Overview
There are no echocardiography findings associated with Bell's palsy. Ultrasound of the facial nerve may be used to predict functional outcomes in patients with Bell's palsy. Ultrasound may show increase in facial nerve diameter and side-to-side difference in diameter in patients with facial nerve palsy compared to controls. The diameter of the affected side may be significantly larger than that of the healthy side in patients with Bell's palsy. Ultrasound also may be helpful in the diagnosis of other causes of facial nerve palsy.
