All participants were evaluated for postoperative hypernasality at 2 weeks and monthly up to 3 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Preoperatively, all patients had good intelligibility of speech, 85% of cases had normal resonance, while 15% had a mild degree of hyponasality. Nasofibroscopic examination showed incomplete adenoid closure, adequate palatal length and mobility, and complete velopharyngeal valve closure in all subjects. Regarding velopharyngeal valve closure pattern, 65% of patients exhibited a coronal pattern and 35% a circular pattern. Postoperatively, only 5% of patients developed mild transient hypernasality at the two-week follow-up, while 95% maintained normal resonance. By the one-month assessment, all patients had achieved normal resonance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>There was no significant association between VPV closure patterns and the development of postoperative hypernasality.
