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.
Differentiating Nasal Septal Hematoma from other Diseases
Nasal septal hematoma must be differentiated from other diseases with similar presentation
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%.
Risk Factors
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%.
