Maxillary antrum is also known as maxillary sinus and is the biggest of the paranasal sinuses. Mucosal thickening within the maxillary antrum is one of the signs of sinusitis.
Mucosal thickening in the sinus cavity is commonly called sinusitis. It is most often caused by a viral infection and is treated with antibiotics.
Inflammatory thickening of the antral mucosa is sometimes a symptom of nasopharyngeal carcinoma. Usually, it is an immunologic response to an irritant in the passages.
Polypoidal mucosal thickening in the bilateral maxillary sinus refers to a condition causing polypoid masses and swelling in the nasal cavities. These masses or tumors are generally non-malignant, but need to be treated by a physician.
It means there is fluid in that sinus. You have a right & a left maxillary sinus. Sometimes one can be worse than the other or only one can be infected.
This medical phrase means that you have a chronic sinus infection. Your maxillary paranasal air sinuses are inflamed and narrowed which is what is making it difficult to breathe and clear the nose of mucus.
Mild mucosal thickening along the left frontal sinus is a sign of sinusitis.
Sinus
The maxillary sinuses are one of 4 sets of air filled sinuses in the face. The right maxillary sinus sits to the right of your nose. Sinuses are lined with mucosal tissue and a polyp is mucosa that has overgrown into a ball like shape.
Mucoperiosteal reaction = sinus wall thickening. Typically this is secondary to chronic sinus opacification (Chronic rhionosinusitis).
paranasal sinus include frontal sinus, the maxillary sinus, the ethmodial sinuses, and the spheniodal sinus.
