本文分析1962—1972年10月期间所治疗的31例鼻咽部血管纤维瘤,其中1例肿瘤已侵入颅内系用放射治疗。 2.多数肿瘤可伸入邻近部位,特别易伸入蝶窦、筛窦及翼颌间隙(上颌窦后)。这些部位的肿瘤如未发现并切除,为复发的主要原因。 3.治疗成功有赖于术前对这些肿瘤的仔细估计。颈内及颈外动脉选择性造影为术前最重要的诊断方法之一。借可了解肿瘤的大小、扩展情况、血管分布及其主要的营养血管。 4.广泛暴露及彻底手术切除为首选的治疗方法,但肿瘤伸入颅内者除外。手术径路的选择视术前对肿瘤大小、范围的测定及手术者的经验而定。凡肿瘤已侵入颅内者,目前以采用放疗为宜。 5.在过去10年中,这种肿瘤术后复发率已显著减少,此因术前对肿瘤大小、范围更精确的测定及采用广泛暴露、彻底切除的手术原则所致。
This article analyzed 31 cases of nasopharyngeal angiofibromas treated during the period from 1962 to 1972, and one of the tumors had invaded the intracranial system with radiation therapy. 2. Most tumors can extend into adjacent sites, particularly easily into the sphenoid sinus, ethmoid sinus, and pterygopalatine space (post maxillary sinus). Tumors at these sites, if not found and removed, are the main cause of recurrence. 3. Treatment success depends on careful assessment of these tumors before surgery. Selective angiography of the internal and external carotid artery is one of the most important diagnostic methods before surgery. By understanding the size of the tumor, its expansion, its vascular distribution, and its major nutritional blood vessels. 4. Extensive exposure and thorough surgical resection are the preferred treatment methods, with the exception of tumors that protrude into the brain. The choice of surgical route depends on the size and range of the tumor before surgery and the experience of the operator. Where tumors have invaded the brain, it is appropriate to use radiotherapy. 5. In the past 10 years, the recurrence rate of this kind of tumor has been significantly reduced. This is due to the more precise measurement of the size and range of the tumor before surgery and the principle of surgery with extensive exposure and thorough resection.
