所有检查喉的方法都有其盲区或不足。在临床上放射学检查等方法难以诊断的区域,如环状所有检查喉的方法都有其盲区或不足。在临床上放射学检查等方法难以诊断的区域,如环状软骨上缘、构状软骨、弹力圆稚及声门旁区、喉的计算机断层扫描(简称CT)有最大的正确性。适应症:喉密的保守性手术有两大类:一是水平的部分喉切除术,横切口作于真假声带之间,保留真声带及声门下区。二是垂直部分喉切除术,作垂
All methods of checking the throat have blind spots or deficiencies. In areas where clinical methods such as radiological examination are difficult to diagnose, for example, all methods of examining the larynx in the ring have blind spots or deficiencies. In areas where clinical diagnostic radiographs and other methods are difficult to diagnose, such as the upper edge of cricoid cartilage, orthochondral cartilage, elastic palpation, paraglottic region, computed tomography scan of the larynx (CT for short) has the greatest accuracy. Indications: There are two major categories of conservative surgery for laryngeal herniation: First, partial laryngectomy, horizontal incisions between true and false vocal cords, preservation of the true vocal cords and subglottic regions. The second is vertical partial laryngectomy.
