Abstract

Background: Management of the levator veli palatini with intravelar veloplasty has been shown to improve speech resonance. The senior author has introduced a more aggressive procedure where the levator is separately dissected, overlapped, and tightened. This study compares resonance results from four levator management protocols: non-intravelar veloplasty, Kriens intravelar veloplasty, radical intravelar veloplasty, and overlapping intravelar veloplasty. Methods: Retrospective chart review was conducted on 252 patients who underwent primary palatoplasty with speech follow-up at 3 years of age. Velopharyngeal function was evaluated with perceptual speech examinations, and subjects were scored on a four-point scale (0 = normal resonance; 1 = occasional hypernasality/nasal emission/turbulence/grimacing, no further assessment warranted; 2 = mild hypernasality/intermittent nasal turbulence/grimacing, velopharyngeal imaging suggested; and 3 = severe hypernasality, surgical intervention recommended). Fisher's exact test was used to compare outcomes. Results: A single surgeon performed all the non-intravelar veloplasty (n = 92), Kriens intravelar veloplasty (n = 103), and radical intravelar veloplasty (n = 31), whereas the senior author performed the overlapping intravelar veloplasty (n = 26). Cleft severity proportions were equivalent across the four methods (p = 0.28). Patients who underwent overlapping intravelar veloplasty demonstrated significantly better velopharyngeal function, and none required further imaging or secondary surgery compared with the other three procedures (p < 0.001). Conclusions: Speech resonance outcomes at 3 years of age are improved and need for secondary velopharyngeal dysfunction management is reduced with more aggressive levator dissection and reconstruction during primary one-stage palatoplasty. Results were best when the muscle was overlapped.
