H81.2
Vestibular neuronitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Vestibular neuronitis, also known as vestibular neuritis, is an inner ear disorder characterized by inflammation of the vestibular nerve. This nerve plays a key role in maintaining balance and spatial orientation. When inflamed, it can cause sudden spells of dizziness or vertigo, often accompanied by balance issues and nausea. Typically affecting adults, vestibular neuronitis can significantly impact daily activities, but with proper diagnosis and management, symptoms often improve over time.
Causes & Symptoms
Clinical Causes: Viral infections, particularly those affecting the inner ear or upper respiratory tract, are the most common triggers. Bacterial infections, though less common, may also lead to inflammation of the vestibular nerve. Immune system responses causing inflammation without infection. Recent illnesses or immune-related conditions that compromise inner ear health.
Key Symptoms: Sudden onset of vertigo (a spinning sensation). Loss of balance or unsteady gait. Nausea and sometimes vomiting accompanying vertigo. Sensitivity to head movements that exacerbate symptoms. Possible feeling of fullness or pressure in the affected ear. No hearing loss typically observed, distinguishing it from other ear conditions like labyrinthitis.
Diagnostic & Treatment
Diagnosis Path: Diagnosis relies on clinical evaluation, including a detailed medical history and physical examination. Healthcare providers may perform tests such as the Dix-Hallpike maneuver or Electronystagmography (ENG) to assess inner ear function. Imaging studies like MRI are rarely necessary but may be used to rule out more serious conditions. The goal is to differentiate vestibular neuronitis from other causes of vertigo, such as Meniere’s disease or stroke.
Treatment Protocols: Treatment strategies focus on relieving symptoms and supporting recovery. Common approaches include:
