摘　　要：目的 :床突间隙 (CS)及周围结构进行显微解剖分型 ,为经该区的直接显微手术提供依据。方法 :用 3 0例成人头颅标本 ,在手术显微镜下对床突间隙及周围结构直接进行解剖观察和测量。结果 :床突间隙根据其对手术操作的影响和与颈内动脉 (ICA)的相互关系来看 ,侧位相可分为全ICA型 (68.3 3 % )、半ICA型 (2 6.67% )和无ICA型 (5 % )三型 ,冠状位相可分为ICA内侧型 (95 % )和ICA外侧型 (5 % ) ,其中大多数情况是全ICA型和ICA内侧型 ,而ICA外侧型的CS空间较小 ,影响手术操作。结论 :CS分型具体量化了CS的空间大小 。Objective: To provide anatomic basis for the direct microsurgical operation via clinoid space (CS) and sellar area by classifying microanatomical relations of their structures. Methods: Thirty adult cadaveric head pecimens were dissected in detail under operation microscope. Results: Based on the relationships of ACP and ICA, the CS was classified to three types in lateral view, namely the whole ICA (68.33%), half ICA (26.67%) and non-ICA (5%); there was 2 types of CS in coronal view, namely medial ICA (95%) and lateral ICA (5%). Conclusion: The space of CS was quantified by the classification. A microanatomical analysis of CS is provided for direct microsugical operation via cavernous sinus to parasellar regions.
