Abstract
In order to improve vocal function, we have two choices to be applied : phonosurgery and voice therapy. For organic voice disorders the first choice should be phonosurgery. On the other hand, if the voice disorders are mainly caused by functional problems such as vocal abuse, hyper-function, hypo-function and so forth, voice therapy must be chosen. In this article, some basic items concerning voice therapy are discussed.
The concept of voice therapy consists of voice training and vocal hygiene. Since there have been many different maneuvers developed for voice therapy, we must be very conscious about selecting the most effective maneuver based on the scientific evidence. In order to choose the most appropriate way, we must consider the status of the function of the vocal organs, such as hyper- or hypo-function, etc.
Vocal hygiene concerns reformation of mal-habits in phonation and improvement of the environment of phonation. When vocal hygiene is introduced to patients, it reduces the recurrence rate of voice quality deterioration and inhibits the occurrence of vocal pathology. Physicians who engage in voice therapy must instruct the patient to observe vocal hygiene.
Voice therapy and vocal hygiene are two essential elements to improve voice problems.
