ABSTRACT
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: The pathophysiology of Meniere's Disease (MD) involves endolymphatic hydrops (ELH) of the inner ear. Magnetic Resonance Imaging (MRI) has been shown to detect ELH, but changes in ELH have been poorly described using this modality. Our objective was to review MRI-measured changes in ELH over time and after medical and/or surgical intervention in patients with MD. We secondarily aim to associate changes in ELH with changes in MD symptomatology. DATABASES REVIEWED: Medline, Web of Science, and Embase databases. METHODS: A systematic review of articles was performed to identify studies utilizing MRI to measure ELH changes over time, and after medical or surgical treatment. Articles on non-human subjects and without direct measurement of ELH were excluded. RESULTS: Of 532 studies identified, 12 were included, involving 170 patients (mean age 56.3 years). Ten studies were prospective; two were retrospective. Five studies strictly utilized medical means of intervention, four utilized surgical treatments, one utilized both, and two observed temporal changes without treatment. Across all interventions, 72.1 % of patients exhibited the same or worsening ELH on imaging. In studies reporting vertigo outcomes, 95.9 % of patients exhibited improvement after the treatment period. CONCLUSION: Medical and surgical interventions often yield symptomatic relief of vertigo in MD patients despite stable or increasing ELH volume. MRI may have greater clinical utility in diagnosing ELH as opposed to assessing treatment response.

OBJECTIVE: To quantify contralateral hearing outcomes after labyrinthectomy for unilateral Ménière's disease (MD). STUDY DESIGN: Retrospective case series. SETTING: Tertiary neurotology referral center. PATIENTS: Labyrinth removal for the management of MD or translabyrinthine (TLAB) acoustic neuroma resection between 2008 and 2012. MAIN OUTCOME MEASURE: Long-term hearing changes via pure tone averages (PTA). RESULTS: Upon comparison of low-frequency PTA (250, 500, 1000 Hz), MD patients experienced a greater degree of hearing loss during the follow-up period when compared to the TLAB lab group (7.54 ± 2.11 dB vs 2.39 ± 1.10 dB, p = 0.035). This difference as attributable to 12 (28.6 %) MD patients experiencing a ≥30 dB increase in low-frequency PTA, whereas none (0.0 %) of the TLAB surpassed this threshold. CONCLUSIONS: At 10 years post-labyrinthectomy there is a heightened risk for MD patients to develop low-frequency sensorineural hearing loss. Clinicians should monitor for audiometric changes through regular testing in the decade following labyrinth removal.

Expansion of a polyglutamine (polyQ) domain within the first exon of the huntingtin (htt) protein is the underlying cause of Huntington's disease, a genetic neurodegenerative disorder. PolyQ expansion triggers htt aggregation into oligomers, fibrils, and inclusions. The 17 N-terminal amino acids (Nt17) of htt-exon1, which directly precede the polyQ domain enhances polyQ fibrillization and functions as a lipid-binding domain. A variety of post-translational modifications occur within Nt17, including oxidation of two methionine residues. Here, the impact of oxidation within Nt17 on htt aggregation both in the presence and absence of lipid membranes was investigated. Treatment with hydrogen peroxide (H2O2) reduced fibril formation in a dose-dependent manner, resulting in shorter fibrils and an increased oligomer population. With excessive H2O2 treatments, fibrils developed a unique morphological feature around their periphery. In the presence of total brain lipid vesicles, H2O2 impacted fibrillization in a similar manner. That is, oligomerization was promoted at the expense of fibril elongation. The interaction of unoxidized and oxidized htt with supported lipid bilayers was directly observed using in situ atomic force microscopy. Without oxidation, granular htt aggregates developed on the bilayer surface. However, in the presence of H2O2, distinct plateau-like regions initially developed on the bilayer surface that gave way to rougher patches containing granular aggregates. Collectively, these observations suggest that oxidation of methionine residues within Nt17 plays a crucial role in both the aggregation of htt and its ability to interact with lipid surfaces.

INTRODUCTION: Achieving anatomic reduction and re-establishing premorbid occlusion in patients with complex maxillomandibular fractures is challenging even for seasoned surgeons. Historically, surgeons have utilized occlusal splints to help establish occlusal relationships before fracture reduction and fixation. These acrylic splints are fabricated from dental impressions and require manual repositioning of tooth bearing segments along the fracture line to reapproximate premorbid occlusion. The process is laborious, requires a dental lab, and is less efficacious in edentulous patients or those with significantly comminuted fractures; as such it has largely fallen out of practice. Recently, with advances in virtual 3D modeling and printing, we demonstrate that occlusal splints can be designed from computed tomography scans, manipulated virtually, and printed without obtaining impressions from the patient. METHODS/RESULTS: In our series of 3 patients with complex maxillomandibular fractures, occlusal splints were created by 1) obtaining maxillofacial computed tomography scans, 2) reducing the fractures virtually, and 3) using orthognathic virtual surgery software to create the splint. The time between planning and delivery of the splint was 4 to 7âdays. These splints were successfully utilized to help establish premorbid occlusion in conjunction with maxillomandibular fixation and aided in expeditious intraoperative fracture reduction and fixation. CONCLUSIONS: In the treatment of complex facial fractures, occlusal splints can be a useful adjunct in the operative reduction and fixation of fractures. With the advent of virtual preoperative surgical planning via 3D modeling and 3D printing, these occlusal splints can be created of a sufficient fidelity to avoid the strict need for dental impressions.

BACKGROUND: Despite strong evidence demonstrating the clinical and economic benefits of minimally invasive surgery (MIS), utilization of MIS in the Medicare population is highly variable and tends to be lower than in the general population. We sought to compare the post-operative and economic outcomes of MIS versus open surgery for seven common surgical procedures in the Medicare population. METHODS: Using the 2014 Medicare Provider Analysis and Review Inpatient Limited Data Set, patients undergoing bariatric, cholecystectomy, colectomy, hysterectomy, inguinal hernia, thoracic, and ventral hernia procedures were identified using DRG and ICD-9 codes. Adjusting for patient demographics and comorbidities, the odds of complication and all-cause 30-day re-admission were compared among patients undergoing MIS versus open surgery stratified by operation type. A generalized linear model was used to calculate the estimated difference in length of stay (LOS), Medicare claim cost, and Medicare reimbursement. RESULTS: Among 233,984 patients, 102,729 patients underwent an open procedure versus 131,255 who underwent an MIS procedure. The incidence of complication after MIS was lower for 5 out of the 7 procedures examined (OR 0.36-0.69). Re-admission was lower for MIS for 6 out of 7 procedures (OR 0.43-0.87). MIS was associated with shorter LOS for 6 procedures (point estimate range 0.35-2.47 days shorter). Medicare claim costs for MIS were lower for 4 (range $3010.23-$4832.74 less per procedure) and Medicare reimbursements were lower for 3 (range $841.10-$939.69 less per procedure). CONCLUSIONS: MIS benefited Medicare patients undergoing a range of surgical procedures. MIS was associated with fewer complications and re-admissions as well as shorter LOS and lower Medicare costs and reimbursements versus open surgery. MIS may represent a better quality and cost proposition in the Medicare population.

BACKGROUND: Patients with human papillomavirus (HPV)-related oropharyngeal cancer (OPC) have improved survival when compared with those with HPV-negative OPC. Unfortunately, the American Joint Committee on Cancer seventh edition (AJCC-7ed) staging system does not account for the prognostic advantage observed with HPV-positive OPC. The purpose of the current study was to validate and compare 2 recently proposed staging systems for HPV-positive OPC. METHODS: Patients treated for HPV-positive OPC from 2005 to 2015 at Johns Hopkins Hospital (JHH) were included for analysis. The International Collaboration on Oropharyngeal cancer Network for Staging (ICON-S) and The University of Texas MD Anderson Cancer Center (MDACC) staging systems were applied and survival was calculated using Kaplan-Meier methods. Cox proportional hazard regression was used to determine the relationship between stage of disease and survival. Models were compared using the Akaike information criterion (AIC). RESULTS: A total of 435 patients were eligible for analysis. There was a dramatic shift in lymph node category and overall stage of disease when ICON-S and MDACC stage were applied to the JHH cohort. There was superior stratification of overall survival and progression-free survival by ICON-S stage. Both proposed models had an improved fit based on AIC scores (P<.001 for both) over the AJCC-7ed. The ICON-S staging system had the lowest AIC score, and thus a better fit within the JHH population. CONCLUSIONS: The current analysis provides external validation for both staging systems in an independent and heterogeneously treated patient population. Although the MDACC staging system is an improvement over the AJCC-7ed, the ICON-S stage provides superior stratification of overall and progression-free survival, thereby supporting its use as the updated AJCC staging system for OPC.

OBJECTIVES: To investigate the quality of life (QOL) of adult Mandarin-speaking Chinese Americans after cochlear implantation (CI) using the cross-culturally adapted Chinese Cochlear Implant Quality of Life-10 (CIQOL-10) Global. STUDY DESIGN: Cross-sectional. SETTING: Tertiary care neurotology practice in New York City. PATIENTS: Thirty adult Mandarin-speaking Chinese Americans (22.8-89.4 yr, mean 48.9 yr) with prelingual (12) or postlingual (18) deafness who underwent CI between 1995 and 2020. All patients were at least 1 year from CI activation. INTERVENTION: CI. MAIN OUTCOMES MEASURES: Chinese CIQOL-10 Global score. RESULTS: There were no detectable differences in mean Chinese CIQOL-10 Global scores between the prelingual (mean 51.9, SD 11.0) and postlingual (mean 44.0, SD 16.4) cohorts (p = 0.1; 95% CI, -2.3 to 18.1; Hedges' g = 0.5). Comparison of the overall cohort (mean 47.1, SD 14.8) with previously published CIQOL-10 Global scores of English-speaking American CI users (mean 51.5, SD 10.4) demonstrated a significant difference (p = 0.02; 95% CI, 0.4-8.4; Hedges' g = 0.4). For the overall cohort, multivariable analysis demonstrated that combined household income (p = 0.007, ß = 7.4; 95% CI, 0.7-14.0) was positively associated with Chinese CIQOL-10 Global scores. CONCLUSIONS: This study is the first to evaluate QOL after CI in Mandarin-speaking Chinese American adults. The CIQOL-10 Global scores of Mandarin-speaking Chinese Americans CI users are significantly worse than those of English-speaking American CI users. Combined household income may be positively associated with QOL in the Mandarin-speaking Chinese American CI population. More resources are needed to assess outcomes and support rehabilitation in this population.

OBJECTIVE: To analyze the effect of visual abstracts versus automated tweets on social media participation in Otology & Neurotology . PATIENTS: N/A. INTERVENTIONS: Introduction of visual abstracts developed by the social media editorial team to established automated tweets created by the dlvr.it computer program on the Otology & Neurotology Twitter account. MAIN OUTCOME MEASURES: Twitter analytics including the number of new followers per month, impressions per tweet, and engagements per tweet. The Kruskal-Wallis analysis of variance test was used to compare means. RESULTS: From October 2016 to October 2017 (average of 20 new followers per month), 101 automated tweets averaged 536 impressions and 16 engagements per tweet. The visual abstract was introduced in November 2017. From November 2017 to November 2020 (average of 39 new followers per month), 447 automated tweets averaged 747 impressions and 22 engagements per tweet, whereas 157 visual abstracts averaged 1977 impressions and 78 engagements per tweet. Automated tweets were discontinued in December 2020. From December 2020 to December 2022 (average of 44 new followers per month), 95 visual abstracts averaged 1893 impressions and 103 engagements per tweet. With the introduction of the visual abstract, the average number of followers, impressions per tweet, and engagements per tweet significantly increased (all p -values <0.01; all large effect sizes of 0.16, 0.47, and 0.47, respectively). CONCLUSIONS: Visual abstracts created by a social media editorial team have a positive impact on social media participation in the field of otology and neurotology. The impact is greater than that of social media content generated by Twitter automation tools.

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: 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.

OBJECTIVE: Personal statements (PSs) and letters of recommendation (LORs) are critical components of the neurotology fellowship application process but can be subject to implicit biases. This study evaluated general and deep learning linguistic differences between the applicant genders over a 10-year span. STUDY DESIGN: Retrospective cohort. SETTING: Two institutions. MAIN OUTCOME MEASURES: PSs and LORs were collected from 2014 to 2023 from two institutions. The Valence Aware Dictionary and Sentiment Reasoner (VADER) natural language processing (NLP) package was used to compare the positive or negative sentiment in LORs and PSs. Next, the deep learning tool, Empath, categorized the text into scores, and Wilcoxon rank sum tests were performed for comparisons between applicant gender. RESULTS: Among 177 applicants over 10 years, 120 were males and 57 were females. There were no differences in word count or VADER sentiment scores between genders for both LORs and PSs. However, among Empath sentiment categories, male applicants had more words of trust ( p = 0.03) and leadership ( p = 0.002) in LORs. Temporally, the trends show a consistently higher VADER sentiment and Empath "trust" and "leader" in male LORs from 2014 to 2019, after which there was no statistical significance in sentiment scores between genders, and females even have higher scores of trust and leadership in 2023. CONCLUSIONS: Linguistic content overall favored male applicants because they were more frequently described as trustworthy and leaders. However, the temporal analysis of linguistic differences between male and female applicants found an encouraging trend suggesting a reduction of gender bias in recent years, mirroring an increased composition of women in neurotology over time.

The retrosigmoid corridor provides the most broadly applied approach for resection of sporadic vestibular schwannoma. It may be utilized for any size tumor and for patients with intact hearing with the intention of hearing preservation. For larger tumors, the skull base surgeon must weigh the benefits the retrosigmoid approach against those of the translabyrinthine route. For smaller tumors where hearing preservation is a goal, the retrosigmoid approach is contrasted to the middle fossa route. Hearing preservation is most likely for patients with small and medially located intracanalicular tumors with minimal extension into the cerebellopontine angle, and excellent preoperative hearing.

OBJECTIVE: To report on the novel use of simultaneous cochlear implantation (CI) during salvage translabyrinthine resection of vestibular schwannoma (VS) after failed stereotactic radiosurgery (SRS). PATIENT: A 52-year-old woman presented with a medium-sized right VS. She experienced continued tumor growth despite previous SRS, resulting in medial extension beyond the internal auditory canal into the cerebellopontine angle. Associated symptoms included asymmetrical right moderate to severe sensorineural hearing loss, poor word recognition, tinnitus, and dizziness. INTERVENTION: Simultaneous CI with translabyrinthine VS resection. MAIN OUTCOME MEASURE: CI-aided pure-tone averages. RESULTS: After 4 months of device use, CI-aided speech audiometry revealed hearing thresholds in the normal range, with a four-tone pure-tone, average of 16.3 dB. Speech perception with consonant-nucleus-consonant testing in the CI-only condition was 46%, representing a 12% improvement compared with preoperatively. Tinnitus and dizziness burden were subjectively reduced. CONCLUSIONS: Despite challenges inherent to second procedures after radiotherapy failure, successful CI outcomes can be achieved. The current study demonstrates the feasibility of simultaneous CI during salvage VS resection after SRS. A larger study should be undertaken to further substantiate these preliminary findings.

OBJECTIVE: To determine the rate of device failure for those cochlear implants falling under the 2020 Food and Drug Administration (FDA) voluntary corrective action. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary otology-neurotology practice. PATIENTS: Those with cochlear implant failure falling under the FDA corrective action. INTERVENTIONS: Cochlear implant explant and reimplantation. OUTCOME MEASURES: Reason for cochlear implant failure, time to failure, symptoms of failure, and benefit from reimplantation. RESULTS: The overall failure rate was 20.0% (18 of 90 ears); of the failures, 15 of 18 (83.3%) were hard device failures, and 3 of 18 (16.7%) were medical or surgical failures. All hard device failures were confirmed with integrity testing as performed by the company. The average time to integrity testing was 38.0 months. Of the hard failures, 14 of 15 had successful initial activation and benefit. Lack of expected progress was seen in 7 of 15 and a sudden decline in function in 8 of 15. Electrodes 9 to 16 were most often defunct. Significant drops in speech perception were often seen in device failure cases. Three medical/surgical failures were explanted; one had migration of the receiver/stimulator causing discomfort, and the other two had electrode migration after partial insertion. Of the reimplanted patients, 11 of 12 are deriving benefit from their new devices. CONCLUSIONS: The rate of device failure for the cochlear implants of interest is significantly higher in our series than reported in the initial FDA voluntary field corrective action publication.

OBJECTIVE: Quantify the learning curve for endoscopic ear skills acquisition in otolaryngology residents using a simulator. The secondary objective was to determine if demographic factors or previous endoscopic experience influenced skill development. STUDY DESIGN: Prospective, multicenter study. Resident participants each completed 10 amassed trials using a validated endoscopic ear skill trainer. SETTING: Two academic teaching hospitals. SUBJECTS: Otolaryngology residents. MAIN OUTCOME MEASURES: Trial completion times; rate of improvement over time. RESULTS: Thirty-eight residents completed the study, 26 from program A and 12 from program B. Fifteen participants were women and 23 were men. Mean age was 30 years old (range 26 to 34 years). Previous experience with otoendoscopy (B = -16.7, p = 0.005) and sinus endoscopy (B = -23.4, p = 0.001) independently correlated with lower overall trial times. Age, gender, postgraduate year, handedness, interest in otology, and video gaming were not associated with trial times. On multivariate logistic regression, resident completion times improved with trial number, and residents without previous endoscopy experience improved at a faster rate than those with experience ( p < 0.001). CONCLUSIONS: Novice surgeons may acquire basic endoscopic ear experience with self-directed simulation training. The learning curve for transcanal endoscopic ear surgery is comparable to those demonstrated for other otologic surgeries, and specific task competencies can be achieved within 10 trials, suggesting that previous experiences, or lack thereof, may not dictate the ability to acquire new skills. There may be a translational value to previous endoscopic sinus experience on learning transcanal endoscopic ear surgery.

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: To conduct the Chinese cross-cultural adaptation of the Cochlear Implant Quality of Life-10 Global (CIQOL-10 Global) instrument. PATIENTS: Bilingual Chinese American cochlear implant users. INTERVENTION: Chinese cross-cultural adaptation of the CIQOL-10 Global. MAIN OUTCOME MEASURE: Description of the process of Chinese cross-cultural adaptation of the CIQOL-10 Global and pilot testing of the Chinese CIQOL-10 Global in the target patient population. RESULTS: The CIQOL-10 Global was cross-culturally adapted into Chinese. Ten participants were recruited for pilot testing. There was wide representation from across the target population in terms of age (mean, 44.8 yr; range, 20.2-80.3 yr), sex (5 were male, 5 were female), education, and socioeconomic factors. All participants were able to easily read, comprehend, and fill out the Chinese CIQOL-10 Global. CONCLUSIONS: The Chinese version of the CIQOL-10 Global is now available to provide an overall assessment of quality of life of Chinese-speaking cochlear implant users.

OBJECTIVE: To determine the clinical outcomes of adult patients with single-sided deafness (SSD) undergoing ipsilateral cochlear implantation. DATA SOURCE: An electronic search of Medline and Embase articles. REVIEW METHODS: A systematic review was performed with a search strategy developed by a licensed librarian to identify studies of adult patients with SSD who underwent ipsilateral cochlear implantation. Articles were managed in Covidence and evaluated by 2 independent reviewers. Risk of bias was assessed and data were extracted, including patient demographics, etiology of deafness, duration of deafness, and postoperative change in speech recognition, tinnitus, sound localization, and quality of life (QoL). A meta-analysis was performed, and pooled mean differences were calculated for each outcome of interest via random effects models by each outcome, as well as subgroup analyses by the individual clinical score used. RESULTS: Of 2309 studies identified, 185 full texts were evaluated, and 50 were ultimately included involving 674 patients. Speech perception scores in quiet and noise, tinnitus control, sound localization, and QoL all significantly improved after implantation. Pooled outcomes demonstrated score improvements in speech perception (standardized mean difference [SMD], 2.8 [95% CI, 2.16-3.43]), QoL (SMD, 0.68 [95% CI, 0.45-0.91]), sound localization (SMD, -1.13 [95% CI, -1.68 to -0.57]), and tinnitus score reduction (SMD, -1.32 [95% CI, -1.85 to -0.80]). CONCLUSIONS: Cochlear implantation in adults with SSD results in significant improvements in speech perception, tinnitus control, sound localization, and QoL.
