Abstract

OBJECTIVES: To analyze the results of surgery for velopharyngeal incompetence (VPI) in velocardiofacial syndrome.

DESIGN: Prospective data collection, with randomized, blind assessment of speech and velopharyngeal function on lateral videofluoroscopy and nasendoscopy.

SETTING: Two-site, tertiary referral cleft unit.

PATIENTS: Forty-two consecutive patients with the 22q11 deletion underwent surgery for symptomatic VPI by a single surgeon.

INTERVENTIONS: Intraoral examinations, lateral videofluoroscopy (+/- nasendoscopy) and intraoperative evaluation of the position of the velar muscles through the operating microscope. Based on these findings, either a radical dissection and retropositioning of the velar muscles (submucous cleft palate [SMCP repair]) or a Hynes pharyngoplasty (posterior pharyngeal wall augmentation pharyngoplasty) was performed. As anticipated, a proportion of patients undergoing SMCP repair subsequently required a Hynes. The aim of this staged approach was to maximize velar function, thereby enabling a less obstructive pharyngoplasty to be performed. Thus, there were three surgical groups for analysis: SMCP alone, Hynes alone, and SMCP+Hynes.

MAIN OUTCOME MEASURES: Blind perceptual rating of resonance and nasal airflow; blind assessment of velopharyngeal function on lateral videofluoroscopy and nasendoscopy; and identification of predictive factors.

RESULTS: Significant improvement in hypernasality in all three groups. The SMCP+Hynes group also showed significant improvement in nasal emission. There were significant improvements in the extended and resting velar lengths following SMCP repair and a trend toward increased velocity of closure.

CONCLUSIONS: Depending on velopharyngeal anatomy and function, there is a role for SMCP repair, Hynes pharyngoplasty, and a staged combination of SMCP+Hynes, all of which are procedures with a low morbidity.
