Abstract
Changes to the velum and velopharyngeal muscles following Furlow double-opposing Z-plasty in a 7-year-old female with submucous cleft palate and velopharyngeal dysfunction (VPD) were evaluated. Perceptual, instrumental (i.e., nasometry and aerodynamic pressure flow), and research MRI analyses were used during pre- and post-surgical time points at a university research clinic. Continuous positive airway pressure (CPAP) therapy was trialed following a failed surgery for residual VPD in the patient. Increases in velar length and thickness, and decreases in levator veli palatini muscle angle of origin and contraction were observed following the Furlow double-opposing Z-plasty surgery. Variable improvements in residual hypernasality following the home-based CPAP therapy protocol were observed.
