INTRODUCTION. The evaluation of the size and ossification of the cranial sutures could determine alterations in brain development. The study performed the tomographic evaluation of the size of the previous source and determined the percentage of ossification in the function of age. MATERIALS AND METHODS. A retrospective, observational study was conducted in which 367 cranial CT scans were evaluated in children up to 2 years of age, from January 2012 to August 2015, in four imaging centers in the city of Quito, Ecuador. RESULTS The average size of the previous source in computed tomography with the formula of Popich and Smith was 48,43 mm SD (1515 mm) in men and 37,36 mm SD (13,97 mm) in women, in the group of age from 0 to 3 months, without significant statistical difference (p=> 0.05). 8,0% of patients had a source after 5 months. The average age of the source of the source was 18 months. In the age group from 21 to 24 months, the percentage of ossification was 82,0%. CONCLUSIONS This study provides reference values that detail the percentage of size and the classification of the previous source in the function of age. There is wide variability of the average size of the previous source, which implies premature closure or possible delay as variants of normality.
