Nasal Polyposis Management

Polyps Primer - Unmasking the Masses

• Benign, pale, edematous, pedunculated or sessile mucosal outgrowths, typically bilateral, originating from middle meatus/ethmoids.
• Pathogenesis: Chronic inflammation (often eosinophilic, with ↑IL-5, IgE), Bernoulli effect (airway narrowing), genetic predisposition (e.g., HLA types).
• Key Associations:
  • Samter's Triad (AERD): Asthma + Aspirin/NSAID hypersensitivity + Nasal Polyps (📌 ASPirin).
  • Cystic Fibrosis (CF): Suspect with bilateral polyps in children; often extensive.
  • Allergic Fungal Rhinosinusitis (AFRS).
  • Kartagener's syndrome, Young's syndrome, Churg-Strauss syndrome (EGPA).

⭐ In children, nasal polyps are strongly associated with Cystic Fibrosis; always rule out CF, especially if bilateral and recurrent before puberty (incidence 6-48%).

Signs & Scans - Spotting the Polyps

• Clinical Features:
  • Nasal obstruction (bilateral, progressive)
  • Anosmia / Hyposmia (↓ sense of smell)
  • Rhinorrhea (clear, mucoid), post-nasal drip
  • Facial pain/pressure, headache
• Examination (Anterior Rhinoscopy & Nasal Endoscopy):
  • Smooth, greyish-white, glistening, pedunculated masses
  • Often bilateral, arising from middle meatus/ethmoids
  • Insensitive to probing, mobile
• Imaging (CT PNS - Non-Contrast):
  • Confirms diagnosis, extent, bony changes (e.g., erosion, remodeling)
  • Lund-Mackay Score (0-24): grades severity (0-2 per sinus)

  ⭐ CT often shows bilateral, diffuse opacification of multiple paranasal sinuses, especially ethmoids, with possible expansion of ethmoid bulla and widening of the osteomeatal complex (OMC).

Pills & Sprays - Taming the Polyps

• Intranasal Corticosteroids (INCS):
  • First-line: ↓inflammation, ↓polyp size.
  • E.g., Fluticasone, Mometasone. Long-term use.
  • Minimal systemic effects.
• Oral Corticosteroids (OCS):
  • Severe symptoms/exacerbations.
  • Short course: Prednisolone 0.5-1 mg/kg/day (5-14 days), then taper.
  • Weigh risks for repeated use.
• Leukotriene Receptor Antagonists (LTRAs):
  • E.g., Montelukast.
  • Adjunct, esp. in Aspirin-Exacerbated Respiratory Disease (AERD).
• Biologics (Monoclonal Antibodies):
  • Severe, refractory CRSwNP; Type 2 inflammation (↑eosinophils, ↑IgE).
  • Target: IL-4, IL-5, IL-13, IgE.
  • E.g., Dupilumab, Mepolizumab, Omalizumab.
  • ↓OCS & surgery need.

⭐ Dupilumab significantly reduces polyp size and symptoms in CRSwNP, with or without asthma.

Scalpel & Scope - Clearing the Path

• Functional Endoscopic Sinus Surgery (FESS): Primary surgical intervention.
  • Indications:
    • Failure of maximal medical therapy (e.g., 3 months INCS + 2-3 weeks OCS)
    • Complications (mucocele, orbital/intracranial spread)
    • Antrochoanal polyps
    • Samter's triad (AERD)
    • Suspicion of malignancy
  • Goals:
    • Remove polyps, restore sinus ventilation & drainage
    • Improve olfaction, enhance topical medication delivery
    • Tissue for histopathology
• Surgical Extent: Tailored; includes polypectomy, ethmoidectomy, maxillary antrostomy, sphenoidotomy, frontal sinusotomy.
• Post-operative Care:
  • Nasal saline irrigation (essential)
  • Long-term intranasal corticosteroids
  • Regular endoscopic debridement

  ⭐ Recurrence of nasal polyps post-FESS is high; continued medical therapy and follow-up are vital.

• Potential Complications: 📌 B.O.C.S.I.
  • Bleeding
  • Orbital injury (diplopia, vision loss)
  • CSF leak (⚠️ Halo sign, β2-transferrin)
  • Synechiae
  • Infection

High‑Yield Points - ⚡ Biggest Takeaways

• Samter's triad (nasal polyps, asthma, aspirin sensitivity) is a key association.
• Bilateral ethmoidal polyps are most common; unilateral raises suspicion for neoplasm or fungal disease.
• Intranasal corticosteroids are first-line medical therapy; oral steroids for severe cases.
• FESS (Functional Endoscopic Sinus Surgery) is indicated for medical failure or extensive polyposis.
• Recurrence is common; long-term postoperative intranasal steroids are essential for prevention.
• Antrochoanal polyps are typically unilateral, originating from the maxillary sinus and extending to the choana.
