Nasopharyngeal angiofibroma: (a nine-year experience).

In a nine-year period 50 nasopharyngeal angiofibromas, of whom 13 had recurrent tumour, were treated surgically at the All India Institute of Medical Sciences, New Delhi. A new staging system according to the regions involved was used; 31 patients in whom the tumour was limited to the nasopharynx (Stage I) and those with superior spread into the ethmoid or sphenoid sinuses (Stage IIA) had their tumours removed by a transpalatal route, alone or in combination with other approaches. Tumours with lateral extensions into the pterygopalatine or infratemporal fossae or the cheek (Stage IIB), and those with simultaneous superior and lateral spread (Stage III) underwent a transmaxillary excision (19 cases). In two of the three cases with intracranial extension (Stage IV), the tumour was removed successfully from below. There was no mortality. The usefulness of the transmaxillary approach, especially in recurrent cases, is emphasized. No adjuvant modalities were employed in this series and blood loss was acceptable.
