Fig. 1From: The dimensional and morphological assessment of the frontal sinus in sex estimation among different populationsLateral cephalometric measurements of the frontal sinus. (A) the highest point, (B) the lowest point, (AB) indicates the maximum height of the frontal sinus, (C) anterior point on the wall of the frontal sinus, (D) posterior point of the wall of the frontal sinus, (CD) indicates the maximum width of the frontal sinus. The rate of the height (AB) and width (CD) was calculated as frontal sinus indexBack to article page
