The use of nasopharyngoscopy biofeedback therapy in the correction of inconsistent velopharyngeal closure.

Nasopharyngoscopy was used as a visual feedback tool in a 10-year-old girl who had a repaired bilateral cleft lip and palate and was unable to establish velopharyngeal closure during production of sibilant-fricative sounds. After one session, the patient was able to achieve velopharyngeal closure consistently during speech. Nasopharyngoscopy biofeedback therapy may be a useful tool to help children to achieve consistent velopharyngeal closure during connected discourse.
