泪囊鼻腔吻合术是治疗慢性泪囊炎的理想手术.但由于术中对鼻粘膜的某些失误致手术失败的为数不少.作者改进了鼻粘膜麻醉方法,取得了较满意的效果.介绍如下:方法术前鼻腔冲洗干净,喷1%麻黄素液,共3次.手术进行到开骨窗时,在筛骨前缘薄骨部位用血管钳开一骨孔.用1%地卡因肾上腺素棉片从骨孔处填入鼻骨与粘膜之间,边填入边分离鼻粘膜,同时扩大骨窗.亦可在泪前嵴处凿一骨缝,能容纳虹膜恢复器为好.用1%地卡因肾上腺素液滴入骨缝处,用虹膜恢复器从骨缝处轻轻将鼻粘膜向鼻中隔方向分离.分离后将棉片填入,鼻粘膜被压向鼻中隔.咬骨钳开骨窗.
Dacryocystorhinostomy is an ideal operation for the treatment of chronic dacryocystitis, but due to some mistakes in the operation of the nasal mucosa resulting in a large number of failures. The authors improved nasal mucosal anesthesia and achieved satisfactory results. As follows: Methods Preoperative nasal irrigation was clean, spray 1% ephedrine solution, a total of 3. Surgery to the open bone window, open a bone hole in the thin bone parts of the anterior ethmoid bone using vascular clamps with 1% Adrenaline cotton pad filling the bone between the nasal bone and mucosa, while filling the separation nasal mucosa, while expanding the bone window. Can also be cut in the tears before crevasse crevices, can accommodate the iris recovery is better. 1% dexamethasine adrenaline droplets into the suture, the iris restorer gently from the seams nasal septum nasal septum gently separated after filling the cotton pad, the nasal mucosa was pressed to the nasal septum. Open the bone window.
