Answer

Bell palsy recurs in 4-14% of patients, with one source suggesting a recurrence rate of 7%. It may recur on the same or opposite side of the initial palsy. Recurrence usually is associated with a family history of recurrent Bell palsy. Higher recurrence rates among patients were reported in the past; however, many of these patients were found to have an underlying etiology for the recurrence, eliminating the diagnosis of Bell palsy, an idiopathic disease.
