Fig 1.
Shows step by step representation of the methodology used to measure the angle.
(A) CT scan of the head on coronal cut and (B) axial cut. The black arrow seen pointing at the anterior lacrimal crest on the axial scan with the linked marker seen on coronal cut. (C) and (D) show a diagonal line drawn on the coronal cut, joining the beginning of the anterior lacrimal crest (confirmed by the linked marker on the axial cut) to the end of its curve. (E) Coronal cut of the head showing the horizontal line joining the midpoints of the diagonal lines on either side, with another line going to the most anterior portion of the axilla of the middle turbinate, and the angle present between them (Khedr, Y).
Table 1.
Shows the distribution of patients according to their gender, age and analysis of the angle detected between the medial canthus and middle turbinate.
Fig 2.
Shows a scatter plot graphical representation of all the patients’ angles against the age of the patients.
Fig 3.
Shows a graphical representation of the mean angle in both males and females groups.
Table 2.
Shows the mean, median and range angles for both males and females groups and comparing the results using Independent t-test to show the significance.
Fig 4.
Shows a graphical representation of the mean angle ± standard deviation for each age group.
Table 3.
Shows the stratification of patients into age groups with the mean and range calculated for each age group and the results compared using One Way ANOVA test.
Fig 5.
Shows a 3D reconstruction of a CT scan head in anteroposterior view (left) with the angle between the medial canthus and the middle turbinate measured on it and a coronal cut of the same CT scan head (right) with the angle measured on it (Khedr, Y).
