What Does a Nasal Hematoma Look Like?
A nasal septal hematoma appears as a painful, boggy, bluish-red swelling of the nasal septum that causes bilateral nasal obstruction, typically occurring after nasal trauma. This is a clinical emergency requiring immediate recognition and drainage to prevent devastating complications like septal cartilage necrosis and saddle nose deformity.
Clinical Appearance
Visual characteristics:
- Bilateral septal swelling that appears as smooth, rounded bulges protruding from both sides of the nasal septum
- Bluish-red or purple discoloration of the septal mucosa
- Boggy, fluctuant texture on palpation (feels like a fluid-filled sac rather than firm tissue)
- The swelling typically obscures the normal midline septum when looking into the nostrils
Key Distinguishing Features
Cardinal symptoms that identify nasal septal hematoma:
- Nasal obstruction - present in nearly 100% of cases, typically bilateral 1, 2, 3
- Nasal pain - occurs in approximately 50% of patients 3
- Recent history of nasal trauma - present in 85-100% of cases 1, 2, 3
The combination of painful septal swelling with nasal obstruction after trauma is pathognomonic for nasal septal hematoma and was exclusively observed in affected patients 1.
Critical Timing Considerations
Delayed diagnosis is common and dangerous:
- Mean time from trauma to diagnosis is 7-8 days 2, 4
- Patients average 2.2 medical evaluations before diagnosis 2
- Diagnosis is frequently missed in emergency departments (82% of cases), primary care (55%), and even otolaryngology clinics (18%) 2
This delay matters because:
- Septal cartilage destruction occurs when diagnosis is delayed
- Abscess formation develops in patients with hematomas left untreated
- Saddle nose deformity occurred in 23% of patients with delayed diagnosis 2
Examination Technique
To identify a nasal septal hematoma:
- Perform anterior rhinoscopy after removing any blood clots
- Look for bilateral septal swelling that narrows or occludes both nasal passages
- Palpate the septum gently - hematomas feel fluctuant/boggy rather than firm
- The normal firm midline septum will be replaced by soft, compressible swelling
Common Pitfalls to Avoid
Why hematomas get missed:
- Focusing only on external nasal deformity or fracture while neglecting internal examination
- Assuming nasal obstruction is just from mucosal edema or dried blood
- Not examining the septum specifically in all nasal trauma patients
- Failing to palpate the septum to assess for fluctuance
The incidence is actually very low (0.6% of nasal fractures) 1, but the consequences of missing it are severe - including cartilage destruction, abscess formation, and permanent saddle nose deformity in 14-23% of cases 2, 4.
Less Common Variants
Alar cartilage hematoma can also occur, presenting as:
- Swelling and deformity of the nasal ala (lateral nasal wall)
- Nasal pain and epistaxis
- Visible external nasal deformity 5
This is even rarer than septal hematoma but requires the same urgent surgical drainage.
When Hematoma Progresses to Abscess
If untreated, hematomas become infected abscesses within days, presenting with:
- Fever (25% of cases) 3
- Increased pain and swelling
- Rhinorrhea (35% of cases) 3
- Systemic signs of infection
Abscess formation is universally associated with septal cartilage destruction 3, making early recognition of the hematoma stage critical.
Bottom line: Any patient with bilateral nasal obstruction and septal swelling after nasal trauma has a nasal septal hematoma until proven otherwise and requires immediate otolaryngology evaluation for surgical drainage 2, 3, 6.
