How I do it: microvascular decompression for hemifacial spasm using an inferior ventrolateral brainstem approach

Hemifacial spasm is commonly caused by a vascular compression of the facial nerve at its root exit zone (REZ), at brainstem. Microvascular decompression provides long-term cure in approximately 90% of the patients (delayed in one-third). Based on more than three hundred procedures, the authors advocate an inferior ventro-lateral brainstem approach....

No actionable change for audiologists; this is a neurosurgical technique paper with minimal direct relevance to audiology clinical practice, though auditory monitoring is sometimes involved in such procedures.

Refined surgical techniques for microvascular decompression can reduce complication rates including hearing loss, which is a known risk of posterior fossa surgery relevant to the audiology community.
