New Therapies to Prevent or Cure Auditory Disorders

This volume focuses on new molecular therapies that aim to prevent specific pathologies of the ear, like age-related hearing loss, noise-induced hearing loss and ototoxicity. The book discusses the regenerative capacity of hair cells in the inner ear

Introduction

Hearing disorders affect more than 15% of people worldwide. One out of three people over 65 years of age has disabling hearing loss, with 80% of young people at significant risk of hearing impairment. The World Health Organization (WHO) ­estimates that by 2050, 10% of the world’s population will have disabling hearing loss. Currently, sensorineural hearing loss (SNHL) is the most common type of hearing disorder, accounting for almost 90% of reported hearing loss. SNHL is characterized by the loss of sensory hair cells in the cochlea and/or neural damage in the auditory pathway. Since hair cells cannot regenerate in the human cochlea, SNHL is permanent. Multifactorial etiologies for SNHL include aging, noisy ­lifestyles and work environments, infections, and more than 300 ototoxic drugs on the market, including the commonly used cancer drug cisplatin. This volume ­provides an up-to-­date resource on the mechanisms underlying hearing disorders, including related pathologies such as tinnitus, a phantom auditor
