gonion

 [go´ne-on] (pl. go´nia) (Gr.)
the most inferior, posterior, and lateral point on the angle of the mandible. adj., adj go´nial.

, pl.

go·ni·a

(gō'nē-on, gō'nē-ă), [TA]
The lowest posterior and most outward point of the angle of the mandible. In cephalometrics, it is measured by bisecting the angle formed by the tangents to the lower and the posterior borders of the mandible; when the angles of both sides of the mandible appear on the lateral radiograph, a point midway between the right and left side is used.
[G. gōnia, an angle]

(gō′nē-ŏn′)
n.
The outer point on either side of the lower jaw at which the jawbone angles upward.

[gō′nē·on] pl. gonia
Etymology: Gk, gōnia, angle
an anthropometric landmark located at the most inferior, posterior, and lateral point on the external angle of the mandible, being the apex of the maximum curvature of the mandible, where the ascending ramus becomes the body of the mandible. See also mandible.

Difference in S-Go can be explained with the uncertainty in locating Gonion on digital images as mentioned in the previous investigation about the angular measurements.
The ratios measured as a percentage in this study did not show statistically significant results; however the ratio of posterior facial height to anterior facial height which involved the landmark Gonion (S-Go/N- Me), showed highest standard deviations for any mea- surement recorded, attributable to point Gonion's in- herent poor reliability.
