近几年来,CO_2激光束作为外科手术器械在不同的医学领域越来越受到人们的重视。由于其输出能量仅作用于表面,尤其适用于上呼吸道和消化道的手术。自1985年至1988年以来,作者用CO_2激光治疗20例腭部肿瘤的患者。12例女性和8例男性,年龄16岁～78岁。首先在镜下可见肿瘤边界5mm～10mm处标出CO_2激光切除线,在正常组织内慢慢切除肿瘤.直径大于0.5cm的血管偶尔需钳夹止血。20例患者中,12例良性肿瘤,最多见是多形性腺瘤,8例恶性肿瘤均为鳞状细胞癌。1/3肿瘤局限于硬腭1/3发生在软腭,1/3位于软硬腭交界处.切除最大的肿
In recent years, CO 2 laser beam has attracted more and more attention as a surgical instrument in different medical fields. Because its output energy only acts on the surface, it is particularly suitable for upper airway and digestive tract surgery. Since 1985 to 1988, the authors used CO 2 laser to treat 20 patients with axillary tumors. 12 women and 8 men, aged 16 to 78 years. Firstly, the CO2 laser ablation line was marked at the tumor boundary from 5mm to 10mm, and the tumor was slowly resected in normal tissue. Vascular vessels larger than 0.5cm in diameter were occasionally required to clamp the hemostasis. Among 20 patients, 12 were benign tumors, the most common being pleomorphic adenomas, and 8 malignant tumors were all squamous cell carcinomas. 1/3 of the tumors were confined to the soft palate in 1/3 of the hard palate and 1/3 were located at the junction of the soft palate and the hard palate.
