Relevance of the Activities-Specific Balance Confidence (ABC) Scale to Urban Community-Dwelling Adults With Diagnosed Vestibular Dysfunction.

OBJECTIVE: To determine how relevant the items on the activities-specific balance confidence (ABC) scale are to patients living in an urban setting and to evaluate additional items relevant to urban populations but not included in the current version of the scale. DESIGN: Cross-sectional clinical survey. SETTING: Urban, tertiary vestibular rehabilitation clinic. PARTICIPANTS: Vestibular rehabilitation clinic outpatients (N=103). INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Relevance of 16 day-to-day tasks on the ABC scale on a scale of 0 (not performed) to 10 (performed regularly); median relevancy score (MRS) for most relevant items. RESULTS: One hundred three participants (73.7% female, mean age 61.5± years) with vestibular disorders completed the survey. The items with the highest MRS were walking around a house (MRS=10), reaching for a shelved item eye level (MRS=9), taking the stairs (MRS=7), bending over and picking up a slipper (MRS=7), and stepping onto or off an escalator while holding the railing (MRS=7). Lowest MRS items to someone living in an urban environment included walking across a parking lot to the mall (MRS=0) and walking outside the house to a car parked in the driveway (MRS=0). The most common functional activities not addressed by ABC score included navigating the subway/public transit (35.9%) and walking through crowds (32.0%). CONCLUSIONS: This study revealed insights about important activities of daily living for those in an urban setting. Results show that the ABC scale should be modified to better reflect the specific activities of urban dwellers.

Temporal changes in endolymphatic hydrops on MRI with or without intervention: A systematic review.

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.

Does "Just in Time" teaching of ergonomic principles improve posture of trainees during otologic microscopic surgery?

PURPOSE: Musculoskeletal disorders are prevalent among otolaryngologists and otologists with symptoms starting during residency. Prior data suggested that high-risk joint angles were often adopted at procedure onset, suggesting a detrimental "natural" operating position. Despite its importance, dedicated ergonomic teaching is not systematically introduced into residency training. The objective of this study was to compare initial ergonomic positioning during microscopic temporal bone surgery between those who receive "Just in Time" ergonomic teaching prior to starting dissection with those who did not. MATERIALS AND METHODS: This was a pilot, prospective trial in which otolaryngology residents at an urban, multicenter tertiary care academic institution (n = 14) wore ergonomic sensors (inertial measurement units) during microscopic temporal bone lab drilling. Prior to recording, participants were randomized to receive an instructional presentation on ergonomic principles (n = 8, intervention group) or not (n = 6, control group). The inertial measurement units analyzed neck and back angles for the initial 5 min of drilling. RESULTS: Of 14 trainees, 78.6 % had prior experience with otologic microscopic cases and 14.3 % reported prior surgical ergonomic training or instruction. The groups were matched in trainee height (P = 0.54), handedness (P = 0.83), stage of otolaryngology training (P = 0.64), prior otologic microscopic surgery experience (P = 0.35), prior temporal bone drilling experience (P = 0.35), and prior teaching in ergonomic principles (P = 0.47). Junior trainees (PGY 1-3) who did not receive "Just in Time" teaching adopted a posture with significantly higher risk back flexion compared to junior trainees who received the training (25.3° vs. 5.7°, P = 0.04). There was no difference in back positioning among senior trainees (12.6° vs. -5.7°, P = 0.13). While there was a trend towards those in the intervention group adopting safer procedural posture, there was no significant difference in the overall cohort between the intervention and control groups in both neck positioning (-11.0° vs. -19.1°, P = 0.17) and back positioning (8.6° vs. 19.1°, P = 0.18). CONCLUSIONS: Musculoskeletal related pain is prevalent among otolaryngologists and otologists with data suggesting that symptoms begin during residency. Targeted "Just in Time" teaching of ergonomic principles is feasible and may be effective for development of healthy postural habits, especially among junior trainees.

Does Auditory Environment Predict Speech Perception Outcomes in Elderly Cochlear Implant Patients?

INTRODUCTION: Cochlear implantation (CI) is a reliable and safe means by which sensorineural hearing loss can be ameliorated in the elderly population. However, a high degree of variation exists in postimplantation hearing outcomes for which some modifiable factors of the daily natural auditory environment may be contributory. In this study, we analyze the relationship between cochlear implant patient age, natural auditory environment, and postimplantation speech perception among older adults. METHODS: Data log from automatic environment classification enabled sound processors of postlingually deafened CI recipients ≥50 years old (n = 115) were obtained retrospectively and analyzed for time spent (hours per day) in listening environment and loudness (SPL dB). Speech perception testing was assessed in a subset of patients (n = 27) using open-set word recognition in quiet Consonant-Nucleus-Consonant in the short and intermediate postoperative period. RESULTS: The mean subject age was 70 years (range, 53-99 years). Average daily implant use was 10.8 h and was not significantly correlated with age (p = 0.23, Spearman's rho). Age was positively correlated with the percentage of hours spent at <40 and 40-50 dB and negatively correlated to proportional CI use at higher volume (60-70, 70-80, and >80 dB; rs = 0.21, 0.20, -0.20, -0.35, -0.43; p = 0.021, 0.036, 0.033, <0.001, <0.001, respectively). Age was positively correlated with CI use in the quiet scene (rs = 0.26, p = 0.006) and negatively correlated with scenes containing speech and noise (rs = -0.19, -0.25; p = 0.046, 0.007). Total hours of device use and time spent at <40, 40-50 dB, and quiet environments were significantly correlated with improved CNC word scores (rs = 0.48, 0.48, 0.51; p = 0.01, 0.01, <0.01, Spearman's rho). While all speech (speech in noise + speech) was not significantly correlated to improvements in speech perception, a medium effect size was observed (rs = 0.37, p = 0.057). DISCUSSION/CONCLUSION: This study supports a relationship between auditory environment and age, with older CI recipients spending a greater proportion of time in quiet. Older CI users demonstrated greater improvements in speech perception with longer daily device use. Additional examination of the relationship between auditory environment and speech perception is necessary to conclusively guide future auditory rehabilitation efforts.

The utility of augmented reality in lateral skull base surgery: A preliminary report.

OBJECTIVE: To discuss the utility of augmented reality in lateral skull base surgery. PATIENTS: Those undergoing lateral skull base surgery at our institution. INTERVENTION(S): Cerebellopontine angle tumor resection using an augmented reality interface. MAIN OUTCOME MEASURE(S): Ease of use, utility of, and future directions of augmented reality in lateral skull base surgery. RESULTS: Anecdotally we have found an augmented reality interface helpful in simulating cerebellopontine angle tumor resection as well as assisting in planning the incision and craniotomy. CONCLUSIONS: Augmented reality has the potential to be a useful adjunct in lateral skull base surgery, but more study is needed with large series.

Atypical Schwannoma: A 10-year experience.

OBJECTIVE: The goal of this study was to describe the clinical presentation associated with atypical schwannoma of the cerebellopontine angle, characterize the pathologic findings and describe the long-term outcome. MATERIALS AND METHODS: The study design was retrospective case review of patients with the histopathologic diagnosis of atypical and benign schwannoma of the cerebellopontine angle diagnosed at the study institution over a 10-year period. SETTING: Tertiary referral center. MAIN OUTCOMES MEASURE: Demographic data of the cohort were recorded. Findings on pathology were evaluated. Initial treatment and post-operative course was recorded. Main outcome measures were clinical presentation, including cranial nerve deficits at the time of presentation, complication and recurrence rates. RESULTS: At presentation, a somewhat accelerated course of cranial nerve deficit was noted among patients with atypical schwannoma as compared to benign schwannoma. In the immediate post-operative period, there were no differences noted in the complication rate. Atypical schwannomas appear to have higher recurrence rate compared to benign schwannomas. CONCLUSIONS: Atypical schwannoma is an intermediate disease process with an accelerated clinical course and higher recurrence rate as compared to vestibular schwannoma. Traditional operative approaches may be employed without increased concern for post-operative complications. Thorough counseling and close follow-up should be offered to these patients given the higher recurrence rate. Larger studies are required to determine if these patients need more frequent MRIs for long-term surveillance.

National 30-day readmission and prolonged length of stay after vestibular schwannoma surgery: Analysis of the Nationwide Readmissions Database.

PURPOSE: To determine the risk factors for unanticipated readmission, prolonged index admission, and discharge to a facility after vestibular schwannoma surgery. MATERIALS AND METHODS: Retrospective cohort study of those undergoing surgery for vestibular schwannoma in the Nationwide Readmissions Database (2013-2014). Main outcome measures included readmission rate, length of stay, discharge destination. RESULTS: There were 4585 cases identified. The overall unanticipated readmission rate was 8.1%, and 9.1% had a prolonged length of stay (PLOS) of ≥7 days. Mean and median LOS were 4.63 and 4.00 days, respectively, and >90% of patients were discharged after 7 days. Disposition to a facility occurred in 6.7% of cases. Teaching hospitals were protective against unintended readmission (odds ratio [OR] 0.44, p < .001). Major functional loss was associated with PLOS (OR 12.55, p < .001). High volume centers were associated with decreased risk of PLOS (OR 0.46, p < .001) and facility discharge (OR 0.68, p < .001). The most common readmission diagnoses included "other nervous system complications" (n = 128), cerebrospinal fluid leak (n = 71), "other postoperative infection" (n = 61), and meningitis (n = 59). CONCLUSIONS: Unanticipated readmission and prolonged LOS following vestibular schwannoma surgery are common, with varied sociodemographic, hospital, and patient factors independently associated with each. Further studies are needed to investigate targeted interventions aimed at minimizing readmission and prolonged LOS using the factors outlined above.

Impact of Cochlear Implantation on Quality of Life in Chinese Americans.

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.

Long-term outcomes following pediatric endoscopic titanium ossiculoplasty: A single-institution experience.

INTRODUCTION: Endoscopic ossicular chain reconstruction (OCR) in adults has demonstrated equivalent outcomes to the traditional microscopic approach. Less data exist on endoscopic OCR outcomes in children, who have unique considerations including a smaller transcanal corridor and variable pathology. The purpose of this study was to investigate surgical and audiometric outcomes in children undergoing fully endoscopic and endoscopic-assisted OCR in both the short and long-term. METHODS: Retrospective review of all children (<17 years) who underwent endoscopic OCR at one tertiary care center between 2017 and 2021. Children undergoing primary and revision endoscopic OCR with either partial (PORP) and total ossicular reconstruction prostheses (TORP) were included. Children undergoing surgery for juvenile otosclerosis or congenital stapes fixation, or any child receiving a stapes prosthesis were excluded. Primary outcome measures were post-operative change in 4 frequency (500 Hz, 1, 2, 4 KHz) air conduction pure tone average (AC PTA) and change in air-bone gap (ABG). Secondary measures included need for readmission and/or revision surgery, complication rate, and surgery duration. RESULTS: Seventeen patients met inclusion criteria. Average age was 11.3 years (range, 5-17 years); 14 were male. A variety of fixed length, titanium total and partial prostheses were used. The most common prosthesis length was 2 mm (range 2-5 mm), and there were no intra- or perioperative complications. Mean long-term follow-up was 2.6 years. Most common pathology was congenital cholesteatoma (11/17, 64%), followed by chronic otitis media with tympanic membrane perforation (5/17, 29.4%), and extruded prosthesis (1/17, 5.9%). Intraoperatively, the most common finding was incus erosion (10/17, 58.8%), followed by malleus erosion (6/17, 35.3%), stapes erosion (4/17, 23.5%), and stapes absence (4/17, 23.5%). Eight children (47%) were reconstructed with PORPs, and 9 children (52.9%) were reconstructed with TORPs. Average ABG improved from 36.8 dB preoperatively to 19.9 dB postoperatively in the short-term and remained stable at 19.5 dB in the long-term. Average short-term ABG improvement was 4.2 dB for PORPs and 18 dB for TORPs. In the long-term, average ABG improved by 2.3 dB in PORPs and 13.4 dB in TORPs. PORPs had higher rates of ABG closure and lower AC PTAs than TORPs in the long-term. DISCUSSION: Endoscopic ossiculoplasty is a viable option in children presenting with ossicular erosion from various causes. Audiometric improvement following endoscopic partial and total ossicular reconstruction remains stable over time, with a preference towards partial in the long-term, and mirrors published outcomes for microscopic surgery.

Cochlear Implant Device Failures Falling Under the 2020 FDA Voluntary Field Corrective Action: A Systematic Review and Meta-analysis.

OBJECTIVE: To compare the rate of device failure for those cochlear implants (CIs) involved in the 2020 Food and Drug Administration (FDA) voluntary field corrective action (VFCA). DATABASES REVIEWED: Medline, Embase, and Scopus. METHODS: A systematic review was performed according to the PRISMA guidelines. Publications reporting institutional experiences with implants affected by the VFCA were included. Outcomes assessed included etiology of, rate of, and time to failure and pre-/post-device failure speech perception testing. All outcomes reported in at least two independent studies were included in a meta-analysis. RESULTS: Six studies met criteria for analysis. The overall pooled failure rate was 23.7% (95% CI, 11.6-38.4%). The pooled device, inconclusive, and medical failure rates were 21.5%, 0.2%, and 0.7%, respectively. Pediatric failure rates were higher than those of adults (46.9% [95% CI, 11.2-84.5%] versus 32.6% [95% CI, 8.2-63.7%]). WRS declined with primary implant failure (55.1% [95% CI, 48.0-62.1%] to 34.1% [95% CI, 30.2-38.0%]) but improved after reimplantation (34.1% [95% CI, 30.2-38.0%] to 50.1% [95% CI, 45.2-55.1%]). CONCLUSIONS: The rate of pooled reported failure for CIs falling under the 2020 VFCA in the literature thus far is 23.7%. The overwhelming majority of these failures were device related, the rates of which were higher in children. Speech perception improved significantly after reimplantation.

Cost-Effectiveness of Diffusion-Weighted Magnetic Resonance Imaging Versus Second-Look Surgery in Treating Cholesteatoma: A Modeling Study.

OBJECTIVE: To evaluate whether canal wall-up (CWU) tympanomastoidectomy with diffusion-weighted magnetic resonance imaging (DW-MRI) is a cost-effective method of treating cholesteatoma compared with CWU with second-look surgery. DESIGN AND SETTING: Cost-effectiveness analysis was conducted using a Markov state transition model. The simulation model adhered to the Panel Recommendations on Cost-Effectiveness in Health and Medicine established by the US Public Health Service. One-way and Monte Carlo probability sensitivity analyses were conducted for validation. INTERVENTIONS: Tympanomastoidectomy with DW-MRI versus tympanomastoidectomy with second-look surgery. MAIN OUTCOME MEASURES: Effectiveness and health utility were measured using quality-adjusted life years (QALYs). Costs were derived from Medicare reimbursement using the perspective of the payer. Probabilities for outcomes and complications were taken from existing literature. Cost-effectiveness was assessed using the incremental cost-effectiveness ratio. RESULTS: With base case analysis, the total cost was $15,069 when treated with CWU and second-look surgery versus $13,126 when treated with CWU and DW-MRI. The second-look treatment pathway yielded 17.05 QALYs, whereas the DW-MRI pathway yielded 16.91 QALYs in terms of health benefit accrued across the lifetime of the patient. The cost-effectiveness incremental cost-effectiveness ratio was $21,800/QALY. Using the conventional $50,000 willingness-to-pay threshold, second-look surgery was the more cost-effective approach 63.7% of the time by simulation. CONCLUSIONS: Both treatment pathways were found to be cost-effective, with second-look surgery incrementally cost-effective 63.7% of the time. Assumptions were validated by one-way and Monte Carlo probability sensitivity analysis. PROFESSIONAL PRACTICE GAP AND EDUCATIONAL NEED: There is ample variation in treatment pathways regarding usage of DW-MRI and second-look surgery for cholesteatoma. LEARNING OBJECTIVE: To evaluate the cost-effectiveness of DW-MRI and second-look surgery approaches, accounting for health-related quality-of-life outcomes and costs for the duration of the patient lifetimes. DESIRED RESULT: To inform the discussion on the treatment for cholesteatoma given emergent noninvasive technologies.Level of Evidence: Level III.Indicate IRB or IACUC: Exempt.

The Role of Lumbar Drains in the Perioperative Management of Primary Spontaneous Temporal Lobe Encephaloceles and Cerebrospinal Fluid Leaks.

OBJECTIVE: To examine the role of lumbar drains (LDs) in the success of spontaneous temporal cerebrospinal fluid (CSF) leak and encephalocele repair. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic health system. PATIENTS: Patients undergoing repair of spontaneous temporal lobe encephaloceles or middle fossa CSF leaks during years 2017 to 2023. INTERVENTIONS: Transmastoid, middle fossa craniotomy, or combination approaches to CSF leak repair. OUTCOME MEASURES: Failure rate, complication rate, length of stay (LOS), readmission. RESULTS: Sixty-nine patients were included, with a combination approach performed in 78.3%, transmastoid in 17.4%, and isolated middle fossa craniotomy in 4.3%. Mean body mass index was 33.2, mean bony defect size width was 6.51 mm, and defect locations included the epitympanum, antrum, mastoid, and petrous apex. Multilayer closure with three or more layers was performed in 87.0%. LD was used in 73.9% of cases for a mean duration 2.27 days and was associated with longer LOS (3.27 vs. 1.56 d, p = 0.006) but not with failure rate, complications, discharge destination, or readmission. Only one major complication occurred as a result of the drain, but low-pressure headache was anecdotally common. CONCLUSIONS: Use of LD in the repair of spontaneous CSF leaks and temporal lobe encephaloceles is associated with longer LOS but not failure rates or other admission-level outcomes.

Use of Soft Cervical Collar Improves Surgeon Ergonomics During Simulated Otologic Surgery.

OBJECTIVE: To determine whether surgeon use of a soft cervical collar during endoscopic and microscopic otologic surgery is feasible and impacts surgeon ergonomics as measured by inertial sensors. STUDY DESIGN: Prospective crossover trial. SETTING: US-based otolaryngology training program. PATIENTS: Otolaryngology residents and fellows. INTERVENTIONS: Therapeutic-use of a soft cervical collar during simulated otologic surgery. MAIN OUTCOME MEASURES: Time spent in high-risk angles of neck and back flexion and extension; average angle of neck flexion, extension, rotation, and lateral bending; validated assessment of neck pain; average daily phone use. RESULTS: Fifteen subjects met criteria for inclusion. Ten of 15 (67%) were male. Seven of 15 (47%) were postgraduate year 1-2. Seven of 15 (47%) reported a history of neck pain. None reported prior spinal steroid injections or surgery. Across all subjects, use of the soft cervical collar significantly reduced time spent in high-risk angles of neck flexion/extension during both endoscopic (56% vs. 35%, p < 0.05) and microscopic (60% vs. 32%, p < 0.05) otologic surgery. There was no effect on back flexion or extension. There was no difference in time spent in high-risk neck or back angles between endoscopic and microscopic surgery. Average angles of neck or back flexion, extension, lateral bending, and rotation were not significantly different for subgroups with more operative experience, increased phone use, perception of good posture, or history of neck pain. CONCLUSIONS: Use of a soft cervical collar during simulated otologic surgery significantly reduced time spent in high-risk neck positions. These data support feasibility of soft collar use during otologic surgery and hold promise for reduction in the high rates of neck pain reported by neurotologists. PROFESSIONAL PRACTICE GAP AND EDUCATIONAL NEED: Improving surgeon ergonomics for otologic surgery. LEARNING OBJECTIVE: To identify a therapeutic intervention to mitigate neck pain in surgeons caused by assumption of high-risk cervical neck flexion and extension. DESIRED RESULT: To demonstrate that use of a readily available soft cervical collar reduces risk of neck pain in otologic surgeons. LEVEL OF EVIDENCE: II. INDICATE IRB OR IACUC: Exempt.

Augmentative and alternative communication (AAC) in pediatric cochlear implant recipients with complex needs: A scoping review.

INTRODUCTION: Augmentative and alternative communication (AAC) encompasses all forms of unaided and aided modes of communication, but typically excludes codified language such as spoken words or American Sign Language (ASL). In pediatric patients with a documented additional disability (population of interest), deficits in communication may pose a barrier to language development. While forms of AAC are frequently mentioned in the literature, recent innovations have permitted the use of high-tech AAC in the rehabilitation process. Our objective was to review the implementation of AAC in pediatric cochlear implant recipients with a documented additional disability. METHODS: A scoping review of existing literature examining the use of AAC in pediatric CI recipients was conducted in the PubMed/MEDLINE and Embase databases. Studies with pediatric cochlear implant recipients with a concomitant diagnosis requiring additional therapeutic intervention outside the scope of standard post-CI follow-up care and rehabilitation from 1985 to 2021 met inclusion criteria (population of interest). Studies limited to spoken or formal sign language (e.g., American Sign Language, ASL) as communication modalities were excluded. RESULTS: Four hundred twenty studies were screened of which 29 were included. 13 were prospective, 10 were retrospective, 1 was cross-sectional, and 5 were case reports. Of these 29 studies, 378 patients met the inclusion criteria (age <18, CI user, additional disability, utilized AAC). Fewer studies (n = 7) utilized AAC as the primary intervention for investigation. Autism spectrum disorder, learning disorder, and cognitive delay were frequently mentioned as additional disabilities in conjunction with AAC. Unaided forms of AAC included gesture/behavior, informal sign, and signed exact English, while aided AAC included a Picture Exchange Communication System (PECS), Voice Output Communication Aids (VOCA), and touchscreen programs such as TouchChat® HD. Various audiometric and language development outcome measures were mentioned, most commonly the Peabody Picture Vocabulary Test (PPVT) (n = 4) and the Preschool Language Scale, Fourth Edition (PLS-4) (n = 4). CONCLUSION: There is a gap in the literature regarding the use of aided and high-tech AAC in pediatric CI users with a documented additional disability. Given the use of multiple different outcome measures, additional exploration of the intervention of AAC is warranted.

Translabyrinthine Approach for Sporadic Vestibular Schwannoma: Patient Selection, Technical Pearls, and Patient Outcomes.

Defining the Learning Curve for Endoscopic Ear Skills Using a Modular Trainer: A Multi-Institutional Study.

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.

Institutional Experience With Cochlear Implants Falling Under the 2020 FDA Corrective Action.

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.

Development and Chinese Cross-Cultural Adaptation of the Cochlear Implant Quality-of-Life Survey.

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.

Cochlear Implantation in Adults With Single-Sided Deafness: A Systematic Review and Meta-analysis.

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.
