To evaluate the relationship between palatal morphology and pharyngeal airway morphology in patients who have obstructive sleep apnea (OSA) and compare with a nonsnoring and nonapneic control group.
Three-dimensional maxillary dental cast measurements from 25 OSA patients (6 women, 19 men) with a mean age of 41.5 (4.8) years, and 25 control group participants (14 women, 11 men) without any symptom of OSA with a mean age of 38.3 (3.7) were correlated with an analysis of pharyngeal area evaluated with lateral cephalograms. Intermolar and intercanine widths and palatal volumes were calculated on the dental casts, and the upper airway area measurements were performed on lateral cephalograms.
OSA patients had smaller oropharyngeal volume and upper airway when compared with controls (P < .001). Palatal area measurements were significantly smaller in OSA (P < .001). OSA patients had significantly narrower maxilla with smaller intermolar and intercanine widths (P < .001). A positive correlation was found between the palatal morphology and pharyngeal dimensions.
A significant correlation exists between palatal morphology and pharyngeal airway.
评估阻塞性睡眠呼吸暂停(OSA)患者的腭部形态与咽气道形态之间的关系,并与无打鼾和呼吸暂停的对照组进行比较。
对25例平均年龄为41.5(4.8)岁的OSA患者(6名女性,19名男性)和25例无OSA症状、平均年龄为38.3(3.7)岁的对照组参与者(14名女性,11名男性)的三维上颌牙模测量数据,与通过头颅侧位片评估的咽腔面积进行相关性分析。在牙模上计算磨牙间和尖牙间宽度以及腭部容积,并在头颅侧位片上进行上气道面积测量。
与对照组相比,OSA患者的口咽容积和上气道较小(P <.001)。OSA患者的腭部面积测量值明显较小(P <.001)。OSA患者的上颌骨明显更窄,磨牙间和尖牙间宽度更小(P <.001)。腭部形态与咽部尺寸之间存在正相关。
腭部形态与咽气道之间存在显著相关性。
