RESUMO
PURPOSE: Intralabyrinthine schwannomas (ILS) are rare, benign, slow-growing tumors arising from schwann cells of the cochlear or vestibular nerves within the bony labyrinth. This study provides insight into the management of this rare tumor through a large case series. MATERIALS AND METHODS: After Institutional Review Board approval, a retrospective chart review was performed of all ILS patients treated at our institution between 2007 and 2019. RESULTS: 20 patients (9 male, 11 female) with ILS were managed at our institution. The right ear was affected in 9 patients (45%) and the left in 11 (55%). Subjective hearing loss was endorsed by all 20 patients. Average pure tone average at presentation was 72 dB nHL. Nine tumors (45%) were intravestibular, 6 (30%) were intracochlear, 4 (20%) were transmodiolar and 1 (5%) was intravestibulocochlear. Hearings aids were used in 3 patients (15%), BiCROS in 2 (10%), CI in 2 (10%), and bone conduction implant in 1 (5%). Vestibular rehabilitation was pursued in 5 patients. Surgical excision was performed for one patient (5%) via translabyrinthine approach due to intractable vertigo. No patients received radiotherapy or intratympanic gentamicin injections. CONCLUSION: ILS presents a diagnostic and management challenge given the similarity of symptoms with other disorders and limited treatment options. Hearing loss may be managed on a case-by-case basis according to patient symptoms while vestibular loss may be mitigated with vestibular therapy. Surgical excision may be considered in patients with intractable vertigo, severe hearing loss with concurrent CI placement, or in other case-by-case situations.

OBJECTIVES: Dizziness, vertigo, and unsteadiness are common complaints of patients who present to primary care providers. These patients often are referred to otology for assessment and management. Unfortunately, there are a small number of specialists to manage these patients. However, there are several dizziness disorders that can be successfully managed by primary care providers if the disorder is properly identified. To assist in the identification of several of the most common dizziness disorders, we developed the dizziness symptom profile (DSP). The DSP is a self-report questionnaire designed to generate one or more differential diagnoses that can be combined with the patient's case history and physical examination. DESIGN: This report describes three investigations. Investigations 1 and 2 (i.e., exploratory and confirmatory investigations, N = 514) describe the development of the DSP. Investigation 3 (N = 195) is a validation study that describes the level of agreement between the DSP completed by the patient, and, the differential diagnosis of the otologist. RESULTS: The final version of the DSP consists of 31 items. Preliminary findings suggest that the DSP is in agreement with the differential diagnoses of ear specialists for Meniere's disease (100% agreement), vestibular migraine (95% agreement), and benign paroxysmal positional vertigo (82% agreement). CONCLUSIONS: Early results suggest that DSP may be useful in the creation of differential diagnoses for dizzy patients that can be evaluated and managed locally. This has the potential to reduce the burden on primary care providers and reduce delays in the diagnosis of common dizziness and vertigo disorders.

OBJECTIVE: To increase otolaryngology resident experience with drilling and dissection of the internal auditory canal (IAC) via a translabyrinthine approach. STUDY DESIGN: Pilot study involving temporal bone education and drilling with completion of pre- and post-drilling surveys. METHODS: Participants observed an educational presentation on IAC anatomy and drilling, followed by manipulation of IAC nerves using a prosected cadaveric temporal bone. Participants then drilled the IAC and identified nerves using temporal bones with previously drilled mastoidectomies and labyrinthectomies. Pre- and post-drilling 5-point Likert-based surveys were completed. RESULTS: 7 participants were included in this study ranging in experience from PGY1 through PGY 5. The median number of times the IAC had been drilled previously was 0. Participants reported statistically significantly improved familiarity with the translabyrinthine approach after the session with median scores increasing from 2 to 3 (p=0.02), and a near-significant increase in familiarity with IAC anatomy with median scores increasing from 3 to 4 (p=0.06). Prior to the session, 71% of participants either disagreed or strongly disagreed that they had an idea of what the procedure would be like in a real operating room, whereas after the session 0% reported disagreement. 100% of participants were very satisfied with the overall experience. CONCLUSIONS: An educational session and temporal bone drilling experience using prosected bones significantly increased the reported familiarity with the translabyrinthine approach. Experiences such as this may enhance resident exposure to advanced lateral skull base approaches in a safe environment, and increase comprehension of the complex anatomic relationships of the IAC.

PURPOSE: To present the surgical technique and clinical outcomes of a novel modification to conventional meatoplasty. MATERIALS AND METHODS: All consecutive patients undergoing canal wall down tympanomastoidectomy incorporating the one-cut meatoplasty technique between January 2009 and February 2013 were evaluated. Primary outcome measures included meatal stenosis requiring revision surgery, frequency of drainage beyond 2months postoperatively and results of a composite patient questionnaire incorporating the Chronic Ear Survey. RESULTS: Twenty-eight of 36 (78%) eligible patients completed a questionnaire and were included. All ears underwent canal wall down tympanomastoidectomy utilizing the one-cut meatoplasty technique. At a mean follow-up of 38.0months, the average Chronic Ear Survey score was 78.6±2.6 points. There was only one case of postoperative meatal stenosis. Intermittent otorrhea developed in 14.3% of cases but was remedied by conservative measures including in-office cleaning, ototopical therapy and water precautions. Eighty-nine percent of patients denied any self-consciousness about the aesthetic appearance of the ear. CONCLUSIONS: The one-cut meatoplasty is an effective alternative to traditional techniques that is simple to perform. The results of the Chronic Ear Survey indicate that the one-cut meatoplasty supports a stable and healthy, open cavity with functional results that compare favorably to other series evaluating canal wall down tympanomastoidectomy with traditional meatoplasty. Additionally, patients report high satisfaction with the appearance of their ear, and all hearing aid users could continue to utilize a hearing aid without feedback, pain, or other difficulties related to poor fitting.

OBJECTIVE: This study aimed to better identify factors associated with recurrence of squamous cell carcinoma (SCC) involving the temporal bone. METHODS: A retrospective study was conducted at a tertiary hospital. Sixty patients who were diagnosed over a 10-year period with SCC involving the temporal bone and underwent surgical resection were analyzed. All patients were staged based on the University of Pittsburgh staging system. Demographic, intraoperative, and pathologic data were analyzed with respect to recurrence. RESULTS: Thirteen (21.7%) patients were T1, 8 (13.3%) T2, 7 (11.7%) T3, and 32 (53.3%) T4. Eighteen patients (30.0%) recurred in the study period. The mean time to recurrence was 5.8 months. Tumors originating in the skin overlying the parotid gland and the external auditory canal had higher recurrence rates than those from the auricle/postauricular skin and temporal bone (P = .05). Direct parotid and perineural spread accounted for 15.0% of all routes of temporal invasion but resulted in 22.2% of all recurrences (P = .04). Increased N stage was statistically associated with increased risk of recurrence (P = .01). Cervical, as compared to perifacial and parotid, lymph node involvement was associated with increased risk of recurrence (odds ratio = 6.91; 95% confidence interval, 1.11-42.87). CONCLUSION: We have identified multiple factors that are associated with increased recurrence of SCC involving the temporal bone.

Meningiomas are the most common extra-axial intracranial neoplasm and frequently develop in the parasagittal region. Rarely, meningiomas may involve the middle ear and mastoid, resulting from contiguous spread of adjacent intracranial tumor, or less commonly as an isolated primary tumor of the middle ear. Patients with primary middle ear meningiomas (MEMs) often present with non-specific otologic complaints including hearing loss, otorrhea and otalgia thereby mimicking common chronic otitis media, while secondary lesions more frequently manifest sensorineural hearing loss, cranial neuropathy and other neurologic symptoms from the associated intracranial component. The radiological appearance of MEMs often overlaps with other tumors of the temporal bone. Therefore, a correct diagnosis cannot always be made prior to surgical biopsy. While gross total resection with preservation of existing neurological function is possible with smaller lesions, complete tumor removal may be extremely morbid with more extensive or adherent MEMs. In such cases, aggressive subtotal resection with close radiologic follow-up should be considered. Given the rarity of the studied condition, the literature addressing MEMs is sparse. The current study reviews ten additional cases of MEMs, highlighting the clinicopathologic and radiological features that distinguish meningiomas from other middle ear and mastoid pathology.

OBJECTIVE: To demonstrate the added value of magnetic resonance imaging (MRI) over computed tomography (CT) during adult cochlear implant evaluation. PATIENTS: Two adult patients are discussed in whom MRI studies diagnosed bilateral vestibular schwannomas during cochlear implant candidacy evaluation. INTERVENTIONS: Temporal bone CT and MRI. MAIN OUTCOME MEASURE: Diagnosis of NF2. RESULTS: Two adult patients, ages 67 and 68 years, were evaluated for cochlear implant candidacy. Both patients experienced slowly progressive, bilateral hearing loss without complaints of vertigo, and neither patient had a family history of hearing loss or neurogenic tumors. Both patients had near-symmetric pure tone thresholds on audiometric testing. An MRI and a CT scan were performed on both patients, and bilateral vestibular schwannomas were identified on MRI. CONCLUSIONS: Though MRI is not routinely utilized in adult cochlear implant evaluation, it may be of greater clinical value than CT in the setting of adult-onset hearing loss. MRI allows for sensitive evaluation of cochlear patency and architecture, and cochlear nerve status. As demonstrated in the two index cases, MRI also provides the added benefit of evaluating for causes of retrocochlear hearing loss. These two patients would have likely experienced a significant delay in diagnosis of NF2 without preoperative MRI, particularly given the limitations of scanning following CI magnet placement.

OBJECTIVE: To assess speech recognition and hearing preservation (HP) outcomes with the Advanced Bionics Mid-Scala and SlimJ electrodes. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary referral center. PATIENTS: A total of 237 adult patients implanted between 2013 and 2020 (Mid-Scala, n = 136; SlimJ, n = 101). MAIN OUTCOME MEASURES: Consonant-nucleus-consonant (CNC) and AzBio (Arizona Biomedical) scores at 6 and 12 months; postoperative HP, defined as low-frequency pure-tone average ≤ 80 dB HL; scalar position. RESULTS: Mean CNC scores did not significantly differ between Mid-Scala and SlimJ recipients at 6 (45.8% versus 46.0%, p = 0.962) and 12 (51.9% versus 48.8%, p = 0.363) months. Similarly, mean AzBio in quiet scores were equivalent for both groups at 6 (55.1% versus 59.2%, p = 0.334) and 12 (60.6% versus 62.3%, p = 0.684) months. HP rates were significantly higher with the SlimJ (48.4%) than the Mid-Scala (30.8%; p = 0.033). Scalar translocations were 34.8 and 16.1% for the Mid-Scala and SlimJ groups, respectively ( p = 0.019). Ears with postoperative HP had significantly fewer scalar translocations (16.7% versus 37.2%, p = 0.048), and postoperative HP was associated with higher AzBio in noise scores at the most recent follow-up interval (38.7% versus 25.1%, p = 0.042). CNC, AzBio in quiet and noise, low-frequency pure-tone average shifts, and PTA at 6 and 12 months were not significantly different between patients with scala tympani insertions of the SlimJ versus the Mid-Scala ( p > 0.05). CONCLUSIONS: Compared with the Mid-Scala, the lateral wall electrode has superior HP rates and fewer scalar translocations, whereas speech recognition scores are equivalent between both electrode arrays. These findings can help providers with electrode selection and patient counseling.

OBJECTIVES: Evaluate potential effects of calcium channel blockers (CCB) and bisphosphonates (BP) on residual hearing following cochlear implantation. METHODS: Medications of 303 adult hearing preservation (HP) candidates (low frequency pure tone average [LFPTA] of 125, 250, and 500â Hz ≤80â dB HL) were reviewed. Postimplantation LFPTA of patients taking CCBs and BPs were compared to controls matched by age and preimplantation LFPTA. RESULTS: Twenty-six HP candidates were taking a CCB (N = 14) or bisphosphonate (N = 12) at implantation. Median follow-up was 1.37 years (range 0.22-4.64y). Among subjects with initial HP, 29% (N = 2 of 7) CCB users compared to 50% (N = 2 of 4) controls subsequently lost residual hearing 3-6 months later (OR = 0.40, 95% CI = 0.04-4.32, p = 0.58). None of the four BP patients with initial HP experienced delayed loss compared to 50% (N = 2 of 4) controls with initial HP (OR = 0.00, 95% CI = 0.00-1.95, P = 0.43). Two CCB and one BP patients improved to a LFPTA <80 dB HL following initial unaided thresholds that suggested loss of residual hearing. DISCUSSION: There were no significant differences in the odds of delayed loss of residual hearing with CCBs or BPs. CONCLUSION: Further investigation into potential otoprotective adjuvants for maintaining residual hearing following initial successful hearing preservation is warranted, with larger cohorts and additional CCB/BP agents.
RESUMO
OBJECTIVES: Social media has enabled discussion of relevant topics within otolaryngology. With increasing academic discourse occurring on virtual platforms, it is important to examine who is influencing these discussions. This study thus aims to: (1) identify the top Twitter influencers in otolaryngology and (2) assess the relationship between Twitter influence and academic impact. STUDY DESIGN: Cross-sectional analysis. SETTING: Twitter. METHODS: The Right Relevance program was used to identify and rank the top 75 Twitter influencers, excluding organizations, according to the search terms "otolaryngology," "head and neck surgery," "ear nose throat," "rhinology," "head and neck," "laryngology," "facial plastics," and "otology." Demographic data and h-index were collected for each influencer. Correlational analyzes were performed to assess the relationships between Twitter rank and geographic location, sex, subspecialty, and h-index. RESULTS: The majority of the top 75 influencers were otolaryngologists (87%), female (68%), and located in the United States (61%). General otolaryngology (n = 20, 31%) was more well-represented than any individual subspecialty including facial plastics (n = 10, 15%), rhinology (n = 10, 15%), and neurotology (n = 9, 14%). There was a significant relationship between Twitter rank and h-index (Spearman ρ value of -0.32; 95% confidence interval: -0.51 to -0.01; P = .006). Twitter rank was not significantly correlated with subspecialty, sex, or geographic location (P > .05). CONCLUSION: The majority of Twitter influencers within otolaryngology were otolaryngologists, female, and located in the United States. Social media influence is positively associated with academic impact among otolaryngologists.

Introduction The middle fossa craniotomy (MFCs) is commonly utilized for spontaneous cerebrospinal fluid (CSF) leaks, encephaloceles, and superior semicircular canal dehiscence (SSCD). This study compares postoperative outcomes of MFCs with and without LD use. Methods A retrospective cohort study of adults over the age of 18 years presenting for the repair of nonneoplastic CSF leak, encephalocele, or SSCD via MFC from 2009 to 2021 was conducted. The main exposure of interest was the placement of an LD. The primary outcome was the presence of postoperative complications (acute/delayed neurologic deficit, meningitis, intracranial hemorrhage, and stroke). Secondary outcomes included operating room (OR) time, length of stay, recurrence, and need for reoperation. Results In total, 172 patients were included, 96 of whom received an LD and 76 who did not. Patients not receiving an LD were more likely to receive intraoperative mannitol ( n = 24, 31.6% vs. n = 16, 16.7%, p = 0.02). On univariate logistic regression, LD placement did not influence overall postoperative complications (OR: 0.38, 95% confidence interval [CI]: 0.05-2.02, p = 0.28), CSF leak recurrence (OR: 0.75, 95% CI: 0.25-2.29, p = 0.61), or need for reoperation (OR: 1.47, 95% CI: 0.48-4.96, p = 0.51). While OR time was shorter for patients not receiving LD (349 ± 71 vs. 372 ± 85 minutes), this difference was not statistically significant ( p = 0.07). Conclusion No difference in postoperative outcomes was observed in patients who had an intraoperative LD placed compared to those without LD. Operative times were increased in the LD cohort, but this difference was not statistically significant. Given the similar outcomes, we conclude that LD is not necessary to facilitate safe MCF for nonneoplastic skull base pathologies.
RESUMO
OBJECTIVE: To report speech recognition outcomes and processor use based on timing of cochlear implant (CI) activation. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary referral center. PATIENTS: A total of 604 adult CI recipients from October 2011 to March 2022, stratified by timing of CI activation (group 1: ≤10 d, n = 47; group 2: >10 d, n = 557). MAIN OUTCOME MEASURES: Average daily processor use; Consonant-Nucleus-Consonant (CNC) and Arizona Biomedical (AzBio) in quiet at 1-, 3-, 6-, and 12-month visits; time to peak performance. RESULTS: The groups did not differ in sex ( p = 0.887), age at CI ( p = 0.109), preoperative CNC ( p = 0.070), or preoperative AzBio in quiet ( p = 0.113). Group 1 had higher median daily processor use than group 2 at the 1-month visit (12.3 versus 10.7 h/d, p = 0.017), with no significant differences at 3, 6, and 12 months. The early activation group had superior median CNC performance at 3 months (56% versus 46%, p = 0.007) and 12 months (60% versus 52%, p = 0.044). Similarly, the early activation group had superior median AzBio in quiet performance at 3 months (72% versus 59%, p = 0.008) and 12 months (75% versus 68%, p = 0.049). Both groups were equivalent in time to peak performance for CNC and AzBio. Earlier CI activation was significantly correlated with higher average daily processor use at all follow-up intervals. CONCLUSION: CI activation within 10 days of surgery is associated with increased early device usage and superior speech recognition at both early and late follow-up visits. Timing of activation and device usage are modifiable factors that can help optimize postoperative outcomes in the CI population.

PURPOSE: The ocular vestibular evoked myogenic potential (oVEMP) represents the sound-induced activation of extraocular muscles and is believed to originate from the utricle and superior vestibular nerve. Isolated unilateral oVEMP abnormalities with otherwise normal balance function test (BFT) results have not yet been characterized in a large patient series, and their clinical significance remains unclear. MATERIALS AND METHODS: Retrospective review of adult patients with vestibular complaints at a tertiary academic neurotologic referral center was performed. Patients with isolated unilateral oVEMP abnormalities were identified. The prevalence of vestibular symptoms and results of the Dizziness Handicap Inventory (DHI) and Hospital Anxiety and Depression Scale (HADS) were compared between these patients and those with normal BFT results. RESULTS: Thirty-one adult patients with isolated unilateral oVEMP abnormalities were identified (71% female, mean age 48 ± 14 years). Presenting complaints included vertigo in 53%, non-vertiginous dizziness in 68%, postural instability in 52%, and swaying/rocking sensation in 13%. Significant differences were observed in the percentage of patients with postural instability (p=0.046) and swaying/rocking sensation (p=0.04) when comparing the abnormal oVEMP group to patients with a normal BFT battery. No differences were observed when comparing other symptoms, age, gender, diagnoses, and DHI/HADS scores between groups. CONCLUSION: This is the largest series to date reporting on patients with isolated unilateral oVEMP abnormalities. Our results suggest this population may demonstrate an increased prevalence of postural instability and swaying/rocking sensation. Other measures of postural stability may further characterize the vestibular impairments associated with isolated unilateral utricular dysfunction.

OBJECTIVE: To evaluate safety of monopolar electrosurgery (MES) in patients with cochlear implants (CIs) by reporting outcomes of a series of patients who underwent MES after CI. STUDY DESIGN: Retrospective case series. SETTING: Tertiary referral center. PATIENTS: Patients with indwelling CI subsequently undergoing surgery with operative note specifically detailing MES use. MAIN OUTCOME MEASURES: Adverse outcomes in post-operative audiology/otolaryngology documentation; speech recognition scores. RESULTS: Thirty-five patients (10 with bilateral CI) experienced 63 unique MES exposure events, 85.7% below and 14.3% above the clavicle. No adverse events or decreased performance due to MES use were reported for any patient. Pre- and immediate postoperative speech recognition scores were not significantly different for patients using either consonant-nucleus-consonant (CNC; n = 23, 68%-66%, p = 0.80) or AzBio (n = 15, 82%-88%, p = 0.60). For individual CNC performance, 21 (91%) patients demonstrated stability, 1 improved >15%, and 1 declined >15%, although this patient had become a non-user due to magnet issues and, after resolution of these issues, exceeded baseline pre-operative score. For individual AzBio performance, 12 (80%) patients demonstrated stability, 3 improved >15%, and none declined >15%. CONCLUSIONS: No adverse events resulted from MES use in CI patients. Given the increased prevalence and expansion of indications for CIs, and widespread utility of MES, we suggest clarification and improved guidance from device manufacturers regarding safety and use of MES for patients with these devices. We hope that data regarding electrosurgery exposure events will better inform clinician decision-making with regards to relative benefits and risks for MES use for CI patients.

TITLE: Facial Paralysis in Skull Base Osteomyelitis - Comparison of Surgical and Nonsurgical Management. OBJECTIVE: To compare outcomes of surgical and nonsurgical management in cases of facial paresis secondary to skull base osteomyelitis. METHODS: A 14 patients presenting with skull base osteomyelitis complicated by facial nerve paresis at a single tertiary referral center from 2009 to 2019 were retrospectively reviewed. Patients were treated with medical therapy with or without surgical intervention, consisting of mastoidectomy and debridement with or without facial nerve decompression. House-Brackmann (HB) Grade was the main outcome measure. RESULTS: A 14 patients (average age 68 years, range 58-82 years, 71% male) were analyzed, with 5 undergoing facial nerve decompression (36%), 5 undergoing mastoidectomy without facial nerve decompression (36%), and 4 undergoing medical management alone (28%). Of the 4 patients who underwent medical therapy alone, none experienced significant improvement in facial function. Of the 5 patients who underwent facial nerve decompression, 3 patients experienced improved facial function. Of the 5 patients who underwent mastoidectomy without decompression, 4 experienced improved facial function. There was no clear link between the severity of infection and the severity of facial paresis. When comparing HB score changes before and after treatment across groups, there was no statistically significant difference seen (p = 0.47). CONCLUSIONS: Mastoidectomy and debridement with or without facial nerve decompression may improve facial nerve outcomes when compared to isolated medical management, although differences were not of statistical significance. The best facial nerve recoveries occurred in patients undergoing surgery within 14 days of the onset of paralysis. LEVEL OF EVIDENCE: 4 - Case Series Laryngoscope, 133:179-183, 2023.

OBJECTIVE: To quantify the roles and relationships between age at implantation, duration of deafness (DoD), and daily processor use via data logging on speech recognition outcomes for postlingually deafened adults with cochlear implants. STUDY DESIGN: Retrospective case review. SETTING: Cochlear implant (CI) program at a tertiary medical center. PATIENTS: Six-hundred fourteen postlingually deafened adult ears with CIs (mean age, 63 yr; 44% female) were included. MAIN OUTCOME MEASURES: A stepwise multiple regression analysis was completed to investigate the combined effects of age, DoD, and daily processor use on CI-aided speech recognition (Consonant-Nucleus-Consonant monosyllables and AzBio sentences). RESULTS: Results indicated that only daily processor use was significantly related to Consonant-Nucleus-Consonant word scores ( R2 = 0.194, p < 0.001) and AzBio in quiet scores ( R2 = 0.198, p < 0.001), whereas neither age nor DoD was significantly related. In addition, there was no significant relationship between daily processor use, age at implantation, or DoD and AzBio sentences in noise ( R2 = 0.026, p = 0.005). CONCLUSIONS: Considering the clinical factors of age at implantation, DoD, and daily processor use, only daily processor use significantly predicted the ~20% of variance in postoperative outcomes (CI-aided speech recognition) accounted for by these clinical factors.

OBJECTIVE: To develop a machine learning-based referral guideline for patients undergoing cochlear implant candidacy evaluation (CICE) and to compare with the widely used 60/60 guideline. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary referral center. PATIENTS: 772 adults undergoing CICE from 2015 to 2020. INTERVENTIONS: Variables included demographics, unaided thresholds, and word recognition score. A random forest classification model was trained on patients undergoing CICE, and bootstrap cross-validation was used to assess the modeling approach's performance. MAIN OUTCOME MEASURES: The machine learning-based referral tool was evaluated against the 60/60 guideline based on ability to identify CI candidates under traditional and expanded criteria. RESULTS: Of 587 patients with complete data, 563 (96%) met candidacy at our center, and the 60/60 guideline identified 512 (87%) patients. In the random forest model, word recognition score; thresholds at 3000, 2000, and 125; and age at CICE had the largest impact on candidacy (mean decrease in Gini coefficient, 2.83, 1.60, 1.20, 1.17, and 1.16, respectively). The 60/60 guideline had a sensitivity of 0.91, a specificity of 0.42, and an accuracy of 0.89 (95% confidence interval, 0.86-0.91). The random forest model obtained higher sensitivity (0.96), specificity (1.00), and accuracy (0.96; 95% confidence interval, 0.95-0.98). Across 1,000 bootstrapped iterations, the model yielded a median sensitivity of 0.92 (interquartile range [IQR], 0.85-0.98), specificity of 1.00 (IQR, 0.88-1.00), accuracy of 0.93 (IQR, 0.85-0.97), and area under the curve of 0.96 (IQR, 0.93-0.98). CONCLUSIONS: A novel machine learning-based screening model is highly sensitive, specific, and accurate in predicting CI candidacy. Bootstrapping confirmed that this approach is potentially generalizable with consistent results.

OBJECTIVE: To characterize the incidence of sigmoid sinus occlusion (SSO) following translabyrinthine (TL) surgery for posterior fossa tumor resection and determine the association with cerebrospinal fluid (CSF) leak. STUDY DESIGN: Retrospective case series. SETTING: Tertiary referral center. METHODS: Patients undergoing TL surgery for vestibular schwannoma from 2012 to 2020 were included. Demographic data, medical history, preoperative tumor length and volume, and postoperative complications including CSF leak were recorded. Neuroradiology review of postoperative magnetic resonance imaging was used to determine the presence or absence of flow through the sigmoid sinus. RESULTS: Of 205 patients undergoing TL, 21 (10.2%) experienced CSF leak postoperatively. Overall 56 (27%) demonstrated SSO on immediate postoperative magnetic resonance imaging. CSF leaks were more likely in those with SSO (19.6%) than those without SSO (6.7%; odds ratio, 3.54 [95% CI, 1.25-10.17]). Tumor volume and body mass index were not significantly associated with CSF leak. In total, 105 (51%) patients had some degree of sigmoid sinus thrombosis, but nonocclusive thrombosis was not associated with CSF leak. CONCLUSION: SSO after TL approaches is common and appears to be significantly associated with postoperative CSF leak development. Minimizing manipulation of the sigmoid sinus during TL surgery and compression after surgery may have a role in preventing CSF leak.

OBJECTIVE: To report our experience for adults undergoing cochlear implantation (CI) for single-sided deafness (SSD). METHODS: This is a retrospective case series for adults with SSD who underwent CI between January 2013 and May 2021 at our institution. CNC and AzBio speech recognition scores, Tinnitus Handicap Inventory (THI), Speech, Spatial, and Qualities of Hearing Scale (SSQ12), datalogging, and the Cochlear Implant Quality of Life (CIQOL)-10 Global measure were utilized. RESULTS: Sixty-six adults underwent CI for SSD (median 51.3 years, range 20.0-74.3 years), and 57 (86.4%) remained device users at last follow-up. Compared to pre-operative performance, device users demonstrated significant improvement in speech recognition scores and achieved peak performance at six months post-activation for CNC (8.0% increased to 45.6%, p < 0.0001) and AzBio in quiet (12.2% increased to 59.5%, p < 0.0001). THI was decreased at 6 months post-implantation (58.1-14.6, p < 0.0001), with 77% of patients reporting improved or resolved tinnitus. Patients demonstrated improved SSQ12 scores as well as the disease-specific CIQOL-10 Global questionnaire. Duration of deafness was not associated with significant differences in speech recognition performance. Average daily wear time was positively associated with CNC and AzBio scores as well as post-operative CIQOL-10 scores. CONCLUSIONS: Herein we present the largest cohort of adult CI recipients with SSD with data on speech recognition scores, tinnitus measures, and SSQ12. Novel insights regarding the correlation of datalogging, duration of deafness, and CI-specific quality of life (CIQOL-10) metrics are discussed. Data continue to support CI as an efficacious treatment option for SSD. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2362-2370, 2023.

OBJECTIVE: Compare incidence of sigmoid sinus wall abnormalities (SSWAs) and other radiographic abnormalities in patients with pulsatile tinnitus (PT) versus controls. STUDY DESIGN: Retrospective case-control. SETTING: Tertiary referral center. PATIENTS: Adults with PT and high-resolution computed tomography imaging were compared with adults undergoing cochlear implant workup including high-resolution computed tomography imaging. MAIN OUTCOME MEASURES: Incidence of SSWA in PT cohort (n = 141) compared with control (n = 149, n = 298 ears). Secondary outcome measures included differences in demographics and in other radiographic abnormalities between cohorts. RESULTS: Patients with PT had a higher incidence of SSWA (34% versus 9%, p < 0.001) and superior canal dehiscence (23% versus 12%, p = 0.017) than controls. Spearman product component correlations demonstrated that ipsilateral PT was weakly associated with SSWA ( r = 0.354, p < 0.001). When SSWA was present in the PT cohort (n = 48 patients, n = 59 ears), in 31 cases (64.6%), the SSWA correlated with PT laterality (e.g., left SSWA, left PT); in 12 (25.0%), SSWA partially correlated with PT laterality (e.g., bilateral SSWA, right PT); and in 5 (10.4%), the SSWA did not correlate with PT laterality (e.g., right SSWA, left PT). CONCLUSIONS: For our patients with both PT and SSWA, the SSWA is likely a contributing factor in approximately 65% of cases. For a third of patients with PT and concomitant SSWA, the association between the two is either not causative or not solely causative. Surgeons counseling patients with PT and SSWA may be optimistic overall regarding sigmoid resurfacing procedures but must appreciate the possibility of treatment failure, likely because of untreated comorbid conditions.
