二十年来,近全喉切除术(near-totallaryngectomy,NTL)逐渐展开,使部分中晚期喉癌、下咽癌一期获得发音。现将其发展近况作一概述。1 近全喉切除的解剖病理基础 喉不是简单的一块组织,而是由左右对称且来源不同的解剖部位(如左及右室带、左及右声带)共同组成的功能复杂的一个器官。癌往往发生在一侧或偏重一个解剖部位,之后逐渐扩展到其他解剖部位,即使晚期也很少有喉两侧各解剖部位都被侵及。
For two decades, near-total laryngectomy (NTL) has been gradually developed, so that part of the advanced laryngeal cancer, hypopharyngeal cancer, a pronunciation. Now an overview of its development. Anatomical and pathological basis of nearly total laryngectomy Laryngeal is not a simple piece of tissue, but from left and right symmetrical and different anatomical parts (such as the left and right ventricular zone, left and right vocal cords) a complex function of an organ. Often, cancer occurs on one side or on an anatomical site, then gradually to other anatomical sites. Even in advanced stages, there is very little dissection of each anatomical site on both sides of the larynx.
