Modified superior pharyngeal flap for the treatment of velopharyngeal insufficiency in children

Objective: To describe a modified rolled superior pharyngeal flap for treatment of velopharyngeal insufficiency (VPI) in children. Methods: Prospective case series at a tertiary care multidisciplinary aerodigestive center. Four children, aged 5-12 years, with VPI refractory to speech therapy resulting after cleft palate (bilateral, submucous, or soft palate only) repair, failed traditional superior pharyngeal flap, fine motor incoordination, or adenoidectomy were studied. All 4 children underwent surgery with a modified superior pharyngeal flap, where aspects of the most commonly employed pharyngeal flap designs were combined to achieve the benefits of each technique and to allow for mucosal covering on either side of the flap, improved control of the lateral port size due to the horizontal-to-horizontal inset technique, and the ability to avoid a vertical or horizontal split in a previously repaired cleft palate. Results: All 4 patients demonstrated resolution of their VPI as measured by subjective and/or objective criteria. Every patient required additional speech therapy postoperatively. Conclusions: Our modified superior pharyngeal flap technique may be a good option in patients with small velopharyngeal gaps undergoing revision velopharyngeal surgery. A larger, longitudinal study would better address the overall outcomes of this technique.
