几乎自从有了全喉切除术以来,就知道在下咽和气管之间作一瘘管以恢复语言。至近年,已发展了多种手术方法,成功地解决了气流单向流过细小瘘管而不至误吸,但维持瘘管长期通畅的问题却未获解决。后来Singer-Blom报告了一种简单的硅胶瓣膜喉发音装置,然而此装置与Panje(1981)首创的发音钮扣一样,尚有一定的不足。1980年作者研制了一种硅胶双凸缘的Groningen喉发音装置,它克服了前二者的缺点。手术操作:(1)全喉切除术后:全麻下将食管镜放于气管口下2 cm,转动180°使其斜面紧贴于气管后壁之后,用一特制的穿刺器于气管瘘
Almost since there has been total laryngectomy, it has been known to make a fistula between the hypopharynx and the trachea to restore the language. In recent years, a variety of surgical methods have been developed to successfully solve the problem of unidirectional airflow through small fistulas without aspiration, but the problem of maintaining long-term fistula closure remains unresolved. Singer-Blom later reported a simple silicone valve laryngeal device, which, however, had the same disadvantages as the first Panje (1981) pronunciation button. In 1980, the authors developed a silicone double-flanged Groningen laryngoscope that overcomes the disadvantages of the former two. Surgical operation: (1) after total laryngectomy: Under general anesthesia esophagoscopy placed in the trachea mouth 2 cm, rotated 180 ° so that the bevel close to the posterior wall of the trachea, with a special puncture in the tracheal fistula
