Paranasal Sinuses and Sinus Infections

by Lee on December 14, 2010

Sinuses are air spaces in the facial bones. These hollow spaces make your facial bones lighter. There are four pairs of sinuses surrounding your nasal cavity. The frontal sinuses are cavities in the forehead area above your eyes. The sinuses located between the eyes behind the bridge of the nose are called ethmoid sinuses. Behind the ethmoid sinuses are the deeper hollow spaces called the sphenoid sinuses, which only develop during puberty. The maxillary sinuses are found in the cheeks above the upper jaw in both sides of the nostrils.

The paranasal sinuses serve various purposes. One is to make your facial bones lighter. In speech and singing, these cavities act as resonating chambers. The air spaces also act like shock absorbers in case you get blow to the face. These cavities also warm and moisten air upon entry into the nasal cavity.

A narrow passage links the paranasal sinuses to the nasal cavity. These tiny openings are called ostia, which be easily blocked during colds. Blockage of these tiny openings leads to accumulation of mucus in the sinus cavities. Bacteria may proliferate within the blocked cavities and inflammation follows, and what happens is you get sinusitis. Sinus infections can cause headaches and facial pain, nasal congestion, sore throat, cough, sneezing, and fever.

Bacterial sinusitis may be treated using antibiotics, while viral sinusitis may be treated using antiviral medications. Decongestants and mucolytics may facilitate drainage and expulsion of mucus. Prompt treatment of sinus infections is necessary because various complications can develop. Some tinnitus treatment remedies are geared to treating existing sinus infection. However, tinnitus is just one of the less serious complications of a sinus infection.
