[Endoscopic nasal surgery in treatment of nasopharyngeal angiofibroma].
OBJECTIVE
To avoid complications of the routine surgeries for nasopharyngeal angiofibroma.


METHODS
Endoscopic nasal surgery and other new techniques including controlled-hypotension anesthesia and preoperative feeding artery embolism had been used. From April 1996 to September 1997 eight young male patients with diagnosis of nasopharyngeal angiofibroma were treated by endoscopic sinus surgery. The average age was 16.6 years old. Six accepted preoperative embolism, seven accepted hypotension anesthesia.


RESULTS
No complications had occurred. Average intraoperative blood loss was 900 ml. All cases were followed for 1 to 20 months(mean 8 months). Recurrence was found in only one patient three months after operation. The recurrent rate was 12.5%.


CONCLUSIONS
The lesions limited to nasal and nasopharyngeal cavities and with sphnoid and ethmoid invasions can be removed by endoscopic nasal surgery. Endoscopic surgery has advantages in reducing complications and obtaining better post operative functions. Transnasal endoscopic examination is also necessary in the follow-up period. Other techniques such as CT, digital subtract angiography, preoperative feeding artery embolism and controlled-hypotension technique during anesthesia are beneficial.
