摘要
目的 :用L值评估正颌外科技术矫治 12例颞颌关节强直所致SAS的效果。方法 :手术采用患侧关节成形 ,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。上颌骨LefortⅠ型截骨 ,向健侧旋转 ,纠正偏移 ,并行颏成形术。比较分析术前、术后的L值。结果 :12例颞颌关节强直所致OSAS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 5 8%提高至术后的 95 %以上 ,术后L值较术前L值有较大的提高 ,术后AKI指数较术前AHI指数大幅下降 ,OSAS得以治愈。结论 :颞颌关节强直所致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。
Objective:By means of L value to evaluate the curative effects of orthognathics surgery technique in the treatment of 12 patients with OSAS due to ankylosis of temporomandibular joint.Methods:Arthroplasty at the affected side, type 'L' semi-layer osteotomy at the posterior border of the ramus of mandible and the body of the mandible,as well as sagittal osteostomy at the normal side are performed.The ramus of mandible at the affected side is heightened and fixed.The anterior part of mandible is pulled forward.Maxillary bone undergoes Lefort Ⅰ osteotomyand and is rotated toward the normal side.The deviation is corrected and gnathoplasty is performed.Pre-operative and post-operative L values are compared and analyzed.Results:Post-operative maximal mouth opening of the 12 patients with OSAS due to ankylosis of temporomandibular joint approaches 2.5～3.5cm.Continuous blood oxygen saturation increase from 58% to over 95%.Post-operative L value is higher than pre-operative L value.Thus OSAS is cured.ConclusionsOrthognathic surgery can solve the problem of mandibular retrognathia, remove the blockage of the upper airway and relieve or correct the hypoxemia of the patients with OSAS due to ankylosis of temporomandibular joint.
