Roentgen Diagnosis of Naso‐pharyngeal Masses

Abstract

The roentgen features of nasopharyngeal angio‐fibromas, malignant tumours and antro‐choanal polypi are described. Techniques employed are lateral skiagram of nasopharynx, submentovertical view, Water's projection and contrast naso‐pharyngography. The value of Water's view to show lateral displacement of the coronoid process and the submento‐vertical view to show widening of infratemporal fossa and inferior orbital fissure as signs of extra‐pharyngeal extension of angiofibromas are discussed. A case of cylindroma is reported. Contrast nasopharyngography is advocated in cases with unexplained otologic symptoms and cranial nerve palsies. Contrast nasopharyngography provides a permanent record of tumour regarding size and position before and after treatment. This procedure done post‐operatively documents the extra‐pharyngeal extensions of angiofibromas. Copyright © 1973, Wiley Blackwell. All rights reserved
