Reconstruction of Large Defects of the Lips and Commissure Using a Composite Radial Forearm Palmaris Longus Free Flap Associated With a Lengthening Temporalis Myoplasty

We performed a single-stage operation to reconstruct a large defect of the lips and commissure using a composite radial forearm-palmaris longus free flap. To obtain cranial traction and a voluntary smile, independently from any jaw movement, traction was achieved by using a lengthening temporalis myoplasty. The tendon attached to the coronoid process was fixed to the palmaris longus tendon, recreating a new commissure and a "neo-modiolus." Physical therapy was started on the 21st postoperative day to facilitate progress from a "mandibular smile," to ideally a spontaneous and symmetric smile after 3 months of therapy. This procedure was able to obtain good oral continence and a good commissural movement during smile which has not previously been mentioned in the published literature.
