RESUMEN

Background: Endoscopic sinus surgery (ESS) has become the gold standard for treating patients with chronic rhinosinusitis (CRS) refractory to medical therapy. It is considered a relatively safe and effective procedure in all age groups, with overall success rates ranging from 76% to 97.5%. However, failure of primary endoscopic sinus surgery (PESS) occurs at a rate ranging from 2% to 24%. Patients who are still symptomatic after PESS and optimal medical therapy are candidates for revision endoscopic sinus surgery (RESS). Objectives: to study the outcomes of ESS and assess the risk factors of recurrence of nasal polyps, as well as to compare the outcomes of PESS and RESS at a tertiary care teaching hospital. Design: A retrospective cross-sectional study. Methods: This study is conducted on patients with CRS with nasal polyps (CRSwNP) who underwent ESS at King Saud University Medical City (KSUMC) between May 2015 and December 2021. During this period, ESS was performed 470 times for CRSwNP. The Sinonasal Outcome Test 22 (SNOT-22) questionnaire, the Lund-Kennedy (LK) score, the Lund-MacKay (LM) score, and the polyp grading system were used to evaluate subjective and objective outcomes. They were scored preoperatively and from 6 to 12 months postoperatively. Results: Out of the 470 endoscopic sinus surgeries, 321 (68.3%) were PESS and 149 (31.7%) were RESS. Asthma, aspirin sensitivity, and Samter's triad were observed more in the RESS group. The LK and LM scores were significantly different between primary and revision sinus surgeries, revealing that PESS patients had better postoperative LK and LM scores. The RESS patients had significantly worse postoperative SNOT-22 scores compared to PESS patients. Conclusion: Lund-MacKay, Lund-Kennedy, and SNOT-22 scores improved after ESS for both primary and revision ESS patients, with better outcomes observed after PESS compared to RESS. The presence of asthma, aspirin sensitivity, Samter's Triad, high-grade nasal polyps, and older age were identified as risk factors for CRSwNP recurrence, which may require RESS.

RESUMEN

Background: Chronic Rhinosinusitis (CRS) is a common condition causing a significant worldwide burden, affecting 5%-12% of the general population. CRS is classified into type 2 and non-type 2 disease based on endotype dominance. Type 2 inflammation is distinguished by the presence of IL-4, IL-5, and IL-13 cytokines, along with eosinophil and mast cell activation and recruitment. Evidence of type 2 inflammation is ascertained by tissue eosinophil count >10/high-power field (HPF) or serum eosinophil >250 cells/mcL or total immunoglobulin E (IgE) > 100 IU/ml. Objectives: To investigate the prevalence and characteristics of type 2 inflammation in patients who presented with nasal polyps and underwent Endoscopic Sinus Surgery (ESS) in Saudi Arabia. Design: A retrospective cross-sectional Study. Methods: This study was conducted among patients who presented with nasal polyps and underwent ESS at King Saud University Medical City (KSUMC) from 2015 to 2020. Patients with nasal/sinus diseases other than Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) were excluded. Demographic data, olfaction status, and co-morbidities were collected, and radiological images were evaluated. Type 2-CRS was determined by meeting at least one of three predictor criteria (blood eosinophils ≥250 cells/mcL, tissue eosinophils ≥10/HPF, or total IgE levels ≥100 IU/ml). Blood parameters and histopathologic analysis were obtained for each patient. Results: Of the 381 patients included in the study, the prevalence of type 2-CRS, based on the EPOS2020 criteria, was 99.7% in our population. Among these patients, 47.5% had hyposmia, 38.8% had anosmia, and 13.6% had normal olfaction. The most prevalent co-morbidity was allergic rhinitis, followed by bronchial asthma. Conclusion: This study aimed to determine the prevalence of type 2 inflammation among patients Diagnosed with CRSwNP and underwent ESS in Saudi Arabia. The results showed a prevalence of 99.7%, indicating that almost all recorded patients with CRSwNP in our population had type 2 inflammation.

RESUMEN

Introduction: Inferior meatal antrostomy (IMA) is a safe and easy approach to the maxillary sinus. However, studies have shown disadvantages of conventional IMA, such as disruption of mucociliary transport and injury of the nasolacrimal duct (NLD). Endoscopic middle meatal antrostomy (MMA) has become the standard of care for addressing various maxillary pathologies. It is more functional and physiological but offers limited exposure to certain areas of the maxillary sinus, such as the prelacrimal recess, alveolar recess, and zygomatic recess. We proposed submucosal temporary inferior maxillary antrostomy (STIMA) to improve visualization and accessibility to such difficult-to-access locations. Objectives: To describe our proposed modification, to compare the degree of visualization and ease of accessibility between MMA and STIMA. Methods: This is a descriptive cadaveric study. It was performed on 4 fresh frozen human cadavers, and 8 maxillary sinuses were used to achieve the study's objectives. Different angled rigid nasal endoscopes and suction tubes were used to score the degree of visualization and ease of accessibility between the MMA and STIMA. Result: We demonstrated the superiority of the STIMA over the MMA in the degree of visualization and ease of accessibility in these difficult-to-access locations (P-value was significant, <.05). We did not encounter orbital injury or injury to the NLD in our specimens. Conclusion: STIMA is a relatively easy and safe modification of conventional IMA. It improves the degree of visualization and ease of accessibility to difficult-to-access maxillary sinus locations without the potential complications of conventional IMA.

RESUMEN

The management of chronic rhinosinusitis with nasal polyps (CRSwNP) is challenging due to disease recurrence and adverse effects. Both surgical and medical treatment modalities impact the quality of patients' lives. Monoclonal antibody treatment has recently been used successfully in CRS with limited reported adverse events. We aimed to review the literature to shed more light on the safety and adverse events associated with the biological therapy of CRSwNP. A comprehensive systematic review was conducted on the safety of different biological treatments when used for managing CRSwNP. We have included 13 studies in the present systematic review, including 12 randomized controlled trials (RCTs) and one cross-sectional study. The total sample size for the included studies was 2282 patients. Six studies investigated the safety and adverse events of dupilumab; three investigated omalizumab, three investigated mepolizumab, and only one investigated reslizumab. Some studies have reported that adverse events were common with these types of drugs. However they were not specific and self-limited. Headaches, injection site reactions, and pharyngitis were the most common adverse events found among the reported adverse events. The Dupilumab trial reported pharyngitis in 225 patients (22.4 %) followed by erythema in 9.4 %, headache in 8.1 %, epistaxis in 5.1 %, and asthma in 1.7 % of patients. Trials which used omalizumab reported headaches, nasal pharyngitis, injection-site reactions to be the most common adverse events with estimated prevalence rates of 8.1 %, 5.9 %, and 5.2 %, respectively. Mepolizumab and reslizumab studies reported that 40 % of patients were complicated by nasal polyps/congestion/pharyngitis/infections, 14 had a headache (15.5 %), two developed asthma (2.2 %), and only one patient (1.1 %) had epistaxis as an adverse event. Although the literature's current investigations indicate the safety of the biologic treatment modalities, further studies are needed as some uncertainty among the trials have been reported.

RESUMEN

Background Accurate preoperative radiological localization of parathyroid pathologies paves the way to enable less invasive surgical procedures. Results on the accuracy of the different diagnostic measures are conflicting. Also, little is known about the most common location of parathyroid lesions. This paper aims to determine the most common location of parathyroid adenoma and evaluate the diagnostic performance of radiological modalities such as ultrasonography, sestamibi scintigraphy/single-photon emission computerized tomography (SPECT), magnetic resonance imaging (MRI), and computed tomography (CT) scan for the preoperative localization of parathyroid pathologies. Methods This is a retrospective study. Data were collected from patients who underwent total or partial parathyroidectomy at King Abdulaziz University Hospital between January 2000 and March 2020. The parathyroid adenoma site was detected preoperatively by a radiological method and confirmed postoperatively by the histopathology report. The performance of each preoperative localizing radiological method was evaluated based on the accuracy in localizing parathyroid pathology. Results A total of 73 patients were included in the analysis, with females being the most common gender in the study at 64%. Only complete data files were included and incomplete data files were excluded. The most frequent mode of detecting parathyroid adenoma was a sestamibi/SPECT scan (62.5%) followed by a CT scan (50%), ultrasound (34.6%), and MRI (25%). The most common location of a parathyroid adenoma was the left side. Conclusion Sestamibi/SPECT is a frequent radiological method for detecting the parathyroid lesion site as compared with CT, MRI, and ultrasonography.

RESUMEN

INTRODUCTION: Renal cell carcinoma is known to cause metastasis to unusual sites, but metastasis to the thyroid gland is a rare occurrence, not only that, but 20 years after complete recovery is almost nonexistent. CASE PRESENTATION: We are presenting here a case of 79-year-old female who presented to us for asymptomatic progressive thyroid nodule. She had history of right nephrectomy for renal cell carcinoma 20 years ago. Ultrasound guided fine needle aspiration biopsy (FNAB) of the thyroid was non-diagnostic. Total thyroidectomy of the patient was performed, and histopathological evaluation of the specimen revealed the swelling to be of metastatic in nature secondary to renal cell carcinoma. DISCUSSION: Despite thyroid metastasis being rare, FNAB can prove to be useful tool for diagnosis of thyroid tumors and metastases and can be inconclusive in some cases. Therefore, immunohistochemistry can prove beneficial in diagnosis such cases. CONCLUSION: The diagnosis of renal cell carcinoma metastasis is made after immunohistochemical evaluation of the thyroidectomy specimen with thyroidectomy proving to be the modality of treatment for such cases with no further radiation therapy and a yearly follow up plan to screen for other lesions.

RESUMEN

Ectopic thyroid gland is a rare condition where the thyroid is not placed in the pre-tracheal region. Majority of cases are commonly located at the lingual portion. The malignant shift of ectopic thyroid is considered a rare manifestation with a challenging surgical approach. Here we report our management and surgical approach of a patient with papillary microcarcinoma of sublingual thyroid gland presented to our facility.

RESUMEN

Objective Patients with post-meningitis deafness remain challenging candidates for cochlear implantation (CI) which can be difficult due to fibrosis or ossification of the inner ear, and their outcomes remain doubtful. We assessed the surgical and audiological outcomes of CI in patients with profound sensorineural hearing loss caused by meningitis and compared those outcomes to patients without cochlear ossification. Methods This retrospective cross-sectional study was carried out at King Fahad General Hospital, Jeddah, Saudi Arabia. Among 246 patients who underwent cochlear implantation, 13 patients with post-meningitic deafness were identified (Group 1). A matched control group, including patients with deafness due to other causes who did not have cochlea osteogenesis, was selected (Group 2). For all patients, data were collected from medical records, including surgical and audiological outcomes. Results Sclerosis of the cochlea was high in Group 1 (46.2%). There were no postoperative surgical complications in either group. Responses of the auditory nerve action potential obtained through auditory response telemetry (ART) or the neural response telemetry (NRT) were recorded. There was no significant difference between the two groups regarding the intraoperative and the postoperative ART or NRT at selected electrodes representing the entire cochlea. Likewise, no significant difference regarding the speech recognition test (SRT) was detected. Conclusions Cochlear implantation is a safe procedure without surgical complications in post-meningitis patients. Furthermore, early CI in children was associated with favorable outcomes in terms of preservation of the auditory nerve response, restoration of speech discrimination, and recognition to levels comparable to patients with deafness due to other causes. Early audiological assessment in meningitis patients is recommended to identify hearing loss and eventually to offer CI.
