Nasal Polyposis

Nasal Polyposis - Polyp Primer

• Definition: Benign, pale, edematous, pedunculated mucosal outgrowths from nasal/sinus lining.
• Types:
  • Ethmoidal Polyps:
    • Bilateral, multiple, grape-like.
    • Adults; often eosinophilic.
    • Associated with asthma, Aspirin Exacerbated Respiratory Disease (AERD), Allergic Fungal Rhinosinusitis (AFRS).
  • Antrochoanal Polyp (Killian's Polyp):
    • Unilateral, solitary.
    • Originates in maxillary antrum, extends to choana/nasopharynx.
    • Commoner in children/young adults.
• Pathogenesis: Chronic inflammation (Th2-driven, eosinophilic in many), epithelial barrier dysfunction, biofilm role.

• ⭐ > In children presenting with bilateral nasal polyps, Cystic Fibrosis (CF) must be excluded.
• 📌 Samter's Triad (AERD): Asthma + Aspirin Sensitivity + Nasal Polyps.

Nasal Polyposis - Symptom Spotlight

• Cardinal Symptoms:
  • Progressive bilateral nasal obstruction (most common)
  • Anosmia / Hyposmia (often a primary complaint, significant impact)
  • Rhinorrhea: mucoid/watery; purulent if secondary infection
  • Post-nasal drip, chronic cough
  • Facial pressure/headache (if extensive or with sinusitis)
• Signs on Examination:
  • Smooth, pale/greyish, glistening, "peeled grape" appearance
  • Typically bilateral, arising from middle meatus/ethmoids
  • Insensitive to probing (differentiates from turbinates)
• Key Systemic Associations:
  • Samter's Triad (AERD: Asthma, Aspirin sensitivity, Nasal Polyps)
  • Cystic Fibrosis (suspect in any child with polyps)
  • Allergic Fungal Rhinosinusitis (AFRS)
  • Churg-Strauss Syndrome (EGPA)

⭐ Samter's Triad (Aspirin Exacerbated Respiratory Disease - AERD) is a crucial association: Nasal Polyps + Bronchial Asthma + Aspirin/NSAID intolerance.

Nasal Polyposis - Detective Work

• Investigations:
  • DNE: Visualize origin, extent, character of polyps.
  • CT PNS: Roadmap for surgery; assess sinus opacification, bony erosion.
  • Biopsy: Mandatory for unilateral/suspicious lesions.
  • Consider: Allergy tests (skin prick/RAST), CF testing (children, recurrent/refractory cases).

⭐ Unilateral nasal polyps or those with atypical features (e.g., bleeding, pain) require urgent biopsy to exclude malignancy or conditions like inverted papilloma.

Nasal Polyposis - Taming the Polyps

Pale, edematous sinonasal mucosal outgrowths due to chronic inflammation (often eosinophilic, Th2-mediated).

• Key Associations: Asthma, Aspirin Exacerbated Respiratory Disease (AERD/Samter's Triad), Cystic Fibrosis (esp. children), Allergic Fungal Rhinosinusitis (AFRS).
• Symptoms: Persistent nasal obstruction, significantly ↓smell (anosmia/hyposmia), chronic rhinorrhea, facial pressure.
• Diagnosis: Clinical exam, nasal endoscopy (reveals characteristic pale, grape-like masses), CT scan (evaluates sinus opacification and bony anatomy).

• Medical Therapy:
  • INS: First-line (e.g., fluticasone, mometasone).
  • OCS: Short courses for severe symptoms/pre-op.
  • Biologics (anti-IgE, anti-IL5/5R, anti-IL4Rα): For severe, recalcitrant Chronic Rhinosinusitis with Nasal Polyps (CRSwNP).
• Surgical: Functional Endoscopic Sinus Surgery (FESS) for failed medical therapy or extensive disease.
• Recurrence: Common; requires long-term management and patient education.

⭐ Samter's Triad (AERD) consists of Nasal Polyps, Bronchial Asthma, and Aspirin Intolerance. 📌 ASA triad.

High‑Yield Points - ⚡ Biggest Takeaways

• Nasal polyps: Typically bilateral, pale, grape-like masses, arising from ethmoidal sinuses (middle meatus).
• Strong association with allergy, asthma, aspirin sensitivity (Samter's Triad); and cystic fibrosis in children.
• Antrochoanal polyp: Usually unilateral, from maxillary sinus to choana, common in children/adolescents.
• Key symptoms include: Nasal obstruction, anosmia/hyposmia, and watery rhinorrhea.
• Management: Intranasal corticosteroids (first-line); FESS for refractory cases.
• High recurrence rate.
