Comparative quantitative analysis of intravelar veloplasty and Furlow double opposing z plasty techniques for transposition of LVP muscles to correct VPI

Abstract

Purpose The present study was performed to use quantitative analysis of LVP by magnetic resonance imaging (MRI) to compare intravelar veloplasty versus Furlow double opposing z-plasty technique in VPI correction. Materials and methods This is an interventional, comparative study that was carried out on 16 patients with velopharyngeal insufficiency due to decreased velar mobility divided into two equal groups, group I: included eight patients in whom VPI was repaired with intravelar veloplasty, group II: included eight patients in whom VPI was repaired with Furlow double opposing z-plasty. All patients underwent regular follow-up for 3 months by clinical, nasopharyngoscopy and MRI. Results Clinically, there was primary wound healing uneventfully was achieved in all patients in the two groups with no signs of infection. By MRI there was a significant increase in the angle of origin, length and thickness of the LVP postoperatively in both groups with no significant differences between them which confirmed with increased velum mobility postoperatively in both groups in nasopharyngoscopy. Conclusion According to quantitative analysis of LVP by MRI preoperatively and postoperatively, there was no statistically significant differences between intravelar veloplasty and Furlow double opposing z-plasty technique in VPI correction.
