Today, I would like to conclude our discussion
0:04
of the anatomy of the larynx by drawing and
0:08
discussing the boundaries of the subglottis.
0:11
So once again, I have our sample pre-contrast
0:15
T1-weighted imaging without fat suppression.
0:19
And I'll start by drawing the
0:21
superior boundary of the subglottis.
0:24
It's probably easiest to appreciate on
0:25
the coronal projection in this case.
0:28
Because we can see the vocal cords quite well.
0:31
So these are the true vocal cords.
0:33
These are the false cords.
0:35
And these are the laryngeal ventricles.
0:38
The boundary between the glottis and the subglottis
0:40
is the inferior margin of the true vocal cords, here.
0:46
So that's the superior margin of the subglottis.
0:51
The inferior margin of the subglottis is the
0:55
inferior margin of the larynx, which is the
0:57
inferior border of the cricoid cartilage.
1:01
So everything in this region is subglottis.
1:05
Everything at the level of the true vocal
1:08
cords is glottis, over about one centimeter.
1:13
And everything above the laryngeal ventricles,
1:16
including the false cords, is the supraglottis.
1:21
On the axial projection, the subglottis
1:24
is at the level of the cricoid cartilage.
1:26
So need to be familiar with the cricoid cartilage.
1:29
That's the coronal view of it.
1:31
This is the sagittal view of it.
1:37
And this is the axial view of it.
1:40
And everything anterior to that at
1:43
this level is subglottic larynx.
1:47
So in summary, the subglottis is the most inferior sub
1:50
side of the larynx, and its boundaries are superiorly
1:54
the inferior margin of the true vocal cords,
1:57
and inferiorly the inferior margin of the cricoid cartilage.
