Sinusitis: Allergies, antibiotics, aspirin, asthma

Sinusitis is very common, so it is important to understand its pathophysiology, diagnosis, and medical and surgical treatments. In cases of chronic sinusitis, adjunctive therapies and evaluation by subspecialists may be warranted. Some special testing is needed to diagnose allergic fungal sinusitis. Most important is to understand that sinusitis is not a single entity but is associated with many comorbid conditions, notably asthma.
