Orbital fractures are one of the common types of craniomaxillofacial injuries and can occur alone or in combination with other fractures of the craniofacial area. The orbit plays a protective role for the eye, and orbital fractures can occur when the orbit or the bones around the orbit are struck by external forces. The orbital fracture mainly has the following manifestations: 1, orbital depression: the main cause of orbital depression is the increase of orbital cavity volume caused by the fracture or the combined herniation of orbital contents into the fracture window. 2. Diplopia (double vision): In fracture, the orbital contents, including the extraocular muscles, are displaced to the fracture window, resulting in limited eye movement and double vision. Injury to the oculomotor nerve can also cause diplopia. Numbness in the infraorbital region: orbital floor fractures often injure the infraorbital nerve, causing numbness in the skin of the innervated area and even numbness in the teeth of the corresponding area. 4. Petechial hemorrhage and swelling: Trauma causes periorbital subcutaneous and subconjunctival hemorrhage. In the early stage, intraorbital hemorrhage and edema often result in protrusion of the eyeball. In the late stage, with the absorption of the hemorrhage, the protrusion of the eye can gradually return to normal, or the eye can be sunken in. 5.Other: Combined with zygomatic arch fracture, mouth opening restriction may occur. Combined with skull injury or nasal bone fracture will show corresponding clinical manifestations. These times need to cooperate with related departments such as dentistry, ENT and brain surgery for treatment or surgery. Auxiliary examinations 1. Plain film: Wachsler film can show the orbital apex and orbital floor. Indirect signs of fracture, such as teardrop-like manifestations or air-fluid planes, can be observed through this film. Plain films do not show fractures in the orbital wall well and cannot localize foreign bodies. 2, CT: The combination of axial and coronal and 3D reconstructed CT images can clarify the specifics of orbital rim and orbital wall fractures and soft tissue injuries, select surgical indications, and guide the development of surgical plans. 3, MRI: MRI can be used to assess the soft tissue injury in orbital trauma.
