青年期鼻咽血管纤维瘤约占所有耳鼻咽喉科肿瘤的0.05%。其组织学虽是良性,但对病人却隐藏着危险,因无法阻止其扩张性生长。如不治疗.可因大出血和侵及颅内重要结构.如视神经和蝶鞍旁区域,而威胁到生命。作者复习文献并报告了1972～1981年手术治疗14例的经验。病人全为男性,年龄10～19岁。按Fisch氏分类:1型:肿瘤限于鼻咽和鼻腔,无骨质破坏;2型:肿瘤扩展至翼腭窝、上颌窦、筛窦、蝶窦;3型:肿瘤侵犯颞下窝、眼眶、鞍
Adolescent nasopharyngeal angiofibroma accounts for about 0.05% of all Otolaryngologic tumors. Although its histology is benign, it is hidden from the patient because it cannot stop its expansionary growth. If not treated, it can be life-threatening due to major bleeding and invasion of important intracranial structures such as the optic nerve and parasellar area. The author reviews the literature and reports on the experience of 14 cases of surgical treatment from 1972 to 1981. The patients were all male and were 10 to 19 years old. According to Fisch’s classification: Type 1: The tumor is confined to the nasopharyngeal and nasal cavity without bone destruction; Type 2: The tumor extends to the pterygopalatine fossa, maxillary sinus, ethmoid sinus, sphenoid sinus; Type 3: The tumor invades the infratemporal fossa, eyelid, saddle
