尽管治疗咽鼓管功能障碍的方法很多,但远非经常有效,需探寻新办法。为此作者对28例咽鼓管功能障碍、鼓膜完整者试用了低强度氦氖激光(-38)照射其咽鼓管软骨部起始端及咽口的粘膜。为将激光导入咽鼓管口,采用单导光纤维,其能量总消耗不超过22～25％。照射前先用金属咽鼓管导管通气,然后将导管用特殊装置(小夹子及额镜头带)固定,再经导管插入导光纤维。照射持续6分钟,导光纤维远端处的功率为50～60mW/cm~2,每日或隔日一次,5～10次为一疗程。照射前后,所有病人均纯音测听,用耳压计,鼓室功能测量,气声强度计(Pneumophonometer),咽鼓管风速
Although there are many ways to treat Eustachian tube dysfunction, it is far from always effective and new approaches need to be explored. To this end the author of 28 cases of eustachian tube dysfunction, eardrum integrity of the trial of low-intensity He-Ne laser (-38) irradiation of the eustachian tube cartilage at the beginning and pharyngeal mucosa. In order to guide the laser into the eustachian orifice, a single guide fiber is used, whose total energy consumption does not exceed 22-25%. Irradiation with metal eustachian tube before ventilation, and then the catheter with a special device (small clip and the amount of lens belt), and then through the catheter into the optical fiber. The irradiation lasts for 6 minutes, and the power at the distal end of the light guiding fiber is 50-60 mW / cm ~ 2, once daily or every other day, and 5 ~ 10 times as a course of treatment. Before and after irradiation, all patients were pure tone audiometry, with otolaryngology, tympanometry, breath sound intensity meter (Pneumophonometer), Eustachian tube wind speed
