Herpes zoster oticus with delayed facial palsy and multiple cranial nerve involvement

Herpes zoster oticus with multiple cranial nerve (CN) involvement and delayed facial paralysis is a rare occurrence, and there is limited information regarding the disease. We herein report two cases of RHS with delayed facial palsy involving multiple lower CNs. The degree of facial paralysis was not severe as grade III or less, and recovery was observed after treatment. To our knowledge, these are the first cases in the literature to report RHS with delayed facial paralysis and its favorable recovery. It will be a good example for expanding the possibility of treatment in RHS with delayed facial paralysis and multiple CN involvement.
