The analyzed variables were sex, type of cleft lip and affected side of the lip. Cleft types were evaluated according to the Spina classification. All information was stored in a database and subjected to descriptive statistical analysis. Results: Fifty-three percent of the assessed population were male. Among all types of cleft lip and palate, the trans-incisive foramen clefts were the most frequent (72.6%). Regarding the affected side, left clefts were most common (61.3%).
