摘要
1985~1986年对60例口腔颌面部恶性肿瘤病人进行了临床和组织学观察。NdYAG激光的输出功率30~40W,光斑直径0.2~0.3cm,辐照时间5~10秒,距离0.5~1.0cm,能量密度2123~12732J/cm2。结果:治愈率86.0%。临床观察9年3例、8年8例、6年5例、5年2例、4年4例和3年以下27例没有复发;失败8例。结论:NdYAG激光适宜治疗年老体弱病人和高分化、外突型早期鳞状上皮癌病人。
cases of malignant tumors in the oral and maxillofacial regions were treated in the period of 1985 to 1996 were evaluated clinically and histologically. The output power of the Nd∶YAG laser was 30-40 W, light spot was 0 2-0 3 cm in diameter, the irradiation time was 5-10 s at a distance of 0 5-1 0 cm, and the energy density was 2 123-12 732 J/cm 2. The curative effect was 86 0%. Three cases were followed up for 9 a, 8-8 a, 5-6 a, 2-5 a, 4-4 a, and 27 cases were followed up for less than 3 a, recurrence has not been seen. Eight cases did not respond to laser therapy. Nd∶YAG laser is indicated in older and weak patients and in those the tumor is epithelial in nature, highly differentiated, exophytic type, and in early stage.
