著者们作为保存喉功能的手术方法,对声带癌及声门下癌,开展喉前庭下水平半喉摘除术。本手术法的基本原理是借假声带的实质性肥厚等,来代偿手术切除声带和下半部喉的功能。本术式的目的有三:①通过下半部喉的切除,可完全切除肿瘤。②特别是保存了甲状软骨上部1/3,既可防止术后性喉狭窄,以维持喉的气道功能,又有拔掉气管套管之可能。③由于保存会厌、假声带或按病情有的保存披裂软骨,使喉腔恢复了发音、吞咽、呼吸及防御功能。本术式的适应症是:声带癌,尚未侵及甲状软骨的声门下癌,声带癌作过喉裂开术或钴疗法后复发者,以及达第二气管环的声门以下的喉狭窄者。手术操作的基本程序分四个阶段:即在
The authors, as a surgical method of preserving laryngeal function, develop a laryngeal half-laryngectomy for vocal cord cancer and subglottic cancer. The basic principle of this surgical method is to take advantage of the substantial hypertrophy of the falsetto to compensate for the surgical removal of the vocal cords and the function of the lower half of the larynx. The purpose of this procedure are three: ① through the lower half of the laryngectomy, complete removal of the tumor. ② In particular, preserved upper thyroid cartilage 1/3, both to prevent postoperative sore throat in order to maintain laryngeal airway function, there is the possibility of pulling off the tracheal tube. ③ due to the preservation of epiglottis, false vocal cords or according to the condition of some preservation of the tear cartilage, the throat restored voice, swallowing, respiration and defense. Indications for this procedure are: vocal cord cancer, subglottic cancer that has not yet invaded thyroid cartilage, recurrent laryngeal rupture or vocal cord cancer after cobalt therapy, and laryngeal stenosis up to the glottis of the second tracheal ring . The basic procedure of operation is divided into four stages: that is
