Presbyphonia is defined as voice change caused by aging. Since presbyphonia is one of the natural aging processes, the treatment should be considered for the patients complaining communication difficulties. The treatment should not only target on presbylaryngis, but also on underlying systemic conditions such as lung function, neurological diseases and medications. Therefore, the treatment for the patients with presbyphonia should be multidisciplinary including underlying disease control, voice therapy and surgical treatment. Although various experiments on treatment of presbylaryngis are currently being tried, repeated injection laryngoplasty is still playing an important role because presbyphonia is destined to get worse over time.

Dysphonia is a medical terminology for voice disorders characterized by hoarseness, harshness, weakness, or even loss of voice ; any impairment in ability to produce voice sounds using the vocal organs, larynx, The causes of dysphonia can be classified into two groups, organic and functional. Functional dysphonia includes spasmodic dysphonia, muscle tension dysphonia, mutational dysphonia and conversion dysphonia, etc, The findings of laryngoscopy in these dysphonia are almost normal. Therefore, physicians should diagnosis these diseases from careful history taking and abundant understandings about the phonation pattern, Organic dysphonia is caused by anatomical problems in the larynx, especially on the vocal fold, Some lesions, however, are not easily found because these lesions are too small, or located on the lower lip of vibrating vocal fold. Laryngopharyngeal reflux induced laryngitis, vascular lesions, sulcus vocalis, vocal atropy including presbylaryngis, and mucosal tears are common lesions easily missed in laryngoscopy, Therefore, a high index of suspicion is necessary to avoid missing vocal fold mucosal lesions, and the strobovideolaryngoscopy is indispensable in making the diagnosis,

The voice of aged persons is known generally to be somewhat different from that of other adults, suggesting that laryngeal change occurs with advancing age. However, because knowledge of the voice characteristics of aged persons is limited, it is difficult to judge whether their voices arc normal. Chart review and laryngoscopic examination from ninety-one patients with hoarseness over the age of 60(1st group) and one hundred sixteen patients with hoarseness below the age of 50(2nd group) were done to define aging related voice disorders. The following results were obtained. 1) Associated diseases related to laryngeal disease were hypertension(12%), pulmonary disease(4.4%), thyroid disease(1.1%) in 1st group and hypertension(9.5%), thyroid disease(1.7%) in 2nd group. 2) The underlying diseases causing hoarseness in order of frequency were benign vocal fold lesion(37.7%), inflammatory disease(36.8%), functional dysphonia(17%) in 1st group and benign vocal fold lesion(43.6%), functional dysphonia(26.3%), inflammatory disease(16.5%) in 2nd group. 3) In stroboscopic findings, atrophy and sulcus of vocal cords are more prevalent in males than in females and edema of vocal cords is more common in females. Generally the voice characteristics of aged persons depend on the mass of the vocal folds which may be decreased through atrophy or be increased by edema. However, other factors such as systemic diseases, drug side effects and compensatory mechanism to presbylaryngis must be taken into account in diagnosing and treating voice disorders in aged persons.

This study evaluated the effect of the therapeutic methods between vocal function exercise(VFE), which has been used for the patients with presbyphonia in the precedent studies and laryngeal calibration technique($SKLCT^{(R)}$), which is designed by the author. We identified 58 patients who was been diagnosed as presbylaryngis by laryngoscopic examinations. 21 patients were underwent voice therapy using $SKLCT^{(R)}$, 20 patients were taken VFE, and the control group of 17 patients were not taken any voice therapy. All subjects received the therapy, ranging from seven to nine sessions, and were evaluated the voice change on pretherapy and posttherapy. The grade of hoarseness, roughness, and breathiness voice were reduced on perceptual judgments after $SKLCT^{(R)}$, but only grade of hoarseness was reduced after the VFE. Jitter, Shimmer, NHR were reduced and MPT were increased after the $SKLCT^{(R)}$(p<.05), while Jitter and SFF were reduced after the VFE. Frequency and intensity range were increased significantly on the posttest performance after taking voice therapy by the $SKLCT^{(R)}$, on the other hand only intensity range was increased after VFE. Especially, we can find the significant change that glottic gap and supraglottic compressions was reduced in most of patients after the $SKLCT^{(R)}$, but there's no changes in the group of VFE and control group. In the study, we can suggest that the $SKLCT^{(R)}$ may be useful in improving the voice qualities and laryngeal function of presbyphonia.
