Bilateral simultaneous Bell's palsy. Two cases following herpes simplex gingivostomatitis.

Bilateral simultaneous Bell's palsy (BSBP) is an infrequent clinical presentation. Two patients with BSBP following a recent herpes simplex gingivostomatitis are described. From a clinical point of view, these cases support the concept that Bell's palsy may be a partial manifestation of a generalized polyneuropathy, and most probably caused by a reactivated latent herpes simplex virus.
