          Abstract

          RESUMEN Introducción y objetivos. La parálisis facial periférica es una afección del nervio facial que suele cursar con dolor retroauricular, pródromos vitales y parálisis facial. Ante la falta de bibliografía sobre la etiología de dicha parálisis se propuso realizar una revisión sistemática orientada a conocer la prevalencia serológica de la parálisis facial periférica en los diferentes estudios publicados incluyendo el realizado en esta facultad el curso anterior. Materiales y métodos. Revisión sistemática y metanálisis de los estudios publicados sobre la confirmación de una parálisis facial periférica por serología positiva. Resultados. Un total de 628 pacientes fueron analizados, de los cuáles 76 tenían serología positiva (12,10%). El metanálisis muestra heterogeneidad entre los resultados y sesgo de publicación. Conclusiones. No se evidencia que haya una relación significativa entre una parálisis facial periférica y una serología positiva reciente por lo que no se obtendría beneficio con un tratamiento antiviral.

          SUMMARY 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.

          The etiology of Bell’s palsy: a review

          Bell’s palsy is the most common condition involving a rapid and unilateral onset of peripheral paresis/paralysis of the seventh cranial nerve. It affects 11.5–53.3 per 100,000 individuals a year across different populations. Bell’s palsy is a health issue causing concern and has an extremely negative effect on both patients and their families. Therefore, diagnosis and prompt cause determination are key for early treatment. However, the etiology of Bell’s palsy is unclear, and this affects its treatment. Thus, it is critical to determine the causes of Bell’s palsy so that targeted treatment approaches can be developed and employed. This article reviews the literature on the diagnosis of Bell’s palsy and examines possible etiologies of the disorder. It also suggests that the diagnosis of idiopathic facial palsy is based on exclusion and is most often made based on five factors including anatomical structure, viral infection, ischemia, inflammation, and cold stimulation responsivity.

            Bell palsy and herpes simplex virus: identification of viral DNA in endoneurial fluid and muscle.

            To determine whether herpes simplex virus type 1 (HSV-1) causes Bell palsy. Prospective study. University inpatient service. 14 patients with Bell palsy, 9 patients with the Ramsay-Hunt syndrome, and 12 other controls. Viral genomes of HSV-1, varicella-zoster virus, and Epstein-Barr virus were analyzed in clinical samples of facial nerve endoneurial fluid and posterior auricular muscle using polymerase chain reaction (PCR) followed by hybridization with Southern blot analysis. Herpes simplex virus type 1 genomes were detected in 11 of 14 patients (79%) with Bell palsy but not in patients with the Ramsay-Hunt syndrome or in other controls. The nucleotide sequences of the PCR fragments were identical to those of the HSV-1 genome. Herpes simplex virus type 1 is the major etiologic agent in Bell palsy.
