aetiology
Last reviewed 07/2023
The aetiology of most cases of BPPV is unknown (idiopathic).
Secondary causes of BPPV can be due to various disorders which damage the inner ear
- head trauma
- mastoid surgery
- vestibular neuritis
- labyrinthitis
- Meniere's disease
In contrast to idiopathic BPPV, the traumatic form displays several distinctive characteristics
- higher incidence of bilaterality
- several canals on the same side can be affected
- seen equally among women and men
- more difficult to treat
- recurrence of the disease occurs frequently
In addition, the incidence of BPPV has shown to be higher in patients with migraine. BPPV is also reported to occur with giant-cell arteritis, diabetes, and hyperuricaemia (1).
