Periarticular chondrocalcinosis of the left temporomandibular joint: A case report
Abstract
Chondrocalcinosis is a non-infectious, inflammatory arthropathy which is typically characterized by intra-articular deposition of calcium pyrophosphate dihydrate crystals. The occurrence of chondrocalcinosis in the temporomandibular joint is uncommon. This report describes the case of a 51-year-old female with periarticular chondrocalcinosis of the left temporomandibular joint. Disease progression and prolonged complaints of pain and limitation of mouth opening were indications for surgical treatment. The placement of an alloprosthesis of the left temporomandibular joint was performed simultaneously with a unilateral sagittal split ramus osteotomy of the right side of the mandible, to correct the class 2 malocclusion in this patient. In this case, an initial clinical diagnosis of synovial chondromatosis was made. Postoperative histopathological analysis changed the diagnosis to chondrocalcinosis. The deposition of calcium pyrophosphate dihydrate crystals was located in the outer joint capsule, which is an atypical localization of chondrocalcinosis of the temporomandibular joint.
