Summary
Retrolabyrinthine vestibular neurectomy can relieve vertigo but requires modification for prior canal-wall-down procedures. The retrosigmoid approach offers a safe alternative, preserving hearing and avoiding mastoid cavity contamination.
Area of Science:
- Otolaryngology
- Neurosurgery
- Vestibular Disorders
Background:
- Retrolabyrinthine vestibular neurectomy is effective for intractable vertigo.
- Prior canal-wall-down mastoid procedures complicate this approach due to contamination risks.
Observation:
- Three patients with prior canal-wall-down procedures and persistent vertigo underwent vestibular neurectomy.
- The retrosigmoid approach was utilized in these cases.
Findings:
- The retrosigmoid approach successfully sectioned the vestibular nerve.
- Hearing was preserved, and bacterial contamination of the subarachnoid space was avoided.
Implications:
- The retrosigmoid approach is a recommended alternative for vestibular neurectomy in patients with prior canal-wall-down procedures.
- This technique is suitable for patients with intractable vertigo, serviceable hearing, and exteriorized mastoid cavities.
