OBJECTIVE: Tophaceous lesions of the middle ear from calcium pyrophosphate deposition disease (CPPD, or pseudogout) and gout are infrequently reported. Recognizing its characteristic findings will allow clinicians to accurately narrow the differential diagnosis of bony-appearing middle ear lesions and improve management. PATIENTS: Two consecutive cases of tophaceous middle ear lesions presenting to a tertiary care center between January 2021 and December 2021. Neither with previous rheumatologic history...

INTRODUCTION: Preservation of residual hearing after cochlear implantation allows for electroacoustic stimulation, which leads to better music appreciation, noise localization, and speech comprehension in noisy environments. Real-time intraoperative electrocochleography (rt-ECochG) monitoring has shown promise in improving residual hearing rates. Four-point impedance (4PI) is being explored as a potential biomarker in cochlear implantation that has been associated with fibrotic tissue response, hearing loss, and dizziness...

OBJECTIVE: This study focused on the intensities of cochlear implant (CI) stimulation in pediatric CI users with inner ear malformation or cochlear nerve deficiency (CND). In this population, CI programming is difficult because a large intensity of CI stimulation is required to achieve sufficient hearing, but the excess CI stimuli often induce facial nerve stimulation. We aimed to assess whether the results of intraoperative electrically evoked auditory brainstem responses (EABRs) testing predict maximum current levels of CI stimuli (cC levels) optimized by a behavioral-based method after long-term CI use...

OBJECTIVE: To determine the utility of computed tomography (CT) and magnetic resonance imaging (MRI) in cochlear implant candidates. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral hospital. PATIENTS: A total of 207 cochlear implanted patients with CT and/or MRI. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Age versus abnormal radiologic findings, imaging abnormality versus postoperative outcomes, postoperative outcomes versus electrode design, Cambridge Cochlear Implant Protocol (CCIP) status for imaging abnormalities, sensitivity and specificity of CT and MRI for round-window/cochlear occlusion, and MRI for incomplete partitions...

OBJECTIVE: To assess cochlear implant (CI) sound processor usage over time in children with single-sided deafness (SSD) and identify factors influencing device use. STUDY DESIGN: Retrospective, chart review study. SETTING: Pediatric tertiary referral center. PATIENTS: Children with SSD who received CI between 2014 and 2020. OUTCOME MEASURE: Primary outcome was average daily CI sound processor usage over follow-up...

OBJECTIVES: Barochallenge-induced Eustachian tube dysfunction (ETD) is difficult to diagnose because the examination is often normal during clinical assessment. In adults, functional tympanometry testing, performed by asking the patient to Valsalva and Toynbee while measuring the pressure shift, can aid in the diagnosis of ETD. However, standardized values do not exist in children. We aim to determine the age at which children can perform these maneuvers and the normative values in this population...

OBJECTIVE: Comparison of outcomes of microscopic and endoscopic resection of glomus tympanicum (GT) tumors. STUDY DESIGN: Retrospective case review. SETTING: Single tertiary referral center. PATIENTS: All adult patients undergoing transcanal GT resection without mastoidectomy from 2007 to 2021. INTERVENTIONS: Surgical resection-endoscopic versus microscopic approach. MAIN OUTCOME MEASURES: Primary outcomes were tumor recurrence at 1 year and presence of residual tumor at conclusion of surgery...

OBJECTIVE: This study aims to analyze the impact of age and other prognostic factors on the success of myringoplasty. STUDY DESIGN: A retrospective case series. SETTINGS: Pediatric ENT department of a tertiary academic center. PATIENTS: Two hundred forty-one children (318 ears) aged 3 to 17 years with tympanic perforation. INTERVENTION: Myringoplasty performed between 2009 and 2019. MAIN OUTCOMES MEASURES: The rate of tympanic closure, perforation recurrence, revision surgery, and audiometric gain were collected...

OBJECTIVE: To make recommendations for evaluation, approach to counseling and treatment for patients who present with ear fullness without abnormalities on otomicroscopic examination, standard audiometric studies, or imaging results. METHODS: Retrospective chart review of adult patients in a tertiary referral center presenting with ear fullness and/or otalgia without external, middle, and/or inner ear pathologies. Data collected include demographics (age and gender), laterality and duration of symptoms, co-morbid conditions and final diagnoses of temporomandibular joint (TMJ) dysfunction, intermittent Eustachian tube dysfunction (iETD), migraine disorder, and anxiety...

OBJECTIVE: Intralabyrinthine schwannomas (ILSs) are a rare cause of deafness. Patients with ILS confined to the semicircular canals and the vestibule (intravestibular schwannomas) are potential candidates for cochlear implantation for hearing rehabilitation, a new option for patients with unilateral hearing loss since the 2019 FDA approval of cochlear implant (CI) for single-sided deafness. In this report, we describe an evolving management approach for ILSs causing hearing loss. PATIENTS: Adults (≥18 years) who underwent simultaneous ILS resection and CI between January 2019 and June 2023 (n = 3)...

OBJECTIVE: To quantify the placebo effect in randomized clinical trials treating tinnitus with oral or intratympanic placebo treatment. DATA SOURCES: CINAHL, PubMed, and Scopus were searched for articles from conception to October 2022. MESH and key terms such as "tinnitus," "placebo," and "medication" were used to find randomized, placebo-controlled trials. The search was limited to articles in English. METHODS: Randomized controlled trials with adult subjects evaluating tinnitus pretreatment and posttreatment with an oral or intratympanic medication versus a placebo arm were included...

OBJECTIVE: To examine the role of lumbar drains (LDs) in the success of spontaneous temporal cerebrospinal fluid (CSF) leak and encephalocele repair. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic health system. PATIENTS: Patients undergoing repair of spontaneous temporal lobe encephaloceles or middle fossa CSF leaks during years 2017 to 2023. INTERVENTIONS: Transmastoid, middle fossa craniotomy, or combination approaches to CSF leak repair...

OBJECTIVE: Tympanic membrane (TM) thickness is an important parameter for differentiation between a healthy and a pathologic TM. Furthermore, it is needed for modeling the middle ear function. Endoscopic optical coherence tomography (eOCT) provides the opportunity to measure the TM thickness of the entire TM in vivo. MATERIALS AND METHODS: A total of 27 healthy ears were examined by eOCT. The system uses a light source with a central wavelength of 1,300 nm. The endoscope with an outer diameter of 3...

INTRODUCTION: Electrically evoked compound action potentials (ECAPs) are used for intra-/postoperative monitoring with intracochlear stimulation of cochlear implants. ECAPs are recorded in MED-EL (Innsbruck, Austria) implants using auditory response telemetry (ART), which has been further developed with automatic threshold determination as AutoART. The success of an ECAP measurement also depends on the number of available spiral ganglion cells and the bipolar neurons of the cochlear nerve (CN)...
