正颌外科技术治疗TMJ后OSAS(英文)

目的 评估正颌外科技术矫治14例颞颌关节强直所致OSAS的效果。方法 手术采用患侧关节成形,下颌升支、体部的“L”形半层截骨及健侧矢状截骨术,将患侧下颌升支加高固定,下颌前部整体前移。结果14例颞颌关节强直伴OSAS患者术后张口度达2.5～3.5cm,术后2年随访张口度仍维持在2.5～3.2cm之间。所有患者的AHI指数下降了20以上,12例患者的打鼾症状消失,持续血氧饱和度平均提高了18.45％（P<0.01）,达到了正常人的范围,持续血氧饱和度最低值由术前的58％提高至术后的95％以上,OSAS得以治愈。结论 颞颌关节强直伴OSAS患者通过正颌外科手术可以在关节成形的同时,解决患者下颌后缩的缺陷,解除上气道狭窄,从而缓解或纠正患者的低氧血症。

TREATMENT OF SLEEP APNEA SYNDROME DUE TO ANKYLOSIS OF TMJ USING ORTHOGNATHIC SURGERY TECHNIQUE

ve To evaluate orthognathic surgery in the treatment of sleep apnea syndrome (SAS) resulted from ankylosis of TMJ. Methods Firstly, the arthroplasty was carried out to relieve the TMJ ankylosis and to open mouth according to design. The mandibles of 14 patients with SAS were advanced by "L"-osteotomy of ramus at the affected side and a sagittal split ramus osteotomy at normal side combined with TMJ arthroplasty. Results After operation, maximal mouth opening of the 14 patients reached 2.5cm -3.5cm. The follow-up 2 years later showed the maximal mouth opening was kept between 2.5cm and 3.2cm. AHI of all the patients were less than 20 postoperatively. Snoring while asleep disappeared in 12 patients and their SaO2 increased by 18.45% in average (P <0.01), which fell into the normal range. No patients were waken up by suffocation. Continuous SaO2 increased from 58% to over 95 % in average. Conclusion The obstruction of the upper airway can be relieved through orthognathic surgery. Thus the hypoxemia of the patients was relieved or corrected. This technique is effective in the treatment of SAS due to TMJ ankylosis.
