治疗阻塞性睡眠呼吸暂停低通气综合征的咽成形术对嗅觉和味觉的影响

Effect of pharyngoplasty on olfactory and taste function in treating obstructive sleep apnea

目的：观察治疗阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的咽成形术对嗅、味觉的影响。方法：总结2005年4月～12月行咽成形术的39例患者中有嗅、味觉改变的主诉情况。结果：4例诉术后味觉改变，其中1例诉同时有嗅觉改变。例1嗅觉减退，酸和咸感觉丧失，2个月后部分恢复，对甜感觉过敏；例24种味觉均减退；例3对酸的感觉过度敏感；例4感痰中有酸和苦的感觉，属味幻觉。味觉改变的发生率达10％。结论：嗅觉和味觉的改变可能是咽成形术的并发症，影响患者的生活质量，必须给予重视，术前应向患者交代清楚，以免引起不必要的医疗纠纷。术中尽可能避免损伤味觉功能，如果发生嗅、味觉损伤，术后需给予处理。
