A 48-year-old man with a 6-month history of nasal congestion, recurrent purulent nasal discharge, post-nasal drip, and facial pain presents to the ENT clinic. He reports that symptoms are worse in the morning and improve partially with nasal decongestants. He has completed three courses of antibiotics in the past 4 months with temporary relief followed by recurrence. Nasal endoscopy shows nasal polyps, and CT scan of the paranasal sinuses reveals bilateral maxillary and ethmoid sinus opacification with polypoid changes. What is the most appropriate next step in management?

Explanation

## Clinical Diagnosis **Key Point:** This patient has chronic rhinosinusitis with nasal polyposis (CRSwNP) that is refractory to medical management. ## Chronic Rhinosinusitis: Definition and Criteria Symptoms lasting >12 weeks (this patient: 6 months) with endoscopic or radiologic evidence of sinus inflammation: - Nasal congestion/obstruction - Post-nasal drip - Facial pain/pressure - Anosmia (loss of smell) **High-Yield:** Chronic sinusitis is defined by **duration (>12 weeks)**, not severity. Recurrent acute sinusitis (≥4 episodes/year) is a separate entity. ## Management Algorithm for CRSwNP ```mermaid flowchart TD A[Chronic Rhinosinusitis with Nasal Polyps]:::outcome --> B[Start Medical Management]:::action B --> C[Topical nasal corticosteroid spray]:::action C --> D[Saline irrigation]:::action D --> E{Response after 4-6 weeks?}:::decision E -->|Yes| F[Continue medical therapy]:::action E -->|No| G[Add short course oral corticosteroid]:::action G --> H{Response after 2-4 weeks?}:::decision H -->|Yes| F H -->|No| I[FESS with polypectomy]:::action I --> J[Postoperative topical corticosteroid]:::action J --> K[Long-term follow-up]:::outcome ``` ## First-Line Medical Management | Intervention | Indication | Duration | |--------------|-----------|----------| | Topical nasal corticosteroid spray | All CRSwNP | Long-term (months–years) | | Saline irrigation | All CRSwNP | Long-term | | Short-course oral corticosteroid | Severe symptoms, failed topical therapy | 2–4 weeks | | Antibiotics | Acute exacerbation only | 7–14 days | **Clinical Pearl:** Topical nasal corticosteroids (fluticasone, mometasone, budesonide) are the cornerstone of CRSwNP management. They reduce polyp size and symptoms in 60–70% of patients. ## Indications for FESS 1. **Failed medical management** after 4–6 weeks of topical corticosteroid + saline irrigation 2. **Severe symptoms** affecting quality of life despite medical therapy 3. **Complications** (orbital, intracranial involvement) 4. **Concurrent conditions** requiring surgical intervention (e.g., deviated septum, sinus ostial obstruction) **High-Yield:** This patient has failed multiple courses of antibiotics and has objective findings (polyps on endoscopy, bilateral sinus opacification on CT). He is a clear candidate for FESS. ## Why Each Option Is Inappropriate ### Option A: Long-term oral corticosteroids - Systemic corticosteroids carry significant side effects (osteoporosis, immunosuppression, adrenal suppression) when used long-term - Topical corticosteroids are preferred for chronic management - Oral corticosteroids may be used as a **short-term bridge** (2–4 weeks) before FESS, not as monotherapy ### Option C: Topical corticosteroid spray alone - This is appropriate as **first-line** medical therapy - However, this patient has already failed multiple antibiotics and has significant symptoms - He requires escalation to FESS, not de-escalation to topical therapy alone ### Option D: Intranasal amphotericin B - Reserved for invasive fungal sinusitis (rare, immunocompromised patients) - This patient has no risk factors for fungal infection - CT findings are consistent with chronic rhinosinusitis with polyps, not fungal disease [cite:Fokkens WJ et al.
