Nasal Bone Anatomical Structure

Description

Centered on the midline of the anterior skull, the paired nasal bones are highlighted and sit inferior to the frontal bone at the nasion, where the frontonasal suture meets the internasal suture. Laterally, each nasal bone articulates with the frontal process of the maxilla, forming the medial margin of the piriform aperture, while the bony orbits lie superolateral with the zygomatic bones contributing to the cheek prominence. Inferiorly, the maxilla supports the upper dentition and frames the nasal cavity, with the mandible and its teeth visible below in anatomical position. Clear cranial sutures outline the frontal and parietal bones, and the upper cervical vertebrae appear inferior to the occipital region. Anterior emphasis on the nasal bridge matters because the nasal bones are the most commonly fractured facial bones, and displacement at the nasion or along the frontomaxillary region can accompany septal hematoma, airway compromise, or more complex naso-orbito-ethmoid injuries. Alignment at the midline. This perspective also supports preoperative planning for rhinoplasty and dorsal augmentation, where the relationship between the nasal bones, the frontal process of the maxilla, and the piriform aperture guides osteotomy placement and helps avoid destabilizing the medial canthal attachments near the lacrimal fossa. Use this artwork for head and neck anatomy teaching in medical, dental, and PA curricula when introducing the facial skeleton, cranial sutures, and bony landmarks used on physical exam and trauma documentation. It also fits facial trauma chapters, ENT and maxillofacial surgery atlases, and patient-facing educational materials explaining nasal fracture reduction and postoperative bony healing.
