Temporomandibular joint(TMJ) ankylosis is characterized by the formation of bony or fibrous mass, which replaces the normal articulation. Ankylotic block formation causes reduction of mandibular mobility, particularly hindering mouth opening, due to a mechanical block of the condylar head in its roto-transfatory motion. Surgery in TMJ ankylosis treatment entails complete ankylotic block removal and subsequent arthroplasty, possibly with autologous tissue between articular surfaces or heterologous material to restore the anatomic structure and normal function. Temporalis myofascial flap holds great promise for the reconstruction of various maxillofacial defects. In more recent years, a pedicled temporalis myofascial flap has been advocated in TMJ ankylosis surgery. Advantages of the temporalis myofascial flap in TMJ reconstruction include close proximity to the TMJ, adequate blood supply from the internal maxillary artery, and its attachment to the coronoid process, which provides movement of the flap during function, simulating physiologic action of the disc. This study evaluated 8 patients(11 TMJs) affected by TMJ ankylosis. All patients underwent surgical treatment of the removal of the ankylotic block and subsequent interpositional arthroplasty with temporalis myofascial flap. Bilateral TMJ ankylosis was observed in 3 patients(6 TMJs), right-sides in 3 patients, left-sided in 2 patients. Epipathogenesis was traumatic in 6 patients(8 TMJs), ankylosing spondylitis in 2 patients(3 TMJs). In 3 patients coronoidotomy was underwent. Average follow-up was 16.8 months after surgery, with a range of 7 to 28 months. No patients underwent additional TMJ procedures after the temporalis myofascial flap. All patients showed a distinctive improvement both in articular functionality and symptoms. We found that temporalis myofascial flap is very valuable in reconstruction of TMJ ankylosis.

Management of temporomandibular joint (TMJ) ankylosis is challenging for the oral and maxillofacial surgeon because it involves the mouth opening, dentofacial deformity, diet problem, and quality of life. Although surgical techniques to treat TMJ ankylosis have improved, reankylosis is a persistent problem. The temporalis myofascial flap provides good material for interpositional arthroplasty, because of its good vascular supply, anatomic proximity, and adequate thickness. This case report examines the efficacy of submandibular anchorage to prevent reankylosis by inhibiting flap dislocation.

악관절 강직증의 치료는 기술적 어려움과 높은 재발율로 인해 난관에 부딪히고 있다. 악관절 강직증은 골절제와 이종, 동종, 자가 물질을 이용한 악관절 재건술로 치료를 해왔다. 측두근-근막피판은 그것의 해부학적, 지리적, 기능적 성질로 인해 우수한 간치 이식물질로 여겨지고 있다. 본 연구는 전이개 절개, 근돌기 절제술과 병행한 아홉개의 악관절(다섯명의 환자)강직의 치료에서 측두근-근막피판의 효율성에 대해 알아 보았다. 그 결과 측두근-근막 피판은 이상적인 간치 이식물질의 기준을 만족하는 자가물질로 여겨지며 disc의 생리적 기능을 수행하는것으로 사료된다. 그러나, 이러한 우수한 기능적 결과에도 불구하고 술후 약간의 전치부 개교경향은 또다른 문제점으로 남아있다.

Background: The purpose of this study was to investigate the functional effects of temporalis myofascial flap after condylectomy, with or without disc removal, in elderly patients with anterior disc displacement (ADD) without reduction and an erosive condylar surface of the temporomandibular joint (TMJ). Methods: A total of 15 joints from 11 elderly patients (71-78 years old) were included. The patients had pain, mandibular dysfunction symptoms, and unilateral or bilateral ADD as well as an erosive condylar surface of the TMJ. All patients underwent temporalis myofascial flap reconstruction after condylectomy, with or without disc removal. If the maximal mouth opening (MMO) remained <35 mm after condylectomy, coronoidotomy was also performed. Self-assessed pain and mandibular function, including MMO and protrusive and lateral movements, were evaluated. Results: No patient experienced serious complications. Most measurements improved significantly after surgery compared to preoperatively. Most patients achieved nearly-normal mouth opening at 4 weeks after surgery. Although most patients felt discomfort during active postoperative physiotherapy, no patient reported serious pain during the follow-up period. Conclusion: Although nonsurgical therapy is often the first treatment choice for ADD without reduction of the TMJ, surgical intervention involving condylectomy and temporalis myofascial flap reconstruction may be a reasonable first option for elderly patients with an erosive condylar surface of the TMJ.
