经眉锁孔入路显微切除垂体肿瘤

Microsurgery Pituitary Adenoma by Transbrow Keyhole Approach

目的：探讨经眉锁孔入路在切除垂体肼瘤中的临床价值及其治疗体会。方法：2000．2—2005．3期间诊治的垂体肿瘤59例患者均采用经眉锁孔入路手术，经眉锁孔入路：切口完全在眉毛内，长约3cm,在外侧角突钻孔，用铣刀在额部行2．5cm×2cm骨瓣，切除部分眉弓，使骨窗下缘完全位于前颅底眶板上。结果：肿瘤全切38例（65％），次全切18例（30％），大部分切除3例（5％）。结论：此入路对于切除垂体肿瘤，具有微创、暴露充分、全切率高、并发症少的优点。

Objective： To introduce a transbrow keyhole approaeh with microsurgical experience in pituitary adenoma. Methods： Skin incision was made in eye brow. An btial brow- frontal bone flap was made, whose size was 2 .5cm × 2cm. And the inferior margin of bone window entended to the anterial cranial base. Result ： Total removal was achieved in 38 cases （65%）, nearly total reasection in 18 cases, partial resection in 3 cases. Conclusion： The new keyhole approach is good for pituitary adenoma.
