Radiological study of the nasal septal body

Objectives: The nasal septal body (NSB) is the thickened area of the septum located superior to the inferior turbinates and anterior to the middle turbinates. NSB contributes to nasal breathing via functionally and anatomically. The aim of the present study was to analyze NSB size and its association with such variables as age, septal deviation, and nasal turbinate size Material and Methods This retrospective study included 381 randomly selected patients that underwent paranasal sinus CT between 2014 and 2019. NSB size, septal deviation angle, and middle and inferior turbinate size were analyzed. Results NSB, inferior turbinate, middle turbinate, and inferior turbinate-P were significantly smaller on the deviated side. NSB, inferior turbinate, middle turbinate, and inferior turbinate-P size according to nasal septal angle was also significantly smaller on the deviated side. NSB and inferior turbinate size was positively correlated. Conclusion The NSB is an important structure for the regulation of air flow in the nose and should be evaluated in routine examination of the nose especially before the nasal surgery.
