FALLA-ZUNIGA, Luis Felipe  and  ROJAS-CERON, Christian Andrés. Intravenous acyclovir as a treatment for idiopathic peripheral facial palsy in a newborn. Case Report. Iatreia [online]. 2021, vol.34, n.3, pp.275-279.  Epub Aug 04, 2021. ISSN 0121-0793.


Neonatal facial palsy due to Bell’s palsy is rare. A traumatic delivery mechanism represents a common etiology.

Clinical case:

Neonate, without previous illnesses, born by spontaneous non-instrumentalized delivery and without any obstetric complications; who presented acute right facial palsy, with normal brain imaging and clinical findings compatible with Bell’s palsy, who had a good response to antiretroviral management and physical therapy.


Most infants with Bell’s palsy improve with or without treatment, with no serious sequelae. In pediatric population, evidence on benefits of steroids use, alone or with antiretrovirals, has not been conclusive. There is not a current consensus on the safety of late postnatal steroid use, and they should be reserved for neonates who have no other treatment choice. Acyclovir use at 60/mg/Kg/day it’s safe in neonates.


Neonatal Bell’s palsy may present a favorable response to antiretroviral therapy and an adherent physical rehabilitation program, irrespective of steroids use.
