We report 2 cases of the same family who presented with alternating re
current episodes of peripheral facial palsy, associated in one case wi
th ipsilateral trigeminal neuropathy and preceded in the other case by
incomplet Miller-Fisher syndrom. All laboratory and radiological inve
stigations were normal except the electrodiagnostic tests. The etiopat
hogenetic mecanisms implied and the distinction between familial recur
rent Bell's palsies and recurrent cranial nerve palsies are discussed.
