Abstract Voice is the element of speech that provides the speaker with the acoustic signal upon which speech massage is carried. Control of voice, is an essential component in the individual’s ability to adjust the social situation, to make good contact and maintain equilibrium in relation to the audience. When the voice deteriorates as a result of strain or actual disease the whole personality suffers with it, giving rise to feeling of in adequacy and insecurity. There are many medical and psychological disorders can affect the vocal quality, one of these disorders is thyroid disease, which can affect the vocal quality by many different ways such as: hormonal changes that occurred in the body due to overacting or underacting thyroid gland, also the change of voice can occurs by compression by the enlarged thyroid gland. These changes which may occur in patients with thyroid disease pre-operatively could be assessed by using Auditory perceptual assessment of voice (A.P.A), and this assessment is of an important value as the patient with thyroid disease may develops some sort of dysphonia after thyroidectomy, which may occur due to injury of recurrent laryngeal nerve during surgery, or due to intubation. So (A.P.A) of patient’s voice will differentiate if the change of voice occurred pre or post-operative, and this detection of the cause of dysphonia will play an important role in solving this problem by treating the cause of dysphonia. |
