Study Overview
=================
Brief Summary
-----------------
The surgery of a vestibular schwannoma induces balance disorders which have a an impact on the patient's daily life and disrupt their quality of life. But the balance disorders don't seem to be the only ones factors that impaired the patient's quality of life. It has been alrealdy shown that emotional and psychological factors are also related to patient's quality of life. This study evaluates the relationship between the balance control compensation and these factors (i.e. emotional and psychological) in the vestibular schwannoma resection process.

Detailed Description
-----------------
The research protocol is based on 5 evaluation: 3 days before surgery, 8 days, 30 days, 90 days and 360 days after surgery including posturographic tests, videonystagmography and psychological questionnaires at each evaluation.
