“…Complete velopharyngeal closure during swallowing prevents food and liquid from entering the nasal cavity and allows for a closed system for applying pressure to the bolus [78]. In the participants with PD, pressure in the velopharynx was less than that of age-matched controls.…”

Background Parkinson disease (PD) has detrimental effects on swallowing function. Treatment options are largely behavioral; thus, patients would benefit from an earlier start to therapy. Early swallowing changes in PD are not well-known, so patients do not typically receive swallowing treatment until later in the progression of PD. Objective We used predictive modeling to determine what quantitative swallowing variables best differentiate individuals with early to mid-stage PD from healthy controls. Methods Participants included twenty-six individuals with early to mid-stage PD and 26 healthy, age- and sex-matched controls. Swallowing was evaluated by simultaneous high-resolution manometry and videofluoroscopy as well as the Sydney Swallow Questionnaire (SSQ). Binomial logistic regression was performed on 4 sets of data: 1) high-resolution manometry only; 2) videofluoroscopy only; 3) SSQ only; and 4) all data combined. Results A model from a combined data set had the highest accuracy in differentiating individuals with PD from controls. The model included maximum pressure in the velopharynx (soft palate), pressure variability in the velopharynx, and the SSQ item concerning difficulty with saliva swallowing. No significant models could be generated using the videofluoroscopy data. Conclusions Individuals with PD show quantitative changes in pressure generation and are able to self-assess aspects of swallowing function in the early and mid-stages of PD, even in the absence of swallowing changes seen on videofluoroscopy. A multimodal approach for the assessment of swallowing may be more accurate for determining subtle swallowing changes that occur in the early stages of PD.

A thorough assessment of the velopharyngeal (VP) closure dynamics is important for therapeutic planning in patients with nasal speech. An additional diagnostic tool to the standard endoscopic examination of the VP valve, the "Forced Sucking Test" (FST) is presented. In this study, 110 patients with a normal VP valve and 40 patients with VP insufficiency were subjected to a comprehensive endoscopic examination. When existent, Passavant's ridge clearly appears in 80% of these cases during the FST. This is advantageous, since the ridge is often unseen during routine nasendoscopy. Passavant's ridge appears indistinguishable in shape and level during speech and FST. During FST, the bulge of the uvular ridge is clearly seen on the flat or concave nasal surface of the velum. In cases of diastasis of the velar musculature, the midline V-defect of the velum is clearly seen. The test is particularly important in children with concomitant adenoid hypertrophy. The findings are discussed in terms of their implications for the anatomy and physiology of the VP valve. FST is recommended as an additional and complementary part of the endoscopic examination of the VP valve.
