Overview

Historical Perspective

Classification

Pathophysiology

  • The anterior part of the nasal septum consists of a thin cartilaginous layer with closely adherent mucosa and perichondrium.
  • The nasal septum is about 3-4 mm thick and derives its blood supply from the anterior and posterior ethmoid arteries and the sphenopalatine artery.
  • The area known as Kiesselbach plexus is found in the anterior inferior third of the nasal septum, where all the key blood vessels anastomose.
  • When the nasal cartilage is fractured, blood can dissect and form hematoma, which may be bilateral.
  • The exact mechanism underlying the formation of nasal septal hematoma remains controversial.  
  • Septal cartilage is an avascular structure, 2 mm to 4 mm thick, which receives its nutrients supply from the overlying perichondrium.
  • Physicians hypothesize that trauma results in sharp buckling forces that pull the closely adherent mucoperichondrium from the underlying cartilage.
  • This causes the rupture of submucosal vessels which ultimately causes a collection of blood between the cartilage and the perichondrium.
  • Hematoma thus formed, results in pressure-related ischaemic changes and the subsequent necrosis of the septal cartilage.
  • If the trauma is severe enough, the septal cartilage gets fractured, and blood sweeps to the opposite side resulting in a bilateral septal hematoma.
  • This situation is more hazardous as it doubles the compromise on the nutrient supply of septal cartilage and hastens the process of cartilage necrosis.
  • Hematoma acts as an ideal medium for bacterial proliferation and colonization.
  • If left untreated, it gets infected within 72 hours leading to the formation of a septal abscess.

Causes

  • The most common cause of nasal septal hematoma is nasal trauma.
    • Nasal trauma can be secondary to sports injuries, road-side accidents, falls, assault or occupational injuries.
    • Even a minor injury can lead to nasal septal hematoma, especially in children.
  • Nasal septal hematoma without history of injury must look into the suspicion of child abuse.
  • Iatrogenic septal hematoma may arise as a complication of nasal surgeries.
  • Atraumatic septal hematoma is rarely seen in patients with bleeding diathesis or as an adverse effect of antiplatelet/anticoagulant drugs.

Epidemiology and Demographics

  • The exact incidence of nasal septal hematoma is unknown as majority of the cases are undiagnosed.
  • However, from the reported cases of nasal injuries incidence of septal hematoma was 0.8% to 1.6%.

Screening

Natural History, Complications, and Prognosis

Diagnosis

Diagnostic Study of Choice

Nasal septal hematoma is a clinical diagnosis.

History and Symptoms

The majority of patients with nasal septal hematoma presents within within the first 24 to 72 hours after trauma. The most common symptom are

  • Nasal obstruction ( unilateral or bilateral)
  • Pain
  • Rhinorrhea
  • Fever
  • Nasal deformity /Nasal pain

Physical Examination

Clinical examination of nasal septal hematoma is usually confirmatory. Findings on nasal speculum or otoscope include

  • Blood clots, (should be suctioned)
  • Asymmetry of the septum with bluish or reddish mucosal swelling suggests a hematoma.
  • A newly formed hematoma is not always ecchymotic and can only be picked up by palpation.
  • On direct palpation by inserting the little finger feels soft and fluctuant in contrast to deviated nasal septum which will be firm and concave on the opposite side.
  • Another important feature of septal hematoma is the lack of reduction in size on the application of decongestant sprays like oxymetazoline 0.05%.
