No, nasal cones are not indicated for treatment of deviated nasal septum
Nasal cones (external nasal dilators) are not a treatment for septal deviation itself—they may provide temporary symptomatic relief in select cases but do not address the underlying structural deformity. The definitive treatment for symptomatic deviated nasal septum remains surgical correction through septoplasty 1.
Understanding the Role of External Nasal Dilators
External nasal dilators can temporarily improve nasal airflow in patients with septal deviation affecting the nasal valve area, but this effect is purely mechanical and does not correct the anatomical problem 2. Research shows:
- Objective improvement without subjective benefit: While external dilators increased minimum cross-sectional area and decreased nasal resistance in patients with septal deviation (P < 0.001), patients with mucosal congestion did not experience a corresponding sensation of improved breathing 2
- Limited application: The effect is most pronounced when deviation specifically obstructs the nasal valve area, not for deviations throughout the septum 2
Definitive Treatment: Septoplasty
Septoplasty provides significant and sustained improvement in nasal obstruction symptoms and quality of life compared to non-surgical management 3, 4. The evidence demonstrates:
Symptom Improvement
- NOSE scores improved significantly at 6 months (MD -28.73,95% CI -33.44 to -24.03) and 12 months (MD -17.27,95% CI -22.85 to -11.69) 3
- SNOT-22 scores showed greatest benefit at 6 months (MD -9.64,95% CI -12.66 to -6.62) 3
- Quality of life improvements sustained at 6 and 12 months post-surgery 4
Safety Profile
Septoplasty has a favorable safety profile with low complication rates:
- Revision rate: 0.31%
- Bleeding and infection: 4.12%
- Overall complications remain minimal 4
Surgical Principles for Septal Correction
The guideline literature emphasizes that "as the septum goes, so goes the nose"—septal correction is fundamental to addressing nasal deviation 1. Modern surgical approach includes:
- Systematic analysis: Divide the nose into horizontal thirds (upper, middle, lower) to identify which components require correction 1
- Conservative tissue preservation: Use suture fixation, locking techniques, and cartilage shaving rather than aggressive resection 1
- Autogenous cartilage grafts: For repositioning, reinforcement, and reconstruction to increase stability of the realigned framework 1
Clinical Algorithm
- Symptomatic septal deviation with nasal obstruction → Septoplasty is indicated (age ≥6 years for pediatric cases) 5
- Mild symptoms or patient preference to delay surgery → Medical management (topical decongestants, nasal steroids) as temporizing measure
- External nasal dilators → May be considered as adjunct for temporary relief while awaiting surgery, particularly if valve area is affected 2, but should not be viewed as definitive treatment
Critical Pitfall to Avoid
Do not mistake temporary symptomatic relief from external devices as treatment of the underlying structural problem. A customized nasal dilator device has been described as "an adjunct to treatment" and "a breather until the patient receives definitive treatment" 6—this clearly positions such devices as temporizing measures, not therapeutic solutions.
The bottom line: Nasal cones/external dilators are not treatment for deviated septum. They may provide temporary symptomatic relief in select cases but septoplasty remains the definitive treatment for patients with symptomatic nasal obstruction due to septal deviation 3, 4.
