目的：探讨两种入路手术治疗垂体腺瘤的优缺点及各自适应怔．方法：经口－鼻－蝶及筛－蝶显微切除垂体腺瘤１０６例．结果：经筛－蝶入路组并发症低、痊愈率高，可能与主要这择的是小腺瘤有关．但其手术路径、手术时间短，出血少，无鼻部并发症。结论：认为两种入路对垂体腺瘤都是理想的手术途径，若肿瘤直径＜２０ｍｍ，更适合经筛－蝶入路。
Objective: To explore the advantages and disadvantages of the two approaches in the treatment of pituitary adenomas and their adaptation. 1. Methods: 106 cases of pituitary adenoma were treated with oral-nasal-sphenoidal and ethmoid-sphenoidal microscopy. RESULTS: The low complication rate and high recovery rate in the Sieve-single approach group may be related to the primary choice of small adenomas. However, the surgical route, short operation time, less bleeding, no nasal complications. Conclusion: It is considered that both approaches are ideal surgical approaches for pituitary adenomas. If the tumor diameter is less than 20 mm, it is more suitable for the ethmoid approach.
