Description
Summary:Oral cleft surgical repairs are performed using different techniques worldwide. To evaluate and compare the development of the dental arches of children with unilateral cleft lip and palate before and after the primary surgeries performed with different techniques at the first months and six years of life. This is a retrospective longitudinal study. The sample comprised 56 dental casts divided int the following groups: Group 1 (G1) - cheiloplasty (Millard technique) at three months and one-step palatoplasty (von Langenbeck technique) at 12 months; and Group 2 (G2) - cheiloplasty (Millard technique) and two-step palatoplasty: anterior hard palate closure (Hans Pichler technique) at three months and posterior soft palate closure (Sommerlad technique) at 12 months. The digitized dental casts were evaluated at three months - pre-surgical (T1) and six years of life- post-surgical (T2). The following linear measurements were analyzed: intercanine (C-C'), intertuberosity (T-T') distances; anterior dental arch (I-CC'), anterior intersegment (I-C'), and total arch (I-TT') lengths. The palate area was also measured. Parametric and non-parametric tests were applied (p
