Transcaruncular anterior ethmoidal artery ligation.

Recurrence of epistaxis after ligation or embolization of the sphenopalatine artery may require ligation of the ipsilateral anterior ethmoidal artery, which cannot be embolized because of the risk to the ophthalmic artery. We describe a transconjunctival transcaruncular approach that allows reliable low-risk access to the anterior ethmoidal artery. This technique offers a minimally invasive approach to the surgical site, without unsightly scar.
