This is a follow-up to a patient who
0:03
has had an orbital floor fracture.
0:06
The patient has had correction surgically of the orbital floor.
0:11
This is best evaluated in the coronal plane.
0:14
As we scroll the images,
0:17
we see the metallic mesh where the orbital
0:20
floor has been reconstructed.
0:23
I tend to be a little bit more generous with respect to
0:28
the location of the mesh and the natural location
0:31
of the orbital floor with the surgeons.
0:35
So, although this orbital floor is not in the exact
0:39
symmetrical location with the contralateral side,
0:43
it is laid nicely in the orbital floor and reconstructs
0:48
the curvature of the orbital floor.
0:51
You notice that this fracture,
0:53
as with the previous case,
0:55
has involved the infraorbital foramen.
0:58
Now, you may be a little bit concerned about the elevation
1:01
of the plate from the orbital floor as we go
1:06
further posterior. Let me demonstrate that.
1:10
So here is the posterior aspect of the repair
1:14
plate and here is the natural orbital floor.
1:17
And you notice that there is a small gap here.
1:20
Do not alienate your plastic surgeons or oculoplastic
1:24
surgeons with regard to this small deviation from the
1:27
normal course of the orbital floor when you
1:30
compare it with the contralateral side.
1:32
The main benefit of this repair is that the inferior
1:37
rectus muscle and orbital fat has been replaced back
1:41
into the orbit and is no longer herniating through the
1:45
gap in the orbital floor, and that there is near-anatomic
1:50
positioning of the plate in the area of the previous fracture.
