FSTT was recorded at 28 standardised craniofacial points following the Steyn and Cavanagh protocol. Volumetric assessment of the maxillary and frontal sinuses was measured. Discriminant function analysis (DFA) and two artificial neural network (ANN) models were used to classify sex based on the collected data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Both sinus volumes and FSTT showed statistically significant differences between males and females (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.005). DFA achieved an overall accuracy of 80%, correctly identifying 73% of males and 87% of females. Cross-validation resulted in 75.6% accuracy. FSTT varied significantly between sexes at all landmarks.
