Mean occurrence of VP closure was 5% before therapy, 91% after two biofeedback sessions, and 86% in the follow-up after 6 months. Velopharyngeal dysfunction associated with compensatory articulation proved to be equally well trained as VPD on sounds with good articulatory placement. No significant difference was observed in the degree of improvement between phoneme-specific VPD and generalized VPD. The transfer to the level of words and sentences was successful and showed significant stability. The stability of VP closure for vowels was less than the stability for fricatives and stop sounds. Patients gained improved auditory and kinesthetic self-perception of their articulation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Nasopharyngoscopic biofeedback therapy proves to be a quick and effective method to change VPD.
