Surgical labyrinthectomy and vestibular neurectomy effectively control vertigo. Vestibular neurectomy offers hearing preservation but has higher complication risks than labyrinthectomy, with long-term hearing benefits uncertain.
Area of Science:
- Otolaryngology
- Neurosurgery
- Vestibular Disorders
Background:
- Incapacitating vertigo often requires surgical intervention when medical treatments fail.
- Labyrinthectomy and vestibular neurectomy are primary surgical options for intractable vertigo.
- Decision-making between these procedures historically hinges on hearing status and surgical risks.
Purpose of the Study:
- To review and compare surgical labyrinthectomy and vestibular neurectomy for treating severe vestibular disorders.
- To evaluate the efficacy and safety profiles of these surgical interventions.
- To contrast surgical approaches with chemical labyrinthectomy.
Main Methods:
- Comprehensive literature review of PubMed, MD Consult, and Ovid-SP databases.
- Analysis of candidate selection, vertigo control success rates, and complication data.
- Comparison of transmastoid labyrinthectomy, vestibular neurectomy, and chemical labyrinthectomy.
Main Results:
- Both vestibular nerve section and labyrinthectomy demonstrate high and comparable vertigo control rates.
- Vestibular neurectomy, an intradural procedure, carries higher complication risks than transmastoid labyrinthectomy.
- Long-term hearing preservation with vestibular nerve section is not consistently established.
Conclusions:
- Vestibular neurectomy and labyrinthectomy are effective for vertigo management, with differing risk profiles.
- Transmastoid labyrinthectomy may be preferred to minimize intracranial complications.
- Chemical labyrinthectomy presents an alternative but carries significant risks of hearing loss.
