Melkersson-Rosenthal syndrome: report of three cases.

Melkersson-Rosenthal syndrome is a rare disorder consisting of the triad of persistent or recurrent orofacial edema, relapsing facial paralysis and fissured tongue. It is far more uncommon to find the complete triad since it generally presents in oligosymptomatic forms. We present three cases of the Melkersson-Rosenthal syndrome with the classic triad of symptoms and discuss the etiology and the clinical and electromyography findings of this syndrome.
