    Abstract:
    This prospective study was undertaken to assess the long-term stability of velopharyngeal perceptual speech ratings of patients with repaired cleft palate. All patients were evaluated and managed at the Cleft Palate and Craniofacial Deformities Institute, St. Louis Children's Hospital. Patients alternately received palatoplasty with or without intravelar veloplasty. Two senior surgeons standardized their operative procedures and performed or supervised directly all operations. Perceptual speech and language evaluations were conducted by the same experienced speech pathologist when the children were 6 years old and 12 years or older. Data were analyzed from the 28 patients available for long-term follow-up. The intravelar veloplasty (N = 14) and nonintravelar veloplasty (N = 14) groups were similar with respect to cleft anatomy and mean age at palatoplasty and at the second perceptual speech evaluation. Evaluation of the 12-year-old and older ratings indicated that the overwhelming majority of patients improved or maintained clinical stability in perceptual ratings of velopharyngeal function. When assessing direction and magnitude of change (i.e., incremental improvement vs. deterioration), the intravelar veloplasty and nonintravelar veloplasty groups had a similar distribution of perceptual speech ratings at both the 6-year and 12-year or older speech evaluations. Results were consistent with previously published data from our center, that the intravelar veloplasty procedure did not affect demonstrably the incidence of postpalatoplasty auditory perceptual symptoms of velopharyngeal dysfunction.
