RESUMO

Tophaceous gout of the middle ear is a rare occurrence that presents as a granular white-colored mass. It is frequently misdiagnosed as cholesteatoma or tympanosclerosis in patients who otherwise may not manifest any clinical or biochemical signs of gout. While uncommon, it can lead to clinically significant disease such as conductive hearing loss. The present report describes 2 cases of middle ear gouty tophi initially mistaken for another entity. Both patients underwent surgery, and the diagnosis of gout was revealed after final histopathological analysis. A review of the literature is also presented.

RESUMO

BACKGROUND: A rare subset of sarcoidosis, neurosarcoidosis, is reported to occur in 5-7% of sarcoid patients and can manifest in a variety of ways. The most common are facial paralysis and optic neuritis, less commonly causing cochleovestibulopathy, blindness, anosmia, and other cranial nerve (CN) palsies. The sensory deficit may be severe and psychiatric symptoms may result from the effects of the disease or steroid treatment. Although MRI-compatible cochlear implants are now available, concerns about the feasibility of recoverable hearing with cochlear implantation in these patients as well as the practical difficulty of disease monitoring due to implant artifact must be considered. RESULTS: We present 3 recent cases from different institutions. The first is a 39-year-old man with a history of progressively worsening hearing loss, followed by visual loss, delusions, agitation, ataxia, and musical auditory hallucinations, diffuse leptomeningeal enhancement on MRI with a normal serum angiotensin-converting enzyme (ACE) level but elevated cerebrospinal fluid (CSF) ACE levels, suggesting neurosarcoidosis, was treated with corticosteroids, and underwent successful cochlear implantation. The second is a 36-year-old woman with rapid-onset horizontal diplopia, left mixed severe sensorineural hearing loss (SNHL) and tinnitus, diffuse leptomeningeal enhancement on MRI, and progressive palsy of the left CNs IV, VI, VII, IX, X and XI, with altered mental status requiring admission following high-dose intravenous corticosteroids. The third is a 15-year-old boy who presented with sudden, bilateral, profound SNHL, recurrent headaches, and left facial weakness refractory to antivirals, ultimately diagnosed with neurosarcoidosis following an aborted cochlear implantation where diffuse inflammation was found, and histopathology revealed Schaumann bodies; he was treated with methotrexate and later underwent successful cochlear implantation. CONCLUSIONS: Neurosarcoidosis is an elusive diagnosis and can cause hearing loss and psychiatric symptoms. Cochlear implantation for patients with severe hearing loss should be considered once the diagnosis is confirmed, as it is possible to achieve a successful level of hearing. Psychiatric symptoms can manifest with the onset of neurosarcoidosis, result from CN deficits, or develop as a side effect from long-term, high-dose corticosteroids, and should be monitored carefully in patients with neurosarcoidosis.

RESUMO

The purpose of this retrospective study was to characterize and further define autoimmune inner ear disease (AIED) using the Harris AIED classification. A retrospective review was conducted at two tertiary medical centers for 47 patients who were diagnosed with AIED. The overall patient response rate to oral prednisone treatment was 69.7%. The sensitivity of the test for a serum antibody against heat-shock protein 70 (HSP70) was 54.5% and the specificity was 42.9%. Therefore, the clinical utility of the HSP70 antibody test appeared to be limited with respect to the diagnosis of AIED. Vertigo, tinnitus and aural fullness improved significantly with both of the newly developed adalimumab (Humira®) and rituximab (Rituxan®). However, hearing loss did not improve in the present study.

RESUMO

Importance: High surgical vestibular schwannoma case volume in a medical institution may decrease the risk of adverse outcomes among patients undergoing vestibular schwannoma surgery. Objective: To study the association between surgical vestibular schwannoma case volume and excess time in the hospital after vestibular schwannoma surgery. Design, Setting, and Participants: This cohort study evaluated data from the National Cancer Database from January 1, 2004, through December 31, 2019, on Commission on Cancer-accredited facilities in the US. The hospital-based sample comprised adult patients aged 18 years or older with a vestibular schwannoma treated with surgery. Exposures: Facility case volume, defined as the mean number of surgical vestibular schwannoma cases per year in the 2 years preceding the index case. Main Outcomes and Measures: The primary outcome was a composite of prolonged hospital stay (>90th percentile) or 30-day readmission. Risk-adjusted restricted cubic splines were used to model the probability of the outcome according to facility volume. The inflection point (in cases per year) when the declining risk of excess time in the hospital began to plateau was selected as the threshold to define high- and low-volume facilities. Outcomes were compared among patients treated at high- and low-volume facilities, with mixed-effects logistic regression models adjusting for patient sociodemographic characteristics, comorbidities, tumor size, and clustering within facilities. Collected data were analyzed between June 24 and August 31, 2022. Results: Among 11 524 eligible patients (mean [SD] age, 50.2 [12.8] years; 53.5% female; 46.5% male) who underwent surgical resection of vestibular schwannoma at 66 reporting facilities, the median length of stay was 4 (IQR, 3-5) days, and 655 patients (5.7%) were readmitted within 30 days. The median case volume was 16 (IQR, 9-26) cases per year. An adjusted restricted cubic spline model identified a downtrending probability of excess time in the hospital with increasing volume. The declining risk of excess time in the hospital began to plateau at a facility volume of 25 cases per year. Surgery at a facility with an annual case volume at or above this threshold was independently associated with a 42% reduction in the odds of excess time in the hospital compared with surgery at a low-volume center (odds ratio, 0.58; 95% CI, 0.44-0.77). Conclusions and Relevance: This cohort study found that among adults undergoing vestibular schwannoma surgery, a higher facility case volume was associated with a reduced risk of prolonged hospital stay or 30-day readmission. A facility case volume of 25 cases per year may represent a risk-defining threshold.

RESUMO

Objectives: This study aimed to evaluate the outcomes of a hands-on simulation-based course with emphasis on procedural techniques, clinical reasoning, and communication skills developed to improve junior Otolaryngology - Head and Neck Surgery (OHNS) residents' preparedness in managing otolaryngologic emergencies. Methods: Junior OHNS residents and faculty from residency programs in California, Nevada, and Arizona participated in this workshop in 2020 and 2021. The stations featured airway management techniques, ultrasound-guided needle aspiration, nasoseptal hematoma evacuation, and facial fracture repair using various models and cadavers. Participants completed a pre-workshop survey, post-workshop survey, and 2-month follow-up survey that assessed resident anxiety and confidence in three OHNS emergency situations across knowledge, manual skills, and teamwork using a 5-point Likert scale. Results: Pre-workshop surveys reported the least anxiety and most confidence in teamwork, but the most anxiety and least confidence in technical skills and knowledge related to foreign body retrieval and airway management. Immediately post-workshop participants reported significant reductions in anxiety and increases in confidence, largest in the manual skills domain, in foreign body retrieval (anxiety: -0.99, confidence: +0.95, p < .01) and airway management stations (anxiety: -0.68, confidence: +1.07, p < .01). Data collected for the epistaxis station showed decreasing confidence and increasing anxiety following the workshop. Conclusion: Our findings demonstrate the effectiveness of a workshop in preparing junior residents in potentially lifesaving otolaryngologic techniques that residents will encounter. Optimizing use of simulation centered training can inform the future of residency education, improving confidence and decreasing anxiety in residents responsible for the safety of patients. Level of Evidence: III.

RESUMO

Purpose of Review: This review briefly covers the history of stapedectomy, discusses the indications and problems encountered with revision surgery, and provides case examples with solutions. Recent Findings: Revision surgery is challenging and successful outcome even in the most experienced specialists is 45-71%, which is far less than that of primary surgery. Summary: Careful evaluation of the reasons for reoperation, anticipation of the common problems, and patient education on reasonable expectations are all very important for success.

RESUMO

OBJECTIVES/HYPOTHESIS: To better understand the obstacles facing residents and K-awardee faculty in choosing a clinician-scientist career in otolaryngology. STUDY DESIGN: Anonymous survey. METHODS: An anonymous, online Qualtrics survey was sent to residents participating in T32 training grants and K-awardee junior faculty. The survey was sent to the residents with the permission of their program chair. The results of this survey were compiled and analyzed. A separate survey was sent to current K-awardees in U.S. academic programs. Both surveys were then compared to a survey published in 2008 to determine if the concerns and obstacles faced by aspiring clinician-scientists are still present. RESULTS: Residents felt that combining a research and clinical career presented many obstacles, including a lower salary, competition with PhDs for grant funding, and the lack of departmental support. Prolonging their training to include a fellowship was not a deterrent. Family/spousal issues which ranked as the primary concern previously were no longer given the same level of importance. The major concerns of K-awardees were the economic disparity of clinician-scientists with their clinical counterparts, the lack of mentors, and department support. Forty percent received their K-award after first try, 100% after two revisions, and one has received an R grant funding. CONCLUSIONS: The obstacles facing clinician-scientists in otolaryngology are highlighted by this survey and require attention by our academic programs, National Institutes of Health, and specialty societies. LEVEL OF EVIDENCE: NA Laryngoscope, 132:1555-1560, 2022.

RESUMO

Objectives Dispersion of bone dust in the posterior fossa during retrosigmoid craniectomy for vestibular schwannoma (VS) resection could be a source of meningeal irritation and lead to development of persistent postoperative headaches (POH). We aim to determine risk factors, including whether the presence of bone spicules that influence POH after retrosigmoid VS resection. Design Present study is a retrospective case series. Setting The study was conducted at a tertiary skull-base referral center. Participants Adult patients undergoing VS resection via a retrosigmoid approach between November 2017 and February 2020 were included for this study. Main Outcome Measures Development of POH lasting ≥ 3 months is the primary outcome of this study. Results Of 64 patients undergoing surgery, 49 had complete data (mean age, 49 years; 53% female). Mean follow-up time was 2.4 years. At latest follow up, 16 (33%) had no headaches, 14 (29%) experienced headaches lasting <3 months, 19 (39%) reported POH lasting ≥3 months. Twenty-seven (55%) patients had posterior fossa bone spicules detectable on postoperative computed tomography (CT). Age, gender, body mass index, length of stay, tumor diameter, size of craniectomy, the presence of bone spicules, or the amount of posterior petrous temporal bone removed from drilling did not differ significantly between patients with POH and those without. On multivariate logistic regression, patients with POH were less likely to have preoperative brainstem compression by the tumor (odds ratio [OR] = 0.21, p = 0.028) and more likely to have higher opioid requirements during hospitalization (OR = 1.023, p = 0.045). Conclusion The presence of bone spicules in the posterior fossa on postoperative CT did not contribute to headaches following retrosigmoid craniectomy approach for VS resection.

RESUMO

Exostoses and osteomas are benign bony lesions of the auditory canal. Although common in the external auditory canal, they are rare and difficult to distinguish in the internal auditory canal (IAC). In this literature review and case presentation, we define radiologic and histologic criteria to differentiate exostoses from osteomas of the IAC. Two patients with exostoses and 1 patient with an osteoma of the IAC are described here. Patient 1 presented with disabling vertigo and was found to have bilateral exostoses with nerve impingement on the right. After removal of the right-sided exostoses via retrosigmoid craniotomy, the patient had complete resolution of her symptoms over 1 year. Patient 2 presented with bilateral pulsatile tinnitus and vertigo and was found to have bilateral IAC exostoses. Patient 3 presented with hearing loss and tinnitus, and a unilateral IAC osteoma was ultimately discovered. Because of the mild nature of their symptoms, patients 2 and 3 were managed without surgery. We show that IAC osteomas can be differentiated from exostoses by radiographic evidence of bone marrow in high-resolution computed tomography scans, or by the presence of fibrovascular channels on histologic analysis. Management of these rare entities is customized on the basis of patient symptoms.

RESUMO

CONTEXT: Idiopathic sudden sensorineural hearing loss has been treated with oral corticosteroids for more than 30 years. Recently, many patients' symptoms have been managed with intratympanic steroid therapy. No satisfactory comparative effectiveness study to support this practice exists. OBJECTIVE: To compare the effectiveness of oral vs intratympanic steroid to treat sudden sensorineural hearing loss. DESIGN, SETTING, AND PATIENTS: Prospective, randomized, noninferiority trial involving 250 patients with unilateral sensorineural hearing loss presenting within 14 days of onset of 50 dB or higher of pure tone average (PTA) hearing threshold. The study was conducted from December 2004 through October 2009 at 16 academic community-based otology practices. Participants were followed up for 6 months. INTERVENTION: One hundred twenty-one patients received either 60 mg/d of oral prednisone for 14 days with a 5-day taper and 129 patients received 4 doses over 14 days of 40 mg/mL of methylprednisolone injected into the middle ear. MAIN OUTCOME MEASURES: Primary end point was change in hearing at 2 months after treatment. Noninferiority was defined as less than a 10-dB difference in hearing outcome between treatments. RESULTS: In the oral prednisone group, PTA improved by 30.7 dB compared with a 28.7-dB improvement in the intratympanic treatment group. Mean pure tone average at 2 months was 56.0 for the oral steroid treatment group and 57.6 dB for the intratympanic treatment group. Recovery of hearing on oral treatment at 2 months by intention-to-treat analysis was 2.0 dB greater than intratympanic treatment (95.21% upper confidence interval, 6.6 dB). Per-protocol analysis confirmed the intention-to-treat result. Thus, the hypothesis of inferiority of intratympanic methylprednisolone to oral prednisone for primary treatment of sudden sensorineural hearing loss was rejected. CONCLUSION: Among patients with idiopathic sudden sensorineural hearing loss, hearing level 2 months after treatment showed that intratympanic treatment was not inferior to oral prednisone treatment. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00097448.

RESUMO

Previously reported prevalence rates of Ménière's syndrome (MS) have ranged from 3.5 per 100000 to 513 per 100000. Recent data regarding the prevalence in the United States are lacking. To further assess the current-day prevalence of MS in the US, data from a medical and pharmaceutical claims database containing information for over 60 million unique patients were analyzed. Patients in the database are representative of the national, commercially insured population on a variety of demographic measures including age, gender, health plan type, and geographic location. A 3-year period from 2005 to 2007 was analyzed. The prevalence of MS was 190 per 100000 with a female:male ratio of 1.89:1. The prevalence increased with increasing age, ranging from 9 per 100000 for patients under age 18 to 440 per 100000 for patients 65 years and older.

RESUMO

Importance: Otosclerosis can be managed through surgical treatment, such as stapedectomy, or through hearing amplification with hearing aids. To our knowledge, there has been no cost-effectiveness analysis of these 2 treatment methods. Objective: To determine the cost-effectiveness of stapedectomy vs hearing aid use for the treatment of otosclerosis. Design and Setting: In this cost-effectiveness analysis, a decision tree was built to model the treatment choices for otosclerosis. The tree was run as a Markov model of a case patient aged 30 years. The model spanned the patient's lifetime to determine total costs of management of otosclerosis with stapedectomy or hearing aids. Cost-effectiveness was measured using an incremental cost-effectiveness ratio, with a willingness to pay of $50 000 per quality-adjusted life-year (QALY) considered cost-effective. One-way sensitivity analyses were performed for all variables. A 2-way sensitivity analysis was performed for the cost of stapedectomy vs the cost of hearing aids. Probabilistic sensitivity analysis was performed to determine the likelihood that stapedectomy would be cost-effective across a range of model inputs. Interventions: Stapedectomy vs hearing aid use. Main Outcomes and Measures: The primary objective of this study was to determine the cost-effectiveness of stapedectomy vs hearing aids in the treatment of otosclerosis. The secondary objectives were to determine which factors are associated with the cost-effectiveness of the interventions. Results: Stapedectomy had an estimated lifetime cost of $19 417.95, while hearing aids had an average lifetime cost of $16 439.94. Stapedectomy also had a benefit of 16.58 QALYs, and hearing aids had a benefit of 15.82 QALYs. Stapedectomy increases lifetime costs by $2978.01, with a benefit of 0.76 QALYs compared with hearing aids. The incremental cost-effectiveness ratio for stapedectomy is $3918.43 per QALY. The model was sensitive to the cost of stapedectomy and the cost of stapedectomy revision surgery. Probabilistic sensitivity analysis showed that stapedectomy was cost-effective compared with hearing aids 99.98% of the time. Conclusions and Relevance: Stapedectomy appears to be a cost-effective option for treating otosclerosis compared with hearing aid use, from the patient perspective.

RESUMO

OBJECTIVE: We describe three rare cases of spontaneous intracranial hypotension (SIH) presenting with symptoms of endolymphatic hydrops (EH) and perform a literature review to bring attention to a rare link between SIH and EH. PATIENT: A 59-year-old female presented with postural headache, aural fullness, vertigo, hearing loss, and abnormal electrocochleography after being diagnosed with SIH by magnetic resonance imaging. The site of cerebrospinal fluid leak was identified in this individual. Two additional patients with vertigo, hearing loss, and SIH were identified by retrospective chart review. INTERVENTION: All patients underwent blood patches. One patient also had diuretic treatment while another had fibrin glue injection. MAIN OUTCOME MEASURES: The outcomes of interest were resolution of headache, vertigo, aural fullness, and hearing loss. RESULTS: All patients eventually improved with time. Literature review suggests that overall outcome is excellent. CONCLUSIONS: SIH may be an under-recognized cause of EH. We support the theory that negative intracranial pressure transmitted through the cochlear aqueduct and perilymph leads to EH. Despite the variations in treatments, the overall prognosis is excellent.

RESUMO

BACKGROUND: Hearing impairment is prevalent among older adults and has been identified as a risk factor for cognitive impairment and dementia. We evaluated the association of hearing impairment with long-term cognitive decline among community-dwelling older adults. METHODS: A population-based longitudinal study of adults not using hearing aids who had hearing acuity and cognitive function assessed in 1992-1996, and were followed for a maximum of 24 years with up to five additional cognitive assessments. Hearing acuity was categorized based on pure-tone average (PTA) thresholds: normal (PTA ≤ 25 dB), mild impairment (PTA > 25-40 dB), moderate/severe impairment (PTA > 40 dB). RESULTS: Of 1,164 participants (mean age 73.5 years, 64% women), 580 (49.8%) had mild hearing impairment and 196 (16.8%) had moderate/severe hearing impairment. In fully adjusted models, hearing impairment was associated with steeper decline on the Mini-Mental State Examination (MMSE) (mild impairment ß = -0.04, p = .01; moderate/severe impairment ß = -0.08, p = .002) and Trails B (mild impairment ß = 1.21, p = .003; moderate/severe impairment ß = 2.16, p = .003). Associations did not differ by sex or apolipoprotein E (APOE) ϵ4 status and were not influenced by social engagement. The MMSE-hearing association was modified by education: mild hearing impairment was associated with steeper decline on the MMSE among participants without college education but not among those with college education. Moderate/severe hearing impairment was associated with steeper MMSE decline regardless of education level. CONCLUSIONS: Hearing impairment is associated with accelerated cognitive decline with age, and should be screened for routinely. Higher education may provide sufficient cognitive reserve to counter effects of mild, but not more severe, hearing impairment.

RESUMO

The thermo-reversible triblock copolymer poloxamer 407 was investigated as a drug delivery vehicle for micronized dexamethasone into the middle and inner ears of guinea pigs. The study characterized the gelation and in vitro release kinetics of poloxamer formulations. In vivo, the pharmacokinetic profile of formulations containing varying concentrations of poloxamer and dexamethasone was examined following intratympanic administration. Significant drug levels within the perilymph were observed for at least 10 days, while systemic exposure was minimal. The sustained-release kinetics profile could be significantly modulated by varying the concentrations of both poloxamer and dexamethasone. Assessment of auditory function revealed a small transient shift in hearing threshold, most probably of conductive nature, which resolved itself within a week. No significant histological changes of the round window membrane or cochlea could be noted. Poloxamer 407 thus represents an effective and safe delivery system to achieve sustained release of dexamethasone to the inner ear.

RESUMO

OBJECTIVE: AIED (autoimmune inner ear disease) is an autoimmune process that leads to the dysfunction of the inner ear, resulting in fluctuating, audiovestibular symptoms. Although the pathogenesis is likely heterogeneous, immune processes within the inner ear ultimately lead to histopathologic changes and sensorineural hearing loss. This review will discuss the latest evidence on treatment options. METHODS: A literature search on articles pertaining to the treatment of autoimmune inner ear disease was performed on PubMed. RESULTS: Corticosteroid treatment continues to remain as first line therapy for AIED but long-term responsiveness is poor. Cytotoxic chemotherapies can be effective alternatives for steroid nonresponsive patients, but significant side effects may limit their use. Intratympanic steroid injections are beneficial and although there is not enough evidence currently to supplant oral steroid trial they may be a useful adjunct if steroid toxicity is an issue. The efficacy of biologic agents has been variable. Compared to placebo, etanercept does not improve the hearing improvement already attained by steroids alone. However, open pilot studies of other biologic agents show hearing improvements, improvements in tinnitus/aural fullness/vertigo, ability to wean steroid dependency, or benefits in steroid-resistant AIED. CONCLUSION: There is currently not enough evidence that alternative treatments supersede the use of initial steroid treatment. Biologic agents and intratympanic steroid injections are relatively well tolerated and should be considered as adjunctive therapy. More studies on the efficacy of various biologics and more studies on the treatment of steroid resistant disease especially after initial benefit are still needed. For those who eventually lose their hearing, cochlear implantation remains as a viable option. LEVEL OF EVIDENCE: expert opinion.

RESUMO

OBJECTIVE: Otogenic brain abscess is a well-recognized clinical condition that describes brain abscess secondary to an ear infection or mastoiditis. Current evidence remains limited on risk factors associated with mortality as most data are from case series. We aimed to 1) report the mortality rate among patients who did and did not receive mastoidectomy 2) identify factors associated with inpatient mortality. STUDY DESIGN: Retrospective cohort study. SETTING: Multi-institutional. PATIENTS: We identified a cohort of patients for years 2008 to 2014 who in their inpatient hospitalization carried the diagnoses of both brain abscess and infectious ear disease. INTERVENTIONS: Inpatient neurotology and neurosurgical procedures. MAIN OUTCOME MEASURES: A multivariable logistics regression model was built to identify the factors associated with inpatient mortality. RESULTS: The final analysis included 252 patients, of which 84 (33.3%) underwent mastoidectomy. The rate of inpatient morbidity and mortality were 17.5% and 4.0%, respectively. The rate of mortality in patients without mastoidectomy versus those with mastoidectomy was 4.2% versus 3.6%, respectively (p > 0.99). The odds of inpatient mortality were significantly increased for every 10-year increase in age (odds ratio [OR] 2.73, 95% confidence interval [CI]: 1.39-7.01, p = 0.011) and for Black compared to White patients (OR: 45.81, 95% CI: 4.56-890.92, p = 0.003). CONCLUSION: Older age and Black race were associated with increased odds of inpatient mortality and there were no significant differences in mortality between mastoidectomy cohorts. This research serves to generate further hypotheses for larger observational studies to investigate the association between sociodemographic factors and surgical variables with outcomes among this surgical population.

RESUMO

OBJECTIVE: To understand the reasons for the decrease in clinician-scientists in otolaryngology. STUDY DESIGN: An anonymous survey was prepared that questioned career preparation and personal demographics as well as motive for having done research in medical school. K awardees were also asked for concerns in choosing the clinician-scientist career path and the obstacles encountered. SUBJECTS AND METHODS: A survey was conducted of the 2005 National Institute of Deafness and Other Communication Disorders otolaryngologist K-awardees and otolaryngology residents from three research-oriented U.S. medical schools. RESULTS: Residents felt that family issues ranked as a primary concern, followed by the time factor necessary to devote to research that would detract from their family and personal life. The K-awardees' concern also appeared to be family issues; the lack of departmental support ranked second. The K-awardees expressed that protected research time, a mentor, and departmental support were important to success. CONCLUSION: This survey found that although young otolaryngologists are interested in research, they are deterred by financial and family constraints and a perceived paucity of departmental support.
