The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark. [1] The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxillary suture. It is placed at the level of the nostrils, at the uppermost part of the philtrum.
The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus labii superioris, the orbicularis oculi, and the medial ...
Maxillary hiatus. Medial wall of left orbit. Left maxilla. Nasal surface. The maxillary hiatus (also known as maxillary sinus ostium, maxillary ostium, or opening from the maxillary sinus) [citation needed] is the opening of a maxillary sinus into the middle nasal meatus of the nasal cavity. It is situated superoposteriorly upon the lateral ...
Left maxilla, medial view. Maxillary sinus entry shown in red. The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [1][2] through the semilunar hiatus. It is located to the side of the nasal cavity, and below the orbit.
Panoramic radiograph. A dental panoramic radiograph, showing the maxilla and mandible, all the teeth including the " wisdom teeth," the frontal and maxillary sinuses, the nasal cavity and the temporomandibular joint and other near by head and neck anatomy. A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.
Radiology. [edit on Wikidata] Waters' view (also known as the occipitomental view or parietoacanthial projection) is a radiographic view of the skull. It is commonly used to get a better view of the maxillary sinuses. An x-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the ...
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
From the lower border of the inferior nasal concha, a thin lamina, the maxillary process, curves downward and laterally; it articulates with the maxilla and forms a part of the medial wall of the maxillary sinus.
