Popis: Introduction: Palatoplasty with elevated bilateral mucoperiosteal flaps using the von Langenbeck technique associated with intravelar veloplasty is a common procedure with low rates of oronasal fistula (ONF) and velopharyngeal insufficiency. The objective is to present the author's surgical experience and the incidence of ONF among 278 patients who underwent primary palatoplasty using the von Langenbeck technique associated with intravelar veloplasty. Methods: This retrospective study analyzed the medical records of 278 patients who underwent primary palatoplasty at the Mário Covas Treatment Center for Craniofacial Malformations of the Guilherme Álvaro Hospital located in the municipality of Santos, São Paulo, Brazil, between May 2010 and May 2018. Results: A total of 278 primary palatoplasty procedures were performed; of them, 225 (80.9%) were performed in two surgical stages and 53 (19.1%) in one surgical stage. The study population included 182 men (65.5%) and 96 women (34.5%). The prevalence of left and bilateral cleft lip and palate was 26.3% and 27%, respectively, and the prevalence of bilateral cleft palate, and right cleft lip and palate was 37.4% and 7.6%, respectively. Sixty-one patients had ONF (21.94%), the incidence of which decreased progressively throughout the study period. Conclusion: Primary palatoplasty, using the von Langenbeck technique associated with intravelar veloplasty, is reproducible when performed in one or two surgical stages, and considered safe when the learning curve is reached with a complication rate similar to those in the literature.
