Voice evaluation offers an assessment of the patient’s
techniques and patterns of vocal use. Recording and analysis
includes quantification of the voice signal with respect to
pitch, loudness, quality and variability, as well as measurement
of the acoustic parameters and breathing dynamics. This
technology uses a special light source and magnified lenses to
examine the mucosa of the vocal fold in very high detail. This
allows identification of subtle scarring or vocal fold lesions
that will adversely affect the vibrations created by the vocal
folds and may be causing hoarseness or dysphonia. This measures
the amount and frequency of the flow of gastric contents into
the esophagus and larynx over a 24-hour period. This allows for
the diagnosis of, and proper treatment for, reflux laryngitis.
This measures the quality of the nerve signal reaching the
muscles of the larynx. Using a small needle as an electrode
sensor, the electrical activity of the individual muscles of the
larynx can be sampled, and this provid
