Synovial chondromatosis (SC) is a rare pathological condition that is characterized by the formation of cartilaginous nodules inside a joint cavity. It mainly affects the knee joints, hip, shoulder, and elbow, so the TMJ is rarely the target of such condition. Its etiology is still unknown and is usually diagnosed through magnetic resonance imaging (MRI), computed tomography (CT), histopathological exams, and, in some cases, arthroscopy, once the clinical inspection normally is not enough to conclude the diagnose. This study reports a case of a 35-year-old man that came to the Oral and Maxillofacial Surgery service complaining about limited mouth opening, occlusal dystopia, and increase of volume on the right pre-auricular region associated to pain. The SC diagnosis was suggested after realizing a CT and MRI. An Al-Kayat approach was performed to fully visualize the TMJ, removal of all the cartilaginous fragments, hemostasis and suture by layers. The diagnosis was confirmed through the histopathological exam. The patient evolved asymptomatic. |
