The variations and frequency of bony septa in the paranasal sinuses were studied prospectively by means of computed tomography.
The presence and morphology of the septa in the paranasal sinuses were studied in 100 consecutive non-selected adults.
CT examinations of 200 maxillary antra showed variations in 26 (13%). There were one complete septum (0.5%), 18 incomplete septa at the base of the antrum (9%) and 7 incomplete septa situated anteriorly (3.5%).
Bony septa in the sinuses may be clinically relevant during sinus endoscopy or tooth implantation. Preoperative examination may reduce the complication rate of these procedures.
