鼻内进路的经鼻垂体瘤手术有2种术式：经鼻中隔-蝶窦进路和新发展的鼻内窥镜下经蝶窦进路。为探讨经鼻垂体瘤手术的改进，总结4例经鼻垂体瘤手术的情况，每种术式各2例。结果显示，采用鼻内窥镜能获得较宽而明晰的术野，能变换方位；由电视监视，可获得放大的图像而不必使用显微镜；简化进入蝶鞍及关闭进路的方法；减少手术创伤及并发症的发生，加快术后恢复。应用鼻内窥镜经蝶窦进路为垂体肿瘤摘除术较理想的术式。
There are two types of intranasal pituitary adenoma surgery: transnasal sphenoid sinus approach and newly developed transnasal endoscopic transsphenoidal sinus approach. In order to investigate the improvement of surgery for nasal pituitary tumors, 4 cases of nasal pituitary adenoma surgery were reviewed, 2 cases for each operation. The results show that the use of a nasal endoscope can achieve a wider and clearer operative field and can change the orientation; by television monitoring, an enlarged image can be obtained without using a microscope; the method of entering the sella and closing the approach can be simplified; and the surgical trauma can be reduced. And the occurrence of complications to accelerate postoperative recovery. Application of transnasal endoscopic sphenoid sinus approach for pituitary tumor removal is an ideal surgical procedure.
