H80-H83: Diseases of inner ear

The diseases of the inner ear, categorized within the group range of H80-H83 in the ICD-10 WHO 2016 classification, represent a group of conditions that impact the internal part of the ear. These diseases largely affect the cochlea (a spiral-shaped structure essential for hearing) and the vestibular system (which helps in maintaining balance). Common causes of these diseases can be due to infections, genetic disorders, aging, or trauma. Some people with these conditions may experience symptoms like hearing loss, ringing sound in the ear (tinnitus), frequent vertigo (feeling of spinning), and imbalance. The progression of these diseases varies; some conditions are temporary whereas others may lead to permanent damage, often impacting an individual's ability to hear or maintain balance. Inner ear diseases primarily impact the auditory and vestibular systems within the nervous system.
