The surgeon has to have a plan for reading the CT PNS. Patients undergoing nasal surgery by endoscopic approach are subjected to CT PNS. Patients with nasal symptoms like nasal obstruction discharge from the nose and epistaxis, watering from the eyes undergo imaging of the para nasal sinuses by CT. The points of study of CT PNS are highlighted which are of importance to the surgeon to do safe surgery and prevent complications to the underlying and neighboring important structures. Changes of mucosa, erosion of bony walls and expansion of the sinuses and encroachment into the surrounding areas are noted and are kept in mind while doing surgery to prevent complications and doing safe surgery.
