Abstract: Calcium pyrophosphate dihydrate crystal deposition disease (CPPD) refers to calcium pyrophosphate crystals deposited in articular fibrocartilage, hyaline cartilage and its surrounding synovium, ligaments, tendons and joint capsules. CPPD is idiopathic in most patients, however, it has been associated with aging, osteoarthritis, gout, hyperparathyroidism and metabolic disorders like hemochromatosis and hypomagnesemia. In this paper, a female patient with CPPD of temporomandibular joint(TMJ) was reported,in which the lesion invaded cranial base, the condyle and disc of TMJ. Surgical procedure was performed to remove the lesion and reconstruct cranial base and TMJ.

Key words: Calcium pyrophosphate dihydrate crystal deposition disease, Temporomandibular joint, Condyle reconstruction
