Chronic Sinusitis vs Allergy: Why So Many Patients Receive the Wrong Diagnosis

Chronic sinusitis and allergies share overlapping symptoms, which leaves many patients misdiagnosed and stuck in cycles of antihistamines, decongestants, and steroids without lasting relief. In this episode of Vital Discourse, Dr. Ben Cilento and Dr. Lee Mandel explain how to distinguish persistent bacterial or structural sinus disease from allergic inflammation and why treatment depends on identifying airflow obstruction, duration, CT scan patterns, and response to medical therapy. They break down the 12-week definition of chronic sinusitis, why CT scans often under-call real disease, and how structural issues like deviated septums and narrowed sinus openings trap fluid and fuel infection. The doctors walk through allergy testing, immunotherapy, minimally-invasive sinus surgery, balloon dilation, and the real role of medications.
