To understand the mechanism of injury and also
0:05
the combination of fractures that may occur,
0:08
people have described the vertical and transverse
0:12
buttresses of the mid face. And these
0:15
are demonstrated in this diagram.
0:17
The two transverse buttresses are seen in the coloration here
0:23
as the squamosal temporal bone, which is, this is portion of
0:27
the squamosal temporal bone to the nasofrontal
0:31
junction, across the zygomatic arch.
0:34
So here you can see the zygomatic arch and then
0:37
we're going to the nasofrontal junction.
0:39
Remember, we had our frontonasal suture here and our frontal
0:43
maxillary sutures and frontonasal sutures here,
0:46
and this involves the inferior orbital rim.
0:49
So this is one of the transverse buttresses.
0:52
The second buttress goes from the hard palate across the
0:57
maxilla here, and these are the mid-face buttresses.
1:02
The mandible down here is not actually
1:04
considered portion of the mid-face.
1:08
In addition,
1:09
there are two vertical buttresses and we see these
1:12
here. Unfortunately, both of them are in this orange coloration.
1:16
So the first one is along the posterior maxillary molars,
1:20
it goes to the zygomaticmaxillary suture
1:25
and then it goes along the lateral orbital rim, and
1:29
these are fractures that occur often in concert.
1:33
This may extend to the zygomaticafrontal
1:36
suture which you see right here.
1:39
The second one is the one that is on either side of the midline
1:43
along the nasal cavity, and that goes from the anterior nasal spine
1:48
region across the maxilla to the nasofrontal junction,
1:53
and then from there, into the frontal bone.
1:55
This may affect the medial orbital wall.
1:58
So, fractures of this particular area here on either side of the
2:05
midline, are generally what we refer to as the naso
2:08
orbital ethmoidal fractures, or NOE fractures,
2:12
which is what we are going to describe next.
