Adipose tissue, inferior rectus or inferior oblique can entrap within maxillary or ethmoid sinus. Patient consent Guardian consent obtained.Įthics approval Approvals from Ethics Committee of Shanghai Ninth People’s Hospital were obtained. Fracture of inferior or medial orbital walls with out fracture of orbital ridge. Treatment depends on how severe your entrapment. You can have a fracture in one or all of these parts of the eye socket: The inferior wall, or orbital floor, is formed by the upper jawbone (maxilla), part of the cheek bone (zygomatic), and a. Understanding the classification scheme described by Rene Le Fort in 1991 is useful in evaluating ZMC fractures because Le Fort II and III fractures both have a ZMC fracture component. This usually causes swelling and pain, and often affects ( impairs) vision. indicates Zingg fracture types in which the orbital contents are at risk. An orbital floor fracture with entrapment is a break in the orbital floor that allows nearby muscle, tissue, or both to get trapped inside of the fracture.

An injury such as an orbital fracture can involve many of the same structures that affect your face, mouth, and jaw. When you are faced with complex or compounded facial injuries, you’ll be thankful for the talent and experience of an oral surgeon. Fractures of the orbit may be seen in different scenarios of direct and indirect trauma to the globe, orbital, facial, or cranial bones. The orbit is formed by 7 bones: zygomatic, sphenoid, maxillary, frontal, lacrimal, palatine, and ethmoid. The most common symptoms are bruising, tenderness and swelling around the eye redness of the eye. The orbit is one of a pair of bony cavities each housing the globe and associated structures.
