OBJECTIVE: This study aimed to retrospectively analyze temporomandibular joint dislocation by surgical treatment 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%.
CONCLUSIONS: The surgical method of temporomandibular joint dislocation was selected according to the state of the patients. The postoperative 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.
