Orbital blow-in fractures occur when there's is displacement of bone fragments towards the orbits.

Pathology

  • blow-in fracture effectively reduces the volume of the orbit
  • associated intraorbital injuries include extraocular muscle entrapment and optic nerve injury
  • as an isolated (pure) orbital roof fracture is rare. These type of fractures are usually impure which means they usually occur in conjunction with other facial bone fractures such as supraorbital rim and frontal sinus fractures
  • it is important to assess for intracranial injuries including contusions, intracranial hemorrhage/hematoma 

Imaging

  • CT is the modality of choice for diagnosis and choice of appropriate (surgical or conservative) treatment for orbital blow in fractures
  • Sagittal and coronal projections are the optimal projections for assessment of orbital blow in fractures

Treatment

Surgical orbital decompression when fractures are associated with significant bone displacement.
