title: Endoscopic endonasal ligation of the sphenopalatine artery.
abstract: Internal maxillary artery ligation for persistent posterior epistaxis is traditionally performed via the transantral approach. Although usually effective in controlling the bleeding it carries significant risks, including damage to the infraorbital nerve, damage to dentition and oro-antral fistula formation. The alternative procedure of endoscopic ligation of the sphenopalatine artery at its exit from the sphenopalatine foramen avoids the morbidity associated with the transantral approach. The technique we describe involves the use of standard FESS instruments and a Ligge Clip applicator. This operation is well within the capability of the Otolaryngologist/Rhinologist experienced in endoscopic sinus surgery.
