Antecedentes: La presencia de dos o mas anomalias craneofaciales puede estar asociada con sindromes y defectos congenitos. La identificacion de anomalias menores y mayores facilita la deteccion temprana, la remision y el diagnostico de malformaciones que se pueden relacionar con condiciones congenitas. Proposito: Disenar, probar y validar un instrumento para detectar clinicamente anomalias menores y mayores que puedan estar asociadas con malformaciones congenitas de la region craneofacial. Metodos: Se realizo un estudio descriptivo piloto en una muestra aleatoria de 34 escolares (21 ninas y 13 ninos), entre 5 y 17 anos de edad. Se tomaron fotografias y medidas antropometricas de variables que se analizaron descriptivamente. Resultados: Un escolar presentaba una malformacion mayor (labio y paladar hendido). Otros hallazgos fueron mesocefalia (47%), macrocefalia (35%), microcefalia (17%), mesoprosopo (8,82%), euriprosopo (5,88%), leptoprosopo (85,29%), anomalias de pelo (67%), asimetrias faciales (76%), frente angosta (44%), depresion metopica (un escolar), anomalias en ojos como pliegues epicantales (26%), anomalias en nariz (11%), anomalias en orejas (64%), apendice preauricular (un escolar), anomalias en boca (35%) y anomalias dentales (58%). Conclusion: El formato se diseno para ser aplicado de forma masiva en las poblaciones y se debe complementar con el estudio del genotipo para corroborar diagnosticos en los casos en que se presentan dos o mas anomalias menores o en los casos con hallazgos relevantes. PALABRAS CLAVE anomalias craneofaciales; antropometria; medidas; sistemico; condiciones; congenito AREAS TEMATICAS diagnostico; anomalias craneofaciales; ortodoncia Background: The presence of two or more craniofacial abnormalities may be associated with developmental syndromes and/or genetic defects. Identifying minor and major anomalies helps early detection, referrals to a specialist, and diagnosis of malformations of congenital origin. Purpose:To design, test, and validate an instrument to detect minor and major clinical craniofacial anomalies that may be associated with congenital conditions. Methods: A descriptive pilot study was carried out with a sample of 34 5-to-17-year-old schoolchildren (21 girls and 13 boys). Photographs and craniofacial anthropometric measurements were taken and variables were analyzed descriptively. Results: Findings showed one schoolchild with major abnormality (cleft lip and palate) macrocephaly (35%), microcephaly (17%), mesoprosopic (8.82%), euryprosopic (5.88%), leptoprosopic (85.29%), hair distribution abnormalities (67%), facial asymmetries (76%), narrow forehead (44%), metopic depression (one child), eye abnormalities such as epicanthal folds (26%), nose abnormalities (11%), ear abnormalities (64%), preauricular appendix (one child), mo and data analysisfrequency anduth abnormalities (35%), and tooth anomalies (58%). Conclusion: The instrument of this study was designed for massive application in communities and should be complemented with genotype analysis in cases with two or more minor abnormalities or other relevant findings.
