Endoscopic ligation or diathermy of the sphenopalatine artery in persistent epistaxis.

Conventional methods of arterial ligation in persistent epistaxis often involve significant surgical morbidity, as well as failure due to arterial anastomosis. We have performed endoscopic intranasal end ligation or diathermy of 11 sphenopalatine arteries in 10 patients with no complications and with no further episodes of epistaxis, with an average follow-up period of nine months.
