A case of massive epistaxis due to internal carotid aneurysm is reported. A 46-yearold female presented with the chief complaint of right epistaxis which had recurred during the past 9 years. The source of bleeding was not determined by routine ENT examination, but the diagnosis of epistaxis due to intracavernous carotid aneurysm was confirmed with the aid of carotid angiograghy. The internal carotid artery was ligatured. Recovery was uneventful, without further epistaxis.<BR>We also performed statistical analysis of clinical feature of 327 out-patients and 39 hospitalized patients with epistaxis. The age distribution of the out-patients was negatively skewed to the under 21 age group. The monthly distribution of out-patients showed an increase in frequency in the winter season in those over 60, and in the spring and summer seasons in those under 10. Hospitalized patients showed increases in January, June, and October. Patients over 30 tended to have systematic diseases and to suffer from severe epistaxis requiring hospitalization.
