Prospective Clinical Study of Bleeding Sites in Idiopathic Adult Posterior Epistaxis

Abstract

OBJECTIVES: The precise identification of the bleeding point is important to the efficient management of epistaxis. Our hypothesis was that the septum was the commonest bleeding site.

STUDY DESIGN AND SETTING: This was a prospective clinical study of 50 consecutive adult idiopathic posterior epistaxis patients carried out in a busy teaching hospital.

METHODS: The nasal cavity was inspected with endoscopy to identify the site of bleeding before any intervention. The location of bleeding sites was recorded on a proforma.

RESULTS: Of bleeding sites posterior to the piriform fossa, 94 percent were identifiable, with 70 percent arising from the septum.

CONCLUSIONS AND SIGNIFICANCE: This is the largest prospective study of the bleeding site in adult patients with posterior epistaxis and the only one with a well-defined population. The vast majority of posterior bleeding sites can be identified by endoscopy without general anesthesia. The septum should be examined closely in cases of idiopathic bleeding.
