Impact of delayed prosthetic treatment of velopharyngeal insufficiency on quality of life. Indian Journal of Dental Research. 2011 Mar-Apr; 22(2): 356-358.http://imsear.searo.who.int/handle/123456789/140018Palatopharyngeal dysfunction may take place when palatopharyngeal valve is unable to perform its own closing due to a lack of tissue (palatopharyngeal insufficiency) or lack of proper movement (palatopharyngeal incompetence). Palatopharyngeal insufficiency induces nasal regurgitation of liquids, hypernasal speech, nasal escape, disarticulations and impaired speech intelligibility. Prosthetic management of palatopharyngeal insufficiency requires a close co-operation between an otolaryngologist and a speech pathologist. As a result, the patient can be socially and physically rehabilitated with the improved speech quality as well as prevention of leakage of liquids.enFricativeshypernasalityobturatorpalatopharyngeal insufficiencysyllablesArticulation Disorders --etiologyCleft Palate --surgeryHumansMaleOroantral Fistula --rehabilitationPalatal Obturators --psychologyPalate, Soft --pathologyQuality of LifeRespiratory Aspiration --etiologySpeech Disorders --etiologySpeech Intelligibility --physiologyVelopharyngeal Insufficiency --complicationsVelopharyngeal Insufficiency --psychologyVoice Disorders --etiologyYoung AdultArticle
