2023年9月14日 · Zygomaticomaxillary complex (ZMC) fractures, also known as tripod, tetrapod, quadripod, malar or trimalar fractures, are seen in the setting of traumatic injury to the face. They comprise fractures of the: zygomatic arch. inferior orbital rim, and anterior and posterior maxillary sinus walls. lateral orbital rim

2016年6月30日 · There is a comminuted, inferiorly displaced fracture through the right orbital floor (curved arrow) involving the infraorbital nerve canal, and a minimally displaced fracture of the lateral wall of the right maxillary sinus (wavy arrow).

3-D reconstruction of a right zygomatic complex fracture. For zygomatic complex and orbital floor fractures, preoperative CT scans in axial and coronal slices are standard.

CTscan 3D reconstruction images of classical ZMC fracture lines showing the anteromedial (AM) line (red arrow), superolateral (SL) line (yellow arrow), inferior (I) line (green arrow), and zygomatic arch (ZA) line (blue arrow).

The zygomaticomaxillary complex (ZMC) plays a key role in the structure, function, and esthetic appearance of the facial skeleton. A ZMC fracture is also known as a tripod, tetrapod or quadripod fracture, trimalar fracture or malar fracture.

2023年4月7日 · ZMC fracture assessment on CT should focus on confirmation of the injury pattern while describing any displacement and/or rotation of the zygomatic body because the most important surgical goal is the preservation of normal orbital volumes. 11, 14

In the present study, we present a novel method of ZMC fracture assessment, which utilizes a three-dimensional imaging modality to visualize and quantify malar eminence displacement in the anterior-posterior, medial-lateral, and superior-inferior dimensions.

2024年2月29日 · Computed tomography (CT) scans are considered the criterion standard for radiologic diagnosis of ZMC fractures. [5, 6] Other tests include those for visual acuity, extraocular motion, and...

ZMC fractures may present as an isolated injury or in combination with multilevel facial fractures. The zygoma determines the facial width and projection and greatly impacts the orbital volume through its contribution to the lateral orbital wall and the orbital floor.

Here’s a #tweetorial to help you understand fractures of the zygomaticomaxillary complex or ZMC 2/ ZMC is the malar eminence (cheekbone) & its midface/skullbase attachments. Today we think its purpose is aesthetics (our model cheekbones).
