Prolonged Nasal Cul-De-Sac with High Pressure Speech Acts (P.i.N.C.H.), a technique to treat hypernasality, was developed upon the basis of four physiological principles of velopharyngeal function. Preliminary experimental and clinical studies were conducted to determine the efficacy of P.i.N.C.H. in decreasing nasalance in 5 non-cleft palate subjects with velopharyngeal incompetence over a 3-week to 22 month period of time. Results revealed statistically significant decreases in nasalance for posttreatment measures immediately after treatment as well as over several months. It was concluded that P.i.N.C.H. warrants further investigation.
