ENT · Nasal Hemorrhage
The facts most likely to be tested
The most common site for anterior epistaxis is Kiesselbach's plexus, located on the anterior nasal septum.
Posterior epistaxis typically originates from the sphenopalatine artery and is associated with higher risk of airway compromise and significant blood loss.
Initial management for active anterior epistaxis is direct pressure applied to the cartilaginous portion of the nose for at least 10-15 minutes while the patient is leaning forward.
Topical vasoconstrictors such as oxymetazoline or phenylephrine are the first-line pharmacologic adjuncts to achieve hemostasis in anterior bleeding.
Silver nitrate cauterization is the preferred treatment for visible, localized anterior bleeding points after initial pressure and vasoconstriction fail.
Nasal packing is indicated for patients who fail conservative measures, and these patients require prophylactic antibiotics to prevent toxic shock syndrome and sinusitis.
Patients with posterior epistaxis require posterior nasal packing and urgent otolaryngology consultation due to the high risk of complications and systemic comorbidities.
Vignette unlocked
A 68-year-old male with a history of hypertension presents to the emergency department with a persistent, heavy nosebleed that has lasted for 45 minutes. He has attempted to stop the bleeding at home by pinching his nose while tilting his head backward, but the bleeding continues and he reports blood dripping down the back of his throat. On physical examination, he is tachycardic, and active bleeding is visualized from the posterior nasal cavity that does not respond to anterior pressure. His blood pressure is 185/105 mmHg.
What is the most appropriate next step in management?
Posterior nasal packing and otolaryngology consultation
The patient's presentation of blood dripping down the throat and failure of anterior pressure indicates a posterior source, which requires specialized packing and ENT involvement to manage the high-flow bleeding from the sphenopalatine artery.

Etiology / Epidemiology
Most common in children (digital trauma) and elderly (hypertension/anticoagulation). Kiesselbach's plexus is the site of 90% of cases.
Clinical Manifestations
Unilateral or bilateral nasal bleeding. Kiesselbach's plexus is the anterior source; posterior bleeds present with blood in the oropharynx.
Diagnosis
Clinical diagnosis via anterior rhinoscopy. Nasopharyngoscopy is the gold standard for identifying posterior sources.
Treatment
First-line is direct pressure for 10-15 minutes while leaning forward. Use oxymetazoline for vasoconstriction; avoid cocaine in patients with hypertension.
Prognosis
Most resolve spontaneously. Posterior packing requires hospital admission and monitoring for hypoxia.

Epidemiology & Etiology
Bimodal distribution peaks in children and adults aged 50-80. Primary causes include digital trauma, dry air, and anticoagulant therapy. Systemic conditions like hypertension and coagulopathies (e.g., von Willebrand disease) must be considered in recurrent cases.
Pertinent Anatomy
The Kiesselbach's plexus is the convergence of the anterior ethmoidal, sphenopalatine, and superior labial arteries on the anterior septum. Posterior bleeds typically originate from the sphenopalatine artery branch of the internal maxillary artery.
Pathophysiology
Mucosal drying leads to crusting and subsequent vessel rupture. In posterior bleeds, the larger caliber of the sphenopalatine artery results in more significant, difficult-to-control hemorrhage. Chronic inflammation or Osler-Weber-Rendu syndrome (hereditary hemorrhagic telangiectasia) can cause recurrent, high-flow bleeding.
Clinical Manifestations
Anterior bleeds are visible at the nares. Posterior bleeds present with blood in the posterior pharynx despite anterior pressure. Red flags include hemodynamic instability, airway compromise, or signs of hypovolemic shock.
Diagnosis
Diagnosis is primarily clinical. Anterior rhinoscopy with a nasal speculum is the standard initial evaluation. If bleeding persists, nasopharyngoscopy is the gold standard to visualize the posterior nasal cavity and nasopharynx.
Treatment
Initial management requires direct pressure for 15 minutes. If bleeding continues, apply oxymetazoline or phenylephrine-soaked pledgets. Persistent anterior bleeds require silver nitrate cautery or anterior packing. Posterior packing is reserved for refractory cases and requires prophylactic antibiotics to prevent toxic shock syndrome.
Prognosis
Most cases are self-limiting. Patients with posterior packs require pulse oximetry monitoring due to the risk of nasopulmonary reflex causing bradycardia or apnea.
Differential Diagnosis
Trauma: history of nasal fracture
Coagulopathy: history of easy bruising or bleeding
Neoplasm: unilateral obstruction or mass
Foreign body: purulent discharge in children
