Abstract
OBJECTIVE To investigate the safety and feasibility of precise delivery of a long-acting gel formulation containing 6% dexamethasone (SPT-2101) to the round window membrane for the treatment of Menière's disease. STUDY DESIGN Prospective, unblinded, cohort study. SETTING Tertiary care neurotology clinic. PATIENTS Adults 18 to 85 years with a diagnosis of unilateral definite Menière's disease per Barany society criteria. INTERVENTIONS A single injection of a long-acting gel formulation under direct visualization into the round window niche. MAIN OUTCOME MEASURES Procedure success rate, adverse events, and vertigo control. Vertigo control was measured with definitive vertigo days (DVDs), defined as any day with a vertigo attack lasting 20 minutes or longer. RESULTS Ten subjects with unilateral Menière's disease were enrolled. Precise placement of SPT-2101 at the round window was achieved in all subjects with in-office microendoscopy. Adverse events included one tympanic membrane perforation, which healed spontaneously after the study, and two instances of otitis media, which resolved with antibiotics. The average number of DVDs was 7.6 during the baseline month, decreasing to 3.3 by month 1, 3.7 by month 2, and 1.9 by month 3. Seventy percent of subjects had zero DVDs during the third month after treatment. CONCLUSIONS SPT-2101 delivery to the round window is safe and feasible, and controlled trials are warranted to formally assess efficacy.

Abstract
OBJECTIVE Determine levels of catastrophizing in patients with vestibular disorders and prospectively evaluate their relationship with patient-reported outcome measures. STUDY DESIGN Prospective cohort study. SETTING Tertiary care neurotology vestibular disorders clinic. PATIENTS Adult patients with various vestibular disorders. INTERVENTIONS Patients were given the Dizziness Handicap Inventory (DHI) and the Dizziness Catastrophizing Scale (DCS) at a baseline visit and follow-up visit after treatment. MAIN OUTCOME MEASURES Correlation studies were used to determine the relationships between DHI and DCS. Multivariable linear regression was performed to determine the relationship between DCS and DHI change with treatment, accounting for demographic variables. RESULTS Forty-six subjects completed both the DHI and the DCS before and after treatment. Patients with higher baseline DCS scores had higher baseline DHI scores ( p < 0.001). There was a significant improvement in both DHI score ( p < 0.001) and DCS ( p < 0.001) at follow-up. Patients who had reduction in DCS scores during were more likely to show reduction in DHI scores ( p < 0.001). A subset of patients had a mindfulness-based stress reduction program included in their treatment. These patients had a greater reduction in both DCS and DHI scores at follow-up compared with those who received other treatments. CONCLUSIONS Catastrophizing is associated with higher pretreatment DHI scores and worse treatment outcomes. Addressing dizziness catastrophizing may help improve vestibular outcomes.

Abstract
OBJECTIVE To establish a case series where loss of magnetic resonance fluid signal intensity in the posterior semicircular canal (SCC) corresponded with a functional deficit on clinical and video head impulse testing, and most likely a result of canal fibrosis or obstruction. PATIENTS Three patients with an magnetic resonance imaging (MRI) showing loss of T2-weighted signal intensity in their posterior SCC corresponding to a vestibular weakness in that canal. INTERVENTIONS All patients underwent a comprehensive neuro-otologic examination. Vestibulo-ocular reflex was evaluated using clinical head impulse testing (cHIT) and quantified with video head impulse testing. MRI for all patients was obtained using clinical protocols for gadolinium-enhanced MRI of the internal auditory canal on 1.5 or 3 T scanners, which all included high-resolution, heavily T2-weighted imaging of the membranous labyrinth. MAIN OUTCOME MEASURE Correlation of MRI findings with vestibular weakness in the corresponding posterior SCC. RESULTS Subject 1 showed abnormal vHIT in the left lateral and left posterior SCCs. MRI showed loss of T2 signal intensity of the entire left posterior SCC as well as in the posterior limb of the superior SCC. Subject 2 showed isolated loss of function (cHIT) and low gain with catch-up saccade (vHIT) of the left posterior SCC. MRI showed loss of T2 signal intensity of the superior portion of the left posterior SCC, as well as in the posterior limb of the superior SCC. Subject 3 showed catch-up saccades of the left posterior SCC on cHIT and vHIT and loss of T2 signal intensity of the entire left posterior SCC and partial loss of bilateral lateral SCC on MRI. CONCLUSIONS In this case series, loss of posterior SCC function correlated with vestibular function testing and high-resolution, T2-weighted MRI findings, perhaps related to fibrosis of the posterior SCC.

Abstract
OBJECTIVES Evaluate the measurement properties of the Dizziness Handicap Inventory (DHI) using item response theory in patients diagnosed with vestibular migraine (VM) and Meniere's disease (MD). DESIGN One hundred twenty-five patients diagnosed with VM and 169 patients diagnosed with MD by a vestibular neurotologist according to the Bárány Society criteria in two tertiary multidisciplinary vestibular clinics and who completed the DHI at their initial visit, were included in the study. The DHI (total score and individual items) was analyzed using the Rasch Rating Scale model for patients in each subgroup, VM and MD, and as a whole group. The following categories were assessed: rating-scale structure, unidimensionality, item and person fit, item difficulty hierarchy, person-item match, and separation index, standard error of measurement, and minimal detectable change (MDC). RESULTS Patients were predominantly female (80% of the VM subgroup and 68% of the MD subgroup) with a mean age of 49.9 ± 16.5 years and 54.1 ± 14.2 years, respectively. The mean total DHI score for the VM group was 51.9 ± 22.3 and for the MD group was 48.5 ± 26.6 ( p > 0.05). While neither all items nor the separate constructs met all criteria for unidimensionality (i.e., items measuring a single construct), post hoc analysis showed that the all-item analysis supported a single construct. All analyses met the criterion for showing a sound rating scale and acceptable Cronbach's alpha (≥0.69). The all-item analysis showed the most precision, separating the samples into three to four significant strata. The separate-construct analyses (physical, emotional, and functional) showed the least precision, separated the samples into less than three significant strata. Regarding MDC, the MDC remained consistent across the analyses of the different samples; approximately 18 points for the full analyses and approximately 10 points for the separate construct (physical, emotional, and functional). CONCLUSIONS Our evaluation of the DHI using item response theory shows that the instrument is psychometrically sound and reliable. The all-item instrument fulfills criteria for essential unidimensionality but does seem to measure multiple latent constructs in patients with VM and MD, which has been reported in other balance and mobility instruments. The current subscales did not show acceptable psychometrics, which is in line with multiple recent studies favoring the use of the total score. The study also shows that the DHI is adaptable to episodic recurrent vestibulopathies. The total score shows better precision and separation of subjects in up to four strata compared to the separate construct that separate subjects into less than three strata. The measurement error smallest detectable change was found in our analysis to be 18 points, which means any change in the DHI of less than 18 points is not likely to be clinically significant. The minimal clinically important difference remains indeterminate.

Abstract
OBJECTIVE Investigate the relationship between Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI) scores and daily dizziness symptoms. STUDY DESIGN Prospective cohort analysis of 52 patients with vestibular migraine (VM). SETTING Tertiary referral center. PATIENTS Fifty-two patients diagnosed with VM or probable VM according to Barany Society criteria. INTERVENTIONS Subjects reported their dizzy symptoms (on a scale of 0 [no symptoms], 1 [mild], 2 [moderate], and 3 [severe]) every day for 1 month via automated text messaging linked to a cloud-based research database. Subjects completed VM-PATHI and Dizziness Handicap Inventory (DHI) scores at the end of the month. We examined the correlation between a composite of daily dizziness scores with VM-PATHI and DHI scores through linear regression and correlation analysis. MAIN OUTCOME MEASURES Pearson correlation coefficient, R2 value. RESULTS VM-PATHI showed a moderate correlation with daily dizziness symptoms (correlation coefficient, 0.51). DHI showed a lower correlation with daily dizziness (correlation coefficient, 0.38). VM-PATHI score was a strong predictor of daily dizziness with univariate linear regression ( R2 = 0.26, p = 0.001). In a multiple linear regression model with age, history of anxiety and/or depression, and VM-PATHI, the VM-PATHI score was the only statistically significant predictor of daily dizziness ( p < 0.001). CONCLUSIONS Daily dizziness symptoms are better correlated with VM-PATHI score than the DHI, providing further validation of VM-PATHI as a disease-specific outcome measure for patients with VM.

Abstract
PURPOSE The aim of this study was to review current literature regarding the epidemiology of vestibular migraine (VM), patient presentation, pathogenesis, and treatment. RECENT FINDINGS VM is becoming an increasingly recognized condition in the United States, currently affecting 2.7% of people. Patients may experience vestibular symptoms, such as vertigo and imbalance, with or without other migrainous symptoms. Recent evidence has also shown that patients with VM are at higher risk for cochlear dysfunction, such as sudden deafness, sensorineural hearing loss, and tinnitus. The heritability and genetics are not well understood, and the pathogenesis may involve calcitonin gene-related peptide, which is also implicated in migraine headaches. A disease-specific patient reported outcome measure, the Vestibular Migraine Patient Assessment Tool and Handicap Inventory, was recently developed and validated. A limited number of controlled trials have assessed various therapies for VM, including triptans and beta-blockers. More data are needed to understand whether or not currently available migraine treatments are effective for VM. SUMMARY VM is a common etiology of vertigo and dizziness, presenting with a characteristic spectrum of symptoms. Early data suggest that migraine treatments may be helpful in some cases.

Abstract
OBJECTIVE To assess changes in cognitive function in vestibular migraine patients undergoing treatment. STUDY DESIGN Prospective cohort. SETTING Single-institution tertiary-care center. PATIENTS Thirty-four patients with vestibular migraine were included in the study. Average age at diagnosis was 47.9 years. A majority of patients (91.2%) were female. INTERVENTIONS Vestibular therapies included pharmacologic treatment (67.6%), mindfulness-based stress reduction (58.8%), vestibular physical therapy (20.6%), and lifestyle changes only (2.9%). MAIN OUTCOME MEASURES Pretreatment and posttreatment questionnaires were collected including the Cognitive Failures Questionnaire (CFQ), Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI), and Dizziness Handicap Inventory. RESULTS Median time between pretreatment and posttreatment questionnaire was 4.4 months (range, 2.8-15.6. mo). CFQ scores decreased in subjects who responded to treatment, as defined by those with a positive change in VM-PATHI score (average decrease, 6.5; p = 0.03). CFQ scores did not improve in subjects who had no improvement in their vestibular condition, as defined by no change or an increase in VM-PATHI score (average increase, 2.0; p = 0.53). Univariate linear regression showed that VM-PATHI score change was highly predictive of CFQ change ( p < 0.01, r2 = 0.36). Multivariate regression demonstrated that the VM-PATHI ( p = 0.03) and not the Dizziness Handicap Inventory ( p = 0.10) predicted changes in CFQ score. CONCLUSIONS Self-reported cognitive dysfunction improves with successful treatment of vestibular migraine.

Abstract
Objective Vestibular migraine (VM) is a diagnostic challenge. Visually enhanced vestibulo-ocular reflex (VVOR) gain, a measure of the visual-vestibular interaction, has been proposed as a tool for diagnosing VM. This study seeks to evaluate VVOR gain's diagnostic capability to predict VM and to compare the phenotypes of vestibular patients with elevated versus normal/low VVOR gain. Methods A retrospective review of consecutive adult patients at a dizziness clinic from October 2016 and December 2020 was conducted. VVOR gain's diagnostic performance was assessed with the area under the receiver operating characteristic (AUROC) analysis. Demographic factors and clinical presentations were compared between vestibular patients with elevated versus normal/low VVOR gain. Results One hundred forty patients (70 with VM) were analyzed. VVOR gain was elevated in 68.6% of patients with VM, compared to 52.9% of patients without VM (p = .057). The AUROC of VVOR gain was 0.5902 (95% confidence interval: 0.4958-0.6846). Vestibular patients with elevated VVOR gain were younger than those with normal/low VVOR gain (mean age 50 vs. 62, p < .0001). A higher proportion of subjects with elevated VVOR gain had symptoms triggered by certain foods (17.6% vs. 5.5%, p = .040) and experienced sound sensitivity (34.1% vs. 18.2%, p = .040) and motion sensitivity (23.5% vs. 9.1%, p = .041). A greater proportion of VM patients with elevated VVOR gain were triggered by certain foods (27.1% vs. 0%, p = .006). Conclusion VVOR gain alone has limited ability to discriminate VM from other vestibular conditions and must be interpreted carefully. VVOR gain elevation may be associated with food triggers and motion and sound sensitivity. Level of Evidence IV.

Abstract
OBJECTIVE Recent evidence has shown that vestibular migraine is strongly associated with cognitive difficulties. However, limited data exist on real-world effects of that dysfunction. The objective of this study is to understand the epidemiology of cognitive dysfunction with vestibular migraine and associated sequelae using National Health Interview Survey data. STUDY DESIGN Randomized, population-based survey study of US adults. SETTING We generated a case definition approximating probable vestibular migraine based on Bárány Society criteria and validated that definition in a tertiary care vestibular clinic. PATIENTS Adult respondents to the 2016 NHIS, which queries a representative sample of the civilian, noninstitutionalized US population. INTERVENTION Diagnostic. MAIN OUTCOME MEASURES We evaluated incidence of self-reported cognitive dysfunction with vestibular migraine and whether individuals were more likely to have impaired mobility, falls, and work absenteeism than those without either condition. RESULTS Among individuals with vestibular migraine, 40% reported "some" and 12% reported "a lot" of difficulty thinking versus 13% and 2% of those without vestibular migraine, respectively. Vestibular migraine sufferers were more likely to have difficulty thinking or remembering compared with respondents without dizziness (odds ratio, 7.43; 95% confidence interval, 6.06-9.10; p < 0.001) when controlled for age, sex, education, stroke, smoking, heart disease, and diabetes. Individuals with both vestibular migraine and cognitive dysfunction had fivefold increased odds of falls and 10-fold increased odds of mobility issues compared with those without either condition. Furthermore, individuals with both vestibular migraine and cognitive dysfunction missed 12.8 more days of work compared to those without either condition. CONCLUSION Our findings indicate vestibular migraine is not only associated with cognitive dysfunction, but they are together associated with mobility issues, fall risk, and work absenteeism.

Abstract
OBJECTIVE To determine the longitudinal incidence of dizziness and its association with demographic factors, neurocognitive effects, functionality, and quality of life. STUDY DESIGN Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) is a prospective, longitudinal cohort study in which TBI patients were assessed at the emergency department and 2-week, 3-month, 6-month, and 12-month follow-up via telephone and/or in-person visits. SETTING Multicenter study in emergency departments of 18 academic medical centers in the United States. PATIENTS A total of 1,514 patients 17 years or older with a diagnosis of TBI, injury occurrence within 24 hours of admission, fluency in English or Spanish, and completed Rivermead Post-Concussion Symptoms Questionnaire (RPQ) at 12 months were enrolled between February 2014 and August 2018. MAIN OUTCOME MEASURE RPQ, Short Form-12 Version 2, Wechsler Adult Intelligence Scale IV, Trail Making Test, Patient Health Questionnaire-9, PROMIS-PAIN, and Glasgow Outcome Scale-Extended Revised. The primary outcome measure was a self-report of "feelings of dizziness" on RPQ at 12 months post-TBI. RESULTS Of the 1,514 participants, 1,002 (66%) were male and 512 (34%) were female. The mean age was 41.6 (SD, 17.4) years. At 12 months, 26% experienced dizziness, with 9% experiencing moderate or severe dizziness. Dizziness was strongly associated with headache (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.92-4.07; p < 0.001), nausea (OR, 4.43; 95% CI, 3.45-5.69; p < 0.001), worse hearing (OR, 3.57; 95% CI, 2.64-4.82; p < 0.001), noise sensitivity (OR, 3.02; 95% CI, 2.54-3.59; p < 0.001), and light sensitivity (OR, 3.51; 95% CI, 2.91-4.23; p < 0.001). In multivariable regression models, participants with severe dizziness demonstrated lower performance compared with those without new or worse dizziness on the Wechsler Adult Intelligence Scale IV (-6.64; p < 0.001), Trail Making Test part A (7.90; p = 0.003) and part B (19.77; p = 0.028), and Short Form-12 physical (-13.60; p < 0.001) and mental health (-11.17; p < 0.001), after controlling for age, sex, education, and TBI severity. CONCLUSION Dizziness is common among TBI patients and relates to quality of life and neurocognitive performance.

Abstract
BACKGROUND Current Bárány Society criteria for vestibular migraine (VM) include only episodic symptoms. Anecdotal observations suggest that some patients have episodic forms and others have chronic forms of VM, with interplay and evolution of both subtypes over time. OBJECTIVE To better understand VM subtypes and evaluate a more inclusive diagnostic schema. METHODS Four VM groups were studied: definite episodic (dVM), probable episodic (pVM), definite chronic (dCVM), and probable chronic (pCVM). Chronic VM was defined as having more than 15 dizzy days per month. Sociodemographic and clinical characteristics were analyzed, along with Dizziness Handicap Inventory (DHI) and Vestibular Migraine Patient Assessment Tool and Handicap Inventory (VM-PATHI) scores. RESULTS 54 adults with a mean age of 47.0 years (SD 13.7) were enrolled. 10 met criteria for dVM, 11 pVM, 22 dCVM, and 11 pCVM. Overall, there were strong similarities in clinical characteristics between dVM, pVM, dCVM, and pCVM. Compared to subjects with episodic VM, those with chronic VM had a higher average number of VM triggers (8.7 vs. 6.4, P = 0.019), including motion (93.9% vs. 66.7%, P = 0.009), scrolling on a screen (78.8% vs. 47.6%, P = 0.018), skipped meal (57.6% vs. 23.8%, P = 0.015), and air travel (57.6% vs. 23.8%, P = 0.015). They also had higher symptom severity (DHI = 53.3, P = 0.194) and burden of disease (VM-PATHI = 48.2, P = 0.030) scores. CONCLUSIONS Many patients do not meet current Bárány Society criteria for VM based on their duration of vestibular symptoms. Yet, these patients with chronic VM endorse several indistinguishable symptoms from those who do meet criteria. A more inclusive diagnostic schema should be adopted where patients with vestibular symptoms shorter than 5 minutes or longer than 72 hours are also recognized as having VM.

Abstract
OBJECTIVE To examine the association between hearing impairment and cognitive function after traumatic brain injury (TBI). SETTING A total of 18 level I trauma centers throughout the United States in the T ransforming R esearch a nd C linical K nowledge in TBI (TRACK-TBI) study. PARTICIPANTS From February 2014 to June 2018, a total of 2697 participants with TBI were enrolled in TRACK-TBI. Key eligibility criteria included external force trauma to the head, presentation to a participating level I trauma center, and receipt of a clinically indicated head computed tomographic (CT) scan within 24 hours of injury. A total of 1267 participants were evaluated in the study, with 216 participants with hearing impairment and 1051 participants without hearing impairment. Those with missing or unknown hearing status or cognitive assessment were excluded from analysis. DESIGN Prospective, observational cohort study. MAIN MEASURES Hearing impairment at 2 weeks post-TBI was based on self-report. Participants who indicated worse hearing in one or both ears were defined as having hearing impairment, whereas those who denied worse hearing in either ear were defined as not having hearing impairment and served as the reference group. Cognitive outcomes at 6 months post-TBI included executive functioning and processing speed, as measured by the Trail Making Test (TMT) B/A and the Wechsler Adult Intelligence Scale, Fourth Edition, Processing Speed Index subscale (WAIS-IV PSI), respectively. RESULTS TBI-related hearing impairment had a small but significantly greater TMT B/A ratio than without TBI-related hearing impairment: mean difference ( B ) = 0.25; 95% CI, 0.07 to 0.43; P = .005. No significant mean differences on WAIS-IV PSI scores were found between participants with and without TBI-related hearing impairment: B = 0.36; 95% CI, -2.07 to 2.60; P = .825. CONCLUSION We conclude that TBI-related hearing impairment at 6 months postinjury was significantly associated with worse executive functioning but not cognitive processing speed.

Abstract
Introduction: The comorbidity of migraine and benign paroxysmal positional vertigo (BPPV) is well-established, yet the impact of migraine on the BPPV phenotype remains understudied. Methods: A retrospective analysis of patients at a tertiary dizziness/vertigo clinic diagnosed with BPPV from 2015 and 2020 was conducted. The study's primary outcomes were the age of BPPV onset, Dizziness Handicap Index (DHI), BPPV recurrence, and dizziness-related falls. Results: In our cohort of 255 BPPV patients, 44.7% had a history of migraine. Those with migraine had an earlier age of BPPV onset than individuals without migraine (60.2 vs. 65.4, p = 0.0018). Migraineurs and non-migraineurs did not differ in their DHI (44.7 vs. 41.6, p= 0.44), recurrence rates (48.3% vs. 40.4%, p= 0.21), and falls (32.5% vs. 37.6%, p = 0.39). Among individuals with horizontal canal BPPV, a higher proportion of migraineurs experienced falls than non-migraineurs (50.0% vs. 6.3%, p = 0.02). Conclusions: Migraineurs experience BPPV at a younger age than those without migraine. This finding suggests that migraine, which has been shown to cause inner ear damage, predisposes individuals to developing BPPV earlier. Migraine was also associated with a higher rate of falls among patients with horizontal canal BPPV, indicating that a migraine history may impact the phenotype of BPPV.

Abstract
OBJECTIVE Extensive animal research has shown that vestibular damage can be associated with cognitive deficits. More recently, new evidence has emerged linking vestibular disorders to cognitive impairment in humans. Herein, we review contemporary research on the pathophysiology of cognitive-vestibular interactions and discuss its emerging clinical relevance. DATA SOURCES PubMed, Embase, and Cochrane databases. REVIEW METHODS A systematic literature search was performed with combinations of search terms: "cognition," "cognitive impairment," "chronic fatigue," "brain fog," "spatial navigation," "attention," "memory," "executive function," "processing speed," and "vestibular hypofunction." Relevant articles were considered for inclusion, including basic and clinical studies, case series, and major reviews. CONCLUSIONS Patients with vestibular disorders can demonstrate long-term deficits in both spatial and nonspatial cognitive domains. The underlying mechanism(s) linking the vestibular system to cognitive function is not well characterized, but several neuro-biologic correlates have been identified. Additional screening tools are required to identify individuals at risk for cognitive impairment, and further research is needed to determine whether treatment of vestibular dysfunction has the capacity to improve cognitive function. IMPLICATIONS FOR PRACTICE Physicians should be aware of emerging data supporting the presence of cognitive deficits in patients with vestibular disorders. Prevention and treatment of long-term cognitive deficits may be possible through screening and rehabilitation.

Abstract
PURPOSE The objective of this study was to use a supervised machine learning (ML) platform and a national dataset to identify factors important in classifying common types of dizziness. METHODS Using established clinical criteria and responses to the balance and dizziness supplement from the 2016 National health Interview Survey (n = 33,028), case definitions for vestibular migraine (VM), benign paroxysmal positional vertigo (BPPV) Ménière's disease (MD), persistent postural-perceptual dizziness (PPPD), superior canal dehiscence (SCD), and bilateral vestibular hypofunction (BVH) were generated. One hundred thirty-six variables consisting of sociodemographic characteristics and medical comorbidities were used to develop decision tree models to predict these common types of dizziness. RESULTS The one-year prevalence of dizziness in the U.S. was 16.8% (5562 respondents). VM was highly prevalent, representing 4.0% of the overall respondents (n = 1327). ML decision tree models were able to correctly classify all 6 dizziness subtypes with high accuracy (sensitivity range, 70-92%; specificity range, 89-99%) using responses to questions about functional limitations due to dizziness, such as falls due to dizziness and modification of social activities due to dizziness. CONCLUSIONS In a large population-based dataset, supervised ML models accurately predicted dizziness subtypes according to responses to questions that do not pertain to dizziness symptoms alone.

Abstract
Objective Vestibular dysfunction is a known risk of cochlear implantation (CI). However, the utility of the physical exam to screen CI candidates for vestibular dysfunction is not well-studied. The objective of this study is to evaluate the preoperative role of the clinical head impulse test (cHIT) in subjects undergoing CI surgery evaluation. Study Design Setting and Subjects We conducted a retrospective review of 64 adult CI candidacy cases between 2017 and 2020 at a tertiary health care center. Methods All patients underwent audiometric testing and evaluation by the senior author. Patients with an abnormal catch-up saccade contralateral to their worse hearing ear during cHIT were referred for formal vestibular testing. Outcomes included clinical and formal vestibular results, operated ear with regard to audiometric and vestibular results, and postoperative vertigo. Results Among all CI candidates, 44% (n = 28) reported preoperative disequilibrium symptoms. Overall, 62% (n = 40) of the cHITs were normal, 33% (n = 21) were abnormal, and 5% (n = 3) were inconclusive. There was one patient who presented with a false positive cHIT. Among the patients who endorsed disequilibrium, 43% had a positive preoperative cHIT. Fourteen percent of the subjects (n = 9) without disequilibrium had an abnormal cHIT. In this cohort, bilateral vestibular impairment (71%) was more common than unilateral vestibular impairment (29%). In 3% of the cases (n = 2), surgical management was revisited or altered due to cHIT findings. Conclusion There is a high prevalence of vestibular hypofunction in the CI candidate population. Self-reported assessments of vestibular function are often not congruent with cHIT results. Clinicians should consider incorporating cHITs as part of the preoperative physical exam to potentially avoid bilateral vestibular dysfunction in a minority of patients.

Abstract
Anterior inferior cerebellar artery (AICA) aneurysms are rare pathologies that may present with hearing loss, facial paralysis, vertigo, and tinnitus. Otologic symptoms at the time of presentation may prompt physicians to order an MRI, which can lead to the misdiagnosis of AICA aneurysms as vestibular schwannomas. We discuss the case of a 27-year-old female who presented with sudden-onset vertigo and right-sided hearing loss. She was found to have a right homogeneously enhancing internal auditory canal (IAC) mass abutting the vestibular nerve on post-gadolinium T1 MRI two hours after the presentation, which was initially diagnosed as a vestibular schwannoma. Serial T1 MRI highlighted the evolution of blood products within this mass by presenting as bright at two days and dark at two months after presentation. Profound ipsilateral sensorineural hearing loss and absent vestibulocochlear function were confirmed on audiometry and vestibular testing, respectively. The diagnostic cerebral angiogram was complicated by an iatrogenic right mid-cervical vertebral artery dissection, and the patient ultimately underwent successful embolization two months after presentation with the resolution of all presenting symptoms except right-sided hearing loss. Early recognition and treatment of an AICA aneurysm may help prevent associated vascular complications, and they should be considered as part of the differential diagnosis for IAC lesions despite their rarity.

Abstract
PURPOSE OF REVIEW The purpose of this narrative review is to discuss current literature about vestibular migraine and other cochleovestibular symptoms related to migraine. RECENT FINDINGS Vestibular migraine affects 2.7% of the US population. Misdiagnosis is common. The pathophysiology is currently unknown but new research shows that calcitonin gene-related peptide, which is implicated in migraine headaches, is expressed in the audiovestibular periphery. A recent large-scale placebo-controlled trial looking at metoprolol for vestibular migraine was terminated early due to poor recruitment; however, at study completion, no differences were seen between treatment arms. Many other audiovestibular symptoms have been shown to be associated with migraine, including tinnitus, hearing loss, aural fullness, otalgia, and sinus symptoms. Migraine is also associated with risk for developing numerous otologic conditions, including Meniere's disease, vestibular loss, Benign Paroxysmal Positional Vertigo, and sudden sensorineural hearing loss. There is now some evidence that patients may experience fluctuating hearing loss and aural fullness without vertigo in association with migraine, which is called cochlear migraine. SUMMARY Migraine can cause a variety of audiologic and vestibular symptoms, and further research is required to understand how migraine affects the inner ear.

Abstract
Introduction While the mechanism of posterior canal benign paroxysmal positional vertigo (BPPV) is widely accepted as canalolithiasis, the pathophysiology of horizontal canal BPPV remains controversial. We seek to analyze vestibular test results of patients with horizontal canal BPPV with ageotropic nystagmus (AHC) and geotropic nystagmus (GHC) in comparison to patients with posterior canal BPPV (PC) to better understand its pathophysiology. Methods In a retrospective chart review of adults with BPPV at a tertiary referral balance center, we reviewed the clinical characteristics and compared videonystagmography, caloric, rotary chair, subjective visual vertical (SVV)/ subjective visual horizontal (SVH), and vestibular evoked myogenic potential (VEMP) results between groups. Results We included 11 AHC and seven GHC patients and randomly selected 20 PC patients as the comparison group. All groups had a high rate of migraine and low rates of diabetes and head trauma, but no difference between groups. Ipsilateral caloric weakness was more prevalent in the GHC group compared to the PC group (p=0.02). One of two AHC patients and both GHC patients who had SVV/SVH testing had abnormal findings. The only AHC patient who had ocular VEMP testing had abnormal results. Additionally, we observed a significant downbeating component to nystagmus (4 deg/sec or greater) exclusively in the AHC group (5/10 patients, p=0.001). Conclusions Patients with AHC and GHC have unique vestibular testing results. In particular, only AHC patients showed a downbeating component to their nystagmus, which may suggest utricular dysfunction in the pathophysiology of AHC.

Abstract
Purpose of Review
To summarize and critically review recent literature on the relative cost-effectiveness of hearing augmentation versus stapes surgery for the treatment of otosclerosis.
Recent Findings
Otosclerosis leads to reduced patient quality of life, which can be ameliorated by either stapes surgery, or hearing aid usage. The success of stapes surgery is high, and the risks of serious postoperative complications are low. Hearing aids don’t have the complications of surgery but are associated with long-term costs. Cost-effectiveness models have shown that stapes surgery is a cost-effective method for treating otosclerosis.
Summary
Both stapes surgery and hearing aids can improve patient-reported quality of life in otosclerosis. Stapes surgery has larger upfront costs and surgical risks, but hearing aids are associated with longer lifetime costs. Stapes surgery is cost-effective for the treatment of otosclerosis.

Abstract
BACKGROUND The Dizziness Handicap Inventory (DHI) measures impairment in quality of life due to dizziness, with higher scores indicating greater impairment. Little is known about the clinical features that predict extremely elevated DHI scores (eeDHI). OBJECTIVE To identify clinical features associated with eeDHI. METHODS A retrospective analysis was conducted of 217 patients with dizziness between October 2016 and April 2019. Patients with eeDHI had DHI scores 1 standard deviation higher than the mean. Analyses were performed to generate odds ratios (OR) for having eeDHI based on clinical features and exam findings. RESULTS The cut-off for eeDHI scores was 71. In total, 20.7% had eeDHI. Logistic regression identified 6 independent predictors for eeDHI scores: numbness in the face or body during dizziness (OR = 5.99, 95% CI 1.77-20.30), history of falls (OR = 4.37, 95% CI 1.74-10.97), female sex (OR = 2.81, 95% CI 1.18-6.66), caloric weakness (OR = 2.61, 95% CI 1.36-5.01), total number of diagnoses associated with dizziness (OR = 2.17, 95% CI 1.11-4.28), and total number of symptoms during dizziness (OR = 1.25, 95% CI 1.07-1.45). CONCLUSIONS These findings suggest that patients with eeDHI have severe disease and should be screened for falls. By understanding the drivers of high DHI scores, we can alleviate disease related suffering for vestibular disorders.

Abstract
Tapia’s syndrome, a unilateral, extracranial combined lesion to the hypoglossal nerve (cranial nerve [CN] XII) and the recurrent laryngeal branch of the vagal nerve (CN X), has been observed to occur after general anesthesia for a variety of surgical procedures. Surgical intraoperative neck positioning and airway management are hypothesized as causative factors. The condition presents with ipsilateral motor paralysis of the tongue and vocal cords. Postoperatively, patients often present with dysphonia, dysphagia, and difficulty swallowing. We discuss a unique case of Tapia’s syndrome occurring after retrosigmoid craniotomy for left vestibular schwannoma resection in a 42-year-old male. General anesthesia was uneventful with an atraumatic, grade 2a intubation and a normal endotracheal tube cuff pressure of 30 cm of water. The patient was positioned laterally, even though the exact head position was not documented. Institutional practice in these cases is for the head to be maintained neutral or with a slight turn. An uneventful subtotal resection of the tumor was performed after retrosigmoid exposure. Postoperatively, the patient complained of left-sided mouth tingling, a hoarse voice, and tongue weakness which impacted his ability to chew and swallow. He had mild left-sided facial weakness and decreased sensation in the V1 and V2 distribution of the trigeminal nerve. Postoperative brain MRI showed postsurgical changes without evidence of neurological or vascular involvement. Fiberoptic endoscopy performed in the otolaryngology clinic showed immobility of the right vocal cord. Consequently, Tapia’s syndrome was diagnosed. He later underwent a right vocal fold injection with Prolaryn gel (Merz North America, Inc, Greensboro, NC, USA) via flexible laryngoscopy with a slight improvement in his dysphonia. At his last visit, he declined further interventions based on acceptable voice quality. Tapia’s syndrome can occur due to the close anatomical proximity of the hypoglossal and recurrent laryngeal nerves as they pass lateral to the oropharynx and hypopharynx. This predisposes the nerves to anesthetic and surgical insults such as over-stretching of the nerves during head manipulation and trauma to the nerve fibers following laryngoscopy. Our case report highlights this potential rare complication to anesthetic and surgical teams. Awareness of this concurrent paralysis can assist practitioners to rapidly diagnose and treat patients who present in this way postoperatively. It can also enable avoidance of causative factors and remind practitioners of the importance of meticulous perioperative documentation.

Abstract
Dizziness is a common chief complaint with an extensive differential diagnosis that ranges from peripheral, central, to nonvestibular conditions. An understanding of nonvestibular conditions will aid accurate diagnosis and initiation of appropriate management. Thus, the objective of this article is to present an overview of nonvestibular etiologies that may plague a dizzy patient and the recommended treatment options.

Abstract
OBJECTIVE Ménière's disease is an inner ear disorder classically characterized by fluctuating hearing loss, tinnitus, and aural fullness accompanied by episodic vertigo. While the pathogenesis of Ménière's remains under debate, histopathological analyses implicate endolymphatic sac dysfunction with inner ear fluid homeostatic dysregulation. Little is known about whether external impingement of the endolymphatic sac by tumors may present with Ménière's-like symptoms. The authors present a case series of 7 patients with posterior fossa meningiomas that involved the endolymphatic sac and new onset of Ménière's-like symptoms and review the literature on this rare clinical entity. METHODS A retrospective review of patients undergoing resection of a posterior petrous meningioma was performed at the authors' institution. Inclusion criteria were age older than 18 years; patients presenting with Ménière's-like symptoms, including episodic vertigo, aural fullness, tinnitus, and/or hearing loss; and tumor location overlying the endolymphatic sac. RESULTS There were 7 cases of posterior petrous face meningiomas involving the vestibular aperture presenting with Ménière's-like symptoms. Imaging and intraoperative examination confirmed no cranial nerve VIII compression or labyrinthine artery involvement accounting for audiovestibular symptoms. Of the 7 patients in the series, 6 experienced significant improvement or resolution of their vertigo, and all 7 had improvement or resolution of their tinnitus after resection. Of the 5 patients who had preoperative hearing loss, 2 experienced improvement or resolution of their ipsilateral preoperative hearing deficit, whereas the other 3 had unchanged hearing loss compared to preoperative evaluation. CONCLUSIONS Petrous face meningiomas overlying the endolymphatic sac can present with a Ménière's syndrome. Early recognition and microsurgical excision of these tumors is critical for resolution of most symptoms and stabilization of hearing loss.

Abstract
OBJECTIVE To perform a systematic review to determine if a total score of ≥14.5 (mean score ≥ 2.1) on the ETDQ-7 accurately identifies patients with obstructive Eustachian tube dysfunction (OETD) on impedance tympanometry (peak compliance <0.2 mL or middle ear pressure of -100 daPa) or other objective measures of OETD. METHODS A systematic review without a meta-analysis was performed of studies in four electronic databases (Pubmed, Embase, Web of Science, and Scopus) that used the ETDQ-7 and at least one objective measure of OETD. RESULTS Six-hundred and fifty-two studies were identified in the initial literature search. Abstracts from 337 studies were screened, followed by full-text review of 61 studies, and qualitative synthesis of 12 studies. Tympanometry was used as an objective measure in ten studies. Eight of the 12 included studies had patient cohort selection bias. Eight studies administered the ETDQ-7 in cohorts of patients with or without OETD, already confirmed on tympanometry, and found a sensitivity of 91%-100% and specificity of 67%-100%. Four studies administered the ETDQ-7 to patients who had not previously undergone objective testing and found a sensitivity of 49%-80% and specificity of 24%-78%. CONCLUSIONS The ETDQ-7 is an important patient-reported outcome measure. However, based upon existing literature, the ETDQ-7 appears limited as a diagnostic tool for OETD or as an objective measure of Eustachian tube function.

Abstract
OBJECTIVES To elucidate differences in demographic and clinical characteristics between patients with episodic and chronic dizziness. METHODS A cross-sectional, observational study of 217 adults referred for dizziness at 1 tertiary center was undertaken. Subjects were split into a chronic dizziness group (>15 dizzy days per month) and an episodic dizziness group (<15 dizzy days per month). RESULTS 217 adults (average age, 53.7 years; 56.7% female) participated. One-third (n = 74) met criteria for chronic dizziness. Dizziness handicap inventory (DHI) scores were significantly higher in those with chronic dizziness compared to those with episodic dizziness (53.9 vs 40.7; P < .001). Comorbid depression and anxiety were more prevalent in those with chronic dizziness (44.6% and 47.3% vs 37.8% and 35.7%, respectively; P > .05). Abnormal vestibular testing and abnormal imaging studies did not differ significantly between the 2 groups. Ménière's disease and BPPV were significantly more common among those with episodic dizziness, while the prevalence of vestibular migraine did not differ according to chronicity of symptoms. A multivariate regression that included age, sex, DHI, history of anxiety and/or depression, associated symptoms, and dizziness triggers was able to account for 15% of the variance in the chronicity of dizziness (pseudo-R2 = 0.15; P < .001). CONCLUSIONS Those who suffer from chronic dizziness have significantly higher DHI and high comorbid rates of depression and anxiety than those with episodic dizziness. Our findings show that factors other than diagnosis alone are important in the chronification of dizziness, an observation that could help improve on multimodal treatment options for this group of patients.

Abstract
Importance During the novel coronavirus disease 2019 pandemic, telehealth has become a vital component of health care delivery. For otolaryngology evaluations, examination of the ear and oropharynx is important but difficult to achieve remotely. Objective To assess the feasibility of patient use of low-cost digital videoscopes and smartphones for examination of the ear and oropharynx. Design, Setting, and Participants A prospective quality improvement study was conducted in an academic adult otolaryngology clinic including 23 patients who presented for an in-person appointment and owned a smartphone device. The study was conducted from July 1 to 15, 2020. Interventions Participants were asked to capture pictures and videos of their ear canals and oropharynx with digital videoscopes and their smartphones under real-time guidance over a telehealth platform. They were then surveyed about their experience. Main Outcomes and Measures The primary outcomes were ratings by health care clinicians and a blinded otolaryngologist reviewer of image acceptability. Secondary outcomes included participant time to image acquisition and willingness to purchase digital videoscopes for telehealth use. Results Of the 23 participants included, 14 were women (61%); mean age was 50 years (range, 21 to 80 years). Of the images obtained using the digital otoscope ear examination, 95% were considered acceptable by the health care clinicians and 91% were considered acceptable by the blinded reviewer; 16 participants (70%) reported that the otoscope was easy to use. The mean time to acquire images for both ears was 114 seconds (95% CI, 84-145 seconds). Twenty-one participants (91%) were willing to pay for a digital otoscope for telehealth use. For the oropharyngeal examination, a greater proportion of smartphone video examinations were considered acceptable by clinicians (63% acceptability) and the blinded reviewer (55%) compared with the digital endoscope (clinicians, 40%; blinded reviewer, 14%). The mean time required for the oropharyngeal examination smartphone video capture was shorter at 35 seconds compared with both the digital endoscope (difference, -27 seconds; 95% CI, -7 to -47 seconds) and smartphone photo capture (difference, -53 seconds; 95% CI, -20 to -87 seconds). Conclusions and Relevance Digital otoscopes and smartphones apparently can facilitate remote head and neck physical examination in telehealth. Digital otoscopes were useful for ear examinations, and smartphone videos appeared to be the most useful for oropharyngeal examinations. Further studies are required to determine specific diagnostic capabilities in various telehealth practice settings.

Abstract
Cerebrospinal fluid (CSF) fistulae originating from the fallopian canal of the facial nerve is hypothesized to arise due to atypical patterns of subarachnoid space extension into the geniculate ganglion or more distal regions along the intratemporal course of the facial nerve, but its pathogenesis remains poorly understood. Although a rare etiology of CSF fistulae of the temporal bone, there are significant clinical ramifications due to the risk of recurrent meningitis, difficulty in identifying the anatomic location of the CSF leak, and technical challenges associated with surgical repair. We present three clinical cases of arachnoid cysts within the geniculate fossa with or without CSF fistulization and provide histopathologic correlates of this rare clinical phenomenon from a human temporal bone collection. The pediatric and adult patients presented suggest differential pathophysiologic mechanisms associated with CSF fistulae. Temporal bone histology reveals atypical patterns of subarachnoid space extension in the fallopian canal that may underlie arachnoid cyst formation and overt CSF leak from the geniculate region.

Abstract
Introduction: High-resolution temporal bone computed tomography (CT) is considered the gold standard for diagnosing superior semicircular canal dehiscence (SCD). However, CT has been shown over-detect SCD and provide results that may not align with patient-reported symptoms. Ocular vestibular-evoked myogenic potentials (oVEMPs)—most commonly conducted at 500 Hz stimulation—are increasingly used to support the diagnosis and management of SCD. Previous research reported that stimulation at higher frequencies such as 4 kHz can have near-perfect sensitivity and specificity in detecting radiographic SCD. With a larger cohort, we seek to understand the sensitivity and specificity of 4 kHz oVEMPs for detecting clinically significant SCD, as well as subgroups of radiographic, symptomatic, and surgical SCD. We also investigate whether assessing the 4 kHz oVEMP n10-p15 amplitude rather than the binary n10 response alone would optimize the detection of SCD. Methods: We conducted a cross-sectional study of patients who have undergone oVEMP testing at 4 kHz. Using the diagnostic criteria proposed by Ward et al., patients were determined to have SCD if dehiscence was confirmed on temporal bone CT by two reviewers, patient-reported characteristic symptoms, and if they had at least one positive vestibular or audiometric test suggestive of SCD. Receiver operating characteristic (ROC) analysis was conducted to identify the optimal 4 kHz oVEMP amplitude cut-off. Comparison of 4 kHz oVEMP amplitude across radiographic, symptomatic, and surgical SCD subgroups was conducted using the Mann-Whitney U test. Results: Nine hundred two patients (n, ears = 1,804) underwent 4 kHz oVEMP testing. After evaluating 150 temporal bone CTs, we identified 49 patients (n, ears = 61) who had radiographic SCD. Of those, 33 patients (n, ears = 37) were determined to have clinically significant SCD. For this study cohort, 4 kHz oVEMP responses had a sensitivity of 86.5% and a specificity of 87.8%. ROC analysis demonstrated that accounting for the inter-amplitude of 4 kHz oVEMP was more accurate in detecting SCD than the presence of n10 response alone (AUC 91 vs. 87%). Additionally, using an amplitude cut-off of 15uV reduces false positive results and improves specificity to 96.8%. Assessing 4 kHz oVEMP response across SCD subgroups demonstrated that surgical and symptomatic SCD cases had significantly higher amplitudes, while radiographic SCD cases without characteristic symptoms had similar amplitudes compared to cases without evidence of SCD. Conclusion: Our results suggest that accounting for 4 kHz oVEMP amplitude can improve detection of SCD compared to the binary presence of n10 response. The 4 kHz oVEMP amplitude cut-off that maximizes sensitivity and specificity for our cohort is 15 uV. Our results also suggest that 4 kHz oVEMP amplitudes align better with symptomatic SCD cases compared to cases in which there is radiographic SCD but no characteristic symptoms.

Abstract
Vestibular schwannoma (VS) is associated with dizziness and vertigo during all stages of treatment. This report describes a patient who presented with a one-year history of intermittent motion sickness, dizziness, headache, imbalance, and nausea. MRI showed a right-side VS in the cerebellopontine angle and internal auditory canal. The patient elected to undergo Gamma Knife radiosurgery for treatment. Within two to three months, she continued to experience recurring dizziness, vertigo, neck stiffness, and head pressure. She was referred for neurotology evaluation, which led to a diagnosis of vestibular migraine (VM). Her vestibular reflexes were intact. Subsequently, she was treated with diet modification and low-dose venlafaxine. She reported dramatically improved dizziness and vertigo symptoms at six-month follow-up. VM is a very common cause of dizziness that should always be included in the differential diagnosis, even in VS patients.

Abstract
Over the past 50 years, incredible progress has been made with implantable devices. Management can become complex, as unique issues arise with interaction of these devices with other devices and technologies. The cochlear implant (CI) is the most commonly implanted device in the head and neck. Because of its internal magnet, CIs can interfere with MRI, causing imaging artifacts, pain, and device complications. Other implants demonstrate similar issues with imaging and co-implantation. This article provides an overview of special considerations regarding neurostimulation devices within the head and neck. We focus on interactions between implantable devices and other technologies or devices.

Abstract
Introduction Microvascular free flaps offer an alternative to local and regional flaps for coverage of complex or large skull base defects. Routes and approaches to these reconstructive options are complicated and require an understanding of complex head and neck anatomy. Methods A systematic review of the literature was performed using a set of search terms with the help of a qualified librarian. Articles were reviewed and selected for inclusion based on relevance. We were interested in reporting possible routes for free flap accessibility to the skull base as well as microvascular vessel options, as this choice may affect the geometry and accessibility to the defect. Results A total of 1,917 articles were obtained from a comprehensive search and 11 articles were ultimately found to be relevant to this review. Published options for vessel anastomosis and corridors to the skull base following endoscopic endonasal surgery are reviewed, including Caldwell-Luc/transbuccal space, prevertebral space, transpterygoid/parapharyngeal, and transmaxillary approaches. Conclusion The field of endoscopic surgery has continued to advance and provide options for tumors of the skull base. This has led to a need for creative routes to the skull base for free flap reconstruction.

Isolated malleus fractures are an infrequent cause of hearing loss. Even more unusual is a fracture secondary to a sneeze. Here, we review the case of a 32-year-old man with the first surgically confirmed malleus fracture due to a suppressed sneeze, which was then successfully repaired with hydroxyapatite bone cement. We discuss the presentation, diagnosis, and management of this patient and review the literature on isolated malleus injuries.

Abstract
Soft palate (SP) reconstruction remains a challenge for the head and neck reconstructive surgeon. One favorable local flap option is the longus capitis muscle (LCM), a deep neck flexor with redundant muscle function, appropriate bulk, and a relatively straightforward surgical harvest. A retrospective review of 3 patients with T2 to T4 tonsil squamous cell carcinoma requiring SP resection and LCM reconstruction at a single institution was performed. Three patients underwent primary transoral resection, all resulting in at least 50% full-thickness SP defects. Reconstruction comprised a superiorly based LCM local flap. Patients underwent adjuvant (chemo)radiation therapy as indicated. Within 3 to 8 months, each patient was tolerating a full oral diet with no dysphagia, nasal regurgitation, or velopharyngeal insufficiency. For select patients with SP defects, a superiorly based LCM flap may provide a functionally acceptable reconstruction with minimal donor site morbidity.

Abstract
Background:According to population-based studies that estimate disease prevalence, the majority of patients evaluated at dizziness clinics receive a single vestibular diagnosis. However, accumulating literature supports the notion that different vestibular disorders are interrelated and often underdiagnosed.Objective:Given the complexity and richness of these interrelations, we propose that a more inclusive conceptual framework to vestibular diagnostics that explicitly acknowledges this web of association will better inform vestibular differential diagnosis.Methods:A narrative review was performed using PubMed database. Articles were included if they defined a cohort of patients, who were given specific vestibular diagnosis. The interrelations among vestibular disorders were analyzed and placed within a conceptual framework.Results:The frequency of patients currently receiving multiple vestibular diagnoses in dizziness clinic is approximately 3.7% (1263/33 968 patients). The most common vestibular diagnoses encountered in the dizziness clinic include benign paroxysmal positional vertigo (BPPV), vestibular migraine, vestibular neuritis, and Ménière’s disease.Conclusions:A review of the literature demonstrates an intricate web of interconnections among different vestibular disorders such as BPPV, vestibular migraine, Ménière’s disease, vestibular neuritis, bilateral vestibulopathy, superior canal dehiscence syndrome, persistent postural perceptual dizziness, anxiety, head trauma, and aging, among others.

Abstract
Although radiation-based treatment for nasopharyngeal cancer may achieve excellent long term oncologic results, late effects of therapy may lead to soft tissue radionecrosis and velopharyngeal insufficiency (VPI). Repair of these oro- and nasopharyngeal defects presents a complex reconstructive challenge. We present a case of a long-term survivor treated with chemoradiotherapy for nasopharyngeal cancer who developed progressive dysphagia, velopharyngeal insufficiency, and radionecrosis of the nasopharynx and soft palate, leading to tracheostomy and gastrostomy tube dependence. A staged reconstruction was performed, initially with a tubed nasoseptal flap for a creation of a mucosal-lined nasopharyngeal port. An adipofascial anterolateral thigh free flap was subsequently performed for soft palate reconstruction. Within 2 months, the oropharyngeal reconstruction had remucosalized and she was decannulated, taking an oral diet. Her speech was intelligible and she had good nasal breathing without symptoms of velopharyngeal insufficiency.

Abstract
OBJECTIVE To study the quality and usability of magnetic resonance imaging (MRI) obtained with a cochlear implant magnet in situ. STUDY DESIGN Retrospective chart review. SETTING Tertiary care center. PATIENTS All patients who underwent brain MRI with a cochlear implant magnet in situ from 2007 to 2016. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Grade of view of the ipsilateral internal auditory canal (IAC) and cerebellopontine angle (CPA). RESULTS Inclusion criteria were met by 765 image sequences in 57 MRI brain scans. For the ipsilateral IAC, significant predictors of a grade 1 (normal) view included: absence of fat saturation algorithm (p = 0.001), nonaxial plane of imaging (p = 0.01), and contrast administration (p = 0.001). For the ipsilateral CPA, significant predictors of a grade 1 view included: absence of fat saturation algorithm (p = 0.001), high-resolution images (p = 0.001), and nonaxial plane of imaging (p = 0.001). Overall, coronal T1 high-resolution images produced the highest percentage of grade 1 views (89%). Fat saturation also caused a secondary ring-shaped distortion artifact, which impaired the view of the contralateral CPA 52.7% of the time, and the contralateral IAC 42.8% of the time. MRI scans without any usable (grade 1) sequences had fewer overall sequences (N = 4.3) than scans with at least one usable sequence (N = 7.1, p = 0.001). CONCLUSION MRI image quality with a cochlear implant magnet in situ depends on several factors, which can be modified to maximize image quality in this unique patient population.

Abstract
Objective To determine the incidence of surgical complications associated with superior canal dehiscence syndrome (SCDS) repair and identify the demographic, medical, and intraoperative risk factors that are associated with SCDS complications. Study Design Cases series with chart review, including patients who underwent SCDS repair between 1996 and 2015. Setting A tertiary care academic medical center. Subjects and Methods Data were collected from 220 patients, including demographic information, medical comorbidities, prior otologic surgical history, surgical approach, intraoperative findings, and postoperative complications. Relative risk analysis and multivariable logistic regression evaluated the associations between perioperative risk factors and SCDS complications. Results A total of 242 consecutive cases were performed: 95.5% middle fossa and 4.5% transmastoid approach (mean age: 47.8 ± 10.6 years; 54.5% female). Surgical complications were reported in 27 (11.2%) cases; 20 (8.3%) had Clavien-Dindo grade I complications, most commonly benign paroxysmal positional vertigo (n = 11, 4.5%) and profound sensorineural hearing loss (n = 6, 2.5%). Two cases (0.8%) had grade II; 4 cases (1.7%), grade III; and 1 case (0.4%), grade IV complications. In the analysis of comorbidities, only preoperative coagulopathy was significantly associated with increased risk of complications (relative risk = 6.4, P < .01). Following multivariate logistic regression adjusting for demographic covariates, coagulopathy was still associated with increased odds of complications (odds ratio = 15.7, P = .03). There were no significant associations between other risk factors and complications. Conclusion SCDS repair has low rates of adverse events. We observed an incidence of 11.2% complications, most commonly postoperative benign paroxysmal positional vertigo. The risk of nonotologic intracranial complications (1.7%) is low.

Abstract
While infrequent, cerebrospinal fluid (CSF) leaks are known to occur after surgical resection of vestibular schwannomas. Early signs of CSF leak often include headache and altered mental status. If untreated, life-threatening complications can occur, including brainstem herniation and meningitis. The appropriate surgical treatment for a CSF leak requires accurate localization of the source. While the most likely location of a CSF leak after lateral skull base surgery is through the aerated portions of the temporal bone, we present a unique case of a man with a prolonged CSF leak after an acoustic tumor removal who was ultimately found to have an occult spinal perineural (Tarlov) cyst as the source. Accurate localization was ultimately achieved with CT myelogram after empirically obliterating his mastoid failed to restore intracranial CSF volume. Tarlov cysts are the most common cause of idiopathic intracranial hypotension, and this case highlights the importance of considering this entity in the differential diagnosis of postoperative CSF leaks.

Abstract
IMPORTANCE The hypoglossal nerve has long been an axonal source for reinnervation of the paralyzed face. In this study, we report our experience with transposition of the intratemporal facial nerve to the hypoglossal nerve for facial reanimation. OBJECTIVES To determine the feasibility and outcomes of the transposition of the infratemeporal facial nerve for end-to-side coaptation to the hypoglossal nerve for facial reanimation. DESIGN, SETTINGS, AND PARTICIPANTS A case series of 20 patients with facial paralysis who underwent mobilization and transposition of the intratemporal segment of the facial nerve for an end-to-side coaptation to the hypoglossal nerve (the VII to XII technique). Participants were treated between January 2007 and December 2014 at a tertiary care center. MAIN OUTCOMES AND MEASURES Outcome measures include paralysis duration, facial tone, facial symmetry at rest, and with smile, oral commissure excursion, post-reanimation volitional smile, and synkinesis. METHODS Demographic data, the effects of this technique on facial tone, symmetry, oral commissure excursion and smile recovery were evaluated. Preoperative and postoperative photography and videography were reviewed. Facial symmetry was assessed with a facial asymmetry index. Smile outcomes were evaluated with a visual smile recovery scale, and lip excursion was assessed with the MEEI-SMILE system. RESULTS All 20 patients had adequate length of facial nerve mobilized for direct end-to-side coaptation to the hypoglossal nerve. The median duration of facial paralysis prior to treatment was 11.4 months. Median follow-up time was 29 months. Three patients were excluded from functional analysis due to lack of follow-up. Facial symmetry at rest and during animation improved in 16 of 17 patients. The median (range) time for return of facial muscle tone was 7.3 (2.0-12.0) months. A significant reduction in facial asymmetry index occurred at rest and with movement. The MEEI FACE-gram software detected a significant increase in horizontal, vertical, overall lip excursion and smile angle. No patient developed significant tongue atrophy, impaired tongue mobility, or speech or swallow dysfunction. CONCLUSIONS AND RELEVENCE Mobilization of the intratemporal segment of the facial nerve provides adequate length for direct end-to-end coaptation to the hypoglossal nerve and is effective in restoring facial tone and symmetry after facial paralysis. The resulting smile is symmetric or nearly symmetric in the majority of patients with varying degree of dental show. The additional length provided by utilizing the intratemporal segment of the facial nerve reduces the deficits associated with complete hypoglossal division/splitting, and avoids the need for interposition grafts and multiple coaptation sites.

Abstract
Cochlear implant (CI) surgery in the setting of an open mastoid cavity is evolving. Two strategies are commonly pursued: a staged approach, clearing the disease, closing the meatus or the external auditory canal (EAC), and reevaluating in 3 to 6 months prior to implantation, or a single-stage procedure with mastoid obliteration without EAC closure. Meatal closure is often employed in the setting of an open mastoid cavity to reduce the risk of electrode extrusion and infection. An open cavity offers the advantages of being a single-stage procedure, permitting direct surveillance for recurrent cholesteatoma, and reducing the need for repeat computed tomography scans. We describe an approach to the coverage of a CI within a dry, open mastoid cavity using an anteriorly-based postauricular pericranial flap.

Abstract
IMPORTANCE Reconstruction of the scalp after acquired defects remains a common challenge for the reconstructive surgeon, especially in a patient with a history of radiation to the area. OBJECTIVE To review the current literature and describe a novel algorithm to help guide the reconstructive surgeon in determining the optimal reconstruction from a cosmetic and functional standpoint. Pertinent surgical anatomy, considerations for patient and technique selection, reconstructive goals, as well as the reconstructive ladder, are also discussed. EVIDENCE REVIEW A PubMed and Medline search was performed of the entire English literature with respect to scalp reconstruction. Priority of review was given to those studies with higher-quality levels of evidence. FINDINGS Size, location, radiation history, and potential for hairline distortion are important factors in determining the ideal reconstruction. The tighter and looser areas of the scalp play a major role in the potential for primary or local flap closure. Patients with medium to large defects and a history of radiation will likely benefit from free tissue transfer. CONCLUSIONS AND RELEVANCE Ideal reconstruction of scalp defects relies on a comprehensive understanding of scalp anatomy, a full consideration of the armamentarium of surgical techniques, and a detailed appraisal of patient factors and expectations. The simplest reconstruction should be used whenever possible to provide the most functional and aesthetic scalp reconstruction, with the least amount of complexity. LEVEL OF EVIDENCE NA.

Abstract
Objectives To review the indications, techniques, and outcomes for a series of patients in whom the lower trapezius flaps was used for repair of complex posterior scalp and neck defects after posterior occipital-cervical surgeries. Design Retrospective case series. Setting Tertiary academic hospital. Participants A retrospective review of cases that required complex occipital-cervical repair was performed to identify patients who underwent reconstruction using the lower trapezius flap. Data collected included demographics, clinical presentations, surgical anatomy, operative techniques, and outcomes with review of the pertinent literature. Outcomes Nine patients who underwent reconstruction using the lower trapezius flap were identified. Prior surgical interventions included five complex tumor resections, two patients with multiple instrumented cervical spine surgeries, one patient with a craniotomy for attempted extracranial to intracranial arterial bypass for a basilar aneurysm repair, and a posterior occipital-cervical decompression after trauma. During the median follow-up period of 7 months, all nine single-stage reconstructions resulted in successful healing without major surgical complications. Conclusion Lower trapezius island flaps provide a reliable option for the reconstruction of complex scalp and neck defects that develop after complex occipital-cervical surgeries.
