The Preservation Technique for Incomplete Unilateral Cleft Lip Reconstruction

Abstract

Summary:. The incomplete unilateral cleft lip shares many of the same phenotypic characteristics as a complete unilateral cleft lip, but key differences include an intact nasal sill, a relative excess of skin in the lateral lip element, and favorable skeletal support. Surgical techniques for incomplete unilateral cleft lips should be tailored to the specific anatomical characteristics, be simple and reliable to perform, and minimize the risk of secondary deformity. Here we describe the “preservation technique” for incomplete unilateral cleft lip reconstruction. The modified design from the anatomical subunit approximation technique uses a nasal sill flap and obviates the need for nasal sill and lateral lip excision. Tissues of the lip are opened out and reorientated to maximize the anatomical advantage.
