The temporalis muscle flap in temporo-mandibular joint surgery

In the treatment of the severely damaged TMJ structural components (ankylosis, arthrosis, tumour, perforation or degeneration of the disc), it is advisable to insert a biological interposition between bony articular surfaces. The temporal muscle, due to its anatomical, topographical, and functional properties, can be successfully employed for this purpose. Based on the experience of Tessier, Delaire and Rowe, a temporalis muscle flap, inferiorly based, is rotated downwards and medially to the zygomatic arch, interposed and then fixed to condyle and capsule. Using this surgical technique, 12 patients and 13 temporo-mandibular joints were treated with good functional results and without any complication.
