Synkinesis of Facial Musculature in a Patient with Facial Paralysis

Facial Synkinesis is a clinical condition that is the sequel to facial nerve paralysis which develops during nerve repair like axon myelination and regeneration. Involuntary muscle activity is accompanied by voluntary muscle activity and may involve facial and extra ocular muscles. This article describes an uncommon variation of facial Synkinesis that manifested clinically in weak voluntary chewing and frequent cheek biting in the form of mucosal erosion on the buccal mucosa. Managing a case of facial paralysis that has associated facial Synkinesis has also been discussed.
