Velopharyngeal dysfunction (VPD) refers to excessive nasal resonance or hypernasality during speech as the consequence of anatomical abnormalities of the velopharyngeal sphincter involving the velum (soft palate) and/or pharyngeal walls that compromise the seal between the nasopharynx and oral cavity. Normal phonation requires the generation of a column of air that flows from the subglottis into the upper airway. When (VPD) is present, air escapes through the nose during speech, resulting in the characteristic nasal resonancy. VPD is most commonly associated with cleft palate; it may be the only sign of a submucous cleft palate, or may persist after closure of an overt cleft palate.

Velopharyngeal dysfunction can usually be diagnosed by the speech/language pathologist based on the presence of hypernasal speech, compensatory misarticulations, escape of air through the nose, insufficient oral pressure for consonant production, and aberrant facial movements. Imaging options include fiberoptic nasoendoscopy and videofluoroscopy. Videofluoroscopy is a noninvasive radiologic technique intended to assess the competency of velopharyngeal closure. Videotape recording produces a continuous record of the velopharyngeal mechanism. A barium coating of the pharyngeal structures can be used to provide contrast in the videofluoroscopic image. Frontal and basal viewing angles can be used alone or in combination. The procedure is used to assess various forms of velopharyngeal insufficiency, including cleft palate. Videofluoroscopy is frequently performed as an adjunct to surgical planning in patients who do not respond to conservative treatment such as speech therapy.




Based on a strict evidence-based approach, videofluoroscopic evaluation is considered investigational as a technique to assist in surgical planning for treatment of velopharyngeal insufficiency. For further discussion, see Rationale.

Videofluoroscopic evaluation of velopharyngeal closure may be offered by clinics specializing in treatment of cleft palate or craniofacial abnormalities.




Evaluation of a diagnostic technology typically involves a 3-pronged approach, i.e., determining the technical feasibility of the test, its diagnostic parameters (i.e., sensitivity, specificity, positive and negative predictive value) compared to a gold standard, and whether or not management based on the results of the diagnostic test are associated with an improved health outcome. In the absence of a gold standard, it is particularly important to determine that the diagnostic test ultimately results in an improved health outcome.

Videofluoroscopy of velopharyngeal closure has been performed for many years, and in many articles and textbooks, it is identified as a standard component of surgical planning for velopharyngeal insufficiency. In 1988, an international working group established a system for quantifying, recording, and describing movements of the relevant anatomy. A recommendation was also made that suggested that all patients with velopharyngeal deficiency be studied with both videofluoroscopy and nasopharnygoscopy (1), and the Ad Hoc Committee of the American Cleft Palate-Craniofacial Association suggest videofluoroscopy as one technique that may be helpful in evaluating velopharyngeal insufficiency. (2) For example, it is thought that defining the velopharyngeal closure pattern is particularly important to determine the appropriate surgical intervention. The 3 most common surgical approaches to velopharyngeal dysfunction include pharyngoplasty, pharyngeal flap, or posterior wall augmentation. However, even within these broad categories of surgical approaches, the results of videofluoroscopy have been used to tailor the surgery to the individual patient. (3) Therefore, it is not surprising that a search of the literature did not identify any controlled studies that were specifically designed to investigate the role of videofluoroscopy in surgical planning. In addition, pre- and postsurgery videofluoroscopy would be ideally necessary to compare clinical assessments of speech and anatomic function. Postoperative studies are not routinely performed. In the future, MRI may replace videofluoroscopy. (4,5)
