PURPOSE
Different interpositional materials have been used to prevent recurrence after gap arthroplasty in temporomandibular joint ankylosis. In this study, the versatility of the temporalis fascia as an interpositional arthroplasty was evaluated.
MATERIALS AND METHODS
Eight cases of unilateral temporomandibular joint ankylosis were evaluated, with a follow-up of 11 months to 6 years.
RESULTS
Patients had a preoperative maximal interincisal opening of 1 to 9 mm (mean, 2.75 mm). During the last follow-up observation after surgery, patients had a maximum interincisal opening of 32 to 40 mm (mean, 36.5 mm). Deviation to the affected side was observed in all cases. Paresthesia or anesthesia of the temporal branch of facial nerve was absent in all cases. Periodic panoramic radiographs showed that the intra-articular space was well maintained because of interposed tissue, without signs of relapse. There were no signs of reankylosis in any patient.
CONCLUSION
The findings of this study show that the temporalis fascia is a good alternative for interpositional arthroplasty.
目的
在颞下颌关节强直的间隙关节成形术中，已使用不同的植入材料来防止复发。在本研究中，评估了颞肌筋膜作为植入性关节成形术材料的适用性。
材料与方法
评估了8例单侧颞下颌关节强直患者，随访时间为11个月至6年。
结果
患者术前最大切牙间开口度为1至9毫米（平均2.75毫米）。在术后最后一次随访观察时，患者最大切牙间开口度为32至40毫米（平均36.5毫米）。所有病例均观察到向患侧偏斜。所有病例均未出现面神经颞支感觉异常或麻木。定期全景X线片显示，由于植入组织，关节内间隙保持良好，无复发迹象。所有患者均无再强直迹象。
结论
本研究结果表明，颞肌筋膜是植入性关节成形术的良好替代材料。
