Hello everyone, Sidney Levy here rounding out
0:03
our discussion on the anatomy of the oropharynx.
0:07
In particular, I'd like to look at the
0:09
posterior oropharyngeal wall briefly.
0:12
I have axial and sagittal
0:14
projections with T1-weighted imaging.
0:17
And I'd just like to draw the
0:19
posterior oropharyngeal wall for you.
0:22
So where does it begin?
0:24
On the sagittal projection it's easy because
0:27
where it begins is where the nasopharynx ends
0:31
superiorly, and where it ends is where the posterior
0:35
hypopharyngeal wall begins as part of the hypopharynx.
0:40
These are indirect relations because we
0:43
tend to define the level of the posterior
0:45
wall according to anterior structures.
0:48
So what I mean by that is the junction of the posterior
0:51
oropharyngeal wall and the nasopharynx is at the
0:55
level of the pharyngeal isthmus, which is a line
0:58
drawn between the tip of the uvula of the soft palate
1:02
and the posterior pharyngeal wall at that level.
1:05
Similarly, inferiorly, the posterior oropharyngeal wall
1:09
ends at the level of the junction of the lingual and
1:14
laryngeal surfaces of the epiglottis, which is here.
1:19
And we just draw a line to the
1:20
posterior pharyngeal wall at this level.
1:23
And that is the junction of the posterior oropharyngeal
1:27
wall and the posterior hypopharyngeal wall.
1:30
The relationships of the posterior oropharyngeal wall
1:36
laterally are best appreciated on the axial projection.
1:39
So on the axial projection, anterolateral to the posterior
1:43
oropharyngeal wall, which I'll draw here, we have the
1:48
tonsils, or more specifically, the palatine tonsils.
1:52
You can look for the exact junction if you can identify
1:55
the posterior tonsillar pillar, which is just here.
1:59
It connects the soft palate to
2:02
the lateral oropharyngeal wall.
2:04
So in summary, the posterior oropharyngeal wall is
2:09
defined according to the level of the pharyngeal isthmus
2:13
superiorly and the site at which the junction of the
2:19
lingual and laryngeal surfaces of the epiglottis is.
2:24
And its relationships are the nasopharynx
2:27
superiorly, hypopharynx inferiorly, and
2:33
the palatine tonsils anterolaterally.
