Epistaxis

Overview

• Definition: Epistaxis, commonly known as a nosebleed, is the hemorrhage from the nasal cavity. It is generally classified as either anterior or posterior, depending on the origin of the bleeding vessel.
• Epidemiology: Epistaxis is a very common condition, affecting up to 60% of the population at some point in their lives, though only about 10% require medical attention. It has a bimodal age distribution, with peaks in childhood (2-10 years) and adulthood (50-80 years). Incidence tends to be higher during colder months due to dry air and increased upper respiratory infections. Males are slightly more affected than females.
• Classification:
  • Anterior Epistaxis (90-95%): Bleeding originates from vessels on the anterior nasal septum, primarily Kiesselbach's plexus (Little's area), a vascular anastomosis of branches from the anterior ethmoidal, posterior ethmoidal, sphenopalatine, greater palatine, and superior labial arteries. This is typically less severe and easier to control.
  • Posterior Epistaxis (5-10%): Bleeding originates from vessels in the posterior or superior nasal cavity, often from Woodruff's plexus (anastomosis of sphenopalatine and ascending pharyngeal arteries) on the lateral wall, or from branches of the sphenopalatine artery or internal carotid artery system. This is usually more profuse, often flows into the oropharynx, and can be more difficult to control.
  • Primary Epistaxis: Occurs spontaneously without an identifiable underlying cause.
  • Secondary Epistaxis: Associated with a specific local or systemic underlying condition.

Pathophysiology

• Mechanism: The nasal mucosa is highly vascularized, serving to warm and humidify inspired air. Numerous arteries and veins supply the nasal cavity, making it prone to bleeding. Trauma, drying, or inflammation can disrupt the fragile mucosal vessels, leading to hemorrhage.
  • Anterior Bleeds: Usually involve vessels of Kiesselbach's plexus, which is superficial and easily exposed to trauma (e.g., digital trauma, foreign bodies, forceful nose blowing) or mucosal drying.
  • Posterior Bleeds: Typically involve larger, higher-pressure vessels of the sphenopalatine artery system, deeper within the nasal cavity, making them more difficult to access and control.
• Risk Factors:
  • Local Factors:
    • Trauma: Nasal picking (digital trauma), foreign bodies, forceful nose blowing, nasal fractures, facial trauma, barotrauma (diving, flying), vigorous sneezing.
    • Inflammation/Infection: Rhinitis (allergic, non-allergic), sinusitis, upper respiratory tract infections, dry rhinitis, intranasal drug use (e.g., cocaine).
    • Mucosal Drying: Low humidity environments, heaters, air conditioning.
    • Anatomical Defects: Septal deviation, septal perforation.
    • Tumors: Benign (e.g., juvenile nasopharyngeal angiofibroma, inverted papilloma) or malignant (e.g., squamous cell carcinoma).
    • Iatrogenic: Nasal surgery, nasogastric tube placement, nasal steroid sprays (improper technique).
  • Systemic Factors:
    • Hypertension: While not a direct cause, uncontrolled hypertension can increase bleeding duration and severity, especially in posterior epistaxis.
    • Coagulopathies:
      • Inherited: Hemophilia A/B, von Willebrand disease, platelet function disorders.
      • Acquired: Liver disease, renal failure, vitamin K deficiency, disseminated intravascular coagulation (DIC), thrombocytopenia (e.g., ITP, leukemia).
    • Medications: Anticoagulants (warfarin, DOACs like rivaroxaban, apixaban, dabigatran, edoxaban), antiplatelet agents (aspirin, clopidogrel, prasugrel, ticagrelor, NSAIDs).
    • Vascular Abnormalities: Hereditary hemorrhagic telangiectasia (HHT or Osler-Weber-Rendu disease), arterial malformations, aneurysms.
    • Alcohol Use: Impairs platelet function and liver production of clotting factors.
• Protective Factors:
  • Maintaining nasal humidity (e.g., saline sprays, humidifiers).
  • Avoiding digital trauma or aggressive nose blowing.
  • Careful use of nasal steroid sprays (aim away from septum).
  • Good control of systemic conditions (e.g., hypertension).

Clinical Presentation

Signs and Symptoms

• Cardinal Features:
  • Nasal Bleeding: Usually unilateral initially, but can become bilateral if blood flows into the nasopharynx and exits the contralateral nostril or via a septal perforation.
  • Severity: Ranging from a slow ooze or drip to a rapid gush.
  • Location: Anterior bleeds typically present as blood flowing out of the nostril. Posterior bleeds often result in blood dripping into the throat (hematemesis if swallowed and vomited) or expectorated.
• Early Signs: Minor, self-limiting bleeding, often from one nostril.
• Advanced Signs:
  • Profuse, persistent bleeding.
  • Signs of significant blood loss: Lightheadedness, dizziness, pallor, weakness, syncope, tachycardia, hypotension (hypovolemic shock).
  • Frequent swallowing/coughing due to blood draining posteriorly.
  • Blood from both nostrils or bleeding that persists despite initial pressure.
• Atypical Presentations:
  • "Occult" bleeding presenting as unexplained anemia or melena/hematochezia from swallowed blood.
  • Recurrent epistaxis despite apparent control of acute episodes, often indicating an underlying systemic issue or persistent local factor.
  • Bleeding associated with other symptoms like nasal obstruction, facial pain, or vision changes, suggesting a tumor or more extensive pathology.

Physical Examination

• Inspection:
  • Initial Assessment: Assess airway, breathing, circulation (ABCs). Observe for active bleeding from either nostril or into the oropharynx. Estimate blood loss.
  • Nasal Examination (Anterior Rhinoscopy): With good lighting (headlamp/otoscope light), suction, and nasal speculum, identify the bleeding site. Look for Kiesselbach's plexus on the anterior septum. Note septal deviations, perforations, foreign bodies, or masses.
  • Oropharyngeal Examination: Inspect the posterior pharynx for blood drainage, which suggests a posterior bleed or significant anterior bleed that has traversed the nasopharynx.
  • External Nose and Face: Look for signs of trauma, ecchymoses, telangiectasias (e.g., HHT).
• Palpation: Generally not a primary component for diagnosing epistaxis itself, but may be used to assess for facial bone tenderness or instability in trauma cases.
• Special Tests:
  • Nasal Endoscopy (Flexible or Rigid): Essential for visualizing posterior bleeding sites, identifying vascular malformations, polyps, or tumors, especially in recurrent or posterior epistaxis cases. Performed by an otolaryngologist.

Diagnostic Approach

History Taking

• Key Questions:
  • Onset: When did it start? Was it spontaneous or provoked (e.g., trauma, nose picking, blowing)?
  • Duration: How long did it last?
  • Frequency: Is this a first episode or recurrent? How often?
  • Laterality: Which side is bleeding? Initially, one side or both?
  • Amount of Bleeding: Subjective (drip, trickle, gush) and objective (number of tissues soaked, volume estimate, symptoms of blood loss).
  • Attempted Interventions: What was done to stop it? Was it effective?
  • Previous Episodes: History of prior nosebleeds, treatment required.
  • Past Medical History: Hypertension, liver disease, kidney disease, bleeding disorders (personal or family history, e.g., hemophilia, von Willebrand, HHT), vascular malformations.
  • Medications: Current use of antiplatelet agents (aspirin, clopidogrel), anticoagulants (warfarin, DOACs), NSAIDs, topical nasal sprays (steroids, decongestants), herbal supplements (e.g., ginkgo, ginseng, garlic).
  • Social History: Alcohol use, smoking, recreational drug use (especially intranasal cocaine).
  • Occupational/Environmental Factors: Exposure to dry air, dust, chemicals.
  • Associated Symptoms: Nasal obstruction, pain, anosmia, weight loss (suggestive of tumor).
• Red Flags:
  • Massive, uncontrolled hemorrhage.
  • Signs of hypovolemia (tachycardia, hypotension, syncope).
  • Bleeding refractory to conventional packing.
  • Recurrent severe epistaxis without clear cause.
  • New onset, severe epistaxis in an elderly patient, especially on anticoagulation.
  • Evidence of underlying bleeding disorder (petechiae, ecchymoses, prolonged bleeding from other sites).
  • Unilateral epistaxis associated with nasal obstruction, pain, diplopia, proptosis, or other cranial nerve deficits (suggests tumor).
  • History of recent nasal/facial surgery or trauma.

Laboratory Tests

• First-Line: Not routinely required for minor, self-limited anterior epistaxis.
  • Complete Blood Count (CBC): If bleeding is severe, prolonged, recurrent, or if patient shows signs of anemia. Assesses hemoglobin, hematocrit, platelet count.
  • Coagulation Panel (PT/INR, aPTT): Essential for patients on anticoagulants, with known or suspected bleeding disorders, liver disease, or significant/recurrent bleeding.
  • Type and Screen/Crossmatch: If significant blood loss or anticipated need for transfusion.
• Confirmatory:
  • Bleeding Time/Platelet Function Analysis: If platelet dysfunction is suspected despite normal platelet count.
  • Specific Factor Assays (e.g., Factor VIII, Factor IX, vWF antigen, vWF activity): If an inherited coagulopathy (hemophilia, von Willebrand disease) is suspected.
• Monitoring: Repeat CBC for anemia if transfusion given or ongoing significant blood loss.

Imaging

• Recommended: Generally not recommended for acute, uncomplicated epistaxis.
• Advanced: Indicated in specific situations:
  • CT Scan of Paranasal Sinuses and Nasopharynx: For suspected foreign body, chronic sinusitis, nasal polyps, orbital involvement, or suspicion of a mass/tumor (e.g., juvenile nasopharyngeal angiofibroma in adolescent males, other benign/malignant neoplasms). Contrast-enhanced CT may be useful for vascular lesions.
  • CT Angiography (CTA) or Conventional Angiography: For suspected vascular malformations, pseudoaneurysms, or to map vascular supply prior to embolization in refractory posterior epistaxis.
  • MRI: May provide better soft tissue delineation than CT for certain tumors.

Management

Acute Management

• Immediate:
  1. Patient Positioning: Sit upright, lean forward to prevent blood from flowing into the pharynx and being swallowed (can cause nausea/vomiting or aspiration).
  2. Direct Pressure: Pinch the soft, cartilaginous part of the nose (just below the bony bridge) firmly and continuously for 10-15 minutes by the clock. Breathe through the mouth. Avoid checking every minute.
  3. Topical Vasoconstrictors: While applying pressure, topical nasal decongestants like oxymetazoline (Afrin®), phenylephrine, or epinephrine (1:10,000 solution on cotton pledgets) can be sprayed into the nostril to aid vasoconstriction.
• Stabilization:
  • ABCs: For severe bleeding, assess airway, breathing, and circulation. Secure airway if necessary.
  • IV Access: Establish large-bore IV access if signs of hypovolemia or anticipated severe blood loss.
  • Fluid Resuscitation: Administer IV fluids (normal saline, lactated Ringer's) for hypovolemia.
  • Reverse Anticoagulation/Coagulopathy: If severe bleeding and patient is on anticoagulants/antiplatelets, consider reversal in consultation with prescribing physician and hematology:
    • Warfarin: Vitamin K (oral/IV), Prothrombin Complex Concentrate (PCC), or Fresh Frozen Plasma (FFP).
    • DOACs: Specific reversal agents (e.g., idarucizumab for dabigatran, andexanet alfa for rivaroxaban/apixaban), or PCC.
    • Antiplatelets: Platelet transfusions (consider for severe thrombocytopenia or antiplatelet-induced bleeding if life-threatening and other measures fail).
    • Desmopressin (DDAVP): May be considered for uremic platelet dysfunction or mild von Willebrand disease.
• Emergency (If initial measures fail or severe bleeding):
  1. Anterior Bleeds (If direct pressure fails):
     • Cautery:
       • Chemical Cautery: Silver nitrate sticks are applied to the visualized bleeding point for 5-10 seconds. Avoid cauterizing both sides of the septum at the same time to prevent septal perforation. Anesthetize mucosa with topical lidocaine/oxymetazoline prior.
       • Electrocautery: Bipolar cautery is highly effective for discrete bleeding points. Requires specialized equipment and training.
     • Anterior Nasal Packing:
       • Non-absorbable: Petroleum gauze (½ inch wide) layered in accordion fashion, anterior nasal balloon catheters (e.g., Rapid Rhino, Merocel). Provide firm, continuous pressure. Left in place for 24-72 hours. Prophylactic antibiotics (e.g., amoxicillin/clavulanate or cephalexin) often given to prevent rhinosinusitis and toxic shock syndrome.
       • Absorbable: Oxidized cellulose (Surgicel), gelatin sponge (Gelfoam), or topical thrombin. Useful for minor oozing, especially in coagulopathic patients.
  2. Posterior Bleeds (Suspected if anterior packing fails, or blood seen actively draining into oropharynx despite anterior pack):
     • Posterior Nasal Packing: More complex, painful, and requires admission.
       • Balloon Catheters: Commercial posterior nasal balloons (e.g., Rapid Rhino posterior, Epistat). Inflate anterior and posterior balloons as per instructions.
       • Foley Catheter: A #10-14 French Foley catheter can be passed through the bleeding nostril, inflated in the nasopharynx, and pulled forward to tamponade the posterior choana, then anterior pack placed.
       • Gauze Pack: Traditional method using gauze rolled and tied, advanced into nasopharynx, then pulled forward. Requires experienced personnel.
     • Surgical Consultation: Early consultation with otolaryngology for refractory posterior epistaxis.
       • Surgical Ligation: Endoscopic sphenopalatine artery ligation is the most common surgical treatment for refractory posterior epistaxis. Anterior ethmoidal artery ligation (external approach) may be necessary for bleeding from the superior part of the nasal cavity.
       • Endovascular Embolization: Angiographic embolization of the internal maxillary artery branches (which supply the sphenopalatine artery) or external carotid artery branches can be performed by interventional radiologists for severe, persistent posterior epistaxis, especially in high-risk surgical patients or for vascular malformations.

Chronic Management

• Pharmacological:
  • Topical Emollients: Petroleum jelly, saline gels (e.g., Nasal Gel), or bacitracin ointment applied to the anterior nasal septum twice daily to moisturize mucosa and prevent crusting.
  • Nasal Saline Sprays/Rinses: Regular use to keep nasal passages moist.
  • Topical Tranexamic Acid (TXA): Can be applied to a cotton pledget or sprayed. Evidence suggests benefit for reducing recurrence in some patients. Systemic TXA (oral or IV) may be considered for patients with coagulopathies or HHT.
  • Bevacizumab (Avastin): Systemic or topical for HHT-related epistaxis, targets VEGF to reduce telangiectasia bleeding.
  • Adjusting Medications: Collaborate with cardiologists/hematologists to reassess need for antiplatelet/anticoagulant therapy if epistaxis is frequent and severe. Never unilaterally discontinue these agents without expert consultation.
• Non-pharmacological:
  • Humidification: Use cool-mist humidifiers, especially in bedrooms during dry seasons.
  • Avoid Digital Trauma: Education on proper nose blowing technique (gently, one nostril at a time) and avoiding nose picking.
  • Avoid Irritants: Smoking cessation, avoid exposure to harsh chemicals.
  • Manage Underlying Conditions: Optimal control of hypertension, allergic rhinitis, or other systemic diseases.
• Monitoring:
  • Regular follow-up after acute episodes to ensure healing and identify recurrence.
  • Review medication adherence and any changes to risk factors.
  • For patients with chronic recurrent epistaxis, consider regular endoscopic evaluations.

Treatment Algorithms

• First-Line:
  1. Self-Care/Immediate (Patient or first responder): Lean forward, pinch soft part of nose for 10-15 minutes. Consider topical vasoconstrictor.
  2. Medical Evaluation (If severe or persistent): Identify bleeding site via anterior rhinoscopy.
  3. Targeted Treatment:
     • Anterior Bleed, Mild/Moderate: Chemical cautery (silver nitrate) if a discrete vessel is seen.
     • Anterior Bleed, Moderate/Severe or Cautery Failure: Anterior nasal packing (absorbable or non-absorbable).
• Second-Line:
  1. Suspected Posterior Bleed or Anterior Packing Failure: Posterior nasal packing (balloon catheters, Foley catheter).
  2. Refractory to Packing: Consult Otolaryngology for surgical intervention.
• Refractory Cases:
  1. Endoscopic Sphenopalatine Artery Ligation (ESPAL): Gold standard for persistent posterior epistaxis.
  2. External Ethmoidal Artery Ligation: For bleeding from superior nasal cavity.
  3. Endovascular Embolization: For severe, diffuse, or anatomically challenging posterior bleeds, or in high-risk surgical patients.
  4. Septal Dermoplasty: Surgical procedure (removing affected mucosa and skin grafting) for severe, recurrent HHT-related epistaxis.
  5. Laser Photocoagulation: For diffuse telangiectasias in HHT.

Complications

• Common:
  • Recurrence: Especially if underlying cause is not addressed.
  • Discomfort/Pain: From packing, cautery.
  • Nasal Obstruction: From packing or crusting.
  • Septal Perforation: From aggressive cautery (bilateral), prolonged packing pressure, or trauma.
  • Synechiae (Adhesions): Between septum and lateral nasal wall.
  • Nasal Vestibulitis: Infection of nasal entrance.
  • Sinusitis: From obstruction of sinus drainage by packing.
• Serious:
  • Hypovolemic Shock: From massive blood loss.
  • Airway Compromise: Especially with posterior packing (pack displacement, difficulty breathing through mouth).
  • Aspiration: Of blood, especially if patient is supine or has altered mental status.
  • Toxic Shock Syndrome (TSS): Rare but life-threatening complication associated with prolonged nasal packing (especially non-absorbable). Prevention includes prophylactic antibiotics and limiting packing duration to 24-72 hours.
  • Vision Loss: Extremely rare, potential complication of ethmoidal artery ligation or orbital hematoma from trauma.
  • Stroke/Transient Ischemic Attack (TIA): Rare complication of endovascular embolization.
  • Infection: Local (e.g., cellulitis, abscess), or systemic.
• Long-term:
  • Chronic nasal obstruction or dryness.
  • Anosmia (rare).
  • Psychological distress from recurrent bleeding.

Prognosis

• Factors:
  • Etiology: Simple anterior bleeds have an excellent prognosis. Bleeding due to systemic coagulopathies, HHT, or tumors may be more challenging to control and have a less favorable prognosis for complete resolution without addressing the underlying cause.
  • Severity: Initial severity and amount of blood loss.
  • Age: Elderly patients tend to have more severe and difficult-to-control epistaxis due to comorbidities, friable vessels, and medication use.
  • Comorbidities: Presence of hypertension, liver/kidney disease, bleeding disorders, or cardiovascular disease.
  • Adherence to Treatment/Preventive Measures: Patient compliance with instructions for nasal care, medication adjustments, and follow-up.
• Survival: Generally excellent for most epistaxis cases. Mortality directly attributable to epistaxis is extremely rare, usually only occurring in cases of massive hemorrhage leading to unresuscitatable hypovolemic shock, or severe complications from intervention.
• Quality of Life: Recurrent, uncontrolled epistaxis can significantly impair quality of life due to anxiety, social embarrassment, work/school disruption, and the discomfort of interventions. Successful management greatly improves QoL.

Prevention

• Primary: Preventing initial occurrence.
  • Nasal Humidification: Use cool-mist humidifiers, especially in dry climates or during winter months.
  • Topical Emollients: Apply petroleum jelly or saline-based nasal gels to the anterior nasal septum twice daily.
  • Avoid Digital Trauma: Educate patients, especially children, about refraining from nose picking. Trim fingernails.
  • Proper Nose Blowing: Advise gentle blowing, one nostril at a time.
  • Careful Nasal Spray Use: Direct nasal steroid sprays away from the septum.
  • Smoking Cessation: Avoidance of nasal irritants.
• Secondary: Early detection and intervention to prevent severe episodes.
  • Identify and Manage Risk Factors:
    • Optimize control of hypertension.
    • Review and, if possible, adjust antiplatelet/anticoagulant medications in consultation with the prescribing physician.
    • Treat allergic rhinitis or chronic sinusitis.
    • Screen for and manage inherited bleeding disorders.
  • Patient Education: Teach patients initial self-management techniques (direct pressure, topical vasoconstrictors) and when to seek medical attention.
• Tertiary: Preventing complications and recurrence after an episode.
  • Post-Treatment Care: Instructions on avoiding strenuous activity, hot showers, bending, heavy lifting for several days post-bleed.
  • Follow-up: Ensure pack removal, assess healing, and reinforce preventive measures.
  • Treat Underlying Causes: Comprehensive work-up and management of any identified systemic or local pathology.

Special Populations

• Pediatric:
  • Most common type is anterior, often due to digital trauma (nose picking) or mucosal drying.
  • Foreign bodies are a common cause; always consider in unilateral, foul-smelling discharge with bleeding.
  • Consider coagulopathies, especially if recurrent or severe.
  • Juvenile nasopharyngeal angiofibroma (JNA) should be suspected in adolescent males with recurrent, severe epistaxis and nasal obstruction.
  • Management often starts with conservative measures, emollients, and cautery. Packing is less common and usually shorter duration.
• Geriatric:
  • More common, often more severe, and frequently posterior.
  • Higher prevalence of comorbidities (hypertension, atherosclerosis).
  • More likely to be on antiplatelet or anticoagulant medications.
  • Nasal mucosa is often atrophic and less resilient.
  • Higher risk of complications from packing (TSS, airway compromise) and interventions. Careful monitoring is crucial.
• Pregnancy:
  • Increased incidence due to hormonal changes leading to increased vascularity and mucosal congestion.
  • Usually anterior and self-limiting.
  • Avoidance of certain vasoconstrictors (e.g., high-dose systemic pseudoephedrine) is often advised, though topical oxymetazoline is generally considered safe for short-term use.
  • Management is generally conservative, similar to non-pregnant adults.
• Comorbidities:
  • Anticoagulation/Antiplatelet Use: Do not stop these medications without consulting the prescribing physician. Risk-benefit of reversal must be carefully weighed against thrombotic risk. Local control is always the first step.
  • Hypertension: Acute elevation of blood pressure can exacerbate bleeding, but rarely causes it directly. Control blood pressure, but focus on stopping the bleed first. Aggressive lowering of BP is not usually required unless hypertensive emergency is present.
  • Hereditary Hemorrhagic Telangiectasia (HHT): Diffuse telangiectasias throughout the nasal mucosa lead to frequent, severe bleeding. Standard cautery is often ineffective and can worsen the condition. Specific treatments include septal dermoplasty, laser photocoagulation, estrogen therapy, and bevacizumab.
  • Liver Disease/Renal Failure: These conditions often cause coagulopathy. Management requires addressing the underlying condition and potentially platelet transfusion or fresh frozen plasma.

Clinical Pearls

• Diagnostic:
  • Lean Forward: Always instruct patients to lean forward, not backward, to prevent blood aspiration or swallowing, which can cause vomiting.
  • Pressure is Key: Emphasize firm, continuous pressure on the soft part of the nose for at least 10-15 minutes by the clock.
  • Posterior Bleed Clues: If bleeding is profuse, bilateral, or actively draining into the oropharynx despite adequate anterior pressure/packing, suspect a posterior bleed.
  • Visualize: Good lighting, suction, and a nasal speculum are essential to identify the bleeding source. Don't pack blindly if you can localize the source.
  • Consider Systemic Causes: Always inquire about medications, family history of bleeding disorders, and comorbidities, especially for recurrent or severe epistaxis.
• Treatment:
  • Cautery Safety: When using silver nitrate, apply to a discrete bleeding point, avoid excessive application, and do not cauterize both sides of the septum simultaneously to prevent septal perforation.
  • Packing Duration: Generally 24-72 hours for anterior packs, 48-72 hours for posterior packs. Always consider prophylactic antibiotics for non-absorbable packing.
  • Pain Control: Nasal packing can be uncomfortable; provide adequate analgesia.
  • Airway: Posterior packing carries a risk of airway compromise; monitor closely, especially in elderly or sedated patients.
• Pitfalls:
  • Inadequate Pressure: Patients often "pinch the bridge" or release pressure too soon.
  • Overlooking Posterior Bleeds: Treating a posterior bleed as an anterior one will lead to failure.
  • Aggressive Cautery: Can cause septal perforation, especially if bilateral.
  • Ignoring Underlying Causes: Failing to investigate and address systemic factors (e.g., uncontrolled HTN, coagulopathy, medication use).
  • Premature Discharge: Discharging a patient too soon after severe epistaxis without ensuring stability or adequate follow-up.
  • Unilateral Discontinuation of Anticoagulants: Always consult the prescribing physician before altering or stopping critical medications like anticoagulants.

Recent Updates

• Guidelines: The American Academy of Otolaryngology—Head and Neck Surgery (AAO-HNS) and other societies periodically update guidelines, emphasizing a stepwise approach, initial conservative management, and appropriate specialist referral for refractory cases.
• Evidence:
  • Topical Tranexamic Acid (TXA): Growing evidence supports the use of topical TXA for acute epistaxis, showing comparable efficacy to anterior nasal packing in some studies, with potentially fewer complications and greater patient comfort. Systemic TXA is also increasingly used in patients with bleeding disorders or refractory cases.
  • DOAC Reversal: Development and increasing availability of specific reversal agents for direct oral anticoagulants (DOACs) have improved management options for severe bleeding in these patients.
  • Endoscopic Approaches: Continued refinement of endoscopic sphenopalatine artery ligation techniques has made it a highly effective and less invasive surgical option for posterior epistaxis.
• Controversies:
  • Routine Antibiotics for Nasal Packing: While commonly used, the routine use of prophylactic antibiotics for short-term anterior nasal packing remains an area of debate, with some advocating for selective use due to concerns about antibiotic resistance and lack of strong evidence for benefit in all cases.
  • Optimal Timing for Reversal of Anticoagulation: Balancing the risk of thrombosis versus hemorrhage in patients on critical anticoagulation who present with epistaxis remains a clinical challenge, requiring careful individualized decision-making.
