Complications of microvascular decompression surgery for hemifacial spasm: A review of 30 operated cases

Dr Amey P Patankar

Introduction: Microvascular decompression is the gold standard for the treatment of hemifacial spasm. However, this technique is technically demanding, with a steep learning curve and a propensity for complications during the early phase.We review our complications in a series of 30 patients operated in the last seven years

Materials and methods: Records of thirty patients operated in the last seven years were reviewed. The early and late complications were noted and the treatment given for the complications and the outcome was noted Results: Delayed facial palsy was the most common complication, occurring in three patients, followed by mild early facial palsy in one. Mild sensorineural hearing loss in one, delayed resolution of the spasms in two and recurrence of spasm in one patient was noted.

Conclusion: Microvascular decompression for hemifacial spasm is a safe procedure with a very low rate of complications which recover in a short time.
