(13) Zy.r-Tr-Zy.l: angle of the face width: formed by the trichion points at the two bilateral zygion points.
Distances of the facial width (zygion to zygion), total face height (trichion to gnathion), short forehead height (trichion to glabella), long forehead height (trichion to nasion), upper face height (trichion to subnasale), morphological face height (nasion to gnathion), nasal bridge length (nasion to pronasale), nose height (nasion to subnasale), and lower face height (subnasale to gnathion) were computed in this study [Figure 1].
Los puntos de referencia craneomaxilares fueron: cristagalli (Cr), nasion (N), espina nasal anterior (ENA), prostion (Pr), y los puntos de referencia derechos e izquierdos del frontozigomatico (Fzd, Fzi), zygion (Zgd, Zgi), mastoideo (Masd, Masi), yugal (Jd, Ji) y ancho nasal (Nasd, Nasi) (figura 2).
Face width was measured as the straight distance between the right and left zygion (zy-zy).
RESULTADOS: El promedio en milimetros del espesor de los tejidos blandos de la cara sobre los puntos craneometricos es el siguiente: Metopion (3.4), Glabela (3.7), Nasion (3.8), rinon (2.7), Midphiltrum (7.7), Prosthium (7.7.), Infradentale (7.4.), Supramental (6.9.), Pogonion (6.3), Gnation (4.4), Eminencia frontal (3.3.), Supraorbital (4.2), Infraorbital (4.4), Maxilar anterior (7.0), Orbital lateral (4.8), Zygion (4.8), Supraglenoidea (6.3), Gonion (6.1), SupraM2 (7.1), Linea oclusal (8.6), las anchuras faciales bicigomatica (139.2), bigoniaca (109.1), y Nasal (38.2) y de las alturas Nasal (49.4), Facial superior (72.7) y Facial total (117.4).
The most commonly defined landmark on the temporal bone is the zygion, also named the lateral or midzygomatic.
Zy = Zygion; Zy/Zy = Bizygomatic arch (AZ); Go = Gonion; Go/Go = Bigonial arch (AG); WD = Width difference = AG--AZ; A = Bizygomatic arch wider than bigonial arch; B = Bigonial arch wider than bizygomatic arch.
Slight asymmetry in two sides was present at the frontal eminence, porion, gonion, zygion, and Whitnall's tubercle (outer canthus), where left measurements were slightly greater than were those of the right.
En cada paciente se identificaron en total 15 puntos cefalo-metricos, 8 de ellos medianos: trichion, supraglabela, glabela, nasion, A' de downs, B' de downs, pogonion y gnathion; y 7 puntos paramedianos: superciliar, supraorbiatrio, infraorbitario, lateral de la orbita (exocanthion), zygion, agujero mentoniano y gonion, los cuales fueron marcados con un lapiz dermografico.
Los resultados muestran diferencias significativas (p >0.05) al comparar los dos grupos etareos, en los puntos B de Downs, gnathion, supraorbitario, infraorbitario, zygion, trichion, A de Downs, pogonion, exocanthion y gonion.
