Hello, welcome to this lecture
which is on
"Cervical Lymphadenopathy".
My name is Graham Ogden,
Professor of Oral Surgery
at the University of Dundee.

The lymphoid tissue
in this region of the body
is found principally in the tonsils
situated between
the pillars of the fauces.
Secondly,
lying in the posterior tongue
also known as the lingual tonsil.
And thirdly, in the posterior wall
of the pharynx,
commonly referred
to as the adenoids.
Together these form something
known as "Waldeyer's ring".
In addition to that,
there are discrete nodes,
which we refer to as 'named' nodes,
scattered in the orofacial region,
which we will come on to describe
in a few minutes.
It is interesting to note
that at least 25% of all the nodes
in the body
are connected
to the cervical nodes.
Hence, it is perhaps
not so surprising
that many diseases can present
in the head and neck region.

When presented with a patient
in which you wish to examine
the lymphadenopathy in this region,
it is important to palpate
both the anterior
and posterior cervical nodes.
Where you suspect
that there is systemic disease
then it may be prudent
to also palpate
both the liver and the spleen.
For example,
where there is evidence
of generalised lymphadenopathy.
Please note, that we can also see
discrete swellings
caused by
expansion of the salivary gland,
the thyroid gland,
and other structures
in that region.
