@entity1649 ( @entity1649 ) is a disorder characterized by unilateral involuntary @entity2473 of the muscles innervated by the facial nerve (cranial nerve VII). The etiology is often a redundant or ectatic artery in the cerebellopontine angle that compresses the facial nerve. Neurosurgical decompression with implantation of a sponge between the ectatic artery and the facial nerve produces good results, but has a high complication rate and a poor @entity1 acceptance rate. Various modes of peripheral neurectomy have also been advocated, but the recurrence rate is high and the preexisting functional and cosmetic eyelid deformities are exacerbated. The results of unilateral periorbital myectomy in 21 @entity1649 @entity1 are presented. Follow-up ranging from 1 to 7 years was available on 16 @entity1 . Excellent or good results were obtained in 94% of these cases, and @entity260 were minor. Transient @entity4269 and forehead anesthesia are the most common complications. An unforseen benefit of periorbital myectomy surgery is the improvement or relief of lower facial contractions that occurred in 75% of @entity1 . The authors believe the myectomy procedure is a safe, effective, predictable therapy for those @entity1649 @entity1 unwilling to risk a neurosurgical operation, and allows simultaneous reconstruction of associated eyelid and @entity85 .
