Platysmal Flaps for Cheek and Intraoral Reconstruction

Platysmal Flaps for Cheek and Intraoral Reconstruction




A turnover platysma muscle flap based superiorly and including an island of skin in its distal third is admirably suited for resurfacing the intraoral mucosa following excision of buccal mucosal tumors and cicatricial release of caustic burn scars as well as for resurfacing the oral surface of the lower lip and creating a deeper sulcus. It has the added attraction of providing sensitive skin to the buccal mucosa as well as to the lower lip (1).


The platysma is a well-defined, thin muscular sheet in males, but it can be hypoplastic, especially in females. It consists of paired muscles that are obliquely oriented and flat and that phylogenetically represent the remnants of the panniculus carnosus (2).

The platysma extends from above the mandible to below the clavicle, and its cephalad and caudad edges insert into the skin. The blood supply to the muscle comes most often from the submental branch of the facial artery superiorly, and a smaller vessel is noted that is a branch of the superficial cervical artery inferiorly. The skin overlying the platysma derives its sensory supply from the cutaneous branches of the cervical plexus. Its medial and lateral borders are easily identified from the strap muscles and the trapezius muscle, respectively.
