A 52-year-old man from Mumbai presents with a 6-month history of bilateral nasal obstruction, post-nasal drip, and chronic facial pressure. He reports recurrent episodes of acute sinusitis (3 times in the past year), each treated with antibiotics. On nasal endoscopy, he has bilateral nasal polyps, edematous mucosa, and purulent discharge in the middle meatus. CT paranasal sinuses shows opacification of maxillary and ethmoid sinuses bilaterally with polypoid changes. Allergy testing is negative. What is the most appropriate next step in management?

Explanation

## Clinical Diagnosis This patient has **chronic rhinosinusitis with nasal polyps (CRSwNP)**, evidenced by: - Symptoms >12 weeks (6 months) - Bilateral nasal polyps on endoscopy - Recurrent acute exacerbations - CT evidence of chronic sinus disease - Negative allergy testing (rules out allergic rhinitis as primary cause) ## Management Algorithm for CRSwNP ```mermaid flowchart TD A[Chronic Rhinosinusitis with Nasal Polyps]:::outcome A --> B[Medical Management First]:::action B --> C[Topical Nasal Steroids]:::action C --> D[Saline Irrigation]:::action D --> E[8-12 weeks trial]:::action E --> F{Response to Medical Therapy?}:::decision F -->|Yes: Symptom improvement| G[Continue Medical Management]:::action F -->|No: Persistent symptoms/obstruction| H[FESS with Polypectomy]:::action F -->|Recurrent polyps| I[Consider Biologic Therapy]:::action H --> J[Post-op topical steroids]:::action ``` **Key Point:** Medical management is ALWAYS the first-line approach in CRSwNP, even with bilateral polyps. Surgery is reserved for failure of medical therapy or significant obstruction refractory to medical treatment. ## First-Line Medical Management ### Topical Nasal Corticosteroids - **Mechanism:** Reduce mucosal inflammation, polyp size, and symptoms - **Efficacy:** 50–70% of patients show significant improvement - **Duration:** Minimum 8–12 weeks before assessing response - **Examples:** Mometasone furoate, fluticasone propionate, beclomethasone - **High-Yield:** Topical steroids are superior to oral steroids and have minimal systemic absorption ### Nasal Saline Irrigation - Mechanical clearance of secretions and inflammatory mediators - Improves mucociliary clearance - Safe, adjunctive therapy ### Monitoring - **Clinical review at 8–12 weeks** with repeat nasal endoscopy - **Repeat imaging** only if considering surgery or if symptoms worsen - Assess for polyp size reduction and symptom improvement **Clinical Pearl:** Up to 50% of patients with CRSwNP respond adequately to topical steroids alone and do not require surgery. Polyps may regress significantly with prolonged topical steroid use. ## Indications for Surgery (FESS) 1. Failure of medical therapy after 8–12 weeks 2. Severe nasal obstruction despite medical management 3. Recurrent acute sinusitis despite optimal medical therapy 4. Complications (orbital/intracranial) 5. Suspicion of malignancy **This patient does NOT yet meet criteria for surgery** — medical therapy has not been optimized. ## Why Other Options Are Wrong **High-Yield:** Remember the stepwise approach: **Medical first, surgery second.** - **Immediate FESS:** Premature. Medical therapy has not been attempted or optimized. Guidelines recommend 8–12 weeks of topical steroids before considering surgery. - **Long-term oral antibiotics:** Ineffective for CRSwNP. Antibiotics are for acute exacerbations, not chronic polyp disease. Prolonged use risks resistance. - **Allergy desensitization:** Patient has negative allergy testing. CRSwNP is not primarily allergic in this case; desensitization is not indicated. [cite:Scott-Brown's Otorhinolaryngology Ch 4, EPOS 2020 Guidelines]
