摘要
目的观察后组筛窦、蝶窦和视神经管的相互关系,为鼻窦病变的CT诊断和临床应用提供依据。材料与方法对60例正常人筛窦、蝶窦和视神经管进行CT扫描,39例行横断层加冠状扫描,21例于横断层扫描后加冠状扫描。结果根据后组筛窦蝶窦的位置关系分为蝶前型(49.2％),蝶侧型(36.7％)和蝶上型(14.2％)。根据后组筛窦与视神经管的位置关系可以分成:管前型(46.7％),管口间型(23.3％),管后型(13.3％),蝶鞍型(10％)和管周型(6.7％)。结论 CT扫描是观察副鼻窦和视神经管最重要方法,能为临床副鼻窦疾病手术提供依据。
Objective To study the anatomical relationship between ethmoid sinus, sphenoid sinus & optic canal, & to provide data for CT diagnosis & clinical usefulness of paranasal sinus diseases. Materials & Methods CT scans of ethmoid & sphenoid sinuses were taken in 60 normal individual, All the subjects were porformed axial & cornal CT scans (n = 60) . Results: According to the relation of posterior ethmoid sinus (PES) to sphenoid sinus. The PES were divided as follows: antero - sphenoid (49.2%), latero- sphenoid (36.7%) and supero- sphenoid (14.2%) types. Based on the relation between posterior ethmoid sinus & the optic canal, the PES were divided into antero - canal (46.7%) intero - holes (23.3%), posterocanal (13.3%), sellar (10%) & circumcanal (6.7%) types, respectively. Conclusion For obcervating the anatomical relationship between ethmoid sinus, Sphenoid sinus & optic canal, CT scan was important, that could offer useful anatomical data for clinical & surgery in paranasal sinus lesions.
