Recurrent and residual juvenile angiofibromas

Abstract

In the surgical management of juvenile nasopharyngeal angiofibromas the possibility of recurrences and residual tumours is always there. This study was undertaken to predict the prognostic factors determining recurrence of juvenile nasopharyngeal angiofibroma and to find out the usual sites of these tumours. The medical records of 95 patients with histologically proven juvenile nasopharyngeal angiofibroma were reviewed retrospectively. The commonest surgical approach used was a combined transpalatal and transmaxillary approach with a lazy S incision. A conservative lateral infratemporal approach was used in three cases. Complete removal of the juvenile nasopharyngeal angiofibroma was achieved in 78 (82 per cent) of the cases in a single operation. A residual tumour was found in 17 (18 per cent) cases and recurrences occurred in 13 (13.7 per cent) cases. Extensions into the pterygoid fossa and basisphenoid, erosion of the clivus, intracranial extensions medial to the cavernous sinus, invasion of the sphenoid diploe through a widened pterygoid canal, feeders from the internal carotid artery, a young age and a residual tumour were risk factors found associated with recurrence of juvenile nasopharyngeal angiofibroma.
