本文作者使用直接经蝶窦入路作垂体肿瘤的颅外标准入路,对150余例进行了手术,证明该入路速度快,安全有效,对正常组织损伤少。鼻腔虽然有弹性,但要使外鼻伸展到能利于器械操作还是有限的。所以常常需在鼻孔与面颊相接处作一半在鼻孔内,一半在鼻孔外的短外侧切口。术前常规摄颅骨侧位片以确定蝶窦气化程度,CT 扫描为确定蝶窦气腔的轮廓提供了有价值的资料。局麻后在左侧口角插管,口咽部填塞纱条以防术中血
The authors used the direct transsphenoidal approach for pituitary tumors of the extracranial approach to more than 150 cases of surgery, that the approach fast, safe and effective, less damage to normal tissue. Although the flexibility of the nasal cavity, but to stretch the nose to facilitate the operation of the device is still limited. So often need to be in the nostril and cheek halfway in the nostril, half short outside the nostril incision. Preoperative skull lateral radiographs to determine the degree of sphenoid sinus gasification, CT scan to determine the shape of the sphenoid sinus cavity provides valuable information.
