A Radiological Study of Anatomical Variations of Uncinate Process

Abstract

ABSTRACT Aim (a) To study the variations in the superior attachment of uncinate process. (b) Incidence of pneumatization of uncinate process was also studied. Materials and methods A total 200 sides of 100 CT scans of paranasal sinuses coronal section were studied for variations in the superior insertion of uncinate process using Landsberg and Friedman classification. Incidence of pneumatization of uncinate process was also studied. Results In our study out of 200 sides, type 6 attachment was commonest (41%) followed by types 1 and 2. Pneumatization of the uncinate was seen in very small percentage of cases. Conclusion Lateral insertion of uncinate (lamina papyracea + aggar nassi) is the commonest variant followed by the insertion into the skulbase. Pneumatization of uncinate is rare. Clinical significance Though the inferior attachment of the uncinate is almost constant the superior attachment has several variations, the knowledge of which is very important for the endoscopic surgeon to avoid intraoperative complications.
