鼻咽纤维血管瘤理想之手术途径是保证手术野的良好暴露、减少出血、避免功能障碍及并发症。著者的治疗经验如下:(1)明确诊断及了解肿物之准确部位,通过病史询问和物理检查,确定肿物发生于何侧。放射线检查包括造影、平片、颈动脉造影和断层相,颈动脉造影能显示肿物之血液供给及决定结扎何侧颈外动脉;(2)术前服乙烯雌酚,促使肿物变硬缩小,减少术中出血,每日5mg,共30天,有暂时性乳房增大及乳头色素沉着之副作用;(3)在病变侧施行颈外动脉暂时性结扎。采用经腭途径,若肿物侧向伸延,则选用颊腭联合途径,切口处注射含副肾素
An ideal surgical approach for nasopharyngeal fibroangioma is to ensure good exposure of the surgical field, reduce bleeding, avoid dysfunction and complications. The author’s treatment experience is as follows: (1) To confirm the diagnosis and to understand the precise location of the mass, and to determine the mass on which side of the mass occurred through medical history and physical examination. Radiographic examination includes angiography, plain film, carotid angiography, and tomographic imaging. The carotid artery angiography can show the blood supply of the tumor and determine the external carotid artery of the side where it is ligated; (2) Ethenoestradiol is administered before surgery to make the tumor harden and shrink. , reduce intraoperative bleeding, 5mg daily, a total of 30 days, there are temporary breast enlargement and papillary hyperpigmentation side effects; (3) in the lesion side of the external carotid artery temporary ligation. Using the transvaginal route, if the mass is laterally extended, the cheek-spasm approach is used, and the incision site is injected with pararenuin.
