title: Orbicularis oris muscle: a double-breasted suture for its repair in the unilateral cleft lip.
abstract: The release of abnormal insertions of orbicularis oris muscle from the columella and ala base, and from their inferior attachments along the labial margin, provides muscle flaps for a double-breasted suture in cleft lip repair. Using the muscle flaps for double-breasted sutures realigns the orbicularis oris muscle fibers to achieve an anatomical and functional repair that is characterized by a symmetrical lip length, nostrils, philtral column, and philtral dimple. Double-breasted sutures also increase muscle thickness surrounding the lip and consequently provides better symmetry for the nostril floor.
