Brief Summary:
Aim of this study is to assess the efficacy of endoscopic trans-maxillary surgical approach versus traditional trans-orbital surgical approach (control group) in orbital blow out fractures in terms of postoperative clinical and digital radio-graphical assessments.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: endoscopic trans-antral approach
The maxillary sinus and prolapsed orbital contents will be visualized employing a 30-degree endoscope for the repair of orbital blow out fracture (sinus scope 4 mm, 30 degrees short one 17 cm).
Procedure: endoscopic trans-antral approach
new surgical approach to repair the orbital floor fractures through the maxillary sinus
Other Name: trans-maxillary

Active Comparator: trans-orbital surgical approach
trans-orbital surgical approach through the lower eyelid Sub-ciliary incision ( through the lower eyelid) The skin incision is made just below the eyelashes.
Procedure: trans-orbital surgical approach
through the lower eyelid below the eyelashes ,then down to bone the herniated orbital content will be reduced through this incision traditional surgical approach to repair orbital floor fractures
Other Names:
  • sub-ciliary incision
  • lower eyelid incision
  • skin incision
