Chronic Rhinosinusitis Specialty Group Overview Print Mayo Clinic allergists diagnose and treat chronic rhinosinusitis, one of the most-reported chronic diseases in the United States. An allergy specialist gathers a comprehensive history and performs a physical examination. Your condition may require a rhinoscopy, which is a visualization of the nasal passageways, sinuses and upper airway with a fiber-optic scope. Allergy testing may also be added to determine whether an allergen is contributing to the sinusitis. You may also consult with Otorhinolaryngologists (Ear, Nose and Throat specialists).
