The dimensions of the pharyngeal air space (PAS) are influenced by certain factors, including different facial morphological patterns and/or accumulation of fat on the pharyngeal walls, potentially affecting sleep quality and predisposing individuals to obstructive sleep apnea-hypopnea syndrome (OSAHS).
The PAS dimensions and the area of greatest pharyngeal constriction in individuals with an angle class I maxillomandibular relationship and a BMI > 25 kg/m², correlating these with cervical and abdominal measures and sleep quality data. Cone-beam computed tomography (CBCT) scans of 50 participants (25 of each sex, aged 18 years or older, Class I occlusion, BMI > 25 kg/m²) were analyzed via Dolphin Imaging 11.95 software to determine the PAS area and volume. Participants also had their waist and neck circumferences measured, in addition to sleep quality assessment through the application of the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS) and the Berlin Questionnaire (BQ).
Significant correlations were found between oropharyngeal dimensions, BMI, and abdominal circumference. Higher BMI was associated with decreased oropharyngeal volume. Total PAS, oropharynx, hypopharynx, and maximum pharyngeal constriction values were significantly linked to excessive daytime sleepiness. A reduced total PAS was also associated with increased OSAHS risk. No significant differences were found between sexes in sleep quality, excessive daytime sleepiness, or OSAHS risk.
Increased BMI and abdominal circumference are associated with narrower oropharyngeal dimensions and poorer sleep quality, contributing to higher daytime sleepiness and OSAHS risk, regardless of sex.
咽气道空间（PAS）的尺寸受某些因素影响，包括不同的面部形态模式和/或咽壁脂肪堆积，这可能会影响睡眠质量，并使个体易患阻塞性睡眠呼吸暂停低通气综合征（OSAHS）。
对下颌骨关系为I类、体重指数（BMI）>25kg/m²的个体的PAS尺寸和最大咽缩窄面积进行研究，并将其与颈部和腹部测量值以及睡眠质量数据相关联。通过Dolphin Imaging 11.95软件分析50名参与者（男女各25名，年龄18岁及以上，I类咬合，BMI>25kg/m²）的锥形束计算机断层扫描（CBCT）图像，以确定PAS面积和体积。参与者还测量了腰围和颈围，此外通过匹兹堡睡眠质量指数（PSQI）、爱泼华嗜睡量表（ESS）和柏林问卷（BQ）进行睡眠质量评估。
口咽尺寸、BMI和腹围之间存在显著相关性。较高的BMI与口咽体积减小有关。总PAS、口咽、下咽和最大咽缩窄值与白天过度嗜睡显著相关。总PAS减小也与OSAHS风险增加有关。在睡眠质量、白天过度嗜睡或OSAHS风险方面，男女之间未发现显著差异。
BMI和腹围增加与口咽尺寸变窄和睡眠质量较差有关，导致白天嗜睡增加和OSAHS风险升高，与性别无关。
