Core Tip
Core tip: Currently paranasal sinus computed tomography is routinely used to detect anatomy and pathologies of nasal cavity and paranasal sinuses. Sinonasal region has a great number of variations, and some of them have been determined to be associated with sinonasal mucosal disease. It is necessary to know that some of these variations are associated with protrusion of significant structures such as carotid artery, optic nerve, vidian nerve and maxillary nerve into the sphenoid sinus and care should be observed in surgeries on patients carrying these variations.
