A 52-year-old man with a 2-year history of recurrent nasal congestion, chronic post-nasal drip, and anosmia presents with persistent facial pressure and nasal obstruction despite three courses of antibiotics in the past year. Examination reveals pale, boggy nasal mucosa bilaterally and multiple smooth, grayish masses obstructing the nasal passages. Nasal endoscopy shows polyps originating from the maxillary and ethmoid sinuses. CT imaging demonstrates opacification of the maxillary and ethmoid sinuses with smooth, rounded densities. What is the most appropriate next step in management?

Explanation

## Diagnosis and Management: Chronic Rhinosinusitis with Nasal Polyps ### Clinical Presentation The patient presents with classic features of chronic rhinosinusitis with nasal polyps (CRSwNP): - **Duration:** 2 years (chronic = >12 weeks) - **Symptoms:** Nasal congestion, post-nasal drip, anosmia, facial pressure - **Examination:** Pale, boggy mucosa; smooth, grayish polyps bilaterally - **Imaging:** CT opacification with smooth, rounded densities (polyps) - **Failed therapy:** Three courses of antibiotics — but **no documented trial of corticosteroids** ### Why Oral Corticosteroids Are the Most Appropriate Next Step **High-Yield:** Per standard ENT guidelines (Scott-Brown's Otorhinolaryngology; Cummings Otolaryngology), the management of CRSwNP follows a stepwise approach: 1. **First-line medical therapy:** Intranasal corticosteroids ± saline irrigation 2. **For moderate-to-severe or refractory polyps:** A short course of **oral (systemic) corticosteroids** (e.g., prednisolone 0.5–1 mg/kg/day for 1–2 weeks) is used to rapidly reduce polyp burden and inflammation 3. **Surgery (FESS):** Reserved for patients who have **failed adequate medical therapy**, including a documented trial of corticosteroids **Key Point:** This patient has failed three courses of antibiotics, but antibiotics are NOT the primary medical therapy for nasal polyps — they target bacterial infection, not the underlying eosinophilic/inflammatory pathology. The patient has **not yet received corticosteroid therapy**, which is the cornerstone of medical management for CRSwNP. Proceeding directly to FESS without a corticosteroid trial would be premature and not in line with evidence-based guidelines. ### Management Algorithm | Step | Therapy | This Patient | |------|---------|-------------| | 1 | Intranasal corticosteroids + saline | Not yet tried | | 2 | Oral corticosteroids (short course) | **Most appropriate next step** | | 3 | FESS with polypectomy | If corticosteroids fail | | 4 | Post-op intranasal corticosteroids | After surgery | ### Why Other Options Are Incorrect - **A (Intranasal corticosteroids alone):** Appropriate for mild disease; given the severity (bilateral polyps, anosmia, 2-year duration), a systemic corticosteroid course is more appropriate to achieve rapid reduction in polyp burden before reassessment. - **B (FESS with polypectomy):** Indicated after failure of adequate medical therapy including corticosteroids. Jumping to surgery without a corticosteroid trial is premature. - **D (Extended-spectrum antibiotics):** Antibiotics do not address the inflammatory/eosinophilic pathology of nasal polyps and are not indicated here. **Clinical Pearl:** Oral corticosteroids produce a rapid, significant reduction in polyp size and symptom burden in CRSwNP. They serve both a therapeutic and diagnostic role — patients who respond well may avoid surgery; those who fail or relapse quickly are then referred for FESS. This "medical polypectomy" approach is standard practice per Scott-Brown's and Cummings. **Mnemonic: CRSwNP Medical Therapy — COINS** - **C**orticosteroids (intranasal first, then oral for moderate-severe) - **O**ral steroids for acute exacerbations/significant polyp burden - **I**rrigation (saline) - **N**ext step = FESS if medical therapy fails - **S**urveillance post-operatively
