鞍结节脑膜瘤的手术入路各有优缺点及适应范围,手术入路的选择主要取决于肿瘤的大小、部位、与血管神经的关系以及肿瘤的血供情况。对于直径小于4 cm且窄基底的肿瘤,可采用经鼻蝶入路,而颅底修补是目前需处理的难题,各种经颅手术对于该类肿瘤亦可取得良好效果,但经颅手术中经眶上锁孔入路创伤更小。对于直径大于4 cm的肿瘤,经鼻蝶入路目前尚未成熟,各种经颅手术除外眶上锁孔入路均可达到目的。
The surgical approach of saddle nodular meningioma has its own advantages and disadvantages and its adaptability. The choice of surgical approach mainly depends on the size and location of the tumor, the relationship with the vascular nerves, and the blood supply of the tumor. For tumors with a diameter of less than 4 cm and a narrow basement, transsphenoidal approach can be used, and skull base repair is currently a difficult problem to be solved. Various kinds of transcranial surgery can achieve good results for such tumors, but in transcranial surgery The supraorbital keyhole approach trauma is smaller. For tumors larger than 4 cm in diameter, transsphenoidal approach is not yet premature, and various transcranial procedures except for supraorbital keyhole approach can achieve the goal.
