OBJECTIVES: This study aimed at evaluating the clinical significance of hematological findings in patients with acute peripheral facial palsy.

MATERIALS and METHODS: For this retrospective case series review, 84 patients who visited our university hospital and were diagnosed with Bell’s palsy (BP) or Ramsay Hunt syndrome (RHS) between March 2017 and March 2019 were enrolled. We documented their epidemiological details, final diagnoses, House-Brackmann (HB) palsy grades, and pretreatment and day 7 post-hospitalization complete blood counts. The outcome was considered favorable if the HB grade at weeks 10–16 was I or II. We analyzed the hematological findings in terms of diagnosis and the final treatment outcomes.

RESULTS: A higher pretreatment neutrophil-to-lymphocyte ratio (NLR) and neutrophil count and a lower day-7 lymphocyte count were observed in patients with RHS with unfavorable outcomes. In such patients, moderate positive correlations were observed between the pretreatment white blood cell, neutrophil, and basophil counts; the NLR and basophil-to-lymphocyte ratio; and the initial HB grade. Only the latter was a significant risk factor for a poor treatment outcome. In patients with BP, both the initial HB grade and the pretreatment eosinophil count were included in a regression model predicting prognosis.

CONCLUSION: Inflammation plays an important role in RHS pathogenesis. Initial RHS severity and the response to corticosteroids may determine the final treatment outcome. However, inflammatory markers do not predict all BP outcomes; BP may be etiologically heterogeneous.
