Abstract:
BACKGROUND:Due to complex etiology, manifestations, symptoms, development and outcomes, there is no article about the detailed introduction of condylar resorption in China. OBJECTIVE:To analyze the etiology, pathogenesis, clinical manifestations, diagnosis and treatment of condylar resorption, thereby providing a theoretical basis for clinical treatment of condylar resorption. METHODS:An online computer-based retrieval of PubMed database and CNKI database between January 1990 and January 2014 was performed by the first author. The keywords were “temporomandibular joint, condylar resorption, pathogenesis, diagnosis, treatment” in English and Chinese, respectively. Finaly 38 literatures on the etiology, clinical presentation, diagnosis and treatment of condylar resorption were included. RESULTS AND CONCLUSION: Condylar resorption was subdivided into secondary condylar resorption and primary condylar resorption. Secondary condylar resorption has clear risk factors, including condylar fractures, orthognathic surgery, connective tissue or autoimmune diseases and rheumatoid arthritis. Primary condylar resorption may be associated with lowered serum estradiol concentration. Condylar resorption can be diagnosed by imaging studies combined with clinical manifestations and disease history. Condylar resorption treatment measures mainly include medications, splint treatment, occlusal reconstruction, orthognathic surgery, rib-cartilage transplantation and total joint replacement surgery, in conjunction with orthodontic treatment. Currently, its complex etiology and pathogenesis has not been fuly elucidated, and we need to conduct further studies.
