精通鼻窦解剖对于耳鼻喉科医生极为必要,但在狭窄的空间研究复杂的毗邻结构比较困难。可将筛窦比作一个有四个壁和两个开口的火柴盒,其顶为筛顶,侧壁为纸样板,内壁是中鼻甲,后壁是蝶窦前壁,前壁和下壁是敞开的,将盒自前到后分成A、B、C三个区域。A区指中鼻甲前上部分,这一空间最狭窄,上壁的筛顶骨板菲薄,容易进入前颅凹。侧方纸样板与眶内相隔,此区域包括额隐窝、鼻丘、筛板、前筛动脉、鼻泪管、纸样板、钩突、漏斗、上颌窦开口及筛泡。额窦开放术必须切除鼻丘或额隐窝。B区指中鼻甲后外侧部,即基底板后部,是手术中确定筛顶和纸样板的重要位置。筛顶的测量可用探针,大约与鼻底成 Proficiency in sinus anatomy is essential for otolaryngologists, but it is difficult to study complex adjacent structures in confined spaces. The ethmoid sinus may be compared to a matchbox with four walls and two openings, the top of which is a sieve top, the side wall is a paper template, the inner wall is the middle turbinate, the posterior wall is the anterior sphenoidal wall, the anterior wall and the inferior wall are Open, the box from front to back into A, B, C three regions. A area refers to the middle part of the middle turbinate, the narrowest of the space, the upper wall of the sieve plate bone meager, easy to enter the anterior fossa. Side of the paper template and orbital septum, this area including the frontal recess, nose, sieve, anterior sieve artery, nasolacrimal duct, paper template, uncinate, funnel, maxillary sinus openings and bubble. Frontal sinus surgery must be removed nasal or frontal crypt. Area B refers to the posterior part of the middle turbinate, which is the posterior base plate, which is an important site for determining the shape of the sieve top and the paper template during surgery. Top of the probe can be used to measure, about the end of the nose into
