There are four different types of sinusitis: acute, subacute, chronic and recurrent.

Causes of sinusitis include the common cold, a deviated septum, smoking, medications that suppress the immune system, chemical irritation, nasal polyps and allergic rhinitis.

Sinusitis symptoms include runny or stuffy nose, green nasal discharge, fever, facial tenderness or headache and cough.

Sinusitis treatment depends on the type and severity of the sinus infection. If you have bacterial sinusitis, your physician will usually prescribe antibiotics. In many cases, your physician will recommend you use a decongestant, saline nasal washes and over-the-counter (OTC) medications.

Sinus surgery is reserved for patients who have failed maximum medical management. Currently the gold standard for treating sinuses is computer-assisted sinus surgery - called functional sinus surgery or functional endoscopic sinus surgery.
