zygomaticomaxillary complex
Also written as: ZMC — zygomaticomaxillary complex
Anatomical region encompassing the cheekbone and its connections to surrounding facial bones.
Full Definition
The zygomaticomaxillary complex (ZMC) refers to the anatomical unit consisting of the zygomatic bone and its articulations with the maxilla, frontal bone, temporal bone, and sphenoid bone. This complex forms the prominence of the cheek and contributes significantly to facial width and contour. ZMC fractures are among the most common facial fractures, often resulting from blunt trauma. Surgical repair typically involves reduction and fixation through multiple approaches, with attention to restoring facial projection, orbital volume, and preventing complications such as enophthalmos or infraorbital nerve dysfunction.
Usage
Usage note: ZMC is the preferred abbreviation in clinical documentation.
