作者采用尸头制作含鼻窦和眶的大块切片,观察了鼻窦、眶及筛板的互相关系,并指出鼻窦内窥镜手术(SES)中的解剖标志和安全平面,借以使术者了解此术并发症的发生从而以避免。尸头6个分12块,每块均有颅前窝底、面部皮肤和颧骨。蝶鞍切片含视神经交叉,大块一侧有鼻中隔和筛板,另一侧为鼻甲。制作后按标准定位作冠状和矢状切片观察。筛窦上壁:中鼻甲垂直板附丽处为该壁关键结构,内侧顶筛板较厚,外侧和筛房顶的额骨板在筛房和眶上变薄,此部筛房近硬脑膜。术中对中鼻甲用扭力或正对筛窦顶的筛房间隔
The authors used cadaver heads to make large sections of the sinuses and orbits, observed the relationship between the sinuses, orbital and sieve plates, and pointed out anatomic landmarks and safety planes in sinus endoscopic surgery (SES) so that surgeons could understand this The occurrence of complications to avoid. Cadaver 6 points 12, each have a skull base, facial skin and cheekbones. Sella slice with optic nerve cross, big side of the nasal septum and sieve plate, the other side of the turbinate. After making the standard positioning for coronal and sagittal section observation. Ethmoid sinus wall: the middle turbinate vertical plate attached to the Department of the wall of the key structure, thicker medial top sieve, outer and top of the sieve roof pancreas thinning in the vestibule and supraorbital, the Ministry of sieve nearly dural. Intraoperative use of torque on the middle turbinate or right of the ethmoid sinus top of the screen room interval
