Aspiration is the major problem in deglutition associated with conservation laryngeal surgery. Closure of the glottic sphincter, depression of the epiglottis over the laryngeal inlet, elevation of the thyrohyoid complex under cover of the base of the tongue and appropriate relaxation of the cricopharyngeal muscle to permit unobstructed passage of food into the esophagus are important mechanisms that prevent food from entering the trachea. Partial laryngeal surgery can interfere with one or a combination of these mechanisms. Analysis of the records of all evaluable patients who underwent horizontal supraglottic resections from January 1976 to June 1981 was undertaken. The incidence of deglutition problems is reported. In addition, the effects of resection or preservation of the hyoid, arytenoid, base of tongue and branches of the vagus and the effect of cricopharyngeal myotomy upon ultimate swallowing function are analyzed.
误吸是与保留喉手术相关的吞咽过程中的主要问题。声门括约肌的关闭、会厌在喉入口上方的压低、甲状舌骨复合体在舌根覆盖下的抬高以及环咽肌的适当松弛以允许食物无障碍地进入食管，这些都是防止食物进入气管的重要机制。部分喉手术可能会干扰这些机制中的一种或多种。对1976年1月至1981年6月期间接受水平声门上切除术的所有可评估患者的记录进行了分析。报告了吞咽问题的发生率。此外，还分析了舌骨、杓状软骨、舌根和迷走神经分支的切除或保留的影响以及环咽肌切开术对最终吞咽功能的影响。
