Treatment of Nasal Cartilage Fractures
Surgical correction is the definitive treatment for nasal cartilage fractures, with specific techniques determined by the location and severity of the fracture to prevent long-term functional and cosmetic complications. 1
Diagnostic Approach
The first step in treatment involves proper diagnosis through:
- Clinical examination: Assess for external nasal deformity, nasal airway patency, point tenderness, mobility/crepitus of nasal bones, and septal hematoma or deviation 2
- Imaging: CT is the gold standard for complex nasal injuries, while ultrasound offers an excellent radiation-free alternative with 90-100% sensitivity for isolated nasal fractures 2
- Immediate complications assessment: Check for septal hematoma which must be evacuated immediately to prevent cartilage necrosis and saddle nose deformity 2, 3
Treatment Algorithm Based on Fracture Location
1. Septal Cartilage Fractures
Mild deviations:
- Mobilization, trimming/thinning and suturing to bring the posterior septal angle to midline
- Fixation with permanent 5-0 nylon or PDS 4-0 sutures 1
Moderate deviations:
- "Contralateral subluxation locking" technique for slightly bowed, unilaterally deviated caudal septum
- Repositioning of caudal septum to contralateral side of nasal spine/maxillary crest
- Additional suturing to maintain position 1
Severe deviations:
- Weakening procedures: through-and-through cartilage incisions or castellation (interdigitating incisions)
- Reconstruction with "figure 8" sutures to stabilize adjacent cartilage
- Batten type grafts to reorient and straighten dorsal and caudal septal struts 1
- Consider absorbable plates (PCL mesh or PDS) as internal splints for septal support 4
2. Upper Lateral Cartilage Injuries
- Recognize avulsion injuries which may cause significant concavity and "hollowed out" appearance
- Realign the lateral cartilage to its normal anatomical position to prevent airway obstruction
- Secure with sutures to prevent healing in a distorted position 5
3. Complex Nasal Cartilage Injuries
- Open approach for severe deformities
- Segmental reconstruction using combination of bone and cartilage grafts
- For dorsal defects: cranial bone graft for the upper two-thirds with cartilage component for the lower third 6
- Septal cartilage grafts provide better structural support than conchal cartilage when reconstruction is needed 7
Timing of Intervention
- Acute phase (within 1-2 weeks): Optimal timing for initial reduction and repair
- Early intervention (within 4 weeks): Critical for best correction of deformities 7
- Delayed treatment: May require more extensive reconstructive surgery for functional and cosmetic problems 3
Common Pitfalls to Avoid
- Missing septal hematomas: Must be evacuated immediately to prevent cartilage necrosis and saddle nose deformity 2
- Inadequate treatment of septal fractures: Can lead to nasal obstruction and post-traumatic deformity 4
- Overlooking associated injuries: Nasal fractures may be part of more extensive facial trauma 2
- Relying solely on radiographs: Poor sensitivity and does not alter management 2
- Aggressive morselization: Increases risk of absorption and makes revision difficult 1
