Abstract:
Nasal polyps are found in 36% of patients with aspirin intolerance, 7% of those with asthma, 0.1% in children, and about 20% in those with cystic fibrosis. Other conditions associated with nasal polyps are Churg-Strauss Syndrome, allergic fungal sinusitis, and cilia dyskinetic syndrome, (Kartagener's) and Young Syndrome. Nasal polyps are statistically more common in nonallergic asthma versus allergic asthma (13% vs 5%, P < 0.01). About 40% of patients with surgical polypectomies have recurrences. There appears to be a hereditary factor for developing nasal polyps. A classification system for staging nasal polyps is proposed in order to standardize treatment, consider differential diagnosis, and harvest meaningful comparative research information.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
