Surgical repair for congenital macrostomia: vermilion square flap method.

Abstract

Congenital macrostomia (transverse facial cleft) is a relatively rare anomaly. Surgical methods used to correct this anomaly include commissuroplasty, muscle-plasty of the orbicularis oris, and closure of the cleft cheek. The authors report a new vermilion square flap surgical technique that combines a lower lip mucocutaneous vermilion border flap with a lazy W-plasty to ensure a natural commissure and cheek skin closure. This technique was used in 8 patients with satisfactory results.
