Summary
Retrolabyrinthine vestibular neurectomy effectively controls vertigo spells. This procedure preserves hearing in most patients and has a low complication rate, offering a safe treatment option.
Area of Science:
- Neurosurgery
- Otolaryngology
Background:
- Vestibular neurectomy is a surgical treatment for vertigo.
- Long-term outcomes regarding hearing preservation and vertigo recurrence are crucial.
Purpose of the Study:
- To evaluate the long-term hearing preservation and freedom from vertigo spells after retrolabyrinthine vestibular neurectomy.
Main Methods:
- Retrospective analysis of 34 patients undergoing vestibular neurectomy (Sept 1984 - Jan 1989).
- Focus on 15 patients with minimum 2-year follow-up, assessing audiograms and vertigo spells.
- Postoperative ice-caloric testing evaluated vestibular function.
Main Results:
- 73% of patients maintained hearing and speech discrimination scores at 12-40 months post-surgery.
- Significant hearing improvement in 5 patients; minor losses in 2.
- 25 patients had no vestibular response post-surgery; 6 had reduced responses. No major complications or facial paralysis.
Conclusions:
- Retrolabyrinthine vestibular neurectomy is effective for vertigo control.
- The procedure demonstrates good long-term hearing preservation.
- It offers an acceptably low incidence of complications and side effects.
