[Recurrent and alternating peripheral facial palsy in a Rehabilitation department]

Peripheral facial palsy is a relatively frequent condition in rehabilitation departments. The most common aetiology is idiopathic, known as Bell's palsy, which usually has a good prognosis and resolves without sequels. The presence of uncommon symptoms with the facial palsy should lead to suspicion of another possible aetiology, as occurred in the case presented here. Melkersson-Rosenthal's syndrome is one of the entities to keep in mind in the diagnosis of atypical facial palsies. This is an underdiagnosed disease due to the variability of its clinical manifestations. Classically, it manifests as a recurrent and alternating facial edema with peripheral facial palsy and fissured tongue.
