声门癌T_(1a)型(UICC分类)大部分可经放疗冶愈,放疗后多数发声接近正常。但放疗仍有一些缺点,如疗程长、喉干、咽喉炎,偶有严重副作用。且可能出现放射性癌。肿瘤复发即不能再次放疗。而激光疗法的治愈率接近放疗者。为探讨激光治疗后患者的发声功能,作者分析了声门癌31例,均T_(1a)型。男27,女4。年龄42～84岁,平均61.3岁。单纯放疗14例;单纯激光治疗或激光与放疗联用者17例按激光手术去除声带深度分为6度:1度为牯膜固有层的表浅部位的一部分;2度为整个粘膜固有层表浅部位;3度为部分声韧带;4度为整个声留带;5度为部分声带肌;6度为整个声带肌。术后3个月始行发声功能测定。此时
Most of the glottic cancer T_(1a) type (UICC classification) can be cured by radiotherapy, and most of the vocalizations after radiotherapy are close to normal. However, radiotherapy still has some shortcomings, such as long course of treatment, dry throat, pharyngitis, and occasional serious side effects. And there may be radioactive cancer. Recurrence of the tumor can not be re-radiotherapy. The cure rate of laser therapy is close to that of radiotherapy. In order to discuss the vocal function of patients after laser treatment, the author analyzed 31 cases of glottic carcinoma, all of which were type T1(1a). Male 27, female 4. Age 42 to 84 years old, average 61.3 years old. 14 patients were treated with radiotherapy alone; 17 patients were treated with laser or laser and radiotherapy were divided into 6 degrees according to the depth of vocal cords by laser surgery: 1 degree was a part of the superficial part of the lamina propria; 2 degrees was the entire lamina propria. Shallow; 3 degrees for the partial acoustic ligament; 4 degrees for the entire acoustic band; 5 degrees for the partial vocal cord muscle; 6 degrees for the entire vocal cord muscle. The vocal function was measured 3 months after operation. at this time
