Diagnosis and evaluation

A typical voice evaluation takes approximately one hour. A patient / parental voice questionaire is mailed out prior to a child's appointment, and is very helpful to improve the focus of your child's voice evaluation.

The complete evaluation includes:

• Perceptual analysis: subjective assessment by an experienced pediatric voice clinician
• Acoustic measurements: digital recording of your child's voice to allow for interpretation of fundamental frequency, range, loudness, and other characteristics\
• Electroglottography: a measure of "impedance" across the voice box, reflecting certain characteristics of vocal fold movement
• Complete ear, nose, and throat evaluation
• Videolaryngoscopy with stroboscopic illumination: a view of the larynx and vocal folds, allowing for accurate diagnosis of the nature of the voice disorder
• Videonasopharyngoscopy: an evaluation of palate closure against the posterior pharyngeal wall
