Explain The Anatomy Of The Maxillary Sinus
Anatomy of the maxillary sinus: The maxilla consists of a variety of anatomic structures, including the maxillary sinus, the lateral nasal walls, the pterygoid plates, associated vasculature structures, and teeth. The maxillary sinus is pyramidal in shape. The base of the pyramid is the medial wall of the sinus that is also the lateral wall of the nasal cavity, and its apex is pointed towards the zygomatic bone. The roof of the sinus is also the floor of the orbit. The sinus has a non-physiologic drainage port high on the medial wall (maxillary ostium) that opens into the nasal cavity between the middle and lower nasal conchae. The maxillary sinus maintains its overall size while the posterior teeth remain in function. It is,
