The palatine bone is located on the face of the skull, approximately between the nasal cavity and the oral cavity, behind the maxilla, and belongs to the facial cranial bones, which participate in the composition of the oral and nasal cavities. The palatine bone belongs to the facial cranial bones, roughly behind the nasal cavity and superiorly behind the oral cavity. The palatine bones are adjacent to the maxilla and platysma anteriorly, to the inner and outer lateral plates of the pterygoid pterygoid process posteriorly, to the nasal cavity internally superiorly, and to the oral cavity externally inferiorly. The palatine bone has two left and right paired pieces, which are “L” shaped and divided into two parts: the horizontal plate and the vertical plate. The horizontal plate constitutes the posterior 1/4 of the oral hard palate, the lateral edge of the horizontal plate is involved in the formation of the palatal foramen magnum, and the horizontal plates on both sides converge in the palatal median suture to form the postnasal spine and the plow bone. Its vertical plate forms the posterior lateral wall of the nasal cavity, and its superior edge joins the pterygoid and orbital processes. The palatine bone is an important facial and cranial bone that constitutes the hard palate and nasal cavity, as well as connecting the pterygoid bone and maxilla, etc. It has important anatomical significance.
