An ENT doctor will diagnose acute sinusitis based on your symptoms, medical history, and a simple physical examination. The doctor will ask about your symptoms and how long they last, look into your ears, nose, and throat, and may tap or press on your face to test for tenderness over specific sinuses.
After the diagnosis, if the sinus causes severe issues, surgery may be recommended. The modern and most advanced treatment is minimally invasive where sinus air cells are opened under direct visualization. The surgeons use a small camera called an endoscope allowing the surgeons to complete the procedure using detailed image guidance. FESS is a minimally invasive technique where the complete procedure is performed using detailed image guidance.
