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
