Summary

Background:

Facial nerve palsy is a rare complication of acute otitis media (AOM). The general understanding is that this complication has a bacterial cause although bacteria can be isolated from the middle ear only in approximately two-thirds of cases of AOM. Detection of viral agents from specimens obtained during myringotomy in patients with AOM suggests a possible role of viruses in the etiology of this disease.

Case presentations:

We studied 5 otherwise healthy 17- to 27-month-old children who were referred to the Department of Otorhinolaryngology and Cervicofacial Surgery from December 2012 to January 2016 because of AOM and ipsilateral facial nerve palsy. In all cases, serological tests were indicative of a primary Epstein–Barr virus (EBV) infection and no other causative pathogens were identified during hospitalization. In one patient, the technique of in situ hybridization (ISH) detected EBV-specific ribonucleic acid (RNA) sequences within tissue sections obtained during mastoidectomy.

Conclusions:

The aim of this article is to alert clinicians that AOM induced facial nerve palsy secondary to an acute EBV infection in the pediatric population is very likely more common than originally thought. To our knowledge until the present case series, only 2 cases of AOM induced facial nerve palsy secondary to an acute EBV infection have been reported and no cases of EBV infection proven by the ISH technique showing the presence of EBV-specific RNA sequences in patient’s tissue biopsies have been reported until now.
