Timing and Technique for Closed Reduction of Nasal Fracture
Perform closed reduction within 1-2 weeks of injury, ideally within 14 days, using general anesthesia or deep sedation with reduction of both nasal bones and septum, followed by internal and external splinting. 1, 2
Optimal Timing Window
- Reduction should be performed within 14 days of injury, with the sweet spot being 1-2 weeks post-injury for highest patient satisfaction (mean satisfaction score 4.56) 3
- Earlier intervention within 2 weeks is feasible and can be performed successfully, with some evidence supporting assessment and manipulation as early as 5-6 days post-injury 4, 2
- Patient satisfaction decreases significantly when surgery is delayed beyond 2 weeks, with 96% of satisfied patients having their procedure within 4 weeks 3
- Assessment at 7-10 days post-injury has traditionally been recommended, though earlier assessment (before 7 days) is feasible 4
Surgical Technique: Five Critical Concepts
The closed reduction technique should incorporate these essential elements 1:
1. Patient Selection
- Appropriate for isolated nasal and septal fractures without severe septal involvement 1
- Caveat: Patients with significant septal involvement have measurably higher rates of subsequent open treatment, so consider delayed open approach (>3 months) for complex septal deformities 5
2. Anesthesia
- General anesthesia or deep sedation is required for adequate reduction 1
- Local nerve blocks alone are insufficient for complete reduction, though dedicated clinics using local anesthesia can reduce time to manipulation 4
3. Reduction Technique
- Reduce both the septum AND nasal bones - not just the external nasal pyramid 1
- Address the septum first, as "the septum goes, so goes the nose" 6
- For septal reduction: mobilize, trim/thin, and suture the caudal septum to midline using 5-0 nylon or 4-0 PDS sutures 6
4. Support/Splinting
- Apply both internal (intranasal) and external splints postoperatively 1
- This dual splinting approach is critical for maintaining reduction and preventing displacement
5. Timing (as above)
Expected Outcomes and Revision Rates
- Closed reduction has a revision rate of 3.9-11.3% requiring subsequent septorhinoplasty 1, 7
- Most common complications include postoperative deformity (11.2%), nasal obstruction (6.1%), and olfactory disturbances (1.1%) 2
- Key predictor of failure: Subjective airway obstruction at cast removal after closed reduction strongly predicts need for revision rhinoplasty 7
- Patients with associated septum fractures are significantly more likely to require revision rhinoplasty 7
Critical Pitfall to Avoid
Do not perform closed reduction on nasal bones alone without addressing the septum - this is the most common technical error leading to poor outcomes and need for revision 1. The septum determines nasal shape and position, and failure to reduce septal deviations will result in persistent deformity regardless of how well the nasal bones are reduced 6.
Alternative Approach for Complex Cases
For severe septal involvement, dorsal/caudal L-strut deformities, or nasal valve issues, consider delayed open septorhinoplasty (>3 months) rather than early closed reduction, as this has lower revision rates and improved ability for rigid fixation 5.
