通常经外部切口行泪囊鼻腔造口术。由于硬式鼻内窥镜的问世,可经鼻内直视下行鼻腔内泪囊区的手术。作者用此法行鼻内泪囊鼻腔造口术4例。方法:采用全麻,先用浸有1%利多卡因加1:100 000肾上腺素棉片收缩鼻腔血管,并在泪囊区直接注射少量同样的药液。经粘膜作一环形切口直至骨壁,切除此粘膜;再用刮匙或钻孔去骨,露出泪囊内侧壁;如可疑,可用泪囊探针插入囊内确定之。然后切开泪囊,并切除泪囊整个内侧壁,可置模扩张开口,但非属必须。结果,4例病人泪囊鼻腔造口通畅,无泪溢症状,效果良好。作者认为, Dacron nasal ostomy is usually performed via an external incision. Due to the advent of rigid nasal endoscopy, nasal direct vision down the nasal cavity dacryocyst area surgery. The author uses this method for intranasal dacryocystorhinostomy in 4 cases. METHODS: With general anesthesia, nasal vasoconstriction was contracted with 1% lidocaine plus 1: 100 000 epinephrine cotton and direct injection of a small amount of the same fluid in the dacryocyst area. The mucosa for a circular incision until the bone wall, remove the mucosa; and then curette or drill bone, exposing the inner wall of the lacrimal sac; if suspicious, can be used to determine the lacrimal sac probe inserted into the capsule. Then open the lacrimal sac, and the laparoscopic resection of the entire inner wall, can be modeled expansion dilation, but not a must. Results, 4 patients dacryocystorhinostomy unobstructed, no symptoms of spilled tears, the effect is good. the author thinks,
