Sinus Imaging

Abstract

One of the major developments in recent years has been sinus imaging with computed tomography (CT). It is now possible to study the intricate anatomy of paranasal sinuses and, more importantly, their relation to the surrounding vital structures such as skull base, lamina papyracea, internal carotid artery and optic nerve. It delineates key areas such as infundibulum and ostiomeatal complex. CT scanning is now mandatory in the pre-operative evaluation of sinus disease before undertaking functional endoscopic sinus surgery (FESS). The advent of CT scanning has significantly enhanced the scope of endoscopic sinus surgery by offering the surgeon more accurate information regarding sinus status than is possible with plain radiography.
