Objectives
Narrative objectives1
Age-related vocal cord atrophy is a condition in which the vocal cords atrophy with age, resulting in hoarseness and communication disorders. The aging population in Japan is rapidly progressing, and age-related vocal cord atrophy is a disease that will continue to increase in the future. However, the incidence of age-related vocal fold atrophy in Japan has not yet been established, nor have clear diagnostic criteria or severity classifications been established. Therefore, we aim to clarify the epidemiology of age-related vocal fold atrophy in Japan by conducting a nationwide survey of existing cases of age-related vocal fold atrophy in order to develop diagnostic criteria and severity classifications for age-related vocal fold atrophy cases. Understanding the epidemiology and treatment status of the disease is expected to serve as a foundation for building a database for the search of treatment guidelines.
