Open surgery and arthroscopy for the treatment of synovial chondromatosis (SC) of the temporomandibular joint (TMJ) have their advantages and disadvantages. The aim of this study was to report the application and results of the combined use of these two methods in the treatment of SC and the indications for use. A total of 36 patients with magnetic resonance imaging (MRI) confirmation of SC, treated from 2010 to 2015, were included. Patients with tumours in the upper articular cavity and with the extended margin of the medial groove still in-between the medial crest of the condyle and infratemporal space on coronal MRI were selected to undergo open surgery with the assistance of arthroscopy to clear the loose bodies and affected synovium. All 36 patients first went through open surgery. Subsequent arthroscopy examinations indicated the presence of loose bodies in the medial groove in 14 patients (in the anterior or posterior recess), which were removed using a cup-shaped clamp. Thirty-three of the patients were followed up for an average of 33.3 months; there was no recurrence in these patients. This technique has the benefits of the complete elimination of diseased tissues with a minimal osteotomy and a short surgical duration.
