摘　　要：目的：对阻塞性睡眠呼吸暂停综合征（ＯＳＡＳ）患者牙颌颅面硬组织的形态特点进行系统评价，为选择合理的治疗方案提供理论依据。方法：借助Ｘ线头影测量对４４例ＯＳＡＳ患者的颅面结构进行测量，并与１００例无鼾症正常牙合人相应结构进行分析比较。结果：ＯＳＡＳ患者牙颌颅面结构特点为（１）颅底短，前颅底呈轻度逆时针旋转；（２）上颌后缩，长度正常；（３）下颌短，下颌与颏部明显后缩；（４）下颌后缩率为７０．５％；（５）前后面高比、下颌平面角较大；（６）上切牙突矩与倾斜较小，下切牙突矩及倾斜度较大，前牙覆牙合覆盖较大。结论：ＯＳＡＳ患者颅面形态倾向于安氏Ⅱ类高角病例。Objective:A　systematic cephalometric evaluation on a group of patients with obstructive sleep apnea syndrome(OSAS) was carried out, to provide morphological evidences for reasonable treatment of OSAS. Methods:The craniofacial skeletal morphology of 44 adult patients with OSAS was measured by cephalometry and compared with that of a control group consisting of 100 healthy persons with normal occlusion. Results:The significant aberrations in the OSAS group were(1)shorter dimension of anterior cranial base with slight counterclockwise rotation;(2)maxillary retrognathia with normal length;(3)shorter mandibular length with mandibular and chin retrognathia;(4)70.5 percent of the OSAS group with mandibular retrognathia;(5)increased ratio of anterior to posterior facial height and higher mandibular plane angle;(6)decreased protrusion and inclination of upper incisors,increased protrusion and inclination of lower incisors, and increased overjet and overbite. Conclusion: Craniofacial morphology of OSAS patients shows a tendency to that of Angle class Ⅱ high Angle cases.
