The aim was to obtain normative data for cephalometric measurements of the upper airway in the North Indian population.
Observational study.
University department and teaching hospital out-patient clinic.
A total of 180 healthy patients were included out of which 90 were males (age range, 8-16 years), and 90 were females (age range, 8-16 years), with normal skeletal facial profile, no history of snoring, sleep apnea, upper airway disease, tonsillectomy or adenoidectomy, obesity, or pathology in the pharynx. Twenty cephalometric airway measurements, including size of the tongue, soft palate, nasopharynx, oropharynx, hypopharynx, and relative position of the hyoid bone and valleculae were obtained. Landmarks on cephalometric radiographs were digitized and measurements were made using a specially designed computer program. Error analysis of measurements was performed and comparison of measurements according to sex was made.
Significant sex dimorphism was seen for the majority of measurements, with the exception of minimal depth of the airway, oropharyngeal depth of the airway, and the soft palate angle with the hard palate.
A minimum sagittal dimension of the upper airway was evident despite differences in measurements between sexes. Findings from this study should be a useful reference for the assessment of sleep apnea in the North Indian population.
旨在获取北印度人群上气道头影测量的标准数据。
观察性研究。
大学科室及教学医院门诊。
共纳入180名健康患者，其中90名男性（年龄范围8 - 16岁），90名女性（年龄范围8 - 16岁），面部骨骼轮廓正常，无打鼾、睡眠呼吸暂停、上气道疾病、扁桃体切除术或腺样体切除术史，无肥胖或咽部病变。获取了20项头影测量气道指标，包括舌、软腭、鼻咽、口咽、下咽的大小，以及舌骨和会厌谷的相对位置。对头影X线片上的标志点进行数字化处理，并使用专门设计的计算机程序进行测量。进行了测量的误差分析，并按性别进行了测量比较。
除气道最小深度、口咽气道深度以及软腭与硬腭夹角外，大多数测量指标存在显著的性别差异。
尽管男女测量结果存在差异，但上气道矢状径最小值是明显的。本研究结果应为北印度人群睡眠呼吸暂停的评估提供有用的参考。
