Summary
Brief summary (as posted)
The purpose of the study is to determine whether vestibular and postural compensation following schwannoma surgery is improved by ablating vestibular function prior to surgery, even if vestibular function is absent according to modern assessment techniques

- EXPERIMENTAL
- label
- Gentamicin treated
- description
- Installation of gentamicin in the middle ear 6 weeks prior to surgery + rehabilitation exercises before and after both treatment and surgery. Rehabilitation exercises are not considered to be an intervention since their benign impact on vestibular/postural compensation is well documented and exclusion from exercises would not be approved by the ethical board

Inclusion Criteria: * Vestibular schwannoma advised to surgical treatment * No measurable remaining vestibular function Exclusion Criteria: * impaired decision making * neurofibromatosis * signs for central dysfunction * remaining vestibular function * Patients are advised not to participate in the gentamicin arm if * hearing is better than 30 deciBel (dB) in pure tone average (500, 1000, 2000, 3-4000 Hz) and speech discrimination better than 70% * the neurosurgeon aim at hearing preservation surgery and do not want to risk gentamicin associated hearing loss
