Where can I find information regarding effective therapy for hypernasality?
There are many articles and related books and book chapters on the subject of remediating hypernasality. The first step however, is to identify why the hypernasality is occurring. For example, is the hypernasality occurring due to a craniofacial anomaly such as cleft palate or a syndromic condition or another less likely etiology. There may be varied techniques that one can employ to reduce hypernasality in cleft palate versus an unknown etiology. For example prosthetic devices may be useful or surgical intervention in cleft palate where these techniques would be impractical for other types of hypernasality. Once the etiology is identified I would suggest some of the sources indicated below to consult for therapy procedures that may be helpful. If you can give me a more specific diagnosis I can help specify techniques for the particular etiology in question and give a point by point procedure for those therapy applications.
