No actionable change for audiologists; this surgical neurology study is relevant to neurosurgeons managing recurrent hemifacial spasm and has minimal direct bearing on audiology practice.
Understanding failure modes of microvascular decompression helps multidisciplinary teams—including audiologists who sometimes monitor intraoperative facial nerve function—set realistic patient expectations and support surgical planning.
- 01Systematically analyzed causes of recurrent or failed hemifacial spasm following microvascular decompression (MVD).
- 02Evaluated safety and efficacy of reoperative surgical strategies for MVD failures.
- 03Published in Neurosurgery Reviews 2026, indicating peer-reviewed, specialty-level evidence.
- 04Findings may inform intraoperative neurophysiological monitoring protocols relevant to audiology.
- 05Recurrence after MVD represents a clinically challenging subset of hemifacial spasm cases.
Reoperative strategies for recurrent or failed hemifacial spasm after MVD can be both safe and efficacious.
