My name is Prof. George Dias.
I'm the Professor of Anatomy
at the University of Otago,
School of Biomedical Sciences.
My research is in the area of
biomaterials and
surgical implants.
Today, I'm going to
talk about a region in
the head called the
infratemporal fossa.

There are two images.
On the left is the skull.
On the right, the skull
with the temporalis muscle
and part of the parotid
gland is present.
First of all, we know
the temporal fossa.
We have already covered
the temporal fossa
in my previous talk.
The temporal fossa is a
plateau which is found on
the lateral aspect
of the cranium
where the temporalis
muscle is attached.
If you want to describe a space
which is situated below
the temporal fossa,
what shall you call that?
Temporal fossa is where
the temporalis muscle
essentially is attached.
Therefore, a region inferior
to the temporal fossa,
can be called the
infratemporal fossa.
That is exactly where we
are going to look at.
In the skull diagram,
we will highlight the
ramus of the mandible.
This is a space that is situated
deep to the ramus
of the mandible.
Essentially, it is an
irregularly shaped space
lying beneath the
base of the skull,
situated between the
lateral wall of the pharynx
and the ramus of the mandible.
This space can also
be referred to as
the parapharyngeal space or
the lateral pharyngeal space.
