【Abstract】 Objective The clinical effect of the autogenous auricular cartilage graft that replaces or reconstructs the articular disc of the temporomandibular joint(TMJ) was evaluated.Methods The 13 discs of the 13 joints with 4 joints of internal derangement, 4 osteoarthrosis, 2 synovial chondromatosis, and 3 ankylosis were replaced or reconstructed with autogenous auricular cartilage grafts. Of them, shaving was performed in the 5 joints, temporalis fascia flaps were used to repair the lateral capsule in 2, and, auricular cartilage graft with tempralis fascia flap were used to get enough thickness in 1.Results At an average follow up of 6.5 months, clinical symptoms were improved in all patients. Maximal active opening was increased from 2.3cm to 3.3cm in ID, from 0.8cm to 2.7cm in ankylosis, and from 3.5cm to 3.9cm in synovial chondromatosis. Pain was releaved from 5-6 to 0-2(VAS) in OA, and from 7-8 to 0-1 in synovial chondromatosis. All grafts survived. There were no or slight deformities in the donors. Conclusions The autogenous auricular cartilage graft resembles the articular disc in the form and the thickness, and is a good material for replacing or reconstructing the articular disc of the temporomandibular joint.更多还原
