Surgical correction of unilateral and bilateral congenital macrostomia: a case report and literature review

ABSTRACT

Introduction:

The incidence of craniofacial microsomia is 1 in 5600 live births. This is the second most common craniofacial anomaly after cleft lip and palate. Tessier cleft 7 is associated with 17% to 62% of cases of hemifacial microsomia. It begins on the labial commissure and may extend to the pre-auricular capillary line. Deformities of the external ear range from excessive pre-auricular skin to complete absence of the ear. Commissuroplasty is indicated in patients with macrostomia or true lateral facial cleft. The objective is to present two cases of macrostomia and perform a review of related literature.

Methods:

In this study, we describe two cases of macrostomia treated with mucous flaps and zetaplasty.

Results:

We obtained optimal repositioning of labial commissures in two patients, with excellent aesthetic results.

Conclusion:

The technique used is easily reproducible, and aesthetically and functionally corrects macrostomia.
