Abstract
AIM: The variations and frequency of bony septa in the paranasal sinuses were studied prospectively by means of computed tomography. PATIENTS AND METHODS: The presence and morphology of the septa in the paranasal sinuses were studied in 100 consecutive non-selected adults. RESULTS: 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%). CONCLUSION: 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.
