Arnett's True Vertical Line (TV-line) passing through the subnasale
and perpendicular to the ground, both upper and lower lips must pass ahead of the line.
Material and Methods: A total of 500 (250 male and 250 female subjects) living subjects with both parents of Gujarati descent, aged between 17 and 25 years, were measured for the upper naso-aural distance (n-obs), lower naso-aural distance (n-obi), upper subnasale
aural (sn-obs), lower subnasale
-aural (sn-obi), upper gnathion-aural (gn-obs), and lower gnathion-aural (gn-obi).
The Hyderabad females displayed a decreased ratio over the males, possibly due to the greater distance from nasion to subnasale
A second line was drawn passing through the subnasale
parallel to the interpupillary line.
The G'/Sn-Pg' angle presented greater interobserver error difference in the manual tracing, since the Subnasale
point has a higher average error on the X axis; also, it is hard to locate the Pogonion on a curve, as reported by Chen.
The nasolabial angle was measured as the angle between the line tangent from the Subnasale
(Sn) to the lower border of the nose and the line from the Sn to maxillary lip (Fig) Data had been analyzed using SPSS Version 15.

His cephalometric tracing showed treatment progress (Fig 3) with favorable changes in SNA, ANB, and soft tissue subnasale
and upper lip advancement which reduced his profile concavity at end of week 10 of initiation of treatment.
they are constructed points, so it was not necessary to draw anatomical structures, which are usually operator-dependent, thus allowing bias control during the study; these points were: labrale superius (Ls), labrale inferius (Li), subnasale
(Sn), glabella (G'), columella (Cm), menton (Me), pogonion (Pg'), stomion superius (Stms), stomion inferius (Stmi), and lower vermilion (Vmi).
