Oropharyngeal soft tissue profiles were studied by cephalometric analysis in 25 patients with obstructive sleep apnea syndrome (OSAS) and 10 controls. The length of the soft palate was significantly longer in patients (mean 48 mm) than in controls (mean 35 mm), as was the distance of close contact between the tongue and the soft palate. The thickness of the soft palate measured in the midsagittal plane was larger (mean 14 mm) than in the control group (mean 11 mm). The hyoid bone was more inferiorly positioned in patients than in controls, apparently giving the tongue a more upright position with more of the tongue tissue at the hypopharyngeal level than found in normals. In patients, the nasopharyngeal airway space, as well as the oropharyngeal airway space, had significantly reduced anteroposterior dimensions. Based on these data a new and modified surgical technique for treatment of OSAS patients has been developed. The surgical procedure is described, and some preliminary results concerning the effect of this operation in 16 patients are reported.
通过头影测量分析对25例阻塞性睡眠呼吸暂停综合征（OSAS）患者和10例对照者的口咽软组织轮廓进行了研究。患者软腭长度（平均48毫米）显著长于对照组（平均35毫米），舌与软腭紧密接触的距离也是如此。在正中矢状面测量的软腭厚度大于对照组（平均14毫米，对照组平均11毫米）。患者的舌骨位置比对照组更低，这显然使舌处于更直立的位置，与正常人相比，下咽水平的舌组织更多。在患者中，鼻咽气道空间以及口咽气道空间的前后径显著减小。基于这些数据，已开发出一种新的改良手术技术来治疗OSAS患者。描述了手术过程，并报告了该手术对16例患者疗效的一些初步结果。
