Introduction and objectives.

Peripheral facial paralysis is a condition of the facial nerve that often presents atrial septal pain, vital signs and facial paralysis. In the absence of published studies on the possible etiology of this paralysis, we proposed to carry out a systematic review to find out the serological prevalence of peripheral facial paralysis in the different studies published, including the one carried out at the university of Salamanca in the previous year.

Materials and methods.

Systematic review and meta-analysis of the studies published on the confirmation of peripheral facial paralysis by positive serology.

Results.

A total of 628 patients were analyzed, of which 76 had positive serology (12.10%). The meta-analysis shows heterogeneity among the results and publication bias.

Conclusions.

There is no evidence of a significant relationship between peripheral facial paralysis and recent positive serology, so there would be no benefit from antiviral treatment.
