INTRODUCTION:

Structures Anatomical of the Maxillary Sinus

The largest paranasal sinus, the pyramid-shaped maxillary sinus (also known as the antrum of Highmore), is situated in the maxilla. Through the semilunar hiatus, it empties into the middle meatus of the nose [1]. It is situated inside the maxilla's body, but when it gets big, it may extend into the zygomatic and alveolar processes. It is situated to the side of the nasal cavity and below the orbit. It has a pyramidal form, with the lateral nasal wall serving as the base and the maxillary zygomatic process as the apex. [3]

It has three recesses: an inferiorly orientated alveolar recess bounded by the maxilla's alveolar process; a laterally orientated zygomatic recess bounded by the zygomatic bone; and an inferiorly orientated infraorbital recess bounded by the maxilla's inferior orbital surface. Cartilage makes up the majority of the medial wall.[2] [Fig:1]
