Transantral endoscopic repair of orbital floor fractures with the use of a flexible endoscope holder: a cadaver study.

We conducted a cadaver study to determine the ease of use and functionality of a flexible endoscope holder in the visualization and repair of orbital floor fractures via a transantral approach. Four fresh cadaver heads were dissected through a sublabial antrotomy incision with a 30 degrees endoscope attached to a flexible holder. An implant was placed to restore the normal anatomy. With the use of this exclusive endoscopic approach, all orbital floor fractures were identified in their entirety and completely reduced with alloplastic material. We conclude that the flexible endoscope holder provides clearer visualization, greater instrument mobility, and an overall superior dissection and placement of implants in the endoscopic repair of orbital floor fractures.
