zygomaticofrontal

The zygomaticofrontal is an anatomical term most often used to describe the suture that joins the frontal bone to the zygomatic bone on each side of the skull. This sutural line runs obliquely from the superolateral orbital margin toward the lateral aspect of the frontal bone, forming part of the lateral margin of the brow region. It is one of several craniofacial sutures that permit limited movement of the bones during growth and provide attachment sites for surrounding soft tissues.

During embryonic development the frontal and zygomatic bones arise from mesenchymal condensations that ossify by intramembranous ossification. The zygomaticofrontal suture appears as a distinct, serrated junction in early childhood and gradually becomes less conspicuous with age, though it often remains visible on radiographic imaging. The suture may be involved in craniofacial trauma; fractures that cross the zygomaticofrontal area can affect orbital integrity and may require surgical reduction.

Clinically, the suture serves as a landmark for surgeons performing procedures such as brow lifts, orbital floor reconstruction, and placement of fixation devices in facial reconstruction. Anatomical variations are uncommon, but in some individuals the suture may be interconnected with accessory sutures or ossified bridges, which can influence both imaging interpretation and surgical approach.
