We're dedicated to providing diagnosis and treatment Acute sinusitis is usually treated with medications or flushing before sinus surgery is considered. The ENT physician may find that the recurrent infections are not as responsive to treatments after some time. In these cases, surgery to enlarge the nasal passageways and drain the sinuses is considered. Before sinus surgery options are considered, the ENT physician will first ask a series of questions about clinical history. Then, a diagnostic workup will be undertaken to determine the underlying cause of the sinusitis before considering sinus surgery. Some tests include CT imaging, nasal physiology, smell testing, and blood analysis. We currently use FESS in sinus surgery. This includes functional endoscopic sinus surgery and image-guided surgery.
