i understand your concern Your Xray report suggests that there is mild thickening of the mucosal lining of both maxillary sinuses, this indicates that you are suffering from low grade maxillary sinusitis. Mild deviation of the nasal septum to the right might as well contribute to the delayed drainage of maxillary sinus. Maxillary sinus is one of the four paranasal sinuses. The Maxillary sinus is the largest of the paranasal sinuses. The two maxillary sinuses are located below the cheeks, above the teeth and on the sides of the nose. The maxillary sinuses are shaped like a pyramid. The sinuses are tiny air-filled holes found in the bones of the face which reduce skull weight, produce mucus, and affect the tone quality of a person s voice. The maxillary sinus drains into the nose through a hole called the ostia. When the ostia becomes clogged sinusitis can occur. The ostia of the maxillary sinus often clog because the ostia are located near the top of the maxillary sinus causing drainage to be difficult. Sinusitis is the most common of maxillary sinus illnesses and is usually treated with prescription antibiotics. Take Care!
