RESUMO
OBJECTIVES: 1) To compare nasendoscopy (NE) and multiview fluoroscopy (MVF) in assessing velopharyngeal gap size; and 2) to determine the relationship between these assessments and velopharyngeal insufficiency (VPI) severity. STUDY DESIGN AND SETTING: Retrospective review of consecutive patients with VPI at a tertiary care children's hospital, assessed with NE and MVF between 1996 and 2003. RESULTS: 177 subjects. NE and MVF gap areas were correlated (R = 0.34, 95% CI 0.26-0.41). In adjusted analysis, VPI severity was associated with: 1) NE gap area (OR = 2.78, 95% CI 1.96-3.95), 2) MVF gap area (OR 1.64, 95% CI 1.37-1.95), 3) age <5 years (OR 3.30, 95% CI 1.47-7.38), and 4) previously repaired cleft palate (OR 0.48, 95% CI 0.25-0.94). CONCLUSIONS AND SIGNIFICANCE: NE and MVF assessments provide complementary information and are correlated. Both are associated with VPI severity. However, the "bird's-eye view" provided by NE has a stronger correlation with VPI severity than MVF. EBM RATING: B-2b.

BACKGROUND: The objectives of the study were to describe speech outcomes in a large series of patients undergoing Furlow palatoplasty for management of velopharyngeal insufficiency and to test whether preoperative velopharyngeal gap size and other patient characteristics significantly affect those outcomes. METHODS: Data collected included age at the time of surgery, surgeon, type of cleft, syndrome diagnosis, preoperative velopharyngeal gap size as determined by videonasendoscopy, and preoperative and postoperative perceptual speech assessments. Descriptive statistics were generated and ordinal logistic regression on the outcome variable, postoperative velopharyngeal insufficiency severity score, was performed. RESULTS: In this series of 154 patients, 148 had complete perceptual speech data. Of these 148 patients, 72 percent had improvement in velopharyngeal insufficiency severity after the procedure and 56 percent had complete resolution of velopharyngeal insufficiency. Postoperative insufficiency was scored as none or minimal (i.e., resolution) in 38 of 52 patients (73 percent) with a small preoperative velopharyngeal gap, 26 of 51 patients (51 percent) with a moderate preoperative gap, and four of 21 patients (19 percent) with a large preoperative gap. Preoperative velopharyngeal gap size was significantly associated (p < 0.0001) with postoperative insufficiency on ordinal multivariate logistic regression after controlling for preoperative insufficiency and other covariates. There was not a significant association between syndrome diagnosis, age at Furlow palatoplasty (younger than 5 years versus older), gender, surgeon, or presence of submucous cleft palate and postoperative speech outcome, in either the unadjusted or adjusted analyses. CONCLUSIONS: Preoperative velopharyngeal gap size, as determined with nasendoscopy, was significantly associated with postoperative velopharyngeal insufficiency severity after Furlow palatoplasty. Small gap size is associated with a greater likelihood of resolution.
