作者们自1951年以来共施行467例声门上喉切除术,男性430例,女性37例;平均年龄51岁。其中Ⅱ期病例占全部患者的60%;所以无T_3病例,乃因按照UICC 1969和1974年所公布的定义,由于声门上T_3肿瘤最不常见,且在所定的分类中,凡杓状软骨和/或杓会厌、咽会厌皱襞和/或会厌溪及舌根,和/或会厌前间隙受侵全是T_4的指征。N-(N_0,N_(1a),N_(2a))组比N+(N_(1b),N_(2b),N_3)组多,为323∶84。在全部N_0和N_(1a)病例中有13.16%组织学证实有癌转移,故在实践中应尽可能对所有声门上癌病例行双侧选择性或根治性颈清扫术。声门上喉切除可扩大切除包括一个杓状软骨、杓会厌皱襞、舌根及邻近的梨状窝内侧壁等组织,保存其声带突并在中线位将之缝合固定于环状软骨。这被称为扩大的声门上喉切除术。这种技术可使很多病例的预后得到改善,并能防止后遗发音及吞咽障碍。全部病例的五年生 The authors have performed 467 cases of supraglottic resection since 1951, with 430 males and 37 females; the average age is 51 years old. Phase II cases accounted for 60% of all patients; therefore, there were no cases of T_3 because it was defined according to the definitions published in UICC 1969 and 1974, because the T3 tumors on the glottis were the least common, and in the defined classification, the arytenoid cartilage And/or epiglottis, epiglottis folds and/or epiglottis brook and tongue base, and/or epiglottis frontal space invasion are all indications of T_4. The N-(N_0,N_(1a),N_(2a)) group was more than the N+(N_(1b),N_(2b),N_3) group and was 323:84. In all cases of N_0 and N_(1a), 13.16% of histologically confirmed histological metastases, it should be possible in practice to perform bilateral selective or radical neck dissection on all patients with supraglottic cancer. The supraglottic laryngectomy can be used to expand the resection including a arytenoid cartilage, epiglottis folds, tongue bases, and adjacent piriform fossa medial sidewalls, and preserves its vocal folds and sutures it to the cartilage at the midline. This is called augmented supraglotticectomy. This technique can improve the prognosis of many cases, and can prevent postoperative pronunciation and swallowing disorders. Five years for all cases
