To determine accurately the morphological characteristics specific to patients with sleep apneas syndrome (SAS), a group of 43 adult males with SAS was compared in a cephalometric evaluation with a homologous control group. In SAS patients, the soft palate was elongated; the sagittal dimensions of upper face and anterior cranial base were reduced and correlated with reduced bony pharynx opening; and the increased lower face height was associated with a retruded position of the chin and tongue, thus contributing to lower pharynx crowding. With the four variables entering the discriminant function analysis, 93 percent of the whole population was correctly classified. If anatomical rehabilitation of the pharynx is to be envisaged, the leading factors to consider should be: soft palate length, maxillary position, chin and tongue position, in that order.
为准确确定睡眠呼吸暂停综合征（SAS）患者特有的形态学特征，对一组43名成年男性SAS患者进行了头影测量评估，并与同源对照组进行比较。在SAS患者中，软腭伸长；上颌面部和前颅底的矢状径减小，且与骨性咽口减小相关；下颌面部高度增加与下巴和舌头后缩位置有关，从而导致下咽拥挤。通过将这四个变量纳入判别函数分析，93%的总体人群被正确分类。如果考虑对咽部进行解剖学重建，应按以下顺序考虑主要因素：软腭长度、上颌位置、下巴和舌头位置。
