Barriers to auditory brainstem response testing under anesthesia.

Objective: Auditory brainstem response (ABR) testing is the gold standard for diagnosis of hearing loss in children who cannot complete behavioral audiometry. Testing under general anesthesia is often recommended when natural sleep ABR and/or behavioral audiometry are unsuccessful. This study aims to determine which demographic and patient factors serve as barriers to receiving this diagnostic testing.

In-office Transoral Hilar Sialolithotomy: A Cost-Effective and Patient-Centered Procedure.

Transoral sialolithotomy performed in-office under local anesthesia is routinely performed for distal submandibular stones. We demonstrate the senior author's novel practice of in-office transoral sialolithotomy for hilar and intraglandular stones. A review of cases performed by the senior author revealed similar rates of complication and stone recurrence as those reported in the literature from removal under general anesthesia.

Four distinct ipsilateral vestibular schwannomas: A case of mosaic NF2-related schwannomatosis.

Objectives: Distinguishing between sporadic and germline/mosaic NF2-related schwannomatosis is important to ensure that patients have appropriate long-term care. With this report, we describe a unique case of a patient with 4 ipsilateral schwannomas and identify a combination of sequencing modalities that can accurately diagnose mosaic NF2-related schwannomatosis.

Methods: We present a 32-year-old woman with a familial history of vestibular schwannoma in her father and right-sided schwannomas involving the apical and basal turns of cochlea, lateral semicircular canal, and internal auditory canal (IAC).

Confirmatory Auditory Brainstem Responses Testing Results in Discordant Outcomes: Implications for Timely Care.

Objectives: The purpose of this study is to evaluate for discrepancies in diagnostic auditory brainstem responses (ABR) between Children's National Hospital (CNH), a pediatric medical center, and outside facilities (OSF) that referred patients to CNH for confirmatory evaluation. Such discrepancies impact early hearing detection and intervention (EHDI) timelines.

Methods: A retrospective chart review was conducted from an internal database of patients who underwent diagnostic ABR from 2017 to 2021.

Flat Panel Computed Tomography in the Diagnosis of Superior Semicircular Canal Dehiscence Syndrome.

Hypothesis: Flat panel computed tomography (FPCT) provides more accurate measurements of dimensions for superior semicircular canal dehiscence (SCD) than multislice CT (MSCT).

Background: SCD syndrome occurs when a bony defect of the superior semicircular canal causes vestibular and auditory symptoms. MSCT can overestimate the size of the canal defect, with possible over-diagnosis of SCD and suboptimal selection of surgical approach.
