 50 cases underwent endoscopic tympanoplasty in two-person three-hand（group A） and 50 cases underwent routine microscopic tympanoplasty（group B）. The operation and postoperative conditions of the two groups were followed up. Results:In group A, the mean operation time was（65.78±18.21） min, the mean intraoperative blood loss was（12.94±4.46） mL, the postoperative pain score was（1.82±0.60） points, and the mean postoperative hospital stay was（2.76±0.72） d. The mean operation time of group B was（89.45±20.38） min, the mean intraoperative blood loss was（22.78±5.74） mL, the postoperative pain score was（2.98±0.85） points, and the mean postoperative hospital stay was（3.82±0.75） d, which with statistical significance between the two groups（P<0.05）. Hearing in both groups was significantly improved 6 months after surgery, and the difference was statistically significant before and after surgery（P<0.05）, but there was no significant difference between the two groups before surgery and 6 months after surgery（P>0.05）. There were 2 cases in group A（4%） and 1 case in group B（2%） complicated with tympanic cord injury during operation, and the difference was not statistically significant（P>0.05）. There were 47 cases of A group（94%） of one-time healing of tympanic membrane after operation, 48 cases（96%） of group B, and the difference was not statistically significant（P>0.05）. Conclusion:There is no significant difference in cure rate and hearing improvement between two-person three-hand ear endoscopic tympanoplasty and conventional microscope surgery, and the operation time is significantly shortened, the amount of blood loss is less, and the postoperative recovery is faster. It has the advantages of clear operating field, two-person three-hand operation, minimally invasive, and can reach the range of middle ear tympanic sinus and mastoid apex, and the surgical complications are seldom, which is worth promoting.

RESUMEN

A cholesteatoma is an expansion of keratinizing squamous epithelium that enters the middle ear cleft from the outer layer of the tympanic membrane or ear canal. Choleatomas are always treated surgically. Recurrence of the illness presents another challenge for the patient and the surgeon, though. There have been reports of recurrence rates as high as 30% in adults and as high as 70% in children. Here, we describe a case of persistent recurrent otorrhea following revision surgery, along with acquired recurrent cholesteatoma following canal wall down surgery. A 38-year -male with underlying Diabetes Mellitus and Hypertension presented with left scanty and foul-smelling ear discharge for 2 years and left reduced hearing. He was diagnosed with left chronic active otitis media with cholesteatoma for which he underwent left modified radical mastoidectomy, meatoplasty and tympanoplasty in 2017. Five months post operatively, he presented with left otorrhea. However, he defaulted followed up and presented in April 2018 for similar complaints. Otoscopy examination revealed left tympanic membrane perforation at poster superior quadrant of pars tensa and bluish discoloration behind pars flacida. He was diagnosed as recurrent left cholesteatoma and subsequently he underwent left mastoid exploration under general anesthesia in June 2018. Postsurgery, he developed recurrent ear discharge which was treated with topical antibiotics and ear toileting. We report a case of recurrent Cholesteatoma despite canal wall down procedure requiring a second redo procedure and with persistent recurrent otorrhea after the redo procedure.However, this case demonstrates the need for regular follow ups even after a canal wall down procedure for detecting recurrence of disease. Moreover, this case denotes some of the patient factors and surgeon factors involved in disease recurrence. Furthermore, importance of opting for an imaging study in case of high suspicion of the disease.
