[Fractures of the zygomatic bone]

Area of Science:

• Oral and Maxillofacial Surgery
• Trauma Surgery
• Medical Imaging

Background:

• Fractures of the upper and middle facial zones are common, frequently involving the zygomatic bone.
• Injuries to the zygomatic bone and maxillary sinus walls often occur concurrently.
• Accurate diagnosis is crucial for effective treatment planning in facial trauma.

Purpose of the Study:

• To investigate the characteristics of zygomatic bone fractures in conjunction with maxillary sinus injuries.
• To establish a rational classification system for zygomatic bone fractures.
• To evaluate the efficacy of panorama zonography in diagnosing these fractures.

Main Methods:

• Retrospective analysis of 248 patients with upper and middle facial zone fractures.
• Clinical examination focusing on zygomatic bone and maxillary sinus integrity.
• Diagnostic imaging using panorama zonography.

Main Results:

• A joint injury pattern was observed between the zygomatic bone and maxillary sinus walls in a significant number of patients.
• Fractures were rationally grouped into isolated zygomatic bone process/orbital floor fractures and zygomatic-maxillary complex fractures.
• Panorama zonography demonstrated high effectiveness in diagnosing zygomatic bone and zygomatic-maxillary complex fractures.

Conclusions:

• Concurrent injury of the zygomatic bone and maxillary sinus is a common presentation in facial trauma.
• A proposed classification aids in understanding fracture patterns.
• Panorama zonography is a valuable diagnostic tool for zygomatic bone and complex facial fractures.
