About

Vestibular schwannoma is a benign tumor located on the vestibular nerve. Patient could present dizziness symptoms cause to the tumor, and at least after the treatment by gamaknife radiosurgery or microsurgery resection.

Only few studies keep the interest about dizziness symptoms and treatment modality in vestibular schwannoma.

In the study dizziness symptoms were compared before and after the treatment of vestibular schwannoma by radiosurgery gammaknife or microsurgery resection. 2 scales were used : dizziness handicap inventory (DHI) and dizziness functionnal scale (AAO).
