Computerized tomography of paranasal sinuses: A roadmap to endoscopic surgery

Abstract

A detailed knowledge of sinonasal anatomy is a prerequisite for safe and successful surgery. Variation in the key landmarks of sinonasal anatomy was recorded in this study both on radiology and during surgery. These variations are especially important while working near optic nerve because a single wrong step during surgery can lead to visual loss. © Jaypee Brothers Medical Publishers (P) Ltd.
