The use of videonasopharyngoscopy for biofeedback therapy in adults after pharyngeal flap surgery.

Nasopharyngoscopy with videorecording was used as a visual feedback therapy tool to establish and promote consistent closure of the velopharyngeal ports during connected speech after pharyngeal flap surgery. Of the three adults in this report, two achieved consistent closure during connected discourse and have been discharged from therapy; the third demonstrated improved velopharyngeal closure but elected not to continue therapy. These outcomes demonstrate that nasopharyngoscopy biofeedback therapy is useful in helping the motivated adult to achieve better velopharyngeal closure during connected speech after pharyngeal flap surgery or revision. This type of therapy may also prove beneficial with children.
