Background: Velopharyngeal insufficiency (VPI) expresses the structural and neuromuscular disorder of soft palate pharyngeal walls inhibiting normal functions velopharyngeal (VP) sphincter mechanism. In this study, efficacy dynamic magnetic resonance imaging in diagnosis VPI is investigated. Materials Methods: A total 32 cases, 16 controls cleft palates, were included study. T1 fast spin echo-weighted during rest, investigations with True-fast steady-state precession sequence /sss/ /mmm/ phonations performed. Results: During phonation, complete closure was observed control group, whereas mean VP opening 4.11 cm2 preoperatively 0.21 postoperatively group. postoperative period, only 3 patients did not have closure. second operations, performed 6 months later, muscle repair done. All had Conclusions: cases delayed diagnosis, appropriate application will be sufficient for anatomic without any extra procedures. addition, an objective, noninvasive, reliable, effective modality that may used treatment investigations.
