The Tennison Lip repair revisited.

Tennison presented his method for the repair of the single cleft. He was the first to recognize and to preserve the cupid's bow by lowering the peak in the margin of the cleft. He incised the medial side of the cleft and filled the space with a triangular flap from the lateral side. We have modified the Tennison repair based on the vertical height of the normal side, as did Randall and Hagerty. We make the lip 1 mm shorter in the vertical height than the normal side because some of our repairs were too long. Other modifications include a 1-mm offset at the vermilion, and in certain lips that are too long in the newborn, a triangle is excised beneath the alar base to shorten the vertical height. The details for planning the incisions and accomplishing the surgery are given. Certain patients required a V-to-Y procedure to augment a vermilion deficiency, but none of these patients required a secondary procedure. This emphasizes the need for careful planning to get it right at the primary repair. The operation is indicated for the incomplete cleft to the very wide cleft, and in no patient was a lip adhesion required. We no longer operate on the nose at the primary repair.
