Measurements in a control patient. A reconstruction of the 3DT1 post contrast data from a control patient. The baseline length is 13.9 mm and the perpendicular height is 8.1 mm giving a triangle area of 56.3 mm2. The deflection area on each side averages 10 mm2 (56.3–36.3/2). The average chord length between the vertex and both base attachments is 10.7 mm using Pythagoras’ theorem. Giving an average deflection distance using Eq. (4) of 1.4 mm which is equivalent to the actual deflection in this case. Note, any sinus area below the baseline is ignored in this modelling study.
