Epidemiology

Labyrinthitis and vestibular neuritis occur in all age groups but are more common in individuals ages 30-60 years.[7][8]​ Viral labyrinthitis typically occurs in adults, whereas purulent bacterial labyrinthitis is more common in children age <2 years who are otitis-prone.

Both conditions account for around 5% of dizziness cases. While females are more likely to be affected by labyrinthitis, both sexes are equally affected by vestibular neuritis.[7][9][10][11]​ The actual incidence and prevalence are not well documented.​

Vestibular neuritis is the third most frequently encountered peripheral vestibular disorder.[12]​ It accounts for up to 9% of visits to outpatient clinics specialized in vertigo treatment and is the sixth most common cause of vertigo/dizziness.​[1][13]​​​​​​[14]​ The annual incidence of vestibular neuritis varies between 3.5 and 15.5 per 100,000 persons.​[11][14][15]​​​​ The highest incidence of vestibular neuritis has been reported in individuals ages 40-50 years.[8]
