Nasal septal hematoma (NSH) is a subperichondrial collection of blood between the septal cartilage and its overlying mucoperichondrium. It is a rare but true ENT emergency — the avascular septal cartilage depends entirely on the mucoperichondrium for its blood supply, and separation by hematoma leads to cartilage ischemia and necrosis within days if untreated. [1-3] This condition is frequently missed: in one pediatric series, 82% of cases were initially missed in the ED, with a median time to diagnosis of 7 days and an average of 2.2 evaluations before diagnosis. [4]
The following figure illustrates the pathophysiology — blood accumulating in the subperichondrial space, stripping the cartilage from its sole blood supply.
1. History
- Mechanism of injury: Direct nasal trauma (assault, sports, fall, MVA) — present in ~85% of cases [4-5]
- Timing: Onset of progressive bilateral nasal obstruction and pain after trauma; may develop acutely or with delayed onset up to 48–72 hours post-injury [6]
- Key symptoms: Nasal congestion/obstruction (bilateral and progressive), nasal pain, pressure sensation, rhinorrhea, epistaxis [1][7-8]
- Symptom progression: Worsening obstruction despite decongestants; new-onset fever or purulent discharge suggests abscess formation [7]
- Important negatives: Absence of fever, purulent drainage, or facial cellulitis helps distinguish hematoma from abscess
2. Alarm Features
- Fever + purulent nasal discharge → suspect progression to septal abscess (mean symptom duration for abscess ~7.6 days vs ~4.1 days for hematoma) [7]
- Saddle nose deformity developing → cartilage necrosis has already occurred
- Headache, periorbital swelling, visual changes, altered mental status → intracranial complications: meningitis, cavernous sinus thrombosis, intracranial abscess, subdural empyema [2][9]
- Bilateral septal swelling in any post-trauma patient is a hematoma until proven otherwise
- Brain abscess has been reported as a fatal complication of infected septal hematoma [10]
3. Medications
- Prophylactic antibiotics: Generally recommended after drainage to prevent abscess formation; anti-staphylococcal coverage is standard (e.g., amoxicillin-clavulanate, first-generation cephalosporin) [2][11]
- If abscess suspected or confirmed: Parenteral broad-spectrum antibiotics covering Staphylococcus aureus (isolated in ~70% of cases), including MRSA coverage in at-risk patients [2][12]
- In children, also consider coverage for H. influenzae and S. pneumoniae [13]
- Medications to review: Anticoagulants, antiplatelets, NSAIDs (may contribute to hematoma formation, though one study found no significant correlation with coagulopathy) [1]
- Topical decongestants (oxymetazoline) may be used adjunctively for mucosal decongestion during examination
4. Diet
- No specific dietary triggers or recommendations
- Ensure adequate hydration, especially in pediatric patients
- Avoid hot liquids/foods that may promote vasodilation and re-bleeding in the immediate post-drainage period
5. Review of Systems
- ENT: Nasal obstruction (bilateral vs unilateral), epistaxis, rhinorrhea (clear vs purulent), anosmia, facial pain/pressure
- Neurologic: Headache, vision changes, altered mental status, facial numbness (may indicate intracranial extension) [14]
- Constitutional: Fever, chills, malaise (suggest infection/abscess)
- Dental: Recent dental procedures or infections (rare cause of septal abscess)
6. Collateral History and Family History
- Collateral: Witnesses to mechanism of injury; timing and force of trauma; prior nasal surgeries or procedures (septoplasty, rhinoplasty, cauterization for epistaxis) [14-15]
- Family history: Bleeding disorders (von Willebrand disease, hemophilia) — though coagulopathy was not significantly associated with NSH incidence in one large series [1]
- Social context: Sports participation (contact sports), interpersonal violence, child abuse (consider non-accidental trauma in pediatric cases with inconsistent history)
7. Risk Factors
- Nasal trauma (most common cause — ~85%) [4]
- Nasal/sinus surgery or procedures (septoplasty, rhinoplasty, cauterization) [14-15]
- Male sex (92% male in pediatric series) [4]
- Pediatric age group (children are more susceptible; mean age ~7 years in pediatric studies) [7]
- Anticoagulant/antiplatelet use (theoretical risk, though not statistically confirmed) [1]
- Diabetes mellitus (particularly for progression to abscess — present in 47% of adult abscess cases in one series) [16]
- Immunocompromised states [8]
- Nose-picking (44% of adult abscess cases in one series) [16]
8. Differential Diagnosis
- Nasal septal abscess — the most dangerous progression; distinguished by fever, purulent discharge, fluctuance, and longer symptom duration [2][7]
- Deviated nasal septum — chronic, non-tender, firm on palpation (not boggy/fluctuant)
- Nasal polyps — typically pale, glistening, non-tender, insensate
- Inferior turbinate hypertrophy — lateral nasal wall, not septal; a common misdiagnosis [17]
- Nasal foreign body (pediatric) — unilateral, foul-smelling discharge
- Nasal bone fracture without hematoma — external deformity, crepitus, but no septal swelling
- Sinonasal neoplasm — unilateral obstruction, epistaxis, consider in non-traumatic presentations
9. Past Medical History
- Prior nasal trauma or fractures
- Previous nasal/sinus surgery
- Bleeding disorders or coagulopathy
- Diabetes mellitus (risk factor for abscess formation) [12][16]
- Immunosuppression (HIV, chemotherapy, chronic steroids)
- History of recurrent epistaxis or cauterization procedures [14]
10. Physical Exam
- Anterior rhinoscopy (essential — use nasal speculum or otoscope with largest ear speculum):
- Pathognomonic finding: Bilateral, boggy, bluish-red, fluctuant swelling of the nasal septum that narrows or obliterates both nasal passages [1][18]
- Palpation with cotton-tipped applicator: soft, compressible, fluctuant mass (distinguishes from deviated septum, which is firm)
- Painful septal swelling combined with nasal obstruction was present in 100% of NSH patients [1]
- External nose: Swelling, ecchymosis, deformity, tenderness, crepitus (assess for concurrent nasal fracture)
- Assess for abscess: Erythema, warmth, purulent drainage, fever
- Vital signs: Fever suggests infection/abscess progression
- Neurologic exam: If concern for intracranial complications
11. Lab Studies
- Routine labs are generally not required for uncomplicated septal hematoma
- If abscess suspected or drained:
- Culture and sensitivity of aspirated material (S. aureus in ~70%, including MRSA) [2][12]
- CBC with differential (leukocytosis suggests infection)
- Blood glucose / HbA1c (screen for undiagnosed diabetes, especially in spontaneous abscess) [12][16]
- Coagulation studies (PT/INR, PTT) if bleeding disorder suspected or patient on anticoagulants
12. Imaging
- Imaging is generally unnecessary for straightforward clinical diagnosis — NSH is a clinical diagnosis made by anterior rhinoscopy [1]
- CT face/sinuses (with contrast): Indicated if:
- Concern for concurrent facial fractures
- Suspected intracranial or orbital complications
- Posterior septal abscess suspected (not visible on anterior rhinoscopy) [9]
- MRI head with contrast: Superior for detecting intracranial complications (meningitis, cavernous sinus thrombosis, brain abscess) — 97% diagnostic accuracy vs 87% for CT [19]
- Key imaging findings: Subperichondrial fluid collection along the septum; rim enhancement suggests abscess
13. Special Tests
- Cotton-tipped applicator palpation test: Gently press on the septal swelling — fluctuance and compressibility confirm hematoma vs firm deviated septum (the single most important bedside maneuver)
- Needle aspiration: Can be both diagnostic and partially therapeutic — aspiration of non-clotted blood confirms hematoma; purulent material confirms abscess
- No validated scoring systems exist for NSH
14. ECG
- Not routinely indicated
- Consider if trauma mechanism raises concern for associated injuries (e.g., blunt chest trauma, syncope preceding fall)
15. Assessment
NSH is a rare but frequently missed ENT emergency. The critical clinical pearl is that every patient with nasal trauma must have an anterior rhinoscopy to evaluate the septum. [13][20] The condition was missed in 46% of cases across multiple clinical settings in one pediatric study. [4] Untreated hematoma progresses to abscess (typically within days), cartilage necrosis, and potentially life-threatening intracranial infection. Long-term sequelae are common: 61.7% of patients experienced minor or major sequelae in one long-term follow-up study (mean 8.7 years), including saddle nose deformity (the most common major complication). [7-8] In children, cartilage destruction also impairs midface growth. [2][21]
16. Treatment Plan
Initial stabilization
- Manage concurrent injuries (epistaxis control, facial fracture assessment)
- Analgesia as needed
Definitive treatment — Incision and Drainage (I&D)
- Urgent drainage is required — ideally within 24–48 hours of diagnosis [5][11]
- Technique: Hemitransfixion incision through the mucoperichondrium; evacuate clot; irrigate
- Prevent re-accumulation: Quilting sutures through the septum, placement of a small drain (e.g., Penrose), and/or bilateral anterior nasal packing [11]
- Re-collection rate after I&D is low (~3.6%) [11]
- In adults, can often be performed under local anesthesia in the ED; most pediatric cases require general anesthesia [11]
Antibiotics
- Prophylactic oral antibiotics post-drainage (anti-staphylococcal coverage: amoxicillin-clavulanate or first-generation cephalosporin) [11]
- If abscess: IV broad-spectrum antibiotics with MRSA coverage in at-risk patients [12]
If cartilage destruction has occurred (abscess)
17. Disposition
- Small, uncomplicated hematoma drained in the ED → may be discharged with close ENT follow-up within 24–48 hours for re-examination and packing removal
- Admit if:
- Septal abscess confirmed or suspected
- Need for IV antibiotics
- Pediatric patient requiring OR drainage under general anesthesia
- Signs of systemic infection or intracranial complications
- Significant comorbidities (uncontrolled diabetes, immunosuppression)
- ENT consultation: Should be obtained for all confirmed cases; urgent/emergent for abscess or complicated presentations [4]
18. Follow Up / Return Precautions
- Follow-up: ENT re-evaluation within 24–48 hours post-drainage for packing removal and assessment for re-collection [6]
- Consider re-evaluation at 48–72 hours post-trauma even if initial exam was negative, as delayed hematoma formation has been reported [6]
- Return precautions — instruct patients/parents to return immediately for:
- Worsening nasal obstruction
- New-onset fever
- Purulent nasal discharge
- Increasing facial pain or swelling
- Headache, vision changes, or confusion
- Long-term follow-up: Monitor for saddle nose deformity, septal perforation, and (in children) midface growth abnormalities [7][21]
- Expected course: With prompt drainage, most patients recover without sequelae; 50% of hematoma patients had no long-term sequelae vs only 7.7% of abscess patients [7]
