Abstract

Abstract: PURPOSE: To evaluate the clinical efficacy of double wire anchorage in the treatment of temporomandibular joint disc anterior displacement. METHODS: Thirty patients with anterior disc displacement without reduction(ADDWoR) diagnosed in First Affiliated Hospital of Xinjiang Medical University from June 2021 to February 2022 were included to fix the discs with double wire anchors. The maximal open mouth, visual analogue scale (VAS) scores of the patients before and at different time periods were analyzed, the patients' self-satisfaction was recorded, and the length of MRI discs and condylar height before and after operation were measured. SPSS 25.0 software was used to analyze the data and evaluate the surgical results. RESULTS: The mean age was 24.43±8.87 years old, the mean mouth opening before operation was (29.17±5.38) mm (19-42 mm), the mean maximum mouth opening after operation was (39.17±2.57) mm (35-45 mm), and 93.3% of the patients after operation had the maximum mouth opening >35 mm; the mean VAS before operation was 58.33±21.19 (10-90), the mean VAS 6 months after operation was 11.67±6.99(0-20), the mouth opening and the value of VAS 6 months after operation had significant difference compared with prior to operation(P<0.05). The disc length was (9.77±0.63), (11.96±0.68) and (12.72±0.55) mm preoperatively, immediately postoperatively and 6 months after surgery. The condyle height increased by (1.08±0.61) mm 6 months after surgery compared with immediately postoperatively (P<0.05). CONCLUSIONS: Double wire anchorage in the reduction and anchorage of TMJ disc can improve the mouth opening, relieve pain, increase the length of TMJ disc and increase the height of condyle.
