Summary

Transmastoid labyrinthectomy significantly improved dizziness handicap compared to vestibular neurectomy. Age and preoperative vestibular function also impact recovery after vestibular ablative procedures.

Area of Science:

  • Otolaryngology
  • Neurology
  • Vestibular Rehabilitation

Background:

  • Vestibular ablative procedures are performed to treat severe vertigo and dizziness.
  • Assessing post-procedural outcomes is crucial for patient management and surgical technique refinement.

Purpose of the Study:

  • To compare dizziness handicap and postural recovery between selective vestibular neurectomy and transmastoid labyrinthectomy.
  • To identify factors influencing recovery after vestibular ablative surgery.

Main Methods:

  • A cohort of 17 patients undergoing vestibular ablative procedures were assessed.
  • Patients completed the Dizziness Handicap Inventory (DHI) and underwent posturography (Sensory Organization Test [SOT]) pre- and post-operatively.
  • Outcomes were compared between nine patients who had vestibular neurectomy and eight who had transmastoid labyrinthectomy.

Main Results:

  • The labyrinthectomy group showed significant improvement in total DHI scores, while the neurectomy group only improved in the emotional subscale.
  • No significant differences in SOT scores were observed between pre- and post-procedure assessments for either group.
  • Age and preoperative vestibular SOT scores were significant predictors of post-procedural dizziness handicap, with younger patients and those undergoing neurectomy reporting more persistent dizziness.

Conclusions:

  • Transmastoid labyrinthectomy appears more effective in reducing overall dizziness handicap compared to selective vestibular neurectomy.
  • Preoperative vestibular function, assessed by SOT, is a strong predictor of perceived handicap and quality of life post-surgery.
  • Patient age is also a significant factor influencing recovery and persistent dizziness after vestibular ablative procedures.
