N-B measurement describes the position of the apical base of the mandible in relation to
nasion. It is obtained by measuring the distance between point B and
nasion perpendicular (N perpendicular) parallel to the HP.
To locate the new maxilla within the face, tracing is superimposed at
nasion along the facial plane, and the distance between the original and new menton is divided into thirds by drawing two marks (1 and 2).
(2) Nasomental angle: formed by the intersection of a line drawn between the
nasion point (N), the pronasale point, and another line running from the point
nasion (N) to the pogonion point (Pog).
Statistically significant differences were found only for the variable basic upper lip thickness, upper lip thickness, Pog, Rhi, Sn, Labiale inferior, labiomentale in high-angle group; for the variables basic upper lip thickness, upper lip thickness,
nasion, Rhi, Sn, Sto, labiale inferior in low-angle group; for the variables basic upper lip thickness, upper lip thickness, Pog, H angle,
Nasion, Rhi, Sn, Sto, Labiale inferior in normal angle group between the genders.
The total distance between the
nasion and the inion and the total circumference of the head are shown as dashed blue lines

Dobrowolska y colegas [13], en el 2013, observaron en radiografias laterales que el tamano de las vias aereas tiene una estrecha relacion con el angulo ANB (angulo formado por los planos
Nasion, punto A y punto B), lo cual sugiere que patrones esqueleticos clase II tendran vias aereas disminuidas; mientras que patrones esqueleticos clase III tienden a tener vias aereas aumentadas.
(5) The distance between the IOF and the
nasion (Na) (Figure 2).
Midline-frontal (MF) electrode was placed 12 cm above the
nasion, and two earthing electrodes were placed, one on vertex ([C.sub.z]) and another on the left hand.
examined the horizontal position of the eyeball by measuring the distance between the
nasion and the pupil using a digital pupillometer [8].
