The minor salivary gland tissue is scattered
0:04
throughout the aerodigestive system.
0:06
This actually is the source for things like the mucus
0:10
retention cyst, if you will, in the paranasal sinuses.
0:14
It also accounts for the salivary gland tissue that
0:18
lines the palate and it also goes into the
0:22
trachea and goes down into the bronchi.
0:23
So these are these tiny,
0:25
tiny little salivary cystic,
0:28
salivary glandular tissue
0:30
that is throughout the aerodigestive system,
0:33
including even the GI portion,
0:36
which would include the esophagus.
0:38
These have a relatively viscous mucinous saliva,
0:44
and they are innervated throughout the body
0:47
but in the head-neck region,
0:49
we usually think of the sphenopalatine,
0:51
the otic and the parasympathetic nervous system ganglia.
0:58
When you look at the distribution of the minor salivary
1:02
gland tissue, you see that the heaviest concentration
1:06
of minor salivary gland tissue is in the palate.
1:09
That includes the hard palate and soft palate.
1:13
Consequently, if you look at the distribution of minor
1:18
salivary gland neoplasms, it follows this quite closely.
1:23
So the most common location for a minor salivary
1:27
gland malignancy is in the palate.
1:31
You can see that there is quite a bit of
1:33
tissue also associated with the tongue
1:36
and the cheeks and the lips, as well as the maxillary
1:40
antrum which I mentioned and all the other different
1:43
portions of the aerodigestive system of the head and neck.
