    Abstract:
    The purpose of this study was to compare speech and breathing after sphincter pharyngoplasty and the Hogan pharyngeal flap in the management of cleft-related velopharyngeal insufficiency (VPI). We reviewed 78 patients with VPI who had either the Hogan flap (n=30) or sphincter pharyngoplasty (n=48) between 2009 and 2011. Velopharyngeal function, nasal patency, and speech were compared. In the Hogan flap group, 25 patients had achieved velopharyngeal competence and nine had normal speech. In the sphincter pharyngoplasty group, 29 patients achieved velopharyngeal competence and 20 normal speech. The Hogan flap group had a higher rate of velopharyngeal competence (n=25) than the sphincter pharyngoplasty group (p=0.033), but there was no significant difference in intelligibility of speech. Eighteen patients in the Hogan flap group and 33 in the sphincter pharyngoplasty group reported symptoms of snoring, with no significant difference in nasal ventilation. Our results suggest that a posterior pharyngeal flap is a more effective technique for managing VPI after repair of cleft palate than sphincter pharyngoplasty, and causes no more postoperative complications in nasal breathing.
