目的：评估用正颌外科技术矫治９例颞颌关节强直所致睡眠呼吸暂停综合征的效果。方法：采用患侧关节成形，下颌升支、体部的“Ｌ”型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：９例颞颌关节强直后睡眠呼吸暂停综合征患者术后张口度达２．５～３．５ｃｍ，连续血氧饱和度最低值由术前的５８％提高至术后的９５％以上，唾眠呼吸暂停综合征得以治愈。结论：颞颌关节强直后睡眠呼吸暂停综合征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。
Objective: To evaluate the effect of orthognathic surgery on 9 cases of sleep apnea syndrome caused by temporomandibular joint ankylosis. Methods: The ipsilateral mandibular ascending anastomosis was fixed and the anterior mandibular anterior whole was advanced by means of ipsilateral arthroplasty, ascending mandibular branch, “L” type half osteotomy and contralateral sagittal osteotomy. Results: Nine patients with temporomandibular joint ankylosis sleep apnea syndrome postoperative mouth opening 2.5 ~ 3.5cm, the lowest continuous oxygen saturation increased from 58% preoperative to postoperative 95% Sphincter apnea syndrome can be cured. CONCLUSIONS: Orthognathic surgery in patients with TMJ obstetric appendectomy can alleviate or correct hypoxemia in patients with mandibular retraction defects and upper airway stenosis, while at the same time shaping the joint.
