Patient Data

Age: 50
Gender: Male

XR facial bones

Modality: X-ray

Multiple facial fractures:

  • diastasis of the left frontozygomatic suture

Opacification of the left maxillary sinus. No mandibular fractures.

CT facial bones

Modality: CT

See CT head report for soft tissue findings.

No skull base fracture.

Multiple facial fractures:

  • two minimally displaced fractures of the left zygomatic arch
  • displaced fractures of the medial, anterior and lateral walls of the left maxillary sinus
  • displaced fractures of the medial, lateral and inferior orbital margins
  • multiple nasal bridge fractures
  • cribriform plate appears intact
Modality: CT

See facial bone CT for report on fractures.

Main finding is 27mm acute haematoma within the inferior left retro-orbital space extending into the left maxillary sinus causing superior, lateral and anterior displacement of the globe. The inferior rectus muscle is not clearly visualised. Optic nerve appears to be intact.

The left maxillary sinus is filled with blood.

No intra-cranial injury.

Soft tissue swelling with flecks of gas in the tissues.

Case Discussion

This patient had an emergency lateral canthotomy performed by the ophthalmogists to preserve vision in his left eye as there was concern about optic nerve compression. His fractures were managed by the maxillofacial surgeons.
