Objective: To evaluate cochlear implant speech perception among patients with sporadic inner ear schwannoma who underwent ipsilateral implantation.
Study Design: Retrospective multi-institutional cohort study.
Setting: Eleven tertiary academic medical centers across Germany, Denmark, and the United States.
This article describes the surgical treatment of superior semicircular canal dehiscence syndrome (SCDS) by isolating the dehiscence using transmastoid two-point canal plugging while preserving the high-frequency vestibulo-ocular reflex (VOR) of the affected semicircular canal. The superior semicircular canal is opened via a transmastoid approach anterior (as far from the ampulla as possible) and posterior to the dehiscence and then plugged with connective tissue and bone dust. In two clinical exemplary cases, vestibular testing showed that the VOR measured by video head impulse (vHIT) test was preserved (patient 1: gain preoperative 0.

Article Synopsis
- - This study compares cochlear implant (CI) outcomes for speech perception in patients with sporadic vestibular schwannoma (VS) treated through observation, radiosurgery, or microsurgery.
- - Of the 100 patients analyzed, those who underwent microsurgery had poorer speech perception scores compared to those who were observed or treated with radiosurgery, with only 61% achieving open-set speech perception after microsurgery.
- - The findings suggest that cochlear implants can be beneficial for sporadic VS patients, particularly those managed by observation or radiosurgery, as these groups showed significantly better outcomes in achieving open-set speech perception.
Article Synopsis
- This study focused on using vestibular evoked myogenic potentials (VEMPs) to evaluate otolith function in patients with unilateral vestibular schwannoma before surgery, measuring specific metrics like amplitudes, latencies, and threshold levels.
- Out of 27 participants, cVEMP was obtained from 89% and oVEMP from 74%, showing significant differences in cVEMP amplitudes and thresholds in patients with inferior vestibular nerve origin.
- The findings indicated increased p13 latency in the affected ear, but overall, the small sample size limited the ability for robust statistical conclusions, making the results exploratory in nature.
