Imaging Anatomy of the Nasal Cavity and Paranasal Sinuses.

A comprehensive understanding of the anatomic structures of the nasal cavity and paranasal sinuses is paramount for the diagnosis of pathologic processes, the planning of endoscopic surgical procedures, and the implementation of neuronavigation techniques during specific interventions. It is imperative for otolaryngologists, maxillofacial surgeons, and head and neck surgeons to recognize these variations, as certain anatomic variations have been observed to predispose patients to sinonasal pathologies due to obstruction of the drainage pathways. These variations can also affect the rate of complications and the success of endoscopic surgery.
