泪囊鼻腔吻合手术是治疗慢性泪囊炎理想的手术方法,但是麻醉效果好环是手术顺利进行的关键。我们对8例患者采用了神经阻滞麻醉,收到良好效果。其方法介绍如下。 1,用牙科5号针从滑车下的眶内缘沿眶壁直接向后刺入约20mm,即达到滑车下神经。如再刺入10mm,即达筛前神经。可共注入1％普鲁卡因2.0ml注意针头直,稍离开骨膜,以免骨膜受伤及刺破筛前动脉。
Dacryocystorhinostomy is the ideal surgical treatment of chronic dacryocystitis, but good anesthesia ring is the key to the smooth operation. We used nerve block anesthesia in 8 patients and received good results. The method is described below. 1, with the No. 5 needle from the dentition of the orbital rim along the orbital wall directly piercing back about 20mm, that is, to reach the pulley under the nerve. If you pierce 10mm, that is, reach the anterior ethmoid nerve. Can inject a total of 1% procaine 2.0ml Note that the needle straight, slightly away from the periosteum, in order to avoid periosteal injury and puncture the anterior ethmoid artery.
