Treatment of Nasal Polyps and Concha Bullosa
Intranasal corticosteroids administered twice daily are the cornerstone first-line treatment for nasal polyps, with short courses of oral corticosteroids reserved for severe cases or inadequate response to topical therapy. 1, 2
First-Line Medical Management
Start with intranasal corticosteroids twice daily as the primary treatment, which significantly reduces polyp size, nasal congestion, and improves sense of smell 1, 2
Twice-daily dosing is more effective than once-daily dosing for optimal polyp control 1, 2
Specific agents with proven efficacy include:
Add nasal saline irrigation as adjunctive therapy to improve mucus clearance and medication delivery 1
Treatment for Severe or Inadequate Response
- For severe nasal polyposis or inadequate response to intranasal corticosteroids alone, prescribe a short course of oral corticosteroids (prednisone 25-60 mg daily for 7-21 days) followed by maintenance with intranasal corticosteroids 1, 2
- Meta-analyses demonstrate that short courses of systemic corticosteroids significantly reduce total symptom scores and nasal polyp scores within 2-4 weeks 1
- Critical caveat: Maintenance therapy with intranasal corticosteroids after the oral steroid course is essential to prevent symptom recurrence 1, 2
Advanced Treatment Options
- For patients with inadequate response to standard medical therapy, consider corticosteroid-eluting sinus implants placed in the ethmoid sinus, which significantly reduce nasal obstruction, polyp grade, and need for surgery (OR 0.34) 1
- Leukotriene modifiers (montelukast 10 mg daily) may provide subjective improvement when added to intranasal corticosteroids, though evidence is mixed 1, 2
- For patients with aspirin-exacerbated respiratory disease (AERD) and nasal polyps, aspirin desensitization followed by long-term daily aspirin therapy may reduce nasal symptoms, frequency of sinus infections, and need for polypectomies 1, 2
Biologic Therapy
- Dupilumab 300 mg subcutaneously every 2 weeks is FDA-approved for chronic rhinosinusitis with nasal polyps in patients aged 12 years and older with inadequate control on standard therapy 6
Surgical Management
- Functional endoscopic sinus surgery (FESS) is indicated when medical treatment fails to adequately control symptoms 1
- Patients with AERD typically have worse surgical outcomes compared to aspirin-tolerant patients 1, 2
- Post-operative maintenance with intranasal corticosteroids prevents polyp recurrence significantly better than placebo (RR 0.73,95% CI 0.56 to 0.94) 5
Treatment Algorithm
- Initial therapy: Intranasal corticosteroids (fluticasone 200 mcg or equivalent) twice daily + saline irrigation 1, 2
- If inadequate response after 8-12 weeks: Add short course of oral prednisone 25-60 mg daily for 7-21 days, then continue intranasal corticosteroids 1, 2
- If still inadequate: Consider corticosteroid-eluting implants, leukotriene modifiers, or biologic therapy (dupilumab) 1, 6
- If medical management fails: Proceed to functional endoscopic sinus surgery with post-operative intranasal corticosteroids 5, 1
Regarding Concha Bullosa
- Concha bullosa (pneumatization of the middle turbinate) is an anatomical variant, not a disease requiring treatment unless it contributes to obstruction or recurrent sinusitis
- If concha bullosa is causing significant obstruction or contributing to chronic rhinosinusitis, surgical reduction may be considered during functional endoscopic sinus surgery
- Isolated concha bullosa without symptoms does not require treatment
Common Pitfalls to Avoid
- Do not rely on short courses of systemic corticosteroids alone without maintenance intranasal corticosteroids, as this leads to rapid symptom recurrence 1, 2
- Avoid nasal decongestants for chronic use in nasal polyps due to risk of rebound congestion 2
- Do not use once-daily dosing of intranasal corticosteroids when twice-daily dosing has superior efficacy 1, 2
- Failing to identify comorbid conditions such as asthma, AERD, or allergic fungal rhinosinusitis leads to suboptimal outcomes 1
- Patients with previous sinus surgery have significantly greater polyp size reduction with intranasal corticosteroids (RR 0.31) compared to those without prior surgery (RR 0.54) 5
