Hello everyone, Dr. Sidney Levy here.
0:02
3 00:00:04,390 --> 00:00:06,780 Today I would like to talk about the anatomy
0:06
of the sinonasal cavity or sinonasal region as
0:10
a prelude to a discussion of the diagnosis and
0:13
staging of sinonasal squamous cell malignancy.
0:18
So firstly, what are the boundaries and
0:20
relationships of the sinonasal cavity?
0:22
And I would like to draw these for you.
0:25
I have here an example case of a large
0:28
sinonasal squamous cell carcinoma on the right.
0:31
But I would actually like to concentrate
0:33
on the left-hand side in order to demonstrate
0:35
some normal anatomy to you so that we are better
0:38
oriented when we start addressing the tumor.
0:41
On the axial projection, we have a T2-weighted sequence.
0:44
I can show you the left nasal cavity with its mucosa
0:50
communicating with the maxillary sinus and its mucosa.
0:55
And the posterior boundary is the choana,
0:59
beyond which we have the nasopharynx.
1:01
Thank you very much.
1:02
And I'll just round it off by outlining
1:04
the mucosa of the nasal septum.
1:07
On the coronal projection, we have
1:11
mucosa outlining the maxillary sinus.
1:16
We also have mucosa outlining the left nasal cavity
1:21
and the superior boundary at the superior margin
1:25
of the ethmoidal air cells is the cribriform plate.
1:28
And we have mucosa outlining the ethmoidal
1:32
air cells, lateral to which lies the orbit.
1:36
In the sagittal projection, forget the tumor,
1:40
we have the cribriform plate, we have mucosa
1:44
of the nasal cavity, and we keep tracing
1:47
that back as far as the posterior choanae.
1:53
Don't forget the sphenoidal sinus as well.
1:57
So what are the compartments?
2:00
bounding the sinonasal cavity.
2:02
Laterally, we have the orbits.
2:06
Superiorly, we have the anterior cranial fossa.
2:11
Laterally, we have the infratemporal
2:13
fossa and masticator space.
2:18
And posteriorly, we have the nasopharynx,
2:23
as well as the pterygopalatine fossae,
2:26
which are not on this direct slice.
2:29
So in summary, the sinonasal cavity is an irregularly
2:33
shaped region with multiple subsites, which we will
2:36
cover in our next vignette, but the compartments that
2:40
bound it are the anterior cranial fossa superiorly,
2:44
the orbit superolaterally, the nasopharynx posteriorly,
2:52
the hard palate and oral cavity inferiorly, and
2:57
the masticator space and infratemporal fossa posterolaterally.
