Abstract：
OBJECTIVE: To assess the role of laryngo-tracheo-bronchoscopy in children with obstructive sleep apnoea by identifying airway abnormalities at surgery, that occur separately or in addition to adenotonsillar hypertrophy, and examining the correlation with respiratory parameters.
METHODS: A retrospective study was conducted of children with obstructive sleep apnoea who underwent laryngo-tracheo-bronchoscopy intra-operatively, performed by a single ENT surgeon from February 2016 to July 2019. Pre- and post-operative minimum oxygen saturation, apnoea-hypopnoea index, and oxygen desaturation index were recorded.
RESULTS: Sixty-five children were identified; 34 were aged less than three years and 31 were aged three years or more. 77 per cent and 13 per cent respectively had an airway abnormality; the t-test showed a significantly higher mean oxygen desaturation index and lower mean minimum oxygen saturation pre-operatively compared to children without an airway abnormality.
CONCLUSIONS: An update of the surgical pathway for children aged less than three years with obstructive sleep apnoea is required to include laryngo-tracheo-bronchoscopy intra-operatively. A t-test analysis of the pre-operative respiratory parameters suggests that airway abnormalities contribute to obstructive sleep apnoea severity.

摘要：
目的：通过识别手术中的气道异常来评估喉气管支气管镜在阻塞性睡眠呼吸暂停患儿中的作用，单独发生或除了腺样体扁桃体肥大之外，并检查与呼吸参数的相关性。
方法：对阻塞性睡眠呼吸暂停患儿进行回顾性研究，2016年2月至2019年7月由一名耳鼻喉科外科医生进行。术前和术后最低氧饱和度,呼吸暂停-呼吸不足指数,记录氧饱和度指数。
结果：确认了65名儿童；34名年龄在3岁以下，31名年龄在3岁以上。分别有77％和13％的人患有气道异常；t检验显示，与无气道异常的儿童相比，术前平均氧饱和度指数明显较高，平均最低氧饱和度较低。
结论：需要更新3岁以下儿童阻塞性睡眠呼吸暂停的手术途径，包括术中喉气管支气管镜检查。术前呼吸参数的t检验分析表明，气道异常会导致阻塞性睡眠呼吸暂停的严重程度。
