Intraoperative EABR for Decision Making

November 21, 2024 updated by: Christoph Arnoldner

Simultaneous Translabyrinthine Surgery of Vestibular Schwannoma and Cochlear Implantation with Intraoperative EBERA and Correlation to Hearing Results - a Pilot Study

In this study patients undergoing simultaneous translabyrinthine vestibular schwannoma resection and cochlear implantation are included. The goal of the study is to correlate the eABR results with postoperative hearing results.

Detailed Description

Patients undergoing translabyrinthine vestibular schwannoma resection are included in the study. Preoperatively an eABR is carried out, as well as before and after tumor resection.

Postoperatively patients are fitted with a cochlear implant as routinely carried out. The postoperative hearing results with cochlear implant are correlated to the eABR results. The study is an observational study since eABR measurements are not part of the study. A correlation between eABR results categorized in three groups (good response, weak response, no response) with monosyllable understanding with cochlear implant (measured with Freiburger monosyllables test).

Measure Description
Time Frame
Correlation of eABR results to postoperative hearing results
Time Frame: 2 years

eABR is correlated with postoperative hearing results eABR will be divided in three categories - good response, weak response, no response.

Hearing results will be measured with speech understanding in Freiburg monosyllables word test which is measured in % of monosyllables understanding at 65 and 80dB
