目的 :探讨阻塞性睡眠呼吸暂停综合征 (OSAS)患者舌体与下齿牙合面、舌根和悬雍垂相互关系的变化在OSAS的发病意义。方法 :经PSG确诊的OSAS患者共 2 1例 ,单纯打鼾 2 5例 ,正常成年人 30例 ,观测舌体与下齿的关系和悬雍垂与舌根的关系 ,比较 3组间的差别。结果 :正常对照组舌体大多低于下齿牙合面 ,张口平静呼吸可见悬雍垂尖端 ;单纯打鼾组多数舌体与下齿牙合面平齐 ,需发音时才可见到悬雍垂尖端 ;OSAS组患者舌体多高出下齿牙合面 ,发音时亦难见到悬雍垂尖端。 3组间比较差异显著。结论 :舌体增大、软腭组织增厚与悬雍垂延长导致咽部狭窄是OSAS发生的重要原因。
Objective: To investigate the relationship between the change of tongue surface and inferior occlusal surface, tongue base and uvula in obstructive sleep apnea syndrome (OSAS) patients in the pathogenesis of OSAS. Methods: A total of 21 OSAS patients were diagnosed by PSG. There were 25 cases of simple snoring and 30 cases of normal adults. The relationship between tongue and lower teeth and uvula were observed. The differences between the three groups were compared. Results: The tongue of the normal control group was mostly lower than the occlusal surface of the lower teeth and the mouth of the mouth was calm and breathable. The simple tongue-snoring group had most of the lingual bodies flush with the lower teeth, ; OSAS group of patients with higher than the tongue under the gear surface, uvula pronoun is also difficult to pronounce the tip. 3 groups were significantly different. Conclusion: The increase of the tongue, the thickening of soft palate and the extension of uvula lead to pharyngeal stenosis is an important reason for OSAS.
