Posterior Epistaxis: Identification of Common Bleeding Sites

Abstract

We recommend examination under general anesthesia when conservative measures fail to control bleeding, concentrating on the posterior aspect of the lateral nasal wall. In addition, the lateral aspect of the middle and inferior turbinates may contain a groove within which bleeding points may be concealed. The lateral position of most bleeding sites indicates that use of nasal packing can only attempt to indirectly tamponade blood flow and is rarely justified bilaterally. Electrothermocautery can achieve excellent results with minimal complications. Failure to identify a bleeding point, after thorough examination under general anesthesia, does not require further intervention unless complicated by further bleeding.
