If symptoms persist despite adequate therapy, a referral to an otolaryngologist (ENT) may be necessary.
Adequately distinguishing sinusitis from a simple upper respiratory infection or a common cold is important.
The sinuses are covered with a mucous layer and cells that contain tiny hairs on their surface (cilia).
These help trap and propel bacteria and pollutants outward.
Medications that are designed to modify the immunse system may also increase the risk of developing a sinus infection.
Sinusitis is often first diagnosed by a general practitioner, primary care physician, or internal medicine physician. If sinusitis is chronic or severe, you may be referred to an otolaryngologist, also called an ear, nose, and throat specialist (ENT).
