Treatment of calcium pyrophosphate deposition in the temporomandibular joint with resection and simultaneous reconstruction using a custom joint prosthesis.

PURPOSE: The authors present a rare case of calcium pyrophosphate deposition disease (CPPD) in the temporomandibular joint (TMJ), successfully treated with complete resection and immediate reconstruction using a custom-made prosthesis. This one-stage approach has prevented the patient from requiring two surgeries and has proven effective in the management of the condition. METHODS: Our patient, a 56-year-old male, presented with left TMJ pain and trismus. Investigations showed a destructive left TMJ mass, confirmed by biopsy to be tophaceous pseudogout. The treatment involved excising all the affected tissues followed by condylectomy, coronoidectomy, and a total TMJ replacement. The patient recovered well from surgery with good mouth opening. RESULTS: CPPD disease is a metabolic arthropathy of poorly understood aetiology. Management options vary from conservative non-surgical to surgical treatment depending on the severity. CONCLUSION: This case demonstrates the feasibility of a one-stage procedure with reconstruction using a custom-made prosthesis and virtual planning.
