      【摘要】 扩大额下入路较传统额下入路及眶上锁孔入路具有暴露范围广、术野清楚、不易损伤神经、术后复
发率低、便于颅底重建等特点，该入路治疗前颅窝底缺损、脑脊液漏方法可靠。与传统入路相比此入路取下了眉
弓，去除了部分眶顶板，术野暴露更接近颅底，对额叶牵拉极少，缩短了手术操作距离，有利于前颅底、颅底中央
部肿瘤的切除，特别是大型肿瘤的切除。

【Abstract】 Extended subfrontal approach, compared with traditional subfrontal approach and supraorbital
keyhole approach, has the advantages of wide exposure, clear operative field, low recurrence rate, which is not prone
to injure the nerve and easy to reconstruction the skull base. This method is reliable to treat anterior skull-base defect
and leakage of cerebrospinal fluid. It took down the superciliary arch and part of orbital roof. The exposure of the oper-
ative field was more close to the skull base, and the retraction of the frontal lobe was very few. This approach shortens
the operation distance, and benefits the resection of anterior skull base and central skull base tumors, especially large
tumors.
