What is Zygoma?

The zygoma, also known as the zygomatic bone or cheekbone, is a paired, irregular bone forming the prominent part of the cheek and contributing to the structure of the eye socket (orbit). It plays a crucial role in facial structure and protection.

• Location: The zygoma is situated at the upper and lateral part of the face. [Wikipedia]
• Structure: It's a key component of the zygomatic complex, contributing to the anterior and lateral portions of the face. [StatPearls, Reference 1] This complex protects the orbit's contents and shapes the cheeks. [Reference 1] The zygoma articulates (joins) with other facial bones, creating a strong framework. [Wikipedia]
• Function: The zygoma provides structural support to the midface, acting as a crucial intersection of facial buttresses. [ScienceDirect] Its strong structure helps protect the eye and underlying tissues. [StatPearls]

Clinical Significance

The zygoma's importance extends beyond its structural role. It's frequently involved in:

• Facial Fractures: Due to its prominent position, the zygoma is susceptible to fractures from trauma. [DocDoc]
• Surgical Procedures: Zygoma reduction (trimming and reshaping) and zygomatic implants (replacing missing bone) are surgical procedures addressing aesthetic or reconstructive needs. [DocDoc, Celal Candirli]

Zygoma vs. Zygomatic Arch

While often used interchangeably, it's important to distinguish between the zygoma (the bone itself) and the zygomatic arch. The zygomatic arch is a bony structure formed primarily by parts of the zygomatic bone and the temporal bone. [Wikipedia, Merriam-Webster]
