Epistaxis is one of the most common otorhinolaryngologic emergencies. The majority has mild or moderate level of epistaxis. However, few cases with severely uncontrolled epistaxis is a potentially life-threatening condition for the patient. Management of epistaxis involves an assessment of the bleeding level, haemostasis, considering both local and systemic etiologies and treatment. Traditional methods of haemostasis include one or more of the following: nasal packing, cautery, embolization or ligation of blood vessels. The sphenopalatine artery is a major source of supplying to the nose. Today, with advances in techniques of nasal endoscopy, the popularization of Endoscopic Electrocoagulation of Sphenopalatine Artery (EESA) has been proved by its efficiency and low morbidity. In Vietnam, this method has only been applied in some big hospitals. The aim of this study is to evaluate the role of endoscopic electrocoagulation of sphenopalatine artery for severe epistaxis, thus spreading this technique to other ENT department in Vietnam.
