To explore the characteristic of lacrimal sac fossa on ESS and traditional maxillary operation, and to provide anatomy basis for the endoscopic endonasal dacryocystorhinostomy.
Twenty-three heads of adult cadaver specimens were examined including the shape, direction and the thickness of wall of lacrimal sac fossa.
The fossa is formed by the frontal portion of the maxillary bone and the lacrimal bone. The proportion of the frontal portion of the maxillary bone is bigger than the lacrimal bone. There is about 20 degrees between the rear wall of the fossa and the coronal plane.
Before the endoscopic endonasal dacryocystorhinostomy we should scan the anterior portion of the medial orbital wall so that we can understand the anatomy of the fossa and improve the effect of the surgery.
探讨鼻内镜手术（ESS）和传统上颌窦手术中泪囊窝的特点，为鼻内镜下泪囊鼻腔造口术提供解剖学依据。
对23个成人尸体头部标本进行检查，包括泪囊窝的形状、方向及壁的厚度。
泪囊窝由上颌骨额部和泪骨构成。上颌骨额部所占比例大于泪骨。泪囊窝后壁与冠状面呈约20度夹角。
在鼻内镜下泪囊鼻腔造口术前，应扫描眶内侧壁前部，以便了解泪囊窝的解剖结构，提高手术效果。
