Introduction: Bell’s palsy is a common cranial neuropathy causing acute onset of unilateral lower motor neuron type of seventh cranial nerve palsy that result in ipsilateral facial muscle weakness. The aim of this study was to determine the possible correlation of Bell’s palsy and seasonal influence in a district area of Bangladesh.

Results: In our study, out of 214 patients male were 117(54.7%) and female were 97(45.3%). Age range from 4 to 90 yrs, median age was 40.0±17.6 Number of patients with Bell’s palsy presented in various seasons include 44% during winter, 35% during summer, 9% during fall monsoon and 12% during autumn period. We analyzed the data by using Mean±SD and chi-square test. A significant association was evident in winter and summer season (P=0.04 and P=0.045) respectively.
Conclusion: In our present study we found significant relation between seasonal variation and occurrence of Bell’s palsy.
