Comparing the Unaided Visual Exam to Lateral Cinefluorography in Estimating Several Parameters of Velopharyngeal Function

Abstract

Retrospectively, the medical records of patients with known velopharyngeal insufficiency (VPI) were reviewed for comments based on an unaided visual examination regarding their velopharyngeal function. These comments were compared to objective findings obtained from the cinefluorographic evaluations performed on each of the patients. A total of 68 recorded comments (47 patients) were identified and fell into four broad categories: (1) velar length, (2) depth of the nasopharynx, (3) velopharyngeal closure, and (4) velar mobility. The results revealed an agreement level of 60% between judgments made from visual examinations and cinefluorographic evaluations. This relatively poor agreement suggests that management decisions concerning VPI must include some method of objectively assessing velopharyngeal form and function during connected speech.
