Abstract:

Objective This study aimed to retrospectively analyze temporomandibular joint dislocation by surgical treat-ment and evaluate the treatment effect. Methods From May 2012 to April 2016, a total of 17 cases of temporomandibular joint dislocation were surgically treated, including 8 cases of irreducible dislocation (ID) and 9 cases of recurrent dislocation (RD). Synovial injection of sclerosing agent by arthroscope was performed in 5 cases, 9 sides; augmentation of the articular eminence by titanium plate implantation was performed in 7 cases, 12 sides; iliac bone transplantation was performed in 1 case, 1 side; Medpore implantation was performed in 3 cases, 6 sides; and eminectomy and capsular tightening were performed in 1 case, 2 sides. Follow-up was conducted 1-5 years after the operation, and the success rate statistics was obtained. Results The cure rate of synovial injection of sclerosing agent by arthroscope was 77.8% (7/9), and the effective rate was 100%. The cure rate of titanium plate implantation was 75% (9/12), and the effective rate was 100%. The cure rates of augmentation of the articular eminence by Medpore implantation (6/6), iliac bone graft (1/1), and eminectomy (2/2) were 100%. Conclusion The surgical method of temporomandibular joint dislocation was selected according to the state of the patients. The postope-rative recurrent patients were advised to undergo augmentation of the articular eminence by Medpore implantation, which offered a reduced chance of recurrence and relatively less injury, as well as a simple operative method.
