Subacute vestibular neuritides, also known as subacute vestibular neuritis or subacute labyrinthitis, refer to a group of medical conditions characterized by inflammation or infection of the vestibular nerve, which is responsible for transmitting signals from the inner ear to the brain to maintain balance and spatial orientation.
The term "subacute" indicates that the symptoms develop over a period of days or weeks, as opposed to the sudden onset seen in acute vestibular neuritis. Patients with subacute vestibular neuritides often experience vertigo, a debilitating sensation of spinning or whirling, which can be accompanied by nausea, vomiting, and unsteadiness.
During an episode, individuals may have difficulty with coordination, struggle to maintain their balance, and experience visual disturbances such as blurred vision or nystagmus (involuntary eye movements). These symptoms can significantly impact daily activities and quality of life.
The causes of subacute vestibular neuritides can vary. They may result from viral or bacterial infections, autoimmune disorders, or as a consequence of other underlying medical conditions. Treatment typically focuses on alleviating symptoms and addressing the underlying cause when possible. Medications such as antihistamines, antiemetics, and vestibular suppressants may be prescribed to manage vertigo and associated symptoms. In some cases, physical therapy exercises and vestibular rehabilitation techniques may be recommended to help regain balance and reduce dizziness.
Supplementary tests like audiometry and electronystagmography can aid in diagnosing subacute vestibular neuritides by assessing hearing and measuring eye movements, respectively. Overall, managing subacute vestibular neuritides requires a multidisciplinary approach involving otolaryngologists, neurologists, and physical therapists to provide comprehensive care and improve patients' overall functioning and well-being
