A case is presented in which the upper lip of a 20-year-old woman was augmented by a graft of palmaris longus tendon-muscle. This technique offers several advantages over other lip enlargement techniques. The primary drawback, in my opinion, is the possibility that lip excursion (smiling, animation) might be restricted by tendon-muscle adherence to lip tissues, although this did not occur in this patient. Experience with larger numbers of patients is necessary before this technique can be endorsed for general use.
