Different surgical approaches are available for reduction and fixation of orbital floor fractures. However, each approach could be associated with eyelid retraction and ectropion and/or scar visibility. In this study, intra-oral approach could be alternative approach for reduction and fixation of orbital floor fracture with avoidance of the aforementioned problems.
Materials and methods : 20 patients were complaining of displaced orbital bone fracture (including; frontozygomatic suture and orbital floor). Lateral eye brow incision was used for fixation of frontozygomatic suture. However,the orbital floor was reached through intra-oral incision. The mucosal tissues were dissected and elevated upwards till reach the inferior orbital rim. Infra-orbital nerve was dissected and isolated for easy and a traumatic retraction during reduction and fixation of fractured segments. Then the fractured segments were reduced and fixed using titanium plates and screws.
Results :19 patients were treated by both lateral eye brow and intra-oral incisions for bone fixation using titanium plates and screws. However, one patient needed additional lower lid incision for making sure that the floor is perfectly reduced with no muscle entrapment. No lower lid ectropion and/or scar appearance.
Discussion : Intra-oral approach is a good approach for reduction and fixation of orbital floor fracture unless; there are no comminuting floor and/or muscle entrapment.
