目的探讨影响支撑喉镜下声门区暴露的相关因素,为术前评估提供参考。方法对53例声带息肉患者于支撑喉镜术前采集可能影响声门区暴露的相关临床数据,包括:性别、年龄、体重、甲颏间距、张口度、头颈屈伸度、舌背高度评估。建立数据库,结合患者支撑喉镜术中声门区暴露的情况对上述影响因素进行统计学分析。结果单因素分析显示体重、甲颏间距、头颈屈伸度、舌背高度评估与术中声门区暴露相关,差异有统计学意义。经多因素统计分析甲颏间距、头颈屈伸度、舌背高度评估与术中声门区暴露相关,差异有统计学意义。结论患者头颈部解剖特点影响支撑喉镜下声门区的暴露,术前可根据相关参数预测声门区暴露情况。
Objective To explore the influencing factors of the exposure of the glottis area under the support laryngoscope and to provide a reference for preoperative evaluation. Methods Fifty - three patients with vocal cord polyps were collected before the operation of the laryngoscope. Relevant clinical data that may affect the glottic exposure were collected, including gender, age, body weight, distance between chinchillas, mouth opening, head and neck flexion and extension, and tongue back height. Establish a database, combined with patient support laryngoscopy glottic exposure of the above factors were statistically analyzed. Results Univariate analysis showed that body weight, distance between chinchilla, head and neck flexion and extension, tongue height were correlated with glottic exposure, the difference was statistically significant. Multivariate statistical analysis of chin interval, head and neck flexion and extension, tongue height assessment and glottic exposure, the difference was statistically significant. Conclusion The head and neck anatomy of the patients affected the exposure of the glottis area under the support laryngoscope. The exposure of the glottis area could be predicted according to the relevant parameters before operation.
