title: [Clinical features and treatment of lateral orbital wall blow-in fracture].
abstract: OBJECTIVE
  To analyze the clinical features of lateral orbital wall blow-in fracture and summarize the points of treatment.
  
  
  METHODS
  A retrospective analysis of 12 patients with lateral orbital wall blow-in fracture treated in the Department of Ophthalmology, Shanghai Ninth People's Hospital, Shanghai Jiaotong University School of Medicine from January 2007 to January 2010 was investigated. Clinical records and results of follow-up were analyzed.
  
  
  RESULTS
  Twelve cases of the lateral orbital wall blow-in fracture with the frontal process of the zygoma impacted into the orbit were confirmed. Globe rupture occurred in 1 case, 4 cases had traumatic optic neuropathy. 1 case suffered exophthalmos, 8 cases had enophthalmos. Diplopia was found in 5 cases and eyeball movement disturbance in 5 cases.3 cases had upper eyelid deformity, 1 case had ptosis, 3 cases had telecanthus accompanied with lacrimal ducts obstruction. 11 cases suffered orbital floor fracture, 9 cases had zygomatic arc fracture, 6 cases had orbital medial wall fracture, and 3 cases had naso-orbito-ethmoid fracture. Surgical treatment was performed by different combination of approaches according to the extents of injury; Osteotomy was performed in patients whose blow-in fracture was malformation. Orbital reconstructive surgery was performed in 11 patients and fractures were completely restored.
  
  
  CONCLUSIONS
  The lateral orbital wall blow-in fracture could cause serious impairment to the ocular components, better outcomes could be achieved by timely and proper treatment with improving recognition of this type of fracture.
