The nasal wall of the maxillary sinus, or base, presents, in the disarticulated bone, a large, irregular aperture that communicates with the nasal cavity. [citation needed] In the articulated skull this aperture is much reduced in size by the following bones: …

2023年10月30日 · The maxillary sinus is the largest paranasal sinus situated in the body of the maxilla. The maxillary sinus is connected with the middle nasal meatus via the maxillary ostium. The maxillary sinus is bordered by three main walls: The floor – is composed by the alveolar process of the maxilla.

2025年1月18日 · The maxillary sinus has four walls: Anterior wall : This wall is adjacent to the cheekbone and the alveolar process, which holds the upper teeth . The anterior wall is also in close proximity to the infraorbital nerve and the infraorbital …

2025年1月14日 · The maxillary sinus (or antrum of Highmore) is a paired pyramid-shaped paranasal sinus within the maxillary bone which drains via the maxillary ostium into the infundibulum, then through hiatus semilunaris into the middle meatus. It is the largest of the paranasal sinuses.

Superior: frontal sinus, sphenoid sinus, anterior cranial fossa; Inferior: palate, oral cavity; Medial: other half of nasal cavity; Lateral: maxillary sinus, ethmoid sinuses, orbit, and pterygopalatine fossa; The lateral wall of the nasal cavity is of great significance in …

There are six maxillary sinus walls: the superior, anterior, lateral and medial walls are broad, with narrow posterior and inferior walls. Superior: the thin superior wall (forming most of the orbital floor), separates the contents of the orbit from the maxillary sinus.

2022年9月12日 · It has a central location and provides structural support to the viscerocranium. It has functional and aesthetic significance as it has a fundamental role in facial architecture, separates the nasal and oral cavities, forms the upper jaw, and contains the maxillary sinus (See Image. Maxillae). [1] [2]

2023年2月11日 · The medial wall separates the maxillary sinus from the nasal cavity. Still, they communicate throughout the ostium, located in the medial wall inferior or at the same level of the orbit floor. The inferior wall, known as the sinus floor, is closely related to the posterior teeth apices, from which it is separated only by a layer of compact bone.

The maxillary sinus (Sinus maxillaris; Antrum of Highmore), the largest of the accessory sinuses of the nose, is a pyramidal cavity in the body of the maxilla. Its base is formed by the lateral wall of the nasal cavity, and its apex extends into the zygomatic process.

2024年8月13日 · It is the largest of the paranasal sinuses, and the first to develop. The maxillary sinus is bound by broad superior, lateral, and anterior walls, and narrow inferior and posterior walls. The sinus walls correspond to the orbital, alveolar, …
