ABSTRACT
OBJECTIVES:
Juvenile nasopharyngeal angiofibroma often recurs if the tumor is large. This report is a long-term follow-up of these cases. It establishes the prognostic values of tumor extensions, analyzes the anatomic factors involved in recurrences, describes the spontaneous evolution of remnants based on a radiographic follow-up, and evaluates the pertinence of complex combined surgical approaches for invasive tumors and the value of complementary endoscopy. STUDYDESIGN:
Retrospective review of 44 cases treated between 1985 and 1996.METHODS:
Statistical analysis of the correlation between recurrence and tumor extension as evaluated by systematic analysis of 18 putative tumor extensions on preoperative computed tomography scans.RESULTS:
Invasion of the skull base affected two-thirds of the patients, and the rate of recurrence was 27.5%. Extensions to the infratemporal fossa, sphenoid sinus, base of pterygoids and clivus, the cavernous sinus (medial), foramen lacerum, and anterior fossa were correlated with more frequent recurrence. Long-term radiographic follow-up revealed putative residual disease in nine asymptomatic patients these remnants gradually involuted.CONCLUSIONS:
The data in the current study emphasize the prognostic value of skull base invasion and the difficulty of complete resection of extended lesions. Tumor remnants detected in symptom-free patients should be kept under surveillance by repeated computed tomography scan, since involution may occur. Recurrent symptoms may be treated by radiotherapy (30 Gy) rather than by extended combined procedures. Endoscopic surgery should be combined with surgery for better control of skull base extensions.
