- Abstract: Objective: To compare velopharyngeal (VP) activity of subjects with VP dysfunction (VPD) by acoustic rhinometry, to the activity observed by nasoendoscopy. Methods and Results: This was a prospective clinical study conducted in 25 adults, both genders, with repaired cleft palate, with or without a previously repaired cleft lip, and residual VPD. The outcome measures were nasopharyngeal volume change (∆V) during the Δ production of the velar plosive [k] compared to the rest condition, measured by rhinometry, and VP closure pattern and VP movement, rated by blinded judges by observing nasoendoscopy recordings. A mean ∆V decrease of 15% was observed, which was significantly lower (p<0.05) than the observed in subjects without cleft reference (30%). In 72% of patients reduction was <3cm3, compatible with VPD diagnosis, and in 28%, there was a change ≥3cm3, despite VPD. A circular gap (CI) was observed in 76% of patients and a coronal gap (CO) in 24%. The VP movement was judged to be adequate (A), moderate (M) and inadequate (I) in 64%, 24% and 18%, respectively. ∆V did not differ between CI and CO and between A, M and I. A tendency for a ∆V increase with increasing VP movement was observed. Absolute agreement between the two methods was observed in 56% of patients. Conclusion: Rhinometry was able to identify the impairment of VP activity in most subjects. However, ∆V changes showed no correlation with the pattern and range of VP movement, possibly due to methodological issues. Additional studies are needed to define the rhinometric test's accuracy in identifying VPD.
