Diagnosis and complications of late treated Zygomatic complex fractures – Case series

Abstract

Zygomatic complex is the term used for Zygomatic bone, parts of maxilla, frontal bone, temporal bone and sphenoid bone. It forms the infrastructure of anterolateral part of the face and prominence of cheek.[1] Majority of zygomatic complex fracture occur due to road traffic accidents, other causes include fall, sports injury and assaults.[2] It transmits the occlusal stress to the base of skull along its vertical and horizontal struts. In majority of the cases of zygomatic complex fractures, the fractured part displaces inward. In cases of inwardly displaced zygomatic complex fractures trismus, epistaxis and diplopia are commom finding. [3] Subconjunctival haemorrhage is also one of the common features of the zygomatic complex fracture. Subconjunctival haemorrhage has no posterior limit and remains bright red owing to the ability of oxygen to diffuse through the conjunctiva to the collection of blood. This article presents a case series of management of malunited Zygomatic fractures at our centre.
