作者用氦氖激光器(?)1治疗鼻窦炎64例,年龄20～64岁,急性上颌窦炎17例,慢性上颌窦炎36例,急性上颌窦和额窦炎11例。为使激光直接照射窦粘膜,作者设计了光学接头,并改制上颌窦穿刺针:由短(33mm)长(80mm)两部分组成,用螺丝口连接;经下鼻道穿刺上颌窦,灌洗排脓;然后经过穿刺针管腔放入光导管,用散焦激光器照射窦腔,距离20mm,功率密度0.8～10mW/cm~2,照射2～10分钟。激光治疗后把穿刺针的延长部分扭开取出,短小部分保留并固定在穿刺孔,使不致脱出或落入上颌窦,直到疗
The authors used helium-neon laser (?) 1 treatment of sinusitis in 64 cases, aged 20 to 64 years, 17 cases of acute maxillary sinusitis, chronic maxillary sinusitis 36 cases, acute maxillary sinus and frontal sinusitis in 11 cases. In order to direct the laser irradiation of the sinus mucosa, the author designed an optical connector and reformed the maxillary sinus puncture needle: it consists of a short (33mm) long (80mm) two parts connected by a screw mouth, a maxillary sinus Pus; and then into the light pipe through the lumen of the puncture needle, the sinus cavity is irradiated with the defocus laser, the distance is 20mm, the power density is 0.8-10mW / cm2, and the irradiation is performed for 2 to 10 minutes. After the laser treatment, the extended part of the puncture needle is taken out and the short part is retained and fixed in the puncture hole so as not to come off or fall into the maxillary sinus until treatment
