Integrating perceptual and instrumental procedures in the assessment of velopharyngeal insufficiency.

Although technology for the instrumental assessment of velopharyngeal function has advanced, management decisions still too often depend only on subjective perceptual analyses. Both perceptual and instrumental appraisal are necessary for adequate assessment. Instrumental assessment is essential prior to surgical or other long-term management. The assessment is only as valid as the instruments used. If such instruments are not readily available, clinicians should refer patients to centers where they are available and these examinations are routinely performed.
