Temporomandibular arthrosis allegedly results from the intricate involvement of several factors.<BR>However, the relationship between the development of mandibular deformity and temporomandibular arthrosis has been a topic of increasing attention. Briefly presented here is a case of mandibular deformity diagnosed among patients examined at our department for the chief complaints of temporomandibular arthrosis and malocclusion. The mandibular deformity was surgically treated, and the discs of the temopromandibular joint (TMJ) were fixed by arthroscopic suturing causing the temporomandibular arthrosis to disappear.<BR>The patient was a 25-year-old female examined by our department for the chief complaints of bilateral pain in the TMJ, clicking of the left TMJ, and malocclusion. Mandibular defromity and malocclusion were present, and double-contrast CT scan of the TMJ led us to suspect discus articularis dislocation.<BR>The therapy we instituted consisted of occlusal rectification by sagittal splitting of the mandible and arthroscopic suturing and fixation of the right disc. Eleven months postoperatively, facial symmetry has been restored, occlusion improved, and temporomandibular arthrosis alleviated.
