ROLE OF VESTIBULAR EVOKED MYOGENIC POTENTIALS (VEMP) IN
PREDICTING THE OUTCOME OF STAPEDOTOMY- A PROSPECTIVE
OBSERVATIONAL STUDY
Vestibular evoked myogenic potentials (VEMP) is an objective and non-invasive measure of saccule function that primarily respond to linear acceleration in any direction. Stapedotomy is a procedure done for otosclerosis to improve hearing. The aim of this study was to correlate the VEMPresults with pure tone audiogram pre- and post- stapedotomy in otosclerotic patients. Aprospective observational study was conducted from 2017-2020 in a tertiary care hospital of south India. Patients who underwent stapedotomy for otosclerosis and satised the study criteria were included. Atotal of 22 patients were included in the study. All patients underwent pure tone audiogram (PTA) and VEMP preoperatively and postoperatively. The results were compared and analysed. The mean pre-operative and post-operative ABG were 26.32±9.36 dB and 18.10 ±8.06 dB respectively. (P=0.001). There was no signicant change in VEMP positivity rates, latency and amplitude. The results showed that there was no correlation between the PTAvalues and VEMPpositivity rate in otosclerotic patients. The VEMPpositivity rate was also not affected signicantly by stapedotomy. Based on above ndings we conclude that stapedotomy is a safe and effective procedure with no signicant inner ear trauma.
