颞下经硬膜外锁孔入路显微解剖学研究

Microanatomical study of the subtemporal keyhole approach

目的应用锁孔入路的新理念进行显微解剖学研究,为临床应用颞下经硬膜外锁孔入路提供依据。方法模拟颞下经硬膜外锁孔入路,对10具经10%甲醛固定的成人尸头标本在显微镜下进行观察并测量显露的解剖结构。结果颞下经硬膜外锁孔入路可以充分暴露海绵窦外侧壁及其内部结构。结论颞下经硬膜外锁孔入路可用于累及海绵窦肿瘤的手术治疗。

Objective To investigate the feasibility of subtemporal transepidural keyhole approach. Methods The new keyhole approach was imitated in ten adult cadaverie heads fixed in 10% formalin. Under operative microscope, the anatomic structures were observed and important structures were measured after the cavernous sinus was exposed. Results The approach could provide a full visualization for the lateral structures and internal contents of the cavernous sinus. Conclusion It is feasible to perform the subtemporal transepidural keyhole approach on operation aiming at lesions involved in the cavernous sinus.
