The aim of this study was to investigate the role of inflammation and atherothrombosis in Bell's palsy (BP) by using neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV), respectively, and to study their relations with the facial nerve enhancement on temporal gadolinium-enhanced magnetic resonance imaging (TGd-MRI). Study Design. Case control study. Setting. Tertiary health institution. Subjects and Methods. This study was performed on 65 patients who were diagnosed with BP and a control group of 35 healthy individuals. The BP patients were also divided into 2 groups, those with facial nerve enhancement on TGd- MRI and those without enhancement. The NLR and MPV of each group were compared. Results. The NLRs of the BP patients were significantly higher than control group (P = .001). The NLRs of patients with facial nerve enhancement on TGd-MRI were significantly higher than patients without enhancement (P = .001). There was a positive and significant correlation between NLR and House-Brackmann (HB) grade of the patients (r = 0.641; P<.05). MPV did not show any significant correlation with any of the parameters studied (P .05). Conclusion. NLR can be used as a new and important marker in BP since it is high in BP patients and significantly correlated with HB grade and facial nerve enhancement on TGd- MR. On the other hand, MPV does not have such correlations. These results offer evidence to support an inflammatory theory rather than microvascular response theory in the etiopatogenesis of BP. © American Academy of Otolaryngology-Head and Neck Surgery Foundation 2014.eninfo:eu-repo/semantics/closedAccessBell's PalsyInflammationInflammatory MarkerMean Platelet VolumeNeutrophil to Lymphocyte RatioArticle152113013510.1177/0194599814555841N/AQ1
