这项前瞻性研究分析了 115 名有齿的白人男性的直立侧位头影测量 X 光片。 45 名受试者表现出已证实的阻塞性睡眠呼吸暂停 (OSA)，46 名是简单打鼾者，其余 24 名没有呼吸道疾病史且不打鼾的受试者作为对照。对射线照片进行追踪和数字化，并对三组的牙骨骼、软组织和口咽特征进行比较。还在打鼾和 OSA 受试者之间寻找差异。在硬组织测量中，只有颅底角和下颌体长度显示出显着的组间差异（分别为 P < 0.001 和 P < 0.05）。当检查气道和相关结构时，打鼾者和 OSA 受试者都表现出比对照组更窄的气道、减少的口咽面积、更短和更厚的软腭以及更大的舌头。两个睡眠呼吸障碍组的比较显示，所检查的任何骨骼或牙齿变量都没有差异。然而，在 OSA 受试者中，软腭更大更厚（P < 0.05），舌和口咽面积均增大（分别为 P < 0.01 和 P < 0.05），并且舌骨距离下颌平面更远（P < 0.05）。因此，虽然打鼾者的牙骨骼模式与 OSA 受试者相似，但软组织和舌骨方向存在一些差异很明显。然而，从控制到打鼾到 OSA 受试者，气道及其相关结构的大小并没有明显的分级。这表明，可能存在一种从头颅测量上可识别的易患睡眠呼吸障碍的倾向，但这只是该病症的一个方面。
This prospective study analysed the upright lateral cephalometric radiographs of 115 dentate, Caucasian males. Forty-five subjects exhibited proven obstructive sleep apnoea (OSA), 46 were simple snorers, and the remaining 24 subjects, who had no history of respiratory disease and did not snore, acted as controls. Radiographs were traced and digitized, and comparisons were made of the dento-skeletal, soft tissue, and oropharyngeal features of the three groups. Differences were also sought between the snoring and OSA subjects.Of the hard tissue measurements, only the cranial base angle and mandibular body length showed significant inter-group differences (P < 0.001 and P < 0.05, respectively). When the airway and associated structures were examined, both snorers a nd OSA subjects exhibited narrower airways, reduced oropharyngeal areas, shorter and thicker soft palates, and larger tongues than their control counterparts. Comparison of the two sleep disordered breathing groups showed no differences in any of the skeletal or dental variables examined. However in OSA subjects, the soft palate was larger and thicker (P < 0.05), both lingual and oropharyngeal areas were increased (P < 0.01 and P < 0.05, respectively) and the hyoid was further from the mandibular plane (P < 0.05).Thus, whilst the dento-skeletal patterns of snorers resembled those of subjects with OSA, some differences in soft tissue and hyoid orientation were apparent. There was not, however, a recognizable gradation in size of the airway and its associated structures from control through snoring to OSA subjects. This suggests that there may be a cephalometrically recognizable predisposition towards the development of sleep disordered breathing, but that this is only one facet of the condition.
