目的：近几十年来，喉-气管重建术在修复儿童复杂的先天性或获得性喉气管狭窄方面取得了很大进展。本项目的目的是调查LTR术后患者队列中的诊断、手术干预类型和喉部表现之间的关系，以确定与充分的呼吸道保护和吞咽结果相关的因素。方法：对30名同时或近距离接受喉部和吞咽功能检查的呼吸道患者进行回顾性回顾。对数据进行分析，以检查与术后呼吸道保护和吞咽功能相关的因素。根据临床医生通过仪器检查判断的呼吸道保护(吸入和不吸入)的充分性，将患者分为两组。结果：数据分析显示，两组在喉部闭合、喉部闭合时间(相对于团注流量)和总体吞咽协调性3个关键参数上有统计学差异。结论：这些发现有助于了解呼吸道重建患者的喉部闭合模式以及吞咽时呼吸道保护对喉部基本功能的影响。文中还讨论了这些数据对该人群吞咽功能的影响。
Objectives: Laryngotracheal reconstruction (LTR) procedures for repair of complex congenital or acquired airway stenosis of the larynx and/or trachea in pediatric patients have advanced over recent decades. The aim of the present project was to investigate the relationships among diagnoses, type of surgical intervention, and laryngeal findings in a post-LTR patient cohort to identify factors associated with adequate airway protection and swallowing outcomes.Methods: A retrospective review of 30 airway patients undergoing simultaneous or close interval functional laryngeal and swallowing examinations was completed. Analyses of the data were performed to examine factors associated with postoperative airway protection and swallowing function. The patient cohort was separated into 2 groups according to the adequacy of their airway protection (aspiration and no aspiration) as judged by clinicians via instrumental examination.Results: Data analyses revealed statistically significant differences between the 2 groups for 3 key parameters: laryngeal closure, laryngeal closure timeliness (relative to bolus flow), and overall swallowing coordination.Conclusions: These findings contribute to the knowledge of laryngeal closure patterns present in patients undergoing airway reconstruction and the effect on the essential laryngeal function of airway protection during swallowing. Implications of the data for swallowing function in this population are discussed.
