Dentro de las malformaciones congenitas mas comunes y de mayor prevalencia en nuestro medio y del mundo es el labio y o paladar hendido, y teniendo presente que embriologicamente la formacion de estas estructuras de la cara se desarrollan entre las mismas semanas del desarrollo embriologico de los dermatoglifos , los factores geneticos y ambientales que influyen en la formacion de los labios y paladar , pueden ser reflejados fenotipicamente por los dermatoglifos (Arch, Ulnar Loop, Radial Loop, Whorl).
Los dermatoglifos, siempre han tenido un valor antropologico y policial, actualmente forman parte de una nueva semiologia que se esta construyendo paralelamente a la identificacion de nuevos sindromes y defectos congenitos, de esta manera se haria el examen antes del de los cromosomas, constituyendo un elemento mas de orientacion para decidir si es o no necesario un estudio del cariotipo o bien paralelamente el estudio del cariograma, de esta forma las caracteristicas de las huellas digitales del dedo indice (Arch, Ulnar Loop ,Radial Loop, Whorl) aportarian un valor diagnostico presuntivo que puede disminuir costos en pacientes con labio y/o paladar hendido.
Radial loop, ulnar loop, arches and whorls were recorded (Fig.
In this study, a higher frequency of ulnar loop and arch patterns in male children and a lower frequency of whorls were observed.
Radial loop and ulnar loop were counted, both separately and jointly.
According to the side of opening of the curve loops may be ulnar loop or radial loop (Fig.

Loops are subdivided into two main types--radial loop and ulnar loop according to their positioning and the flow of the ridges.
In the same study on Zimbabweans, ulnar loop were the most predominant digital pattern type in both sexes followed by whorls in males and arches in females.
In Males (Table 1) in both hands combined, whorls, ulnar loops, radial loops and arches are seen in 49.
