The objective of this study was to compare the head posture of patients with obstructive sleep apnea (OSA) having different levels of severity with that of control subjects.
One hundred subjects participated in this study. Seventy-five subjects underwent overnight polysomnography in a sleep laboratory and were allocated into "mild," "moderate," or "severe" OSA groups, and 25 subjects with no complaints regarding OSA were allocated into 1 group and served as the controls. Cephalometric radiographs were obtained from all participants in natural head position. Craniocervical, craniovertical, and cervicovertical angles were measured in the groups. Data were analyzed using the least significant difference.
The results showed significant differences between the OSA groups and the control group, and among the test groups, in all craniocervical, craniovertical, and cervicovertical angles (P <0.05), except for 1 craniovertical measurement (P >0.05). There were no significant differences in this measurement among the test groups and in any measurement between the mild and moderate OSA groups (P >0.05).
Head posture showed significant differences in patients with OSA. In general, the more severe the OSA, the more extended the natural head position as indicated by increases in the craniocervical angles. The cervical posture parameters may indicate existing OSA.
本研究的目的是比较不同严重程度的阻塞性睡眠呼吸暂停（OSA）患者与对照组受试者的头部姿势。
100名受试者参与了本研究。75名受试者在睡眠实验室接受了整夜多导睡眠监测，并被分为“轻度”、“中度”或“重度”OSA组，25名无OSA相关主诉的受试者被分为1组作为对照组。在自然头位下为所有参与者拍摄头颅侧位X线片。测量各组的颅颈角、颅垂直角和颈垂直角。采用最小显著差法分析数据。
结果显示，除1项颅垂直测量值外（P>0.05），OSA组与对照组之间以及各测试组之间在所有颅颈角、颅垂直角和颈垂直角上均存在显著差异（P<0.05）。该测量值在各测试组之间以及轻度和中度OSA组之间的任何测量中均无显著差异（P>0.05）。
OSA患者的头部姿势存在显著差异。一般来说，OSA越严重，颅颈角增加表明自然头位越伸展。颈椎姿势参数可能提示存在OSA。
