摘　　要：目的:评价牵引成骨术治疗儿童单侧颞下颌关节强直伴阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的治疗效果。方法:4例儿童单侧颞下颌关节强直伴发OSAHS患者,男女各2例,年龄5～13岁(中位年龄6.5岁)。均采用颞下颌关节成形术以恢复开口功能,下颌体牵引成骨术治疗OSAHS;其中3例行同期手术,1例行分期手术;单侧和双侧下颌体牵引各2例。固定期约3个月时行呼吸监护仪监测(PSG)复查和牵引器拆除术。结果:4例患儿OSAHS症状均消失,平均AHI由术前的42.7降到4.9,平均最低血氧饱和度由术前的74.3%上升到89.8%;平均开口度由6.5mm增加至25.5mm;面部畸形得到满意矫正。经过平均38.1个月(13～58个月)的随访,无1例复发。结论:下颌骨牵引成骨术联合颞下颌关节成形术能够有效地治疗儿童单侧颞下颌关节强直及其伴发的OSAHS、面部不对称畸形,并且可以同期手术。PURPOSE： To evaluate the efficiency of distraction osteogenensis for treatment of unilateral temporomandibular joint ankylosis and secondary OSAHS in children. METHODS： 4 children with temporomandibular joint ankylosis and secondary OSAHS were retrospectively reviewed for their treatment. There were 2 males and 2 females, ranging from 5 to 13 years in age with the median of 6.5 years. Based on the history of the disease, the clinical manifestations, CT scan and PSG findings, the diagnosis was confirmed to be unilateral temporomandibular joint ankylosis and secondary OSAHS. All the patients were treated by gap arthroplasty to restore mouth opening, combined with mandibular body distraction osteogenesis for treatment of OSAHS. One-stage operation was performed on 3 patients, and two-stage operation on 1 patient. Unilateral and bilateral mandibular distraction osteogenesis was undergone on 2 patients individually. At the end of consolidation period of 3 months, the PSG examination was performed again and the distractor was removed. RESULTS： OSAHS was cured, the average AHI was lowered from 42.7 to 4.9, the average lowest saturation of blood oxygen rose from 74.3% to 89.8%, the average incisor distance reached 25.5mm compared to 6.5mm before surgery and facial deformity was corrected satisfactorily. Following up 38.1 months （13-58 months）, no relapse appeared. CONCLUSION： Mandibular body distraction osteogenesis, combined with gap arthroplasty, could be the potential treatment modality of children with milateral temporomandibular joint ankylosis,secondary OSAHS and facial asymmctry：it is recommended that both procedures be performed at the same time.Suppored by Shanghai Leading Academic Discipline Project（Y0203）.
