RESUMEN
OBJECTIVE: To analyze the outcomes of exoscopic versus microscopic ossicular chain reconstruction (OCR). STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care otology-neurotology practice. PATIENTS: Adult subjects with a diagnosis of ossicular discontinuity from 2018 to 2022. INTERVENTIONS: Exoscopic or microscopic primary OCR (without mastoidectomy) with a partial ossicular replacement prosthesis (PORP) or total ossicular replacement prosthesis (TORP). MAIN OUTCOME MEASURES: Audiometric outcomes at 3 months and 1 year postoperatively including bone and air pure tone averages (PTA), air-bone gap (ABG), change in ABG, speech reception threshold (SRT), and word recognition score (WRS). Secondary outcomes included operative time and complication rates of primary and delayed graft failure, tympanic membrane lateralization, prosthesis extrusion, cerebrospinal fluid leak, facial nerve injury, profound hearing loss, persistent tinnitus, and persistent vertigo. RESULTS: Sixty ears underwent primary OCR and were subdivided based on prosthesis type (PORP and TORP) and surgical approach (exoscope vs microscope). Exoscopic OCR was performed on 30 ears (21 PORP, 9 TORP), and microscopic OCR was performed on 30 ears (19 PORP, 11 TORP). In the overall group (PORP + TORP) and in the PORP and TORP subgroups, there were no significant differences in 1) demographics, 2) intraoperative findings, and 3) audiometric outcomes of bone and air PTA, ABG, change in ABG, SRT, and WRS at 1 year postoperatively. Operative time was 64.7 and 59.6 minutes for the exoscopic and microscopic group, respectively (p = 0.4, 95% CI [-16.4, 6.1], Cohen's D = 0.2). CONCLUSIONS: Audiometric and surgical outcomes after exoscopic and microscopic OCR are comparable.
RESUMEN
STUDY DESIGN: Review of database. SETTING: Tertiary care neurotology center. PATIENTS: Patients undergoing adverse events. INTERVENTION: MAUDE database evaluation of Eustachian tube balloon dilation (ETBD) for the treatment of Eustachian tube dysfunction. MAIN OUTCOME MEASURES: Medical device reports (MDRs) from the MAUDE database were analyzed for adverse patient events (AE) and device malfunctions (DM) among different devices for ETBD. The objective of this analysis is to assess AE rates and compare them across different devices. Sales data was also used to calculate AE rates. RESULTS: There were 18 MDRs noted in the MAUDE database for patients undergoing ETBD out of an initial 23 results. When separated into devices, the Aera had 9 total MDRs (50 %), Xpress had 8 (44.4 %) and Audion had 1 (5.6 %). There were 10 AE and 8 DM. When separated by device, Aera had 4 AEs and 5 DMs, Xpress had 5 AEs and 3 DMs, and Audion had 1 AE. The most common AE was subcutaneous emphysema (n = 4), in the head and neck region with one report of mediastinal involvement. Using this sales data, the Aera balloon has an MDR rate of 0.0128 % is established, with a rate of AE at 0.0058 %. The Audion balloon had an MDR and AE rate of 0.0164 %. CONCLUSIONS: ETBD is a safe procedure with minimal complications, with subcutaneous emphysema being the most commonly reported adverse event, consistent with literature findings. A comprehensive analysis of AE, coupled with sales data, indicates a commendably low MDR rate of 0.0128 % for the Aera balloon while the Audion balloon had an MDR rate of 0.0164 %. These findings offer valuable insights on post-procedure expectations and engaging in informed consent discussions with patients, highlighting the overall safety of ETBD as an intervention.
RESUMEN
Smoking prevalence remains high in Europe and widening socioeconomic group differences are driving health inequalities. While plain packaging policies disrupt tobacco industry tactics that sustain smoking, evidence of their equity impact is sparse. This study evaluated the implementation of plain packaging in Ireland in 2018 on consumer responses, overall and by the socioeconomic group. Consecutive nationally representative cross-sectional surveys (2018, n = 7701 and 2019, n = 7382) measured changes in 13 consumer responses among respondents who smoked across three domains: product appeal, health warnings effectiveness, and perceived harmfulness of smoking. Multiple logistic regression-derived adjusted odds ratios with 95% confidence intervals to compare responses post- versus pre-implementation adjusting for age, gender, educational level, and heaviness of smoking. A stratified analysis examined changes by socioeconomic group indexed using educational level. There were statistically significant changes in consumer responses to plain packaging policy implementation across 7/13 outcomes studied. Five changes were aligned with expected policy impacts (2/6 product appeal outcomes and 3/4 health warning effectiveness outcomes). Two responses were also observed which were not expected policy impacts (1 appeal-related and 1 perceived harm-related outcome). There was no change in five outcomes. Differences in consumer responses between educational groups were generally small, mixed in nature, and indistinguishable when interval estimates of effect were compared. Implementation of plain packaging in Ireland had intended impacts on consumer responses. Including plain packaging requirements in revising the European Union's legislative frameworks for tobacco control will help build progress towards a Tobacco-Free Europe without exacerbating smoking inequalities.
RESUMEN
OBJECTIVE: Identify if pre-incident aspirin influences severity and outcome of idiopathic sudden sensorineural hearing loss (SSNHL). STUDY DESIGN: Retrospective review. SETTING: Tertiary care center. METHODS: Patients with idiopathic SSNHL were identified and separated into aspirin and non-aspirin groups. Variables, including demographics, comorbid conditions, audiologic outcomes were identified and compared between groups. RESULTS: One hundred forty-eight patients were included that met inclusion criteria. There were 38 patients who were on pre-incident aspirin therapy and 110 patients not on aspirin prior to the onset of SSNHL. Pre- and post-treatment audiologic status was worsened in the aspirin group. Other comorbid conditions, including hyperlipidemia, coronary artery disease (CAD), cerebrovascular accident (CVA), and vertigo symptoms had an effect as well. With multivariate analysis, CAD, CVA, and vertigo symptoms appeared to have an effect more than aspirin. CONCLUSIONS: Patients on aspirin have a worsened pre- and post-treatment audiologic status. This appears to be more due to the underlying CAD or history of CVA rather than aspirin use itself.

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.

The COVID-19 pandemic highlighted the importance of strengthening health protection worldwide. To address this as a public health priority in Ireland, between December 2021 and October 2022 the first national Health Protection Strategy (2022-2027) for the Irish Health Service Executive (HSE) was developed. We describe the approach taken to develop a first national health protection strategy for Ireland, and highlight the key lessons learned. Key steps in strategy formation included detailed stakeholder analysis, exploration of the context for the strategy and development of a comprehensive consultation plan. Two stakeholder consultation workshops were held. The first focused on defining strategic vision, aim and objectives, the second verified objectives and identified enablers. A subsequent e-consultation invited feedback from wider stakeholders. The published strategy outlines 10 strategic objectives and 11 enablers. Key lessons identified from the strategy development process include the importance of clear leadership and oversight, the value of identifying the context for change, ensuring adequate consultation planning, taking a multidisciplinary approach with strong stakeholder engagement and the need to maintain a strategic perspective. Lessons from our experience can support colleagues internationally to strategically set out their priorities for health protection beyond COVID-19.

Aortoiliac occlusive disease (AIOD) can occur from either chronic, progressive atherosclerotic disease, acute on chronic thrombosis or acute arterial embolism, and can all result in limb ischemia. Bypass surgery had long been the gold standard for treatment for AIOD, however, with advances in endovascular techniques, minimally invasive treatment of aortoiliac lesions has become the first line choice of management in many cases. Herein, we describe a case of utilizing the Inari ClotTriever to perform aortoiliac mechanical thrombectomy and the ARTIX thrombectomy system to perform an embolectomy the superficial femoral artery, highlighting new therapies to treat AIOD.

OBJECTIVES: Evaluate the effect of rurality on newborn hearing screen outcomes in Michigan. METHODS: Patients in the Michigan Department of Health and Human Services (MDHHS) Newborn Hearing Screening database that failed or did not receive their initial screen from 2015 to 2020 were evaluated. Using the U.S. Department of Agriculture Rural-Urban Continuum Codes (RUCC), patients were assigned a 1-9 code based on the population of their zip code, with 1 being the most urban and 9 being the most rural and outcomes between these patients were compared. RESULTS: There were 34,928 patients initially identified. Patients that had follow-up testing after a failed NBHS had a slightly higher RUCC than those that did not follow-up, 2.3 versus 2.2, respectively (p < 0.001). There was a significant difference between those that refused screening, with a mean RUCC of 4.2, and those that had a failed initial screen having a mean RUCC of 2.1 (p < 0.001). Similarly, those with equipment failure had a higher mean RUCC, 2.8, compared to those that had screening completed (p < 0.001). CONCLUSIONS: More rural areas are more likely to refuse a newborn hearing screen as well as have equipment failure options. There was no difference in rurality scores of those that had a follow-up screen after a failure and those that did not. LEVEL OF EVIDENCE: IV Laryngoscope, 134:2937-2940, 2024.

OBJECTIVE: Evaluate the safety and efficacy of exoscope-assisted stapedotomy. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care neurotology clinic. PATIENTS: Adult patients with otosclerosis undergoing stapedotomy. INTERVENTIONS: Primary stapedotomy. MAIN OUTCOME MEASURES: Evaluation of audiologic outcomes, including pure-tone average, bone-conduction thresholds, word recognition score, and air-bone gap. Complications, need for scutum removal, and length of surgery were also evaluated. RESULTS: A total of 47 patients were identified, and 24 patients underwent surgery with the microscope and 22 with the exoscope. There were significant improvements in pure-tone average, mean bone-conduction thresholds, and air-bone gap for both groups. There was no difference in preoperative or postoperative audiologic status for either group. There was no difference in rates of dysgeusia, chorda tympani nerve damage, dizziness, or facial paresis in either group. CONCLUSIONS: This study indicates similar audiologic outcomes, complication profiles, and visualization when comparing exoscopic and microscopic stapedotomy. Demonstrated here, exoscopic stapedotomy can be safely performed in a transcanal manner.

OBJECTIVE: Approximately 50 million US adults experience chronic tinnitus, yet search behaviors and topics of concern to these patients have not been investigated on a national level. STUDY DESIGN: Observational. SETTING: Online database and tertiary otology clinic. PATIENTS: Nationwide and institutional samples. INTERVENTIONS: None. MAIN OUTCOME MEASURE: A search engine optimization tool was utilized to extract metadata on "People Also Ask" (PAA) questions pertaining to tinnitus. Website quality was assessed using JAMA benchmark criteria. Search volume trends were investigated along with institutional-level data on tinnitus incidence. RESULTS: Of the 500 PAA questions assessed, the majority (54.0%) contained value-type content. The most popular question categories pertained to tinnitus treatment (29.3%), alternative treatment approaches (21.5%), technical details (16.9%), and timeline of symptoms (13.4%). Patients were most interested in treatment with wearable masking devices and most commonly searched for tinnitus as being attributable to a neurologic etiology. Online searches pertaining to unilateral tinnitus symptoms have increased >3-fold since the onset of the COVID-19 pandemic. Likewise, review of patient encounters at our tertiary otology clinic revealed a nearly 2-fold increase in tinnitus consultations since 2020. CONCLUSIONS: Topics of interest and concern identified herein may inform the development of patient education materials and help guide clinical practice. Online search data suggest an increase in tinnitus searches since the onset of COVID-19, which did correlate clinically with an increase in tinnitus consultations at our institution.

OBJECTIVE: To evaluate if endolymphatic sac decompression (ESD) significantly improves secondary symptoms of Meniere's disease including tinnitus and aural fullness. STUDY DESIGN: Survey study with retrospective chart review. SETTING: Tertiary care center. METHODS: Survey of adult patients with Meniere's disease that underwent primary ESD surgery from 2015 to 2020. Subjective reporting of pre- and postoperative aural fullness and tinnitus based on postoperative survey. Survey results and audiologic data of the patients that reported were compared pre- and postoperatively. RESULTS: Statistical analysis was performed using weighted kappa statistics to examine the level of agreement. There was a value of 0.12 for pre- and postoperative aural fullness, indicating a difference in the two groups with 77 % having improvement and only 4 % having worsening. There was a value of 0.21 for pre- and postoperative tinnitus, demonstrating a lack of agreement with 58 % having improvement and 4 % having worsening. Overall, there was significant improvement in both tinnitus and aural fullness postoperatively. There was no significant difference in word recognition score, speech reception threshold, or pure tone average between the pre- and postoperative group based on paired t-test. CONCLUSIONS: There is a significant improvement in both aural fullness and tinnitus for patients undergoing ESD with no negative effect on audiologic status. ESD is a viable option for treatment of Meniere's disease with vertigo, aural fullness, and tinnitus relief. Future prospective studies are needed to further improve the evidence of ESD's effect on secondary symptoms of Meniere's disease.

OBJECTIVE: To identify which patients with advanced otosclerosis may have the greatest audiologic improvement with stapedotomy based on different classifications of advanced otosclerosis. STUDY DESIGN: Retrospective chart review. SETTING: Single tertiary neurotology center. METHODS: Patients were divided into different classifications of advanced otosclerosis based on either a bone conduction threshold of greater than 60 dB HL (Bone Conduction (BC) Group), a word recognition score of less than 70% (Word Recognition (WRS) Group), or pure tone average of greater than 85 dB HL (Pure Tone Average (PTA) Group). Audiologic outcomes and complication profiles were compared between these groups. RESULTS: Nineteen patients met criteria for one or more group. There were 18 patients in the PTA group, 11 in the BC group, and 12 in the WRS group. There was no significant difference in the pre- or postoperative audiologic status between the different groups. CONCLUSIONS: Patients with advanced otosclerosis have significant improvements in pure tone averages and air-bone gaps following stapedotomy regardless of the classification criteria used. Stapedotomy remains a reasonable primary intervention for the majority of patients with advanced otosclerosis.

We report seven cases from our clinic with transcobalamin receptor deficiency (TCRD). None of our cases have experienced health issues or metabolic decompensation. All have experienced typical growth and development throughout childhood, with our oldest case now 10 years old. Every case has had normalization of initial biochemical abnormalities following parenteral hydroxocobalamin administration. Several cases had trace elevations of methylmalonic acid throughout childhood, all which normalized without further hydroxocobalamin administration. Population data from our state's newborn screening program suggest the incidence of TCRD is comparable to other metabolic disorders associated with elevations of C3 acylcarnitine including propionic academia, isolated methylmalonic academia and combined methylmalonic academia and hyperhomocysteinemia due to cobalamin metabolism disorders. Based on the generally benign nature of this condition, we assert that TCRD may be considered an incidental finding on newborn screen. However, additional long-term data are needed to ascertain the long term outcomes of children identified with TCRD.

OBJECTIVE: To evaluate the audiologic outcomes of microdrill fenestration for obliterative otosclerosis compared to traditional stapedotomy technique. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary referral center. PATIENTS: Adult patients undergoing stapedotomy for otosclerosis. MAIN OUTCOME MEASURES: Patients were separated into groups that underwent either microdrill or laser fenestration based on intraoperative severity of disease. Audiologic outcomes and complications were compared between the two groups. RESULTS: There were 588 ears in 519 patients that were evaluated. There was a significant postoperative improvement in pure tone average, air-bone gap, and mean bone conduction thresholds for both the obliterative and nonobliterative group (pâ<â0.001). There was no significant difference in the pre- or postoperative hearing status between the two groups. There was no significant difference in complications between the two groups, including no cases of postoperative profound hearing loss in the drill fenestration group. CONCLUSIONS: Audiologic outcomes are similar between microdrill fenestration and laser fenestration for otosclerosis. Pure tone average, air-bone gap, and mean bone conduction thresholds all improved postoperatively and were similar between groups.

BACKGROUND: Prognostic cytological and molecular features of uveal melanoma have been well researched and are essential in management. Samples can be obtained in vivo through fine needle aspirate biopsy, vitrector cutter, forceps or post-enucleation for off-site testing. This study aims to examine cytological and chromosome microarray yields of these samples. METHODS: A retrospective cohort analysis of 119 uveal melanoma biopsies submitted to our laboratory. Samples included those taken in vivo (n = 57) and post-enucleation (n = 62). Patient and tumour features were collected including age, sex, primary tumour location, basal diameter and tumour height. Prognostic outcomes measured include cell morphology, chromosomal status and immunohistochemistry. RESULTS: Post-enucleation biopsies accounted for just over half of our samples (52%). Post-enucleation samples had a more successful genetic yield than in vivo biopsies (77% vs. 50%, p = 0.04) though there was no difference for cytological yields. There was no difference in cytological or microarray yields between instruments. The vitrector biopsy group had the smallest tumour thickness (5 mm vs. 10 mm [fine-needle aspirate biopsy], p = 0.003). There was a strong correlation between monosomy 3, BAP1 aberrancy and epithelioid cell type in post-enucleation samples (Tb = 0.742, p = 0.005). However, epithelioid morphology was not associated with either monosomy 3 (p = 0.07) or BAP1 aberrancy (p = 0.24) for in vivo biopsies. CONCLUSIONS: All three biopsy instruments provide similar cytological yields as post-enucleation sampling, although post-enucleation samples had a more successful chromosome microarray yield. Epithelioid cytomorphology alone is insufficient for prognostication in in vivo biopsies, immunohistochemistry would be a useful surrogate test.

OBJECTIVES: Venous thromboembolism (VTE) is a major cause of morbidity and mortality for surgical patients. This article aims to determine factors that may have contributed to the development of VTE in patients undergoing lateral skull base surgery, to assess the validity of the Caprini Risk Assessment Model (RAM) score in this subset of patients, and to determine the efficacy of mechanical DVT prophylaxis alone in preventing VTE. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review was conducted of patients who underwent skull base surgery for vestibular schwannoma, and the rate of VTE was assessed. Patient demographics, comorbidities, and treatment factors were examined to determine risk factors associated with the development of a postoperative thrombotic event. Caprini RAM scores were compared for patients who developed a VTE. RESULTS: Among 197 patients, the rate of VTE formation was 3.5%. No individual risk factor independently contributed to the development of a thrombotic event. The mean Caprini RAM score was 4.06 in patients who did not develop a VTE and 5.14 in the patients that did develop a VTE (P = .005). The Caprini score was significant for the risk of VTE formation, with an odds ratio of 2.8 (P = .009, 95% CI = 1.3-6.2). CONCLUSION: Venous thromboembolism rates are relatively low following lateral skull base surgery. While there is no individual risk factor associated with increased VTE risk, the Caprini RAM score appears to be a useful predictor of risk. The Caprini score may be useful in identifying high-risk patients who may benefit from chemoprophylaxis for VTE prevention. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:662-667, 2022.

OBJECTIVE: To examine the role of intensive care unit (ICU) management following lateral skull base surgery for vestibular schwannoma and identify risk factors for complications warranting admission to the ICU. STUDY DESIGN: Retrospective review. SETTING: Tertiary referral center. PATIENTS: Two hundred consecutive patients undergoing lateral skull base surgery for vestibular schwannomas. INTERVENTION: Lateral skull base approach for resection of vestibular schwannoma and postoperative monitoring. MAIN OUTCOME MEASURES: Patients were grouped if they sustained an ICU complication, a non-ICU complication, or no complication. Analysis was performed to determine patient or treatment factors that may be associated with ICU complications. Multivariate and three-way analysis of variance compared groups, and multivariate logistic regression determined adjusted odds ratios (aOR) for analyzed factors. RESULTS: Seventeen of 200 patients sustained ICU complications (8.5%), most commonly hypertensive urgency (nâ=â15). Forty-six (23%) sustained non-ICU complications, and 137 (68.5%) had no complications. When controlling for age, sex, obesity, and other comorbidities, only hypertension (aOR 5.43, 95% confidence interval (CI) 1.35-21.73, pâ=â0.017) and tumor volume (aOR 3.29, 95% CI 1.09-9.96, pâ=â0.035) were independently associated with increased risk of ICU complications. CONCLUSIONS: The necessity of intensive care following lateral skull base surgery is rare, with the primary ICU complication being hypertensive urgency. Preoperative hypertension and large tumor volume (>4500âmm3) were independently associated with increased risk for ICU complications. These findings may allow for risk stratification of patients appropriate for admission to stepdown units following resection of vestibular schwannomas. Further prospective, multi-center, randomized studies are necessary to validate these findings before systematic changes to current postoperative care practices.
