Minor-form/microform cleft lip repair: the importance of identification and utilization of Cupid bow peak on the lateral lip.

Abstract

In minor-form or microform cleft lip, normal anatomical structures with slight displacement remain and should be used effectively to obtain symmetrical results. We treated 7 patients with minor-form or microform cleft lip between 2005 and 2009. In all patients, the peak of Cupid bow with a natural curve of the white roll was recognized on the lateral lip. We modified the incision line to maintain the natural curve and obtained a symmetrical and natural-looking Cupid bow. In this article, we emphasize the importance of preserving the remaining normal structure, particularly the curve of the white roll on the lateral lip, and suggest that the peak of the curve should be defined as Cupid bow peak of the cleft side. Details of our concept for the correction of minor-form or microform cleft lip are also introduced.
