National long-lasting effect of endonasal endoscopic sphenopalatine artery clipping for epistaxis.

Conclusion: We consider sphenopalatine artery ligation to be a safe and effective treatment of posterior epistaxis as the long-term need for revision surgery and the complication rates are low. Surgery should be considered earlier in the treatment of posterior epistaxis.

Objectives: Posterior epistaxis is common and surgical endoscopic ligation of the sphenopalatine arteries is indicated in severe cases.
