Summary

Retrolabyrinthine vestibular neurectomy effectively cures vertigo while preserving hearing. This surgical approach is preferred for its ease, speed, and reduced risk to the facial nerve compared to the middle fossa method.

Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Vestibular System Disorders

Background:

  • Vestibular neurectomy is a surgical option for managing vertigo.
  • Preserving hearing during vestibular neurectomy is a key surgical goal.
  • Different surgical approaches exist, including middle fossa and retrolabyrinthine routes.

Purpose of the Study:

  • To evaluate the efficacy and safety of the retrolabyrinthine approach for vestibular neurectomy.
  • To compare the retrolabyrinthine approach with the middle fossa approach regarding surgical outcomes and risks.

Main Methods:

  • Retrolabyrinthine vestibular neurectomy was performed on 26 patients.
  • Patients were followed for 6 to 26 months post-surgery.
  • Outcomes assessed included vertigo cure rate and hearing preservation.

Main Results:

  • An 85% cure rate for vertigo was achieved (22/26 patients).
  • Hearing was unchanged or improved in 79% of patients (21/26).
  • The retrolabyrinthine approach was considered easier, faster, and safer for the facial nerve.

Conclusions:

  • Retrolabyrinthine vestibular neurectomy is an effective procedure for treating vertigo.
  • This approach offers a favorable balance of vertigo control and hearing preservation.
  • The retrolabyrinthine route presents advantages over the middle fossa approach in terms of surgical execution and safety.
