我科与广州市玻璃搪瓷研究所协作,把光导纤维偶合在氦氖激光器上,治疗渗出性中耳炎60例77耳,有效率达98.7％,现报道如下。一、方法 1.光导纤维偶合氦氖激光器: 采用光导纤维直通型与分叉型传光束,并偶合在低功率(6～8毫瓦)的氦氖激光器上,其透射率为42～44％。直通型光导纤维管长为60cm,管口直径0.4cm。分叉型(即Y型)管长80cm,管口直径0.3cm。 2.治疗时间与方法: 每天照射激光一次,每次10分钟,15天为一疗程。照射治疗前,应先观察耳膜变化和中耳积液情况,抽积液后照射激光,如少量积液时,可免穿刺,因大多数患者照射激光后,能自行
Our department and the Guangzhou Institute of glass enamel collaboration, the optical fiber coupled to the He-Ne laser, the treatment of exudative otitis media 60 cases 77 ears, the effective rate of 98.7%, are reported below. I. Method 1. Optical fiber coupling He-Ne laser: using optical fiber through type and bifurcated type beam, and coupled to the low-power (6 ~ 8 milliwatts) of He-Ne laser, the transmittance of 42 to 44% . Through-type optical fiber tube length of 60cm, nozzle diameter 0.4cm. Bifurcated (that is, Y-type) tube length 80cm, nozzle diameter 0.3cm. 2. Treatment time and methods: laser irradiation once a day, every 10 minutes, 15 days for a course of treatment. Irradiation before treatment, should be observed changes in the eardrum and middle ear effusion, pumping fluid after laser irradiation, such as a small amount of effusion, can be puncture-free, because most patients with laser irradiation, to their own
