青年期鼻咽血管纤维瘤的手术疗法历来受到广泛推崇,但术后复发率高。关于放疗的价值,各家报道尚不一致。作者报告一男性患者,16岁。因鼻阻塞半年,左眼部及面颊部肿胀6天就诊。检查发现有实性肿物堵塞左侧鼻孔及鼻咽部。X线照片示相应部位有软组织肿块。CT扫描证实肿物已侵犯筛窦并突入颅中窝。活检证实为鼻咽血管纤维瘤。采用4 MeV直线加速器于29天内行15次外照射,总量3000rads。放疗后鼻阻塞及面部水肿消失,但肿物仍存在。放疗后数月,肿物渐趋缩小,9个月后再次CT扫描示鼻咽部肿物明显缩小。1年后患
The surgical treatment of adolescent nasopharyngeal angiofibroma has been widely respected, but the recurrence rate is high after surgery. Regarding the value of radiotherapy, reports are still inconsistent. The author reports a male patient, 16 years old. Due to nasal obstruction for six months, the left eye and cheeks swelled for 6 days. Examination revealed a solid mass blocking the left nostril and nasopharynx. X-ray photographs show soft tissue masses in the corresponding sites. A CT scan confirmed that the tumor had invaded the ethmoid sinus and broke into the middle cranial fossa. Biopsy confirmed nasopharyngeal angiofibroma. Using a 4 MeV linear accelerator, 15 external exposures were performed in 29 days for a total of 3000 rads. Nasal obstruction and facial edema disappeared after radiotherapy, but the tumor was still present. A few months after radiotherapy, the tumor gradually narrowed, and after 9 months the CT scan again showed a significant reduction of the nasopharyngeal mass. 1 year later
