Abstract
OBJECTIVE: 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.
