  • Descrição: This study aimed to compare the palatal volume in children with unilateral cleft lip and palate before and after two surgical protocols. The sample comprised 120 digitized dental models divided into:Group 1 (G1) children submitted to cheiloplasty at three months (Millard technique) and one-step palatoplasty at 12 months (von Langenbeck technique); Group 2 (G2): children submitted to cheiloplasty (Millard technique) and hard palate closure (Hans Pichler technique) at three months and soft palate closure at 12 months (Sommerlad technique). The dental arches were evaluated at three periods. The volume was measured through stereophotogrammetry system software. Repeated measures ANOVA followed by Tukey test and Friedman test followed by Dunn test was used for intragroup comparisons. Independent t test and Mann-Whitney test evaluated intergroup comparisons. The intragroup analysis revealed that G1 had a statistically significant increase in volume at T2 followed by a reduction at T3 (p=0.003); G2 showed a statistically significant increase of dental arch volume between T1 and T2 (p=0.001). The surgical protocol influenced the palatal volume of children with unilateral cleft lip and palate. This study suggested that two-step palatoplasty was more suitable for dental arch development.
