RESUMEN
PURPOSE: To review surgical outcomes of stapes surgery for otosclerosis with persistence of the stapedial artery. MATERIALS AND METHODS: A retrospective case review of a tertiary neurotology referral center of patient with otosclerosis undergoing primary stapes surgery between 2010 and 2017 found to have a persistent stapedial artery. Stapedectomy was performed with or without cauterization of the stapedial artery. The primary outcome measures include pre- and postoperative hearing as well complications. Hearing was measured by air conduction (AC) and bone conduction (BC) pure-tone averages (PTA), air-bone gap (ABG), and word recognition scores (WRS). Neurologic complications, including facial nerve function, were assessed. RESULTS: Four patients out of 853 with otosclerosis undergoing stapedectomy were found to have a persistence of the stapedial artery. Mean AC PTA was 55 dB preoperatively, and 24 dB postoperatively (p = .0041), while the ABG improved on average from 31 dB to 6 dB (p = .0014). Mean follow-up time was 32 months, and there were no significant complications. Facial nerve function was preserved in all patients (House-Brackmann grade I/VI). CONCLUSIONS: In the case of a persistent stapedial artery, excellent hearing outcomes are achievable for otosclerosis via stapedectomy without an apparent increased risk of neurologic complication.

PURPOSE: In the largest reported United States (U.S.) cohort of benign paroxysmal positional vertigo (BPPV), does the presence or absence of migraine correlate with increased associations of other factors? MATERIALS & METHODS: A retrospective chart review from a single U.S. neurotology center. Adult patients with BPPV from 2003 to 2017 classified into two groups: 1) with migraine; 2) without migraine. RESULTS: The prevalence of self-reported migraine history in a BPPV-positive population (n = 1481) was 25.8% (n = 382). Among those with BPPV and migraine, 88.5% were female, 8.1% had diabetes, 22.5% had prior history of BPPV, 8.9% had Meniere's disease and recurrence rate was 38.3%. No statistically significant differences between recurrence or resolution rates between the two groups were demonstrated (p > 0.05). Adjusted logistic regression model found that women and those with a prior history of BPPV had significantly higher odds of having both BPPV and migraine conditions compared to their counterparts. In contrast, older age and diabetes were associated with significantly lower odds of concomitant BPPV and migraine. CONCLUSIONS: The prevalence of migraine among the study sample was 25.8%. Female gender, prior history of BPPV, younger age, and lack of diabetes were independently associated with the concurrent comorbidity of BPPV and migraine. These data further substantiate previously reported rates (from smaller studies); and, demonstrate that recurrence and resolution rates are not worse in those with BPPV and migraine compared to the general BPPV population. Findings support an association between migraine and BPPV and enhances one's ability to accurately counsel patients regarding these diseases.

OBJECTIVES: To assess the accuracy of pre-operative diagnosis of masses of the cerebellopontine angle (CPA) when compared to surgical pathology. DESIGN: Retrospective chart review. PARTICIPANTS: Patients who underwent surgery for CPA masses at two tertiary care institutions from 2007 to 2017. MAIN OUTCOME MEASURES: Percent concordance between pre-operative and surgical pathologic diagnosis; sensitivity, specificity, positive predictive value, and negative predictive value for predicted diagnoses. RESULTS: Concordance between pre-operative diagnosis and surgical pathology was 93.2% in 411 sampled patients. Concordance was 57.9% for masses other than vestibular schwannoma. Prediction of vestibular schwannoma and meningioma had high positive (0.95 and 0.97, respectively) and negative (0.76 and 0.99, respectively) predictive values. Prediction of facial neuroma had sensitivity of 0.13 and positive predictive value of 0.25. Headache (pâ¯=â¯0.001) and facial weakness (pâ¯=â¯0.003) were significantly associated with different pathologic profiles. Hearing loss was associated with differences in diagnostic prediction (pâ¯=â¯0.02) but not with differences in surgical pathology (pâ¯>â¯0.05). CONCLUSIONS: Comparison between pre-operative predicted diagnosis and surgical pathology for cerebellopontine angle masses is presented. Vestibular schwannoma and meningioma were effectively identified while rarer CPA masses including facial neuroma were rarely identified correctly. Clinicians caring for patients with CPA masses should be mindful of diagnostic uncertainty which may lead to changes in treatment plan or prognosis.

PURPOSE: Benign paroxysmal positional vertigo (BPPV) involving the horizontal and superior semicircular canals is difficult to study due to variability in diagnosis. We aim to compare disease, treatment, and outcome characteristics between patients with BPPV of non-posterior semicircular canals (NP-BPPV) and BPPV involving the posterior canal only (P-BPPV) using the particle repositioning chair as a diagnostic and therapeutic tool. METHODS: Retrospective review of patients diagnosed with and treated for BPPV at a high volume otology institution using the particle repositioning chair. RESULTS: A total of 610 patients with BPPV were identified, 19.0% of whom had NP-BPPV. Patients with NP-BPPV were more likely to have bilateral BPPV (52.6% vs. 27.6%, pâ¯<â¯0.0005) and Meniere's disease (12.1% vs. 5.9%, pâ¯=â¯0.02) and were more likely to have caloric weakness (40.3% vs. 24.3%, pâ¯=â¯0.01). Patients with NP-BPPV required more treatments for BPPV (average 3.4 vs. 2.4, pâ¯=â¯0.01) but did not have a significantly different rate of resolution, rate of recurrence, or time to resolution or recurrence than patients with posterior canal BPPV. CONCLUSIONS: Comparison of NP-BPPV and P-BPPV is presented with reliable diagnosis by the particle repositioning chair. NP-BPPV affects 19% of patients with BPPV, and these patients are more likely to have bilateral BPPV and to require more treatment visits but have similar outcomes to those with P-BPPV. NP-BPPV is common and should be part of the differential diagnosis for patients presenting with positional vertigo.

OBJECTIVE: To report rates of cerebrospinal fluid leak, wound infection, and other complications after repair of retrosigmoid craniotomy with hydroxyapatite bone cement. METHODS: Retrospective case review at tertiary referral center of patients who underwent retrosigmoid craniotomy from 2013 to 2016 with hydroxyapatite cement cranioplasty. OUTCOME MEASURES: Presence of absence of cerebrospinal fluid leak, wound infection, and other complications. RESULTS: Twenty cases of retrosigmoid craniotomy repaired with hydroxyapatite cement were identified. Median length of follow up was 9.8months. No cases of cerebrospinal fluid leak were identified. One patient developed a wound infection which was thought to be related to a chronic inflammatory response to the implanted dural substitute. No other major complications were noted. CONCLUSIONS: A method and case series of suboccipital retrosigmoid cranioplasty using hydroxyapatite cement and a are reported. Hydroxyapatite cement cranioplasty is a safe and effective technique for repair of retrosigmoid craniotomy defects.

OBJECTIVE: Stapes surgery for otosclerosis occasionally requires revision due to recurrent or persistent conductive hearing loss (CHL). This study examines outcomes after revision stapes surgery. STUDY DESIGN: Retrospective review. SETTING: Single tertiary neurotology center. METHODS: Patients undergoing revision stapes surgery for otosclerosis from 2008 to 2017 were reviewed. Postoperative air-bone gaps (ABGs) were the primary outcome measure. RESULTS: During the study period, 150 patients underwent revision stapes surgery. One hundred patients (67%) had gradually progressive recurrent CHL; 16 (11%), sudden recurrent CHL; 13 (9%), persistent CHL; and 21 (14%), no CHL. For 129 patients with CHL, the mean ABG improved from 23.7 to 9.3 dB (P < .0005). The most common intraoperative findings for these patients were prosthesis displacement with incus necrosis (38%) or without it (43%), normal anatomy with seemingly good prosthesis placement (6%), and abundant scar tissue (6%). Patients with recurrent hearing loss achieved lower mean ABGs than patients with persistent hearing loss (8.8 vs 13.2 dB, P = .02). There were no associations between onset pattern of CHL or intraoperative findings and hearing outcomes (P > .05). Four patients (2.7%) developed sensorineural hearing loss after revision, defined as an increase in bone conduction pure tone average ≥15 dB, all of whom had previous replacement of a malpositioned prosthesis. CONCLUSIONS: Revision stapes surgery confers significant improvement in hearing for patients with persistent and recurrent CHL, although patients with persistent CHL after initial surgery see less improvement with revision.

OBJECTIVE: To assess hearing outcomes in observed vestibular schwannoma (VS) with focus on non-growing tumors. STUDY DESIGN: Retrospective review. SETTING: Two tertiary neurotology centers. PATIENTS AND INTERVENTIONS: Patients with sporadic VS undergoing at least 3 years' observation. MAIN OUTCOME MEASURES: Changes in pure tone averages (PTA) and word recognition scores (WRS) normalized to the contralateral ear. RESULTS: During the study period, 39 of 105 included patients (37.1%) had tumor growth. Patients with tumor growth had a mean normalized increase in PTA of 8.0 dB HL ( p = 0.008) corresponding to a normalized average worsening of their PTA of 1.8 dB per year. Patients with non-growing tumors less than 5 mm in maximal dimension did not have significant ongoing normalized hearing loss ( p > 0.05). Patients with non-growing tumors more than or equal to 5 mm had a mean normalized increase in PTA of 7.4 dB HL ( p = 0.001) corresponding to an average of 2.0 dB HL per year, which was similar to the loss observed in growing tumors regardless of size ( p > 0.05). Normalized decline in PTA of at least 5 dB HL was seen in 72% of patients with growing tumors, 53% of patients with nongrowing tumors more than or equal to 5 mm, and 38% of patients with non-growing tumors less than 5 mm. CONCLUSIONS: A long-term analysis of hearing outcomes in observed vestibular schwannoma is presented. With observation, VS more than or equal to 5 mm is associated with continued hearing loss even without tumor growth, while non-growing tumors less than 5 mm are not associated with continuing hearing loss. These data inform expectations for observed VS for providers and patients.

OBJECTIVE: Assess opinions that influence treatment choice for single sided deafness (SSD). STUDY DESIGN: Retrospective chart review. SETTING: Tertiary neurotology referral center. PATIENTS: Patients with SSD were recruited between December 2020 and February 2021. Included patients were self-selected by voluntary completion of the study questionnaire. MAIN OUTCOME MEASURES: Tinnitus Handicap Inventory (THI), Hearing Handicap Inventory for Adults (HHIA), and a questionnaire containing 25 areas of inquiry relevant to management strategy decision making. RESULTS: In comparison to the surgical management group, patients opting for nonsurgical amplification were significantly more concerned about device visibility (pâ=â0.005, 1.32â±â0.22 versus 2.67â±â0.37), undergoing surgery (pâ=â0.017, 1.64â±â0.23 versus 2.89â±â0.51), and the thought of harboring an implanted device (pâ=â0.003, 1.46â±â0.22 versus 2.82â±â0.35). Patients with a major hearing handicap (grade 2-4) placed significantly less emphasis on out-of-pocket costs (pâ=â0.049, 2.38â±â0.17 versus 2.94â±â0.21) and were less concerned about experiencing discomfort from the device (pâ=â0.033, 3.13â±â0.11 versus 3.56â±â0.16) or ease of device use (pâ=â0.040, 3.20â±â0.13 versus 3.63â±â0.13) when compared with the minor handicap group. CONCLUSIONS: Lingering concerns about device visibility, undergoing surgery, and harboring an implanted device underscore the need for thorough patient counseling during SSD device selection consultations. These efforts should aim to address esthetic and surgical risk concerns while emphasizing the potential for improvements in quality of life.

OBJECTIVE: To assess outcomes after surgery for vestibular schwannoma in patients over 70âyears of age. STUDY DESIGN: Retrospective chart review. SETTING: Two tertiary otology and neurotology centers. PATIENTS AND INTERVENTIONS: Patients undergoing primary surgery for vestibular schwannoma between 2007 and 2018. MAIN OUTCOME MEASURES: Postoperative complications and surgical outcomes. RESULTS: A total of 452 patients met inclusion criteria, 31 of whom (6.9%) were over 70âyears of age. Age ranged from 18 to 90âyears with a mean of 53âyears. Elderly patients were more likely to have pre-existing hypertension (58.1% versus 34.0%, pâ=â0.007) and diabetes mellitus (19.4% versus 7.4%, pâ=â0.02). Elderly patients were less likely to undergo gross total resections of their tumors (35.5% versus 60.6%, pâ=â0.05) although they were not statistically significantly more likely to undergo subtotal (<95%) resections (25.8% versus 14.7%, pâ>â0.05). Elderly patients were also less likely to undergo second stage procedures (0% versus 9.5%, pâ=â0.04). There were no significant differences between elderly and non-elderly patients in the rates of any complications, ultimate facial nerve function, or duration of surgery. No patients over 70âyears of age expired within 1âyear of surgery. CONCLUSIONS: Conservative surgery for vestibular schwannoma in appropriately selected elderly patients is appropriate and safe, given adequate consideration to risk-benefit analysis and goals of care.

INTRODUCTION: Hearing loss due to otosclerosis is effectively treated with surgery. The association between duration of hearing loss and surgical outcomes is unknown. STUDY DESIGN: Retrospective review. SETTING: Large otology referral center. METHODS: Patients undergoing primary stapes surgery for otosclerosis from 2005 to 2017 were evaluated according to their self-reported duration of hearing loss. Closure of the air-bone gap (ABG) was the primary outcome measure. RESULTS: A total of 580 stapes operations were included. Sixteen percent of patients reported hearing loss for ≤1 year; 25%, >1 to ≤5 years; 24%, >5 to ≤10 years; 24%, >10 to ≤20 years; and 12%, >20 years, respectively. Average pre- and postoperative ABGs were 26.1 and 9.6 dB (P < .0005). Patients with longer duration of hearing loss had worse preoperative ABGs (P < .0005). After surgery, patients with longer duration of hearing loss had a greater reduction in their ABGs (P < .0005) such that the remaining ABG was not associated with duration of hearing loss (P > .05). There were no significant associations between the duration of hearing loss and complication rates or the need for revision surgery. CONCLUSION: Otosclerosis is effectively treated with surgery even after a long duration of hearing loss, provided that sensorineural hearing and word recognition are favorable. Although far-advanced otosclerosis has known poorer hearing outcomes after stapes surgery, a long duration of hearing loss is an unreliable surrogate for this.

OBJECTIVE/HYPOTHESIS: Stapes surgery is occasionally complicated by an intraoperative tympanic membrane perforation (ITMP), traditionally indicating abortion of the procedure due to concerns for postoperative infection and sensorineural hearing loss (SNHL). This work examines outcomes and complications in completed primary stapes surgeries with and without ITMP. STUDY DESIGN: Retrospective review. METHODS: All patients diagnosed with otosclerosis between February 2008 and September 2017 at a tertiary otology referral center were reviewed retrospectively. Primary outcome measures were post-operative air-bone gap (ABG), air conduction and bone conduction pure tone averages, and post-operative complications. RESULTS: Review revealed 652 primary stapes operations meeting inclusion criteria, of which ITMP occurred in 10. There were no significant differences in pre-operative hearing metrics or demographic characteristics between ears with and without ITMP. There were also no significant differences in post-operative ABG (6.4 vs. 8.0 dB HL, P = .43) or change in ABG after surgery (-21.6 vs. -18.2 dB, P = .34) between these two groups. Patients with ITMP were more likely to complain of post-operative dysgeusia (30.0% vs. 5.3%, P = .015) but were no more likely to develop reparative granuloma, otitis media, or SNHL (P > .05). CONCLUSIONS: The first review of ITMP and hearing outcomes after stapes surgery is presented. Our findings suggest that it is likely safe and appropriate to proceed with primary stapes surgery and concurrent tympanoplasty in the presence of a small ITMP with minimal risk of infection, SNHL, or worsened hearing outcomes.

OBJECTIVE: Review surgical outcomes of stapedectomy for otosclerosis in patients with Menierè's disease. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Patients with otosclerosis and Menière's disease undergoing stapedectomy between 2010 and 2017. INTERVENTION: Stapedectomy. MAIN OUTCOME MEASURES: Pre- and postoperative hearing and complications. Hearing was measured by air conduction (AC) and bone conduction (BC) pure-tone frequency, pure-tone averages (PTA), air-bone gap (ABG), and word recognition scores (WRS). RESULTS: Among 1,499 patients with otosclerosis, the incidence of concomitant Menière's disease was 1.7%. Fifteen patients with otosclerosis and Menière's disease underwent stapedectomy, 12 primary and three revisions. Mean AC PTA was 43âdB preoperatively, and 25âdB postoperatively (pâ=â0.0007), while the ABG improved on average from 20 to 5âdB (pâ=â0.0001). There was no significant difference in BC PTA or WRS postoperatively. Two patients experienced fluctuation of hearing in the postoperative period, one of which resolved with a course of steroids. The mean follow-up time was 41 months. CONCLUSIONS: In patients with otosclerosis and Menière's disease, stapedectomy provides excellent hearing outcomes in a majority of patients. As is characteristic of Menière's disease, some patients will continue to experience fluctuating hearing postoperatively, which may progress to severe sensorineural hearing loss. Menière's disease may not be an absolute contraindication to stapes surgery.

OBJECTIVE: Stapes surgery is highly successful in reducing or eliminating the audiometric air-bone gap (ABG) related to otosclerosis, and it can be performed under general anesthesia or local anesthesia with sedation. Literature on the relative outcomes of these 2 modalities is lacking. The purpose of this study was to compare hearing outcomes for these 2 modalities in a large patient population. STUDY DESIGN: Retrospective review. SETTING: Large otology referral center. METHODS: Patients undergoing primary stapes surgery for otosclerosis from 2005 to 2017 were grouped by anesthetic modality and their cases reviewed. Pre- and postoperative ABGs were primary outcomes. RESULTS: A total of 580 patients undergoing stapes surgery were included: 46% received local anesthesia and 54% received general anesthesia. These 2 groups were similar in demographic and disease characteristics. Mean preoperative ABGs were 25.6 and 26.6 dB for patients undergoing local and general anesthesia, respectively (P = .2); mean postoperative ABGs were 9.5 and 9.7 dB (P = .9). There were no significant differences in the rates of complications, the need for revision surgery, or the need to abort surgery intraoperatively between local and general anesthesia. CONCLUSION: Consistent with limited prior data, in this cohort stapes surgery yielded similar hearing outcomes whether performed under general anesthesia or local anesthesia with sedation. While we report the largest sample size to date, this study, like previous work, carries the potential for sampling bias. Prospective study comparing local and general anesthesia for stapes surgery is needed.

OBJECTIVES: To describe audiologic outcomes following hydroxyapatite bone cement fixation of stapedotomy prostheses. METHODS: A retrospective case review at a tertiary neurotology referral center was performed of patients undergoing primary or revision stapedotomy between 2010 and 2017. Patients with hydroxyapatite bone cement fixation of stapes prostheses were assessed. Pre- and postoperative hearing was compared, consisting of air conduction (AC) and bone conduction (BC) pure-tone averages (PTA), air-bone gap (ABG), and word recognition scores (WRS). Short and long-term outcomes were assessed. RESULTS: Forty-six patients with otosclerosis underwent stapedotomy with bone cement fixation: 21 primary cases and 25 revision cases, with an average follow-up time of 17 months. Mean AC PTA was 56 dB preoperatively, and 34 dB postoperatively (P < .0001), while the ABG improved on average from 27 dB to 9 dB (P < .0001). There was no significant difference in postoperative ABG between primary and revision stapes surgery (6 dB vs 10 dB, P = .07). These results persisted through long-term follow-up in a subgroup of patients with significantly longer follow-up time (mean 44 months). There was no significant change in BC PTA or word recognition scores. Three patients underwent subsequent revisions, one patient developed sensorineural hearing loss. CONCLUSION: Stapedotomy with bone cement fixation of the prosthesis provides excellent hearing outcomes in both primary and revision treatment of otosclerosis. Results are consistent and stable through long-term follow-up. The use of bone cement should be incorporated into the surgical armamentarium of the otologist for the prevention and treatment of loose-wire syndrome and incus necrosis.

OBJECTIVE: To assess complication rates in hydroxyapatite cement (HAC) cranioplasty for translabyrinthine acoustic surgery compared with historical controls. METHODS: Retrospective chart review of patients undergoing de novo translabyrinthine surgery with HAC cranioplasty without concurrent adipose tissue graft or additional material between 2010 and 2017 at a tertiary otology center. RESULTS: Fifty-two patients underwent HAC cranioplasty during the study period. The average length of follow-up was 30.5 months. HAC cranioplasty was associated with acceptable rates of cerebrospinal fluid leak (3.8%), wound or intracranial infection (5.8%), need for unplanned revision surgery (9.6%), and all complications (15.3%). All complications occurred within 5 months of surgery. No delayed wound infections or implant extrusions occurred. CONCLUSION: HAC cranioplasty has an acceptable complication profile for translabyrinthine surgery and is a viable alternative to abdominal fat grafting without associated donor site morbidity. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:206-211, 2020.

OBJECTIVE: To examine patients with residual tumor after vestibular schwannoma (VS) resection with focus on need for further therapy, including stereotactic radiosurgery (SRS) and revision surgery. STUDY DESIGN AND SETTING: Retrospective review at two tertiary otology referral centers. PATIENTS AND INTERVENTION: Patients undergoing primary surgery for VS from 2007 to 2017. MAIN OUTCOME MEASURE: Degree of resection and need for further treatment. RESULTS: Of 289 patients undergoing surgery, 38 (13.1%) underwent subtotal resections (<95% of tumor resected) and 77 (26.6%) underwent near-total resections (≥95% but <100%). Patients with any residual tumor had larger tumors preoperatively (mean estimated volume 6.3âcm versus 2.1âcm, pâ<â0.0005) but were otherwise clinically and demographically similar to the population as a whole. Further treatment (surgery or SRS) was needed in 4.6, 14.3, and 50.0% of patients after gross total, near-total, and subtotal resections, respectively (pâ<â0.0005). Patients undergoing additional therapy had larger residual tumors (median post- to preoperative estimated volume ratio 0.09 versus 0.01, pâ<â0.0005). Patients undergoing subtotal and near-total resections had poorer facial function at ultimate follow up than those undergoing gross total resections (pâ=â0.001), likely due to larger tumors and more difficult resections. Literature review revealed higher rates of gross total resection as well as facial palsy in the pre-SRS era. CONCLUSION: Residual tumor following VS resection is more common today than in the pre-SRS era. Availability of SRS may encourage leaving residual tumor intraoperatively to preserve neural structures. Current surgical strategies decrease surgical morbidity but necessitate further treatment in over 10% of cases.

OBJECTIVES: Elevated body mass index (BMI) is a risk factor for surgical complications, but data in acoustic neuroma surgery are conflicting and limited to small single-institution studies. This work evaluates associations between BMI and complications in surgery for acoustic neuroma (AN). STUDY DESIGN: Retrospective review. SETTING: Two tertiary otology referral institutions. SUBJECTS AND METHODS: Patients undergoing surgery for AN. Univariate and multivariate analysis of association between BMI and complications was performed using two-tailed t tests and binary logistic regression. RESULTS: BMI ranged from 18.0 kg/m2 to 63.9 kg/m2 with mean of 29.2 kg/m2 among 362 included patients. High BMI was associated with increased risk of cerebrospinal fluid (CSF) leak (p = 0.003) and need for revision surgery within 6 months (p = 0.03). CSF leak occurred in 11.6% of obese patients (BMI ≥ 30.0) and 5.1% of patients with BMI < 30.0. There was no association between BMI and post-operative intracranial hemorrhage, wound infection, or incomplete resection (p > 0.05). Multivariate analysis revealed BMI was associated with CSF leak (odds ratio 1.11 per BMI point, p = 0.002) and need for revision surgery (odds ratio 1.07 per BMI point, p = 0.02) independent of age, gender, tumor size, or surgical approach. CONCLUSIONS: The largest series to date investigating BMI in acoustic surgery is presented. Elevated BMI is strongly associated with CSF leak and need for revision surgery but not with other complications. Obese or overweight patients undergoing acoustic neuroma resection should be counseled of their increased risk of CSF leak.

OBJECTIVE: Access to postoperative aural rehabilitation limits cochlear implant (CI) penetration to the candidate population. The purpose of this study was to evaluate the effectiveness of remote CI programming and aural rehabilitation via telehealth. STUDY DESIGN AND SETTING: Retrospective study of one cochlear implant center. PATIENTS AND INTERVENTION: Patients undergoing cochlear implantation from 2015 to 2018 undergoing remote programming as part of routine audiologic follow up. MAIN OUTCOME MEASURES: AzBio scores, impedances, comfort and threshold levels, and responses to the International Outcome Inventory for Hearing Aids questionnaire modified for CIs (IOI-CI). RESULTS: A total of 22 CIs in 20 patients were included during the study period. Threshold, comfort, and impedance levels were readily obtained via telehealth and were not significantly different between telehealth and live sessions. AzBio scores and warble tone pure tone averages were also similar and acceptable in both session modalities. Based on IOI-CI scores, patients were very satisfied with their hearing outcomes. CONCLUSIONS: Using telemedicine, reliable measurements were readily obtained and hearing outcomes after remote programming were comparable to those expected after in-person programming sessions. Patients were overall satisfied with their remote programming sessions. Telehealth is a cost-effective and safe way to deliver post-CI audiologic care, particularly to patients with limited mobility or those in remote locations.

OBJECTIVE: Facial function is a key outcome in surgery of the cerebellopontine angle (CPA). This study describes the natural history of facial weakness after CPA surgery. STUDY DESIGN AND SETTING: Retrospective study of two tertiary centers. PATIENTS AND INTERVENTION: Patients undergoing surgery for CPA tumors from 2003 to 2017 with preoperatively normal facial function and without subsequent surgical or adjuvant therapy. MAIN OUTCOME MEASURE: Serial facial nerve examinations using the House-Brackmann (HB) scale. RESULTS: Of 301 patients examined, 149 (49.5%) had facial weakness postoperatively and 74.5% of these occurred within 24âhours. Of patients with HB-1 function within 24âhours after surgery, 95.3% had HB-1 function and 100% had HB-3 or better function at last follow-up. Of patients with HB-4 or worse function within 24âhours after surgery, 22.6% ultimately achieved HB-1 function and 83.9% ultimately achieved HB-3 or better function. By 180 days postoperatively, 83.7% of patients' facial function had stabilized. At last follow-up, 3.0% of patients had facial function poorer than HB-3, which was associated with subtotal resections (12.9% vs. 4.4% for near total and 0.6% for gross total resections, pâ=â0.002), aspirin use (10.6% vs. 1.6%, pâ=â0.001), larger tumors (pâ<â0.0005), longer surgery (pâ<â0.002), and immediate versus delayed postoperative facial weakness (pâ=â0.002). CONCLUSIONS: Facial function over time after CPA surgery is presented. While facial function immediately after surgery correlates with future function, delayed weakness or improvement is common. These data inform patient counseling both preceding and following surgery.

OBJECTIVES/HYPOTHESIS: A hybrid variation of a tympanoplasty technique, termed over-under tympanoplasty (OUT), was evaluated to demonstrate the long-term outcomes and complications compared to medial tympanoplasty. STUDY DESIGN: Retrospective review. METHODS: Patients who underwent a tympanoplasty between 2010 and 2015 were included. Primary outcome measures included graft healing at 18 months, change in air-bone gap (ABG), and change in high-frequency hearing at 8 kHz. The Shapiro-Wilk test, Student t test, and nonparametric Mann-Whitney test were used to compare results. Univariate logistic regression analysis was used to identify potential predictors of surgical success. RESULTS: One hundred eleven patients were included; 84 underwent the over-under technique and 27 underwent medial tympanoplasty. At the 18-month follow-up, 100% of patients in the medial tympanoplasty group had closure of the TM perforation compared to 84% (71/84) in the over-under group. In the over-under group, 12% of patients developed small or pinpoint perforations, and 4% developed larger, recurrent perforations. Mean improvement in ABG was similar between the two groups (11.6 dB for the medial group vs. 11.9 dB for the over-under group, P < .001). No hearing loss was noted in either group. No lateralization of the graft or anterior blunting was noted. CONCLUSIONS: In this series, the OUT technique had a high success rate with TM perforations, including anterior, near total, and total perforations. Hearing loss from dissection on the malleus was not found. This approach blends the advantages and minimizes the disadvantages of the classic techniques and is well suited for all types of tympanic membrane perforations.
