[Surgical versus non-surgical treatment of posterior epistaxis].

A study was performed in order to compare the efficiency of surgical versus non-surgical treatment in patients hospitalized for epistaxis regarding the source of bleeding, and to identify failure-predicting factors related to specific treatments. 62 patients were included in the study, 36 (58%) of whom suffered from posterior epistaxis and 26 (42%) experienced anterior bleeding. The single factor associated with failure of the non-surgical treatment was the posterior source of the bleeding (p = 0.001). These patients were also hospitalized for a longer period (8, 17 days) than those with anterior epistaxis (4, 62 days) (p = 0.001). The percentage of success for the primary non-surgical treatment in patients with posterior epistaxis was 45% (14/31), significantly smaller (p = 0.0001) than the successful reached in the primary surgical procedure, 87% (13/15); endoscopic cauterization of the sphenopalatine artery. These results support endoscopic cauterization of the sphenopalatine artery as primary care in posterior epistaxis.
