Transnasal sphenopalatine artery electrocautery for posterior epistaxis.

Abstract

Background: To evaluate the effects of sphenopalatine artery electrocautery for the treatment of recurrent posterior epistaxis.

Methods: Nine patients were enrolled in the study. Seven patients had hypertension, two had diabetes, two received irradiation for nasopharyngeal carcinoma, one had congestive heart failure and one was a heavy drinker. Three patients needed blood transfusion for profound blood loss. The sphenopalatine artery electrocautery was performed transnasally with endoscope. After the sphenopalatine foramen was identified through dissecting the mucosa of middle meatus posteriorly one centimeter from the choana, the neurovascular bundle in the sphenopalatine foramen was cauterized.

Results: Most operations can be performed within fifty minutes with minimal blood loss under local anesthesia. One patient developed minor epistaxis 2 months after surgery, and the bleeding was controlled with medical treatment. The other patients had no recurrent epistaxis after surgery. Thus, epistaxis was well controlled in all patients without complications. The follow-up duration was 2 to 14 months after surgery, with a mean duration of 10 months.

Conclusions: Transnasal sphenopalatine artery electrocautery is a simple, effective and safe method for the treatment of posterior epistaxis.
