The goal of this prospective randomized clinical trial was to compare 2 cohorts of standardized cleft patients with regard to functional speech outcome and the presence or absence of palatal fistulae. The 2 cohorts are randomized to undergo either a conventional von Langenbeck repair with intravelar velarplasty or the double-opposing Z-plasty Furlow procedure. A prospective 2 × 2 × 2 factorial clinical trial was used in which each subject was randomly assigned to 1 of 8 different groups: 1 of 2 different lip repairs (Spina vs. Millard), 1 of 2 different palatal repair (von Langenbeck vs. Furlow), and 1 of 2 different ages at time of palatal surgery (9-12 months vs. 15-18 months). All surgeries were performed by the same 4 surgeons. A cul-de-sac test of hypernasality and a mirror test of nasal air emission were selected as primary outcome measures for velopharyngeal function. Both a surgeon and speech pathologist examined patients for the presence of palatal fistulae. In this study, the Furlow double-opposing Z-palatoplasty resulted in significantly better velopharyngeal function for speech than the von Langenbeck procedure as determined by the perceptual cul-de-sac test of hypernasality. Fistula occurrence was significantly higher for the Furlow procedure than for the von Langenbeck. Fistulas were more likely to occur in patients with wider clefts and when relaxing incisions were not used.

This retrospective study spans the years 1988 to 2000 and looks specifically at the treatment procedures and outcomes for the correction of velopharyngeal insufficiency (VPI). Ninety-eight patients underwent preoperative assessment by speech pathologists that included perceptual speech evaluation, videofluoroscopy, and, for some, nasendoscopy. Based on this evaluation protocol, a specific surgical procedure was chosen to serve the patients' needs. The four procedures of choice were the palatal pushback with a pharyngeal flap lining, sphincter pharyngoplasty, a superiorly based obturating pharyngeal flap, and Furlow palatoplasty. The criteria for selecting these procedures are reviewed. The results revealed VPI resolution and the establishment of normal nonnasal speech in more than 95% of the 75 patients for whom outcomes were determined. This study reiterates the importance of thorough preoperative evaluation and the individualization of the secondary corrective procedure.
