摘要
在30侧成人头部正中矢状剖面标本上,以前鼻棘为基准,对泪囊下部进行了定位。并以下鼻甲长度为基准,测算了鼻泪管下口与下鼻甲的比例。泪囊下部内侧壁不被中鼻甲所覆盖的占83%(25例);被覆盖的占17%(5例)。鼻泪管下口有21例位于下鼻甲前1/3段,9例位于中1/3段。作者提出了鼻腔内窥镜泪囊造孔术的手术要点及上颌窦造孔的安全部位。
Based on dissection and measurement on the sagittal median plane in 30 adult head speci-mens,the inferior part of dacryocyst and the infeior orifice of nasolacrimal duct were located re-spectively in accordance with the anterior nasal spine and the inferior turbinate.83% of the medi-al wall of dacryocysts are not coverred by middle turbinate and 70% of the inferior orifices of na-solacrimal ducts open at the anterior 1/3 of the inferior turbinate,while the remaining 30% openat the middle part.Safe area and key operation approach in dacryocystostomy and maxillary sinusfenestration by endoscopic surgery were discussed.
