Case Review - Orbital Appendage Pathology
6 topics, 19 min.
0:01
This is a second case after repair of orbital fractures.
0:05
In this case,
0:06
one sees that the patient has had bilateral fractures of the orbital
0:12
floor with their communication to the medial orbital wall.
0:17
Once again,
0:19
the approximation of the mesh to the orbital floor need not be exact.
0:26
Sometimes, one can see the fracture repair extend
0:31
upward along the medial orbital wall
0:34
if the fracture has extended along the lamina papyracea,
0:39
so these would be extending both to repair the orbital floor ,
0:44
as well as the medial orbital wall in a continuous fashion.
0:48
The main thing that you do want to see, with regard to the repair, is that
0:52
the mesh that's laid in crosses the plane of the fracture itself.
0:58
So, it goes across the entire extent of the fracture.
1:02
Complications of the repair include continuous herniation
1:07
of either fat or muscle through the orbital floor or medial orbital wall
1:14
or orbital hematoma.
1:16
Therefore, in addition to the bone windows,
1:18
it's important to continue to look at the soft
1:22
tissue windows and observe the absence of hemorrhage
1:26
in the retrobulbar compartment or intraconal space,
1:29
or extraconal space.
1:31
In this case, the repair is outstanding.
