摘要
目的运用核磁共振手段,研究无鼾正常人群戴入阻鼾器后上气道及周围软组织结构的影像学变化,探讨阻鼾器的作用机制,为临床了解阻塞性睡眠呼吸暂停综合征(OSAS)病因机制及对其阻塞部位定位诊断和制定适合患者的治疗方案提供科学依据。方法选择无鼾正常年轻人30例,在严格固位条件下进行核磁共振扫描。利用核磁共振设备的固有软件及特定公式进行测量和计算,分析戴入阻鼾器后上气道及周围软组织结构的影像学变化。结果获得阻鼾器戴入前后上气道各段及周围组织形态的线距、面积和体积等各项测量指标,经统计学分析,戴入阻鼾器后,上气道各段(鼻咽、腭咽、舌咽、喉咽)的平均截面积、最小截面积及体积明显增大;上气道各段宽度增加;气道周围软组织形态改变,软腭最大面积、软腭厚度及软腭长度、舌体长度、舌体最大面积减小,舌体高度增加,舌体更直立,软腭前移。结论戴入阻鼾器后上气道大小和形状可发生改变,提示阻鼾器是治疗OSAS的一种有效方法。
Objective To investigate the imagery changes of the upper airway and the surrounding soft tissues of local adults with non-apnea who used snore guard and to provide experimental data for the clinical diagnosis and treatment of obstructive sleep apnea syndrome （OSAS）. Methods Thirty students with non-apnea from Hebei medical university were chosen, and magnetic resonance imaging （MRI） was used to measure the changes of the upper airway and the surrounding soft tissues after snore guards were used. SPSS 10.5 software was used to analyze statistically. Results After the snore guard was put into oral cavity, the change of the average section and volume of the nasopharynx, the palatopharynx, the hypopharynx and the glossopharynx were statistically significant. The average sagittal size, the average horizontal size of the nasopharynx, the palatopharynx, the hypopharynx and the glossopharynx were increased statistically. The ratio of sagittal size, the horizontal size in the hypopharynx and the glossopharynx changed statistically important. There was a decrease of the soft palate, the shape, the height, and the length of the tongue, the difference was statistically significant. The results demonstrated that snore guard affected the upper airway mainly by changing the volume and the shape of the upper airway, there was an obvious increase of the pharynx. The results also showed that snore guard could increase the width （both sagittal and horizontal） of the upper airway and could change the shape of the sur- rounding soft tissues, which caused air way more smooth. Snore guard could make the indexes of soft palate and tongue change decreasingly, resulted in the straight stand up of the tongue and the forwardness of the soft palate. Conclusion Snore guard is an effective and convenient instrument for treating the patients with OSAS.
