Some studies suggest a significant variation in the incidence of primary epistaxis with seasons, while others seems to refute it. Epistaxis being one of the commonest emergencies in ENT warrants research for better prevention and management guidelines. So we conducted a study to know the effect on seasons on the frequency of primary epistaxis cases. The place of study being located at a very high altitude with extremes of cold, dry weather was an ideal natural laboratory for this research. Of the 500 primary epistaxis cases in the study, 187 (37.4%) cases were recorded in winter in contrast to only 73 (14.6%) cases noted in the summer months. January with 77 (15.4%) cases followed by December with 63 (12.6) cases recorded the majority of cases. Our study concludes a definite] significant correlation between frequency of primary epistaxis cases and seasonal variation of temperature and humidity.
