声门癌致声带固定或运动显著受限一般和甲杓肌受累有关,常有声门下侵犯,少数情况因肿瘤沿声带上面向外扩展至内软骨膜,使声带受限或固定,此种情况的声带癌的治疗尚有争议。Kirchner主张作选择性的传统半喉切除术,2年生存率为60%,并指出失败常系下缘切除不足所致。本文报告一组传统或扩大半喉切除病例,声门下扩展大于5 mm者则切除部分环状软骨。全组26例,15例声带固定,11例运动显著受限。传统半喉切除术切除一侧邻近声带的甲状软骨翼,为增加声门下切除的边缘,有时切开覆盖环状软骨的粘膜,将其从软骨分离。扩大半喉切除术切除环状软骨上方的一部分,代之以软骨移植。切除范围包括环状软骨外侧上方的75%,向 The fixation of glottic cancer to the vocal cords or significant limitation of movement is generally related to the involvement of hyperthyroid muscles, often with subglottic invasiveness. In a few cases, the tumor extends along the vocal cords to the inner cartilaginous membrane and restricts or fixes the vocal cords. The treatment of vocal cord cancer is still controversial. Kirchner advocated selective traditional hemi-laryngectomy with a two-year survival rate of 60%, and pointed out that failure was often caused by insufficient resection of the inferior margin. This article reports a group of conventional or extended hemi-laryngectomy cases, where a subglottic extension greater than 5 mm results in the removal of a portion of annular cartilage. There were 26 cases in the whole group, 15 cases were fixed in vocal cords, and 11 cases were significantly limited in exercise. Traditional hemi-laryngectomy removes the thyroid cartilage wings on the side adjacent to the vocal cords. To increase the margin of subglottic resection, sometimes the mucosa covering the cricoid cartilage is dissected and separated from the cartilage. An enlarged half-laryngectomy resection of the upper part of the annular cartilage was replaced by cartilage transplantation. The resection range included 75% of the lateral superior side of the cartilage.
