Nasal Polyp Treatment
Intranasal corticosteroids are the cornerstone of nasal polyp treatment and should be initiated as first-line therapy, with twice-daily dosing being more effective than once-daily administration. 1
First-Line Medical Management
Initiate intranasal corticosteroids twice daily plus saline nasal irrigation for all patients with nasal polyps. 2, 1
- Fluticasone propionate 400 μg twice daily or budesonide 256 μg twice daily significantly reduces polyp size, improves nasal airflow, and decreases nasal congestion compared to placebo 2, 3
- Twice-daily dosing demonstrates superior efficacy over once-daily regimens in reducing polyp size and improving peak nasal inspiratory flow 1, 3
- Saline nasal irrigation serves as essential adjunctive therapy to clear mucus and enhance medication delivery 2, 1
- Treatment duration should be at least 8-12 weeks to achieve optimal polyp reduction 2, 3, 4
Proper Administration Technique
Patients must use correct intranasal steroid technique to maximize efficacy and minimize adverse effects. 2
- Look downward by bending the neck toward the floor 2
- Use the right hand for the left nostril and left hand for the right nostril 2
- Aim toward the outer nasal wall, not the septum, to prevent epistaxis and irritation 2
- Avoid sniffing hard after administration 2
Escalation for Severe or Refractory Disease
For patients with severe symptoms or inadequate response to intranasal corticosteroids after 8-12 weeks, add a short course of systemic corticosteroids (7-21 days) at 25-60 mg oral prednisolone daily, followed by mandatory maintenance with intranasal corticosteroids. 1, 5
- Systemic corticosteroids significantly reduce total symptom scores and polyp scores within 2-4 weeks 1
- This approach serves as "medical polypectomy" for severe obstruction 6
- Critical pitfall: Relying on systemic corticosteroids alone without maintenance intranasal therapy leads to rapid symptom recurrence 1, 6
Additional Medical Options
- Leukotriene modifiers (montelukast, zafirlukast, zileuton) may provide subjective improvement when added to intranasal corticosteroids 1
- Corticosteroid-eluting sinus implants placed in the ethmoid sinus reduce nasal obstruction, polyp grade, and surgical need (OR 0.34) for patients failing standard therapy 1
- Short-term combination of oxymetazoline plus intranasal corticosteroids (4-6 weeks) may be more effective than intranasal corticosteroids alone without causing rebound congestion 1
Special Population: Aspirin-Exacerbated Respiratory Disease (AERD)
For patients with AERD and nasal polyps, consider aspirin desensitization followed by long-term daily aspirin therapy after initial medical management. 1, 5
- Aspirin desensitization reduces nasal symptoms, frequency of sinus infections, and need for polypectomies 1, 5
- These patients have worse surgical outcomes and higher recurrence rates compared to aspirin-tolerant patients 1, 7
Surgical Intervention
Functional endoscopic sinus surgery (FESS) is indicated when medical treatment fails to adequately control symptoms after appropriate trials of intranasal corticosteroids, systemic corticosteroids, and adjunctive therapies. 1, 7, 8
Surgical Indications
- Severe nasal polyposis causing complete obstruction despite comprehensive medical management 7, 8
- Patients requiring repeated courses of systemic corticosteroids (risks exceed surgical risks) 7
- Unilateral polyps or atypical presentations requiring tissue diagnosis 2
- Extension of polyps outside the nasal cavity 2
Critical Surgical Considerations
- Correction of anatomic obstruction (septal deviation, turbinate hypertrophy) should be performed concurrently to optimize outcomes 7
- Major complications occur in less than 1% of cases 7
- Mandatory post-operative management: Continue intranasal corticosteroids twice daily indefinitely to prevent recurrence 7, 8
- 60-70% of patients maintain polyp control at 18 months with continued post-operative medical therapy 7
- Revision surgery is required in approximately 10% of patients within 3 years 7
Treatment Algorithm Summary
- Initial therapy (all patients): Intranasal corticosteroids twice daily + saline irrigation for 8-12 weeks 2, 1
- If inadequate response: Add short course systemic corticosteroids (7-21 days) followed by maintenance intranasal corticosteroids 1, 5
- If still inadequate: Consider corticosteroid-eluting implants or leukotriene modifiers 1
- If medical failure: Proceed to FESS with mandatory post-operative intranasal corticosteroids 1, 7, 8
Common Pitfalls to Avoid
- Failing to use twice-daily dosing of intranasal corticosteroids reduces treatment efficacy 1, 3
- Improper administration technique (aiming toward septum) causes epistaxis and poor drug delivery 2
- Discontinuing intranasal corticosteroids after systemic steroid course or surgery leads to rapid recurrence 1, 7, 6
- Using nasal decongestants alone without corticosteroids causes rebound congestion 1
- Not identifying comorbid asthma, AERD, or allergic fungal rhinosinusitis results in suboptimal outcomes 1, 5
- Assuming surgery alone will cure the condition—nasal polyposis is a chronic inflammatory disease requiring lifelong medical management 8, 5
