YAMASHITA, Renata Paciello et al. Effect of intravelar veloplasty on velopharyngeal closure assessed by pressure-flow technique. Rev. soc. bras. fonoaudiol. [online]. 2010, vol.15, n.3, pp.362-368. ISSN 1982-0232. http://dx.doi.org/10.1590/S1516-80342010000300009.
PURPOSE: To evaluate the effect of intravelar veloplasty on velopharyngeal closure of patients with repaired cleft palate and velopharyngeal insufficiency (VPI), using the pressure-flow technique. METHODS: Forty-seven individuals of both genders, with ages between six and 48 years, with repaired cleft palate±lip and residual VPI, submitted to intravelar veloplasty. The pressure-flow technique was used to measure the velopharyngeal orifice area during the production of the phoneme /p/ in the word "rampa", before and, in average, 12 months after surgery. Velopharyngeal closure was classified as adequate (0 to 0.049 cm2), borderline (0.050 to 0.199 cm2) or inadequate (>0.200 cm2). RESULTS: After surgery, there was considerable improvement in the velopharyngeal closure degree in 66% of the cases. From the patients analyzed, 47% presented adequate closure, 23%, borderline closure and 30% remained with inadequate closure. CONCLUSION: These results showed that intravelar veloplasty led to improvement in velopharyngeal closure in most of the patients studied, consequently decreasing the speech symptoms of VPI.
