Summary
Vestibular neurectomy effectively controlled vertigo in 88% of patients with severe, intractable symptoms. This surgical option, particularly retrosigmoid vestibular nerve section, offers significant patient satisfaction and preserves hearing in most cases.
Area of Science:
- Neurosurgery
- Otolaryngology
- Vestibular Disorders
Background:
- Vestibular neurectomy, introduced in Denmark, leverages experiences from vestibular schwannoma surgery.
- This study reviews surgical interventions for intractable vertigo unresponsive to conventional treatments.
Purpose of the Study:
- To evaluate the efficacy and safety of vestibular nerve section (translabyrinthine, retrolabyrinthine, retrosigmoid) for severe vertigo.
- To assess patient satisfaction and hearing preservation following the procedure.
Main Methods:
- A retrospective analysis of 43 vestibular nerve sections performed between 1980 and 1996 on 42 patients.
- Patients had severe vertigo refractory to prior treatments; mean age 51, mean follow-up 6.4 years.
Main Results:
- Vertigo control achieved in 88% of patients.
- Postoperative imbalance occurred in 14 patients; 39 patients reported satisfaction.
- Hearing preservation was high (92% in pre-operatively hearing patients); complications were minimal.
Conclusions:
- Retrosigmoid vestibular nerve section is an effective treatment for refractory vertigo.
- Patient education regarding efficacy and risks is crucial; centralization of treatment is recommended due to the small patient cohort and need for surgical expertise.
