目的探讨经额外侧锁孔入路手术切除鞍区颅咽管瘤的应用价值。方法 78例鞍区肿瘤患者,均经额外侧锁孔入路显微手术治疗,分析其临床治疗效果。结果 78例鞍区肿瘤患者中,患有垂体腺瘤实施全切除术治疗者22例,实施次全切除术治疗者6例,2例患者由于肿瘤对颈内动脉产生包绕性且侵入海绵窦实施大部分切除术治疗;28例患者蝶骨平台及鞍结节脑膜瘤实施SimpsonⅠ、Ⅱ级切除治疗;20例颅咽管瘤患者中实施全切除者14例,次全切除者6例,均属于实质性。结论经额外侧锁孔入路能够使得鞍区结构得到充分显现,创伤小、出血少、患者恢复快、美观性高等,值得临床推广。 Objective To investigate the value of surgical resection of craniopharyngioma in the sellar region by additional lateral keyhole approach. Methods Seventy-eight patients with sellar tumor were treated with microsurgical operation by additional lateral locking methods and their clinical effects were analyzed. Results Totally 78 cases of sellar tumors were treated with total resection of pituitary adenoma in 22 cases, subtotal resection was performed in 6 cases, 2 cases of tumors due to the internal carotid artery due to encircled invasive cavernous sinus The majority of resection was performed; 28 cases of spondylolisthesis and saddle nodular meningiomas were treated by Simpson Ⅰ and Ⅱ grade resection; 14 cases of total resection in 20 cases of craniopharyngioma and 6 cases of subtotal resection It is material. Conclusions The extra-side keyhole approach can make the structure of the saddle area fully visible, with less trauma, less bleeding, quicker recovery and higher aesthetic appearance, which is worthy of clinical promotion.
