Abstract

Objectives: To describe the clinical and radiographic characteristics of patients with temporomandibular joint ankylosis treated by gap arthroplasty and autologous dermis-fat graft at Viet Duc University Hospital and the treatment outcomes of this patient group. Methods: Patients diagnosed with unilateral or bilateral temporomandibular joint ankylosis (intra-articular) based on clinical examination and imaging diagnosis were operated on by gap arthroplasty and autologous dermis-fat graft at Viet Duc University Hospital from March 2008 to March 2023 The study was designed as a descriptive prospective cross-sectional approach. Results: Male proportion is 75%, the majority of patients are between 19 and 39 years old (7/12 cases), the main cause is trauma (58.3%). Unilateral joint ankylosis occurred in 7 cases, the remaining 5 cases had bilateral joint ankylosis. The majority of grade is 3-4 according to Dongmei He (75%). Over 12 months after surgery, the average maximum interincisal opening was 25.3mm (this parameter before surgery was 8.6mm), there were two cases of recurrent ankylosis, and two cases of open bite. Successful treatment results 83.3%. Conclusions: Temporomandibular joint ankylosis is more common in men and after trauma. Treatment with gap arthroplasty and autologous dermis-fat graft can archive good results, it is simple, and easy to perform
