Let's return to the patient who was
0:03
hit in the face with a bag of bricks,
0:06
was assaulted with a bag of bricks and
0:08
had multiple fractures. So again,
0:10
we're going to focus for the purposes of this segment
0:13
just on the nasal bones.
0:15
So as we come up superiorly,
0:17
we come into the nasal bones and we notice that there are
0:20
fractures involving the nasal bones that are comminuted
0:25
and offset slightly bilaterally. This one a little bit inward,
0:28
this one a little bit outward,
0:30
and you can see that there's multiple pieces of the bone
0:35
even as it comes up to the frontonasal suture.
0:38
I want to just, again,
0:40
point out the importance of making attention,
0:44
pointing attention to the nasal septum
0:46
because as you can see here,
0:47
the patient has a fracture of the nasal septum which is
0:51
displaced, and the fracture fragment is obliquely oriented.
0:57
The nasal septum is actually a three part structure.
1:00
It includes the perpendicular plate of the ethmoid bone,
1:04
which is seen here, and which, as you can see,
1:08
is fractured at its superior portion.
1:11
So this is the perpendicular plate of the ethmoid bone and
1:14
it comes and communicates with the ethmoid sinuses.
1:18
The inferiormost portion is something called the vomer,
1:22
and the vomer is a bony portion of the nasal septum.
1:27
But far anteriorly,
1:29
what we have is the cartilaginous portion of the
1:32
nasal septum. The cartilaginous portion, again, as I mentioned,
1:35
because it's not bony, you can have fractures of the cartilage.
1:39
It's just we don't see it very well on CT scanning
1:42
and it's more of a clinical diagnosis.
1:44
So here we have an example of a patient who has, down here,
1:49
a fracture of the vomer. And more superiorly,
1:52
a fracture of the perpendicular plate of the ethmoid bone.
1:56
Two portions of the nasal septum.
