临床上通常把喉部肿瘤分为声门上型、声门型和声门下型,是根据其原发部位来分的,各又有其解剖学上的特点,影响其生长和扩展。据此,Alonso(1947)首先采用了声门上水平喉切除术来治疗声门上喉癌,甚至当肉眼看来肿瘤已紧邻声门时,其切除面的下界也仅切到声带上缘。Bocca(1976)根据随访的发现,认为“从肿瘤学观点看来,这是一种唯一保留喉基本功能的好手术”。
Clinically, laryngeal tumors are usually classified into supraglottic, glottic, and subglottic, and are classified according to their primary site, each of which has its anatomical characteristics, affecting its growth and expansion. Accordingly, Alonso (1947) first used supraglottic horizontal laryngectomy to treat supraglottic laryngeal cancer. Even when the tumor was close to the glottis, the lower boundary of the resected surface was only cut to the upper edge of the vocal cord. Bocca (1976), based on follow-up findings, concluded that “From an oncology point of view, this is a good operation to preserve the basic function of the larynx.”
