노년이 되면 후두암이나 신경장애와 같은 질환의 빈도가 증가하는 것이 사실이지만 가장 흔한 음성변화의 원인은 후두의 노화현상에 따른 것이다. 연령과 무관하게 발생하는 성대결절과 같은 질환도 노화의 영향에 따라 그 심각성이 달라지게 된다. 따라서 노인의 음성문제를 다루려면 노화과정에 대한 올바른 이해가 필수적이다. (중략)

Age-related changes in larynx can have a direct impact on voice quality and general comfort level. Observations of vocal aging have spanned perceptual, acoustic, aerodynamic, physical, electromyographic (EMG) and histological levels. Evidence of differential vocal aging in relation to gender and physical condition has been reported. Perceptual, acoustic, aerodynamic, kinematic, EMG and histological data document age-related changes in laryngeal structure and function with advancing age. These changes contribute to a functional age-related impact of vocal hypofunction or compensatory hyperfunction. This review will focus on the current understanding of the clinical and cellular changes in the larynx that lead to presbyphonia.

The presbyphonia is a combination of physiological and structural changes due to aging of the larynx in elderly patients with voice problems. Some of these changes are inevitable, while others may be avoidable or reversible. The fatigue of phonation is the most common clinical symptom of the aging voice. The voice problems with aging are produced from variable causes including the organic lesions of the larynx. It is essential that the curers understand physiologic and pathologic changes of aging voice for minimizing glottal incompetence and improving vocal performance and quality of life of the elderly.

배경 : trill은 혀의 첨부가 호기에 따라 진동하면서 경구개 전방에 부딪혀 나는 소리로 주로 "르" 발음으로 들린다. trill은 성악가들에게는 발성전에 후두의 준비운동으로 사용되고, 성대수술 반흔에 의한 애성환자나 노인성 음성장애환자의 음성치료에도 이용되고 있다. 목적 : trill을 실시할 때 전기성문파 측정법상에서 나타난 성대점막의 움직임을 조사하고 효과적인 trill 기법을 찾아보고자 하였다. (중략)

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.

One week survey to investigate the prevalence rate and clinical characteristics of laryngopharyngeal reflux symptoms in Korea. The subject(n=7,704 patients) was newly enrolled patients at the out patient clinic in 90 ENT departments of resident training hospitals and 11 local clinics, which were voluntarily participated in the study 1) Twenty five percent of all enrolled patients has LPR-related symptoms or clinical findings from the examination by ENT specialists. 2) Among e name of LPR-related diagnosis, globus syndrome was e most common, and follows by reflux laryngitis, and chronic laryngitis. 3) Women was more prevalent than men, and it is common in 5th, 6th, and 7th decades, which seems to be related with aging process. 4) Most popular symtoms of LPR. were globus sensation, conic throat clearing, and hoarseness of unknown origin. 5) Aggravating factors of LPR-related symptoms were tiredness, mental stress, drink alcohol, cigarettes smoking, spicy food, and drinking coffee. 6) LPR-related symptoms were more common in professional voice users. 7) In past medical history, diseases of stomach and tonsillitis were most common.

Aging causes a variety of changes in the structure of the vocal fold (VF), resulting in aging-induced dysphonia (presbyphonia). Several studies have investigated the structure of the VF of elderly people from autopsy as well as animal studies. There is an increasing evidence on correlation of structural changes of VF with deteriorated voice in elderly. Although the cellular mechanisms of aging VF have only partially been elucidated, there are many recent advances in biological treatment on aging VF using bioactive molecules such as growth factors. In this study, I'd like to address aging-related structural, biological, and physiological changes in previous literature about human and rodent aging VFs, to provide further insight into the mechanisms responsible for presbyphonia and to translate the basic researches for future clinical trials.

Background and Objectives : Voice disorder is recognized as a major problem because it negatively affects the elderly's social participation and quality of life. The purpose of this study was to examine the validity and reliability of Korean aging voice index (KAVI), which assesses the quality of life related to the voice of the elderly. Materials and Method : This study was conducted on 211 elderly people aged 65 years or older : 111 patients with voice disorder (mean age 69.8, range 65-80 years) and 100 nomorphonic participants (mean age 70.6, range 65-82 years). Aging voice index was translated into Korean and used and Korean voice-related quality of life (KVQOL) was conducted to verify KAVI. The validity (item validity, concurrent validity, and construct validity) and reliability (test-retest reliability and internal consistency reliability) of KAVI. Results : The item validity (ICC=0.895) and construct validity (r=0.765) showed a high correlation, respectively. And concurrent validity (r=0.748), test-retest reliability (0.851), and internal consistency reliability (${\alpha}=0.832$) were statistically significant in voice disorder group. In addition, there was a significant difference between the voice disorder and the nomorphonic group in AVI total score. Conclusion : KAVI is a validated and reliable quality of life tool that will be useful for assessing the presence and effectiveness of interventions in clinical settings.
