Diagnostic Criteria for Chronic Rhinosinusitis with Nasal Polyps

Nasal polyps are benign inflammatory masses, arising from the mucosa of the nose and paranasal sinuses. They are considered to be a subgroup of chronic rhinosinusitis, and clinical diagnosis is made on the basis of the presence of sinonasal symptoms for more than 3 months and the visualization of polyps in the nasal cavity.

Diagnostic Criteria for Chronic Rhinosinusitis with Nasal Polyps

Inflammation of the nose and paranasal sinuses that is characterized by two or more symptoms, at least one of which should be either nasal blockage (congestion) or nasal discharge:

  • Nasal obstruction and congestion or nasal discharge (anterior or posterior)
  • With or without facial pain or pressure
  • With or without reduction or loss of smell
  • Endoscopic signs of nasal polyps or evidence of nasal polyps on computed tomography
