The role of a temporalis fascia and muscle flap in temporomandibular joint surgery

Temporalis fascia, with a varying thickness of temporalis muscle, may be harvested as an axial flap based on the middle and deep temporal arteries and veins. The dependable blood supply, the proximity to the temporomandibular joint, and the ability to alter the arc of rotation by basing the flap inferiorly or posteriorly make this a versatile flap for lining the temporomandibular joint. In this report, the anatomy is reviewed, the harvesting technique is described, and multiple uses of the temporalis muscle-fascia flap in temporomandibular joint surgery are described.
