Abstract Conclusion: Epistaxis has a bimodal age distribution. Anterior epistaxis of mild severity is more common in children

severe epistaxis occurs more often in adults and elderly patients. The occurrence of spontaneous epistaxis was shown to be weakly-to-moderately and inversely correlated to the mean monthly temperature, relative humidity and total rainfall.Objectives: To describe the clinical and epidemiological profiles of patients diagnosed with spontaneous epistaxis

to correlate its monthly occurrence with meteorological variables.Methods: A retrospective cross-sectional study was performed in a referral ENT service in SAo Paulo, Brazil. The study assessed the clinical and epidemiological features of 508 patients with spontaneous epistaxis treated between February 2010 and January 2011. The occurrence of epistaxis was associated with weather variables for the same study period.Results: Spontaneous epistaxis presented two age peaks of higher incidence (11-20 and 51-70 years). Children more frequently had localized bleeding (p=0.003), in the anterior region of the nasal cavity (p=0.0001), of absent-mild severity (p=0.0082). Diffuse bleeding (p=0.005), of moderate-severe intensity (p=0.003), was more common in adults and elderly patients. The total number of visits because of epistaxis was inversely correlated to mean temperature (R=-0.489

p=0.011), mean relative humidity (R=-0.364

p=0.038), and total rainfall (R=-0.512

p=0.009) during each month of the analyzed period.
