A maxillary sinuscyst is an abnormal tissue growth located in either of the cavities located behind the cheekbones on either side of the nose. These cavities are called sinuses, and they are located in the maxilla, or upper jaw. Cysts are closed, pocket-like formations of tissue and are filled with liquid, air or semi-solid material. Most cysts are completely harmless and require treatment only if they grow large enough that they interfere with the functions of surrounding tissues.
Sinuses
The maxillary sinuses are one of three types of sinuses that are associated with — and open into — the nasal passages. The cavities behind the nose and eyes are the ethmoid sinuses. Those behind the forehead area are the bilateral sinuses.
Cysts
PANO AQIL: Authorities registered Monday night a recent case of Karo-kari — or honour killing — that left two people dead here in the town's Shahbazi Bullo village, Geo News reported.
Cysts can form anywhere on the body and can be caused by infections, inflammatory reactions, blockage of the normal movement of fluid or genetic disorders. Cysts that are on or near the surface of the skin or in soft tissue such as the breast might be noticed by the patient first. Those that lie deeper inside the body, such as those in the maxillary sinuses, might not be found until they cause enough irritation that diagnostic testing must be done.
