PURPOSE: To characterize the velopharyngeal closure pattern in patients submitted to cleft palate surgery and its relation with gender, age, cleft type, and diagnosis of velopharyngeal function. METHODS: Retrospective study based on 89 nasopharyngoscopy studies of operated cleft palate patients with ages between 4 and 47 years (mean=17.32±10.50). Data were analyzed regarding gender, age range (4 to 8, 9 to 12, 13 to 18 and >18 years), cleft type (postforamen or transforamen), diagnosis of velopharyngeal function (adequate, borderline, and inadequate), and velopharyngeal closure patterns (coronal, circular, circular with Passavant's ridge, and sagittal). Results were statistically analyzed. RESULTS: In the study sample, 59.55% of the patients were women; 39.33% were above 18 years of age; 44.94% had post-foramen cleft and 55.06%, transforamen cleft; 14.61% showed adequate, 53.93% borderline, and 31.46% inadequate velopharyngeal closure. With regards to the velopharyngeal closure pattern, 37.08% of the subjects presented coronal closure; 33.71%, circular closure, 15.73% circular with Passavant's ridge; and 13.48%, sagittal closure pattern. There was a relation between pattern of closure and diagnosis of velopharyngeal function (p=0.05). CONCLUSION: Most of the sample presented coronal pattern of velopharyngeal closure, followed by circular, circular with Passavant's ridge and sagittal patterns. There was no relationship between closure pattern and the variables gender, age, and cleft type, but there was a related influence to the diagnosis of velopharyngeal function.
