Anatomic Subunit Cleft Lip Repair: New Repair Concept Based on Nostril Sill and Philtrum-White Roll Junction.

A novel method for unilateral cleft lip repair based on lip anatomic subunits was presented in 2005 by David M. Fisher. It has about 25 landmarks with 2 arbitrary markings for the nostril. It is an important subunit when it comes to nose reconstruction. This article sheds light on the variance in nostril sill disposition among cleft lip patients. A novel marking technique based on differences in sills is presented. Furthermore, the unique anatomical structure of the philtrum-white roll junction is highlighted with a suggested modification to the subunit approximation leading to its reconstitution.
