Zygomaticomaxillary complex (ZMC) fractures often injure the infraorbital nerve, causing facial numbness. This review covers the anatomy, diagnosis, treatment, and prognosis of this common maxillofacial injury.
Area of Science:
- Maxillofacial Surgery
- Neurosurgery
- Anatomy
Background:
- Zygomaticomaxillary complex (ZMC) fractures are prevalent maxillofacial injuries.
- These fractures frequently involve the infraorbital nerve, leading to sensory deficits.
Purpose of the Study:
- To comprehensively review the anatomy, diagnosis, assessment, treatment, and prognosis of infraorbital nerve injuries associated with ZMC fractures.
Main Methods:
- Literature review of anatomical studies, diagnostic modalities, and surgical/non-surgical treatments for ZMC fractures and associated nerve injuries.
Main Results:
- Infraorbital nerve injury presents with paresthesia in the lower eyelid, malar, nasal, and upper lip regions.
- Accurate diagnosis relies on clinical examination and imaging.
- Treatment strategies vary based on fracture severity and nerve involvement.
Conclusions:
- Understanding the infraorbital nerve's anatomy is crucial for managing ZMC fractures.
- Timely diagnosis and appropriate treatment can improve outcomes for patients with ZMC fracture-related nerve injuries.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
