A case of vocal-cord carcinoma situated in the anterior commissure of the larynx is presented. Indirect laryngeal endoscopy and biopsy evidenced a carcinoma in situ expanding on the anterior of the true vocal-cords with a subglottic expansion of about 1 cm. To obtain better visualization direct microlaryngoscopy was performed and the tumor was excised using the CO2-Laser. The anterior commissure and the adjacent parts of the true vocal-cords were excised. The false vocal-cords and adjacent tissues which were macroscopically suspicious for tumor infiltrations were exposed to the laser beam. --Later on a laryngectomy had to be performed because the tumor histologically had infiltrated adjacent tissues. The larynx was serially sectioned. Although the laser microsurgery results suggested destruction of the tumor an insufficient subglottic excision by vaporization was ascertained histologically. --This case suggests that tumors of subglottic expansion should not be excised by endolaryngeal laser microsurgery.
本文报告1例位于喉前联合的声带癌。间接喉镜检查及活检证实为原位癌，病变累及真声带前部，并向声门下扩展约1cm。为获得更好的视野，进行了直接显微喉镜检查，并用二氧化碳激光切除肿瘤。切除了前联合及真声带的相邻部分。对肉眼怀疑有肿瘤浸润的假声带及相邻组织进行了激光照射。——后来因肿瘤组织学上已浸润相邻组织而不得不进行喉切除术。对喉部进行了连续切片。尽管激光显微手术结果提示肿瘤已被破坏，但组织学检查确定声门下汽化切除不充分。——该病例提示，声门下扩展的肿瘤不应通过喉内激光显微手术切除。
