Vestibular Evaluation Before and After Treatment of Vestibular Schwannoma. Comparison of Gamma Knife Radiosurgery and Microsurgical Resection

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.
