Temporomandibular joint disorders are common diseases characterized by joint clicking, limited mouth opening and pain, which have a huge impact on the patients' daily life. Conservative methods include medicine, physiotherapy and occlusal application. With the advancement of medical technology, the arthroscopy is becoming popular for its minimally invasion and high efficiency. This review focuses on the common arthroscopic methods, and provides an outlook of the arthroscopic surgery.

OBJECTIVE: To observe the clinical outcomes of a combined unilateral intraoral and extraoral reduction approach in the treatment of anterior temporomandibular joint (TMJ) dislocation. METHODS: Postural muscular chains were utilized in the biomechanical analysis of stomatognathic systems for improving TMJ repositioning approaches. A total of 87 patients with anterior TMJ dislocation were included in the present study. A combined unilateral intraoral and extraoral reduction approach was applied, and the clinical effects were evaluated. RESULTS: Biomechanical analysis reveal that reflexive contrac-tion of the maxillary muscle group was blocked sufficiently during the combined unilateral intraoral and extraoral reduction process. All dislocated TMJs were set successfully and efficiently with few complications. CONCLUSIONS Combined unilateral intraoral and extraoral reduction approach is an effective, convenient, and minimally invasive way to treat anterior TMJ dislo-cations.

OBJECTIVES: To evaluate the value of arthroscopy in the diagnosis and treatment of synovial chondromatosis of the temporomandibular joint (TMJSC). METHODS: The cases of 16 patients preliminarily diagnosed with TMJSC by magnetic resonance imaging (MRI) from July 2011 to December 2018 were analyzed retrospectively. If the diagnosis was confirmed by arthroscopy, the opening operation was performed. The preoperative MRI, arthroscopy and opening operation, postoperative pathology and postoperative MRI of confirmed cases were analyzed, and clinical follow-up was performed to evaluate the curative effect of open surgery. The degree of mouth opening and visual analogue scale (VAS) scores for pain pre-operation and during follow-up of the confirmed cases were analyzed by RESULTS: Fourteen cases of TMJSC were diagnosed by arthroscopy, consistent with the postoperative pathological diagnosis. Postoperative MRI examination showed that articular cavity lesions basically disappeared. Ten patients with synovial chondromatosis were followed-up (follow-up rate, 71.4%) from 6 months to 7 years and 8 months (average follow-up time, 17.6 months); no recurrence was found, and clinical symptoms improved by varying degrees. Before operation and at follow-up, CONCLUSIONS Arthroscopy is essential in the diagnosis and treatment of TMJ synovial chondromatosis.

OBJECTIVES: The aim of this study was to evaluate the implication of third molars in postoperative complications of mandibular angle fracture with open reduction and internal fixation (ORIF). MATERIALS AND METHODS: Data were collected on patients who presented with mandibular angle fracture at our Department of Oral and Maxillofacial Surgery between January 2011 and December 2015. Of the 63 total patients who underwent ORIF and perioperative intermaxillary fixation (IMF) with an arch bar, 49 patients were identified as having third molars in the fracture line and were followed up with until plate removal. The complications of postoperative infection, postoperative nerve injury, bone healing, and changes in occlusion and temporomandibular joint were evaluated and analyzed using statistical methods. RESULTS: In total, 49 patients had third molars in the fracture line and underwent ORIF surgery and perioperative IMF with an arch bar. The third molar in the fracture line was retained during ORIF in 39 patients. Several patients complained of nerve injury, temporomandibular disorder (TMD), change of occlusion, and postoperative infection around the retained third molar. The third molars were removed during ORIF surgery in 10 patients. Some of these patients complained of nerve injury, but no other complications, such as TMD, change in occlusion, or postoperative infection, were observed. There was no delayed union or nonunion in either of the groups. No statistically significant difference was found between the non-extraction group and the retained teeth group regarding complications after ORIF. CONCLUSION: If the third molar is partially impacted or completely nonfunctional, likely to be involved in pathologic conditions later in life, or possible to remove with the plate simultaneously, extraction of the third molar in the fracture line should be considered during ORIF surgery of the mandible angle fracture.

We conducted a retrospective study and reviewed the temporomandibular joint (TMJ)-related papers published in a leading international journal, Journal of Oral and Maxillofacial Surgery, between January 2014 and December 2015. The study was conducted to ascertain and compare the trends of articles being published in the years 2014 and 2015. A total of 28 articles were reviewed, of which most of the full-length articles were on clinical management and outcomes and the role of radiology. The bulk of the studies were prospective, and less interest was shown in experimental research. A thorough review and analysis thus gives the impression that there is a great need for well-designed clinical studies on TMJ.

temporomandibular joint (TMJ) pain and dysfunction occurred in some patients after orthognathic surgery, and one possible explanation is related to these changes in condylar position. The improvement in the occlusion from orthognathic surgery may play a role in improvement of symptoms. The purpose of present study was to investigate the incidence of preoperative and postoperative symptoms of TMJ disorders in patients with orthognathic surgery. The study group consisted of 72 males and 68 females in mandibular prognathism. The total number of 140 patients were carried out SSRO (82 cases), IVRO (14 cases), Le Fort I and SSRO (32 cases), Le Fort I and IVRO (5 cases), and ASO (7 cases). In the patient group with no TMJ dysfunction preoperatively (119 cases, 85%), 14.3% (17 cases) developed a problem postoperatively. In the patient group with TMJ symptom preoperatively (21 cases, 15%), 66.7% (14 cases) solved a symtom postoperatively.]]>
