- Abstract
PURPOSE: To introduce arthroscopic treatment of adhesion and evaluate the effect of arthroscopic surgery on IA of TMJ upper compartment. METHODS: 142 patients (159 joints) with intraarticular adhesion confirmed by arthroscope were treated with lysis of adhesions, intraarticular clean-up operation or capsules radiofrequency catheter ablation. 110 patients (123 joints) accompanied with disc displacement underwent disc repositioning and suturing. The follow-up index included jaw movement, VAS pain value and patients' self-evaluation. The therapeutic effect was divided into excellent, good and poor, and excellent and good patients were defined effective. Jaw movement and VAS pain value before and after operation were evaluated by paired t test using SPSS11.0 software package. RESULTS: The average follow-up period was 10.3 months (2 to 27 months). 33.80% (48/142) of all joints was excellent; 56.34% (80/142) of all joints was good, and only 9.86%(14/142) was poor. The total effective rate was 90.14% (182/142). 93.66% (133/142) of all patients felt more comfortable than that of before operation. The interincisal opening increased from preoperative (23.14±5.93)mm (range from 10 to 40mm) to postoperative (37.48±3.51)mm (range from 30 to 40mm) (P<0.01), and the pain scores reduced from 28.94±23.54(0∼80) to 4.44±10.10(0∼40) (P<0.05). CONCLUSIONS: The effect of arthroscopic surgery on TMJ IA is affirmative. Surgery can increase the patients' mouth opening, improve jaw function and reduced pain in the jaw movement.
