AboutA voice disorder is a disturbance of pitch, loudness, or quality of the voice in relation to an individual's age, gender, or cultural background. In the normal production of voice, the airstream is generated by the lungs. As the air passes through the larynx, the vocal folds vibrate, which results in the production of sound. The sound continues to travel through the upper vocal tract and is modified by the resonating characteristics of the pharynx and oral and nasal cavities.
Evaluation servicesVideostroboscopy (LVS)—a technologically advanced system for viewing laryngeal anatomy and physiology, which allows clinicians to view and analyze vocal fold function including:
- irregularity of movement
- inappropriate closure
- degree of hoarseness
