近来,我们采用二氧化碳激光烧灼咽后壁滤泡治疗慢性咽炎30例,疗效显著,现报告如下。 临床资料:本组男18例,女12例;年龄20～40岁。病史3个月至10年。全部病例咽后壁均见有淋巴滤泡增生,症状反复加重,经多种方法治疗效果不满意。 治疗方法:采用二氧化碳激光器,波长10.6um,输出功率30W可调式。患者取坐位,治疗前用1％地卡因做咽部粘膜表面麻醉,每5分钟1次,连喷3次。让患者张口,左手用压舌板压舌,充分暴露咽后壁,用氦—氖激光作指示,调试好二氧化碳激光聚焦光束在1mm左右,右手持激光刀头对准咽后壁淋巴 Recently, we use carbon dioxide laser cauterizing posterior wall follicular treatment of chronic pharyngitis in 30 cases, the effect is significant, are as follows. Clinical data: The group of 18 males and 12 females; aged 20 to 40 years old. History of 3 months to 10 years. All cases of pharyngeal wall are seen lymphoid follicular hyperplasia, symptoms repeatedly increased by a variety of methods are not satisfied with the treatment. Treatment: The use of carbon dioxide laser, wavelength 10.6um, 30W output power adjustable. Patients take seats, before treatment with 1% do lidocaine pharyngeal mucosal surface anesthesia, once every 5 minutes, and even spray 3 times. Let the patient mouth open, the left pressure tongue with tongue depressor, full exposure of the posterior pharyngeal wall, with helium-neon laser as a guide, debugging a good laser beam focused on the laser beam about 1mm, right hand holding the laser posterior pharyngeal lymph node
