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.
