Brief Summary:
The aim of this study is to assess effect of psychiatric profile on visual sensitivity and overall health status in patients who underwent surgery for vestibular schwannoma and were prehabituated by chemical vestibular ablation.

Condition or disease Intervention/treatment Phase
Vestibular Schwannoma Vestibular Function Disorder Procedure: intratympanic application of gentamicin Procedure: microsurgical removal of vestibular schwannoma Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 37 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: two groups of patients, one group prehabituated by chemical labyrintectomy, the second control group without prehabituation before the surgery
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Assessment of Visual Sensitivity, Psychiatric Profile and Quality of Life Following Vestibular Schwannoma Surgery in Patients Prehabituated by Chemical Vestibular Ablation
Actual Study Start Date : January 1, 2016
Actual Primary Completion Date : June 1, 2018
Actual Study Completion Date : June 1, 2018

Arm Intervention/treatment
Experimental: ITG (intratympanic gentamicin) group
Patients who underwent prehabituation by gentamicin prior to surgery for vestibular schwannoma. They underwent intratympanic application of gentamicin and microsurgical removal of vest. schwannoma.
Procedure: intratympanic application of gentamicin
under local anesthesia is gentamicin instilled through tympanic membrane to tympanic cavity

Procedure: microsurgical removal of vestibular schwannoma
surgery under general anesthesia

Active Comparator: control group
patients without prehabituation before surgery. They underwent microsurgical removal of vest. schwannoma.
Procedure: microsurgical removal of vestibular schwannoma
surgery under general anesthesia

Primary Outcome Measures :
  1. change of optokinetic nystagmus measurement [ Time Frame: change of the gain of optokinetic nystagmus among 3 time points is measured: before intervention, 1 week after intervention, 3 months after intervention ]
    During electronystagmography gain of optokinetic nystagmus is measured before and after the intervention
