It has been well established that supraglottic laryngectomy is an effective treatment of laryngeal cancer arising above the vocal cords with cure rates equaling total laryngectomy. Although there is preservation of a near normal voice after supraglottic laryngectomy, chronic aspiration occurs in some patients particularly after extended supraglottic laryngectomy or when there is associated compromised pulmonary function. During normal deglutition, the epiglottis serves to divert food to the pyriform fossae and partially covers the inlet to the airway. These important functions can be accomplished after supraglottic laryngectomy by reconstructing a neoepiglottis from an epiglottic remnant whenever one third or more of the epiglottis can be preserved which is microscopically free of tumor. Our results in 14 patients have shown no clinically significant aspiration after epiglottic reconstruction.
声门上喉切除术是治疗声带以上喉癌的有效方法,其治愈率与全喉切除术相当,这一点已得到充分证实。尽管声门上喉切除术后可保留接近正常的嗓音,但部分患者会出现慢性误吸,尤其是在扩大声门上喉切除术后或伴有肺功能受损时。在正常吞咽过程中,会厌将食物导向梨状窝,并部分覆盖气道入口。只要能保留三分之一或更多的会厌且显微镜下无肿瘤残留,就可以利用会厌残端重建新的会厌,从而在声门上喉切除术后完成这些重要功能。我们对14例患者的研究结果表明,会厌重建术后无具有临床意义的误吸发生。
