Objective: Describe a series of cases of idiopathic chronic auricular chondritis refractory to antibiotics and steroids treated successfully with surgery. Study Design: Case series. Setting: Two tertiary academic medical centers. Patients: We analyzed four patients diagnosed with chronic auricular deformity, pain, and drainage for a period of 1 to 5 years who had failed prolonged treatment consisting of antibiotics, corticosteroids, and incision and drainage. All four patients were smokers, three were diabetic, and two had a history of bariatric surgery. Interventions: Operative subcutaneous partial auriculectomy (removal of diseased cartilage and excess skin) was performed. Main Outcome Measures: Resolution of pain and drainage, need for additional procedures, and reduction in narcotics required for pain control were analyzed. Results: Two of the four patients were given an immediate postoperative course of doxycycline and ciprofloxacin. With a minimum of 6 weeks’ follow-up, all four patients had complete resolution of pain and recurrent drainage postoperatively. One patient requiring daily narcotic medication for pain and benzodiazepine for sleep preoperatively no longer required prescription medication. All specimens revealed chronic dermal and cartilage inflammation. Three of four cases had polymicrobial infection. One case had only skin contaminant growth on culture following multiple oral and parental antibiotic regimens. Conclusions: Surgical excision of diseased cartilage as a result of idiopathic chronic chondritis is an effective treatment in those cases refractory to antibiotics and incision and drainage, and should be considered in the treatment algorithm for similar patients, potentially offering definitive cure.

ObjectiveTo evaluate patients who become symptomatic from superior semicircular canal dehiscence (SSCD) following head trauma.Study DesignCase series assessing patients presenting with SSCD after a trauma.MethodsA case series was completed assessing patients presenting with SSCD after trauma. Data from three academic medical centers were evaluated, including the following: imaging, videonystagmography (VNG)/vestibular evoked myogenic potential (VEMP) testing, audiometric assessment, and surgical repair. Outcome measures included the following: 1) Description of audio‐vestibular symptoms, 2) mean pre‐ and post‐operative pure tone average (PTA), word recognition score (WRS), and air bone gap (ABG).ResultsA total of 14 patients were included; 86% were male. Approximately 43% were found to have bilateral SSCD on imaging, with 57% of patients pursuing surgical management. The most common presenting symptoms included pulsatile tinnitus (93%), autophony (79%), and hearing loss (64%). Approximately 36% of patients underwent VNG/VEMP testing, with 83.3% of those demonstrating abnormal results. The mean audiometric findings on the symptomatic side included an air‐conduction PTA of 38.0 dB, bone‐conduction PTA of 24.3 dB, WRS of 81%, and ABG of 17.9 dB. Among patients who underwent surgery (57%), there was no significant change in the air‐conduction PTA, bone‐conduction PTA, or WRS (P > .05). However, there was an improvement in the ABG (preoperative = 22.8 dB versus postoperative = 9.7 dB; P = .005).ConclusionHead trauma may be a potentiating event for SSCD syndrome. This study advances the hypothesis that these patients likely have underlying radiographic SSCD prior to their trauma, and a traumatic event increases in intra‐vestibular or intracranial pressures, unmasking SSCD syndrome.Level of Evidence4 Laryngoscope, 131:E2810–E2818, 2021

Introduction: Heart Disease and Stroke Statistics_2014 Update suggests more than 424,000 people suffer out of hospital cardiac arrest (OHCA) in the United States. Hypothesis: We assessed seasonal variation in OHCA from a large national hospitalisation database in the past decade. Methods: The Nationwide Inpatient Sample database was used to estimate the annual number of hospitalisations with from 2000-2011. Identification of out of hospital cardiac arrest related hospitalisations was based on the designation of the International Classification of Diseases (9th Edition) Clinical Modification (ICD-9-CM) diagnosis code 427.5 (OHCA) as the principal discharge diagnosis. The frequency of hospitalisation for each month cumulative over 11 years was calculated and divided by number of days in that month to obtain the mean hospitalisations per day for each month. All calculations were carried out using the weighted estimates approximating nationwide population estimates. Results: An estimated 93,209 hospitalisations with primary diagnosis of OHCA occurred in the United States from the beginning of the calendar year 2000 to the end of the calendar year 2011. The number of hospitalisations per day in each month is shown in Figure 1.The number of hospitalisation was maximum in the winter months and minimum in summer months. Specifically, the mean number of hospitalisation each day (averaged over 11 years) was least in August (242). There was a rising trend from August to January. The average number of hospitalisation was highest in January (310); thereafter, the hospitalisation rate dropped to a nadir in August. There was however no seasonal pattern in inhospital mortality. Conclusions: We identified for the first time in United States an impressive pattern of seasonal variation in hospitalisations for OHCA. Further efforts must be made to identify triggers and methods to prevent OHCA and reduce its burden on health care system.

Objective: To identify possible racial and/or health insurance disparities with respect to ablation procedures for atrial fibrillation (AF). Method: Using the Nationwide Inpatient Sample (2000-2011), we identified adult patients (pts) admitted with principle diagnosis of AF by ICD 9 code 427.31 who had catheter ablation (ICD 9 code - 37.34). We stratified patients by race (White, Black, Hispanic, and other minority racial groups), insurance status, age, gender, type of hospital, and type of hospital admission. A hierarchical mixed effect multivariate model was created to identify independent predictors of AF ablation. Results: Among 4,547,144 patients hospitalized with AF during the study period, 201,447(4.43%) underwent ablation procedures. In absolute numbers, the majority of the ablations were performed in Whites (65.7%) and patients with Medicare (66.7%) or private insurance (24.7%). After adjusting for confounding factors, the proportions of Black pts (compare to White), and Medicare, Medicaid, and Uninsured pts (compare to private insurance), receiving ablation therapy were lower (see table). Odds of having ablation were lower in older and female patients and higher in teaching hospitals and after elective admissions (p<0.001 for all comparisions). Similar racial and insurance disparities were observed over the time course of the study. Conclusion: We identified lower rates of AF ablation among black pts even after correction of other factors such as insurance. Ablation rates were also lower among patients without private insurance. These trends persisted during the study period of 2000-2011.

Objective: To identify racial and/or health insurance disparities in the population undergoing ablation for paroxysmal supraventricular tachycardia(PSVT). Method: We identified adult patients (pts) admitted with principle diagnosis of PSVT by ICD 9 code 427.0 who had catheter ablation (ICD 9 code - 37.34), using the Nationwide Inpatient Sample (2000-2011). We stratified patients by race (White, Black, Hispanic, and other minority racial groups)and insurance status, and a hierarchical mixed effect multivariate model was created to identify independent predictors of PSVT ablation. Results: 64,564(20.2%) patients underwent ablation out of 319,579 patients admitted for PSVT during the period of 2000-2011. In absolute numbers, the majority of ablations were performed in Whites (58.7%) and patients with Medicare (56.3%) or private insurance (30.1%). After adjusting for confounding factors, the odds of having ablation were lower in Black pts (compare to White), and Medicare, Medicaid, and Uninsured pts (compare to private insurance) (see table). Other predictors of lower rate of ablations were: older age and female patients while odds of receiving ablation were higher for elective admissions and in teaching hospitals (p<0.001 for all comparisons). Conclusion: In a population of pts admitted for PSVT, those without private insurance and Black pts were less like to be treated with catheter ablation; and, this disparity persisted from 2000-2011. Since catheter ablation for PSVT is generally considered a curative procedure, future studies are needed to identify the factors that lead to these disparities of care.

Abstract Trigeminal nerve schwannomas (TNSs) are rare lesions that typically present with symptoms of trigeminal neuropathy or other cranial nerve palsies. These lesions classically have a dumbbell shape, with an anterior component within Meckel's cave and posterior component extending into the posterior fossa through the porus trigeminus. Surgical resection of TNSs can often be achieved via an extradural subtemporal approach to Meckel's cave without an anterior petrousectomy, even for tumors with a significant posterior fossa component, as the tumor often erodes a portion of the petrous apex. 1 We present the case of a 53-yr-old female presenting to our institution with complete trigeminal neuropathy secondary to a right-sided, previously resected and radiated TNS. Serial imaging demonstrated an interval growth of significant residual tumor despite multiple adjuvant therapies, and, thus, the patient was recommended to undergo additional surgical resection. The lesion was approached through a right-sided subtemporal approach to Meckel's cave, 2 with a plan to utilize an anterior petrousectomy only if difficulty resecting the posterior fossa component of the tumor was encountered. Intraoperatively, the posterior fossa component was found to be densely adherent to the adjacent brainstem, likely secondary to prior surgery and radiation therapy, and, thus, an anterior petrousectomy was performed. Postoperatively, the patient had stable trigeminal neuropathy without any new neurological deficits and a magnetic resonance imaging (MRI) confirmed a gross total resection. In the accompanying video, we hope to demonstrate the steps and nuances of both the subtemporal approach to accessing Meckel's cave and anterior petrousectomy when employed for the resection of TNSs. The patient in question provided formal consent for the making of this video.

ObjectiveThe degree to which various treatment modalities modify vestibular schwannoma (VS)–associated symptoms has received limited attention. The purpose of this study was to determine how different treatment modalities affect subjective symptoms in those presenting with VS.Study DesignProspective survey.SettingTertiary neurotology referral center.MethodsPatients with sporadic VS who received treatment at our institution were prospectively surveyed with a VS symptom questionnaire. Those who completed a baseline survey prior to treatment and at least 1 posttreatment survey were included. The prospective survey evaluated the severity of self‐reported symptoms (Likert scale, 1‐10), including tinnitus, dizziness or imbalance, headaches, and hearing loss.ResultsA total of 244 patients were included (mean age, 57 years). The mean duration of follow‐up was 2.1 years, and the median number of surveys completed was 2 (interquartile range, 1‐3). Seventy‐eight (32%) cases were managed with observation, 118 (48%) with microsurgery, and 48 (20%) with radiosurgery. Multivariable analyses revealed no statistically significant difference in the change in tinnitus (P =. 15), dizziness or imbalance (P = 0.66), or headaches (P =. 24) among treatment groups. Evaluation of clinically important differences demonstrated that microsurgery leads to significant bidirectional changes in headaches.ConclusionsLimited prospective data exist regarding the progression or resolution of subjective symptoms in those presenting with VS. This study suggests that tinnitus, dizziness or imbalance, and headaches are unlikely to be significantly modified by treatment modality and generally should not be used to direct treatment choice.

Background: Previous cross-sectional studies analyzing quality of life (QOL) outcomes in patients with sporadic vestibular schwannoma (VS) have shown surprisingly little difference among treatment modalities. To date, there is limited prospective QOL outcome data available comparing baseline to posttreatment scores. Study Design: Prospective longitudinal study using the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL) scale. Setting: Large academic skull base center. Patients: Patients diagnosed with unilateral VS who completed a baseline survey before treatment and at least one posttreatment survey. Main Outcome Measures: Change in PANQOL scores from baseline to most recent survey. Results: A total of 244 patients were studied, including 78 (32%) who elected observation, 118 (48%) microsurgery, and 48 (20%) stereotactic radiosurgery. Patients who underwent microsurgery were younger (p < 0.001) and had larger tumors (p < 0.001) than those who underwent observation or radiosurgery; there was no significant difference in duration of follow-up among management groups (mean 2.1 yrs; p = 0.28). When comparing the total PANQOL score at baseline to the most recent survey, the net change was only –1.1, –0.1, and 0.3 points on a 100-point scale for observation, microsurgery, and radiosurgery, respectively (p = 0.89). After multivariable adjustment for baseline features, there were no statistically significant changes when comparing baseline to most recent scores within each management group for facial function, general health, balance, hearing loss, energy, and pain domains or total score. However, the microsurgical group experienced a 10.8-point improvement (p = 0.002) in anxiety following treatment, compared with 1.5 (p = 0.73) and 5.3 (p = 0.31) for observation and radiosurgery, respectively. Conclusions: In this prospective longitudinal study investigating differences in QOL outcomes among VS treatment groups using the disease-specific PANQOL instrument, treatment did not modify QOL in most domains. Microsurgery may confer an advantage with regard to patient anxiety, presumably relating to the psychological benefit of “cure” from having the tumor removed.

Objective: To evaluate adverse events and feasibility of performing 1.5-T MRI in patients with cochlear implants (CI) and auditory brainstem implants (ABI). Setting: Single tertiary academic referral center. Patients: CI and ABI recipients undergoing 1.5-T MRI without internal magnet removal. Intervention(s): MRI after tight headwrap application. Main Outcome Measures: Adverse events, patient tolerance. Results: A total of 131 MR studies in 79 patients were performed, with a total of 157 study ears. Sixty-one patients (77%) had unilateral devices. Four patients (5%) underwent MRI with ABI magnets in place. Sixteen patients (20%) had MRI-compatible devices that did not require a head wrap. There were no instances of device stimulation, device malfunction, or excessive heating of the receiver-stimulator package. Magnet tilt requiring manual repositioning occurred during seven studies (4.5%) and magnet displacement requiring operative intervention occurred during seven studies (4.5%). Significant pain where imaging had to be discontinued occurred during three episodes (2%). No adverse events were noted among patients who underwent MRI with an MRI-compatible magnet. Conclusions: MRI with CI or ABI magnets in place is associated with a low prevalence of adverse events when performed in a controlled setting. Many partial magnet displacements can be corrected with firm manual pressure. Devices with magnets that align with the field within their housing were not associated with any adverse events and do not require immobilization of the magnet during the scan. These may be valuable in patients with known or anticipated need for MRI.
