Exclusively endoscopic removal of juvenile nasopharyngeal angiofibroma: trends and limits.
OBJECTIVE
To determine the feasible conditions for exclusive endoscopic resection of juvenile nasopharyngeal angiofibroma.


METHODS
Retrospective study of 20 patients, with a mean follow-up of 22 months.


METHODS
Six academic referral hospitals.


METHODS
All patients had a preoperative computed tomographic or magnetic resonance imaging scan and at least 1 follow-up computed tomographic and/or magnetic resonance imaging scan 6 or 12 months after surgery. Exclusive endoscopic removal was performed using conventional functional endoscopic sinus surgery instrumentation after preoperative embolization.


RESULTS
Using Radkowski staging, 4, 7, and 9 patients had stage I, II and IIIA tumors, respectively. Seven patients were operated on for a recurrence after open surgery. Extension toward the sphenoid sinus, pterygomaxillary fossa, or infratemporal fossa could be removed. There was no attempt at endoscopic removal of deep skull base or temporal fossa invasion. The mean surgery duration was 135 minutes; mean dimensions of the tumor were 4.5 x 4 x 3 cm; and mean blood loss was 350 mL (median, 300 mL). No recurrences occurred in this series; there were small asymptomatic remnants in 2 cases.


CONCLUSIONS
An exclusively endoscopic management of juvenile nasopharyngeal angiofibroma appears to be effective for small to medium tumors. It should be considered as a first-choice option for these cases (in view of the minimal bleeding, shorter duration, and efficacy).
