How I treat a square face with botulinum toxin A

FWY Ho 何榮潤

Injection of botulinum toxin A as a new form of treatment for square face in Oriental patients has created a lot of interest recently. In the past, treatment of square face involved major surgery in the form of mandibulectomy and muscle resection. Operation risk and morbidity are considerable and recurrence rate is high. Injection method is simple and safe. After a loading dose of the toxin, cosmetic result is almost immediate. Further injection at intervals is needed to maintain the result. Long lasting result is possible through subsequent bony remodelling.
