MAXILLARY ANTRUM Meaning and
Definition
-
The maxillary antrum, also known as the maxillary sinus or maxillary air sinus, is a hollow cavity found within the maxilla, which is the largest facial bone located in the upper jaw. It is one of a pair of sinuses, with the other being the frontal sinus, found in the forehead.
The maxillary antrum is lined by a mucous membrane and is filled with air. It is a pyramid-shaped cavity that is situated below the eyes and above the upper teeth. This sinus is highly variable in shape and size among individuals, but on average, it measures approximately 3 cm in height, 2 cm in width, and 3 cm in depth.
The main functions of the maxillary antrum are to reduce the weight of the skull, enhance voice resonance, and provide protection to the delicate structures of the upper jaw. Additionally, it serves as a buffer against facial trauma by absorbing and dispersing forces directed towards the front of the skull.
The maxillary antrum is also prone to certain conditions and diseases, such as sinusitis, which is an inflammation or infection of the sinus lining. This can cause symptoms like facial pain or pressure, congestion, postnasal drip, and headaches. In severe cases, surgical intervention may be required to drain the sinus and alleviate symptoms.
