ABSTRACT

Introduction. Cleft lip alveolus palate (CLAP) is the most frequent congenital malformation of head and neck. The incidence range is one per 700 births. Alterations in development by CLAP cause different changes in the lip, alveolar ridge and palate, affecting soft and hard tissue. Inhibition of growth and development of the facial level in children with FLAP is a well-known and discussed topic. Objective. Identify the factors involved in maxillary growth in patients with unilateral cleft lip alveolus palate in children six to 18 yearsold who were attended on the orthodontic service of the HNP. Materials and methods. It was an observational, descriptive, retrospective study, with a transverse design, with a sample of 92 files, carrying out photographic analysis in an observational radiographic way, Steiner 's analysis, taken the angles SNA, SNB, ANB and t student analysis. The analyzed variables were compared with those of the cephalometric analysis. Results. Prevalence was found larger in male gender, with a mean of eigth years. Observationally, the photographic analysis was performed with relevant results were found in the anterior crossbite (ACB) 94.50 %, labial scar tissue 68.74 %, maxillary collapse 65.20 %. We performed the Steiner analysis, with the t student, SNA-SNB, all analyzed with the radiographic results found that the factors involved in maxillary growth were palatine scar tissue, maxillary collapse and scarring labial tissue. Conclusion. The knowledge of the existence of factors involved in the maxillary growth of patients with CLAP, allow us to avoid the presence of these alterations by means of care protocols.
