axillae.
Lymph nodes of the neck and their drainage
Demonstrate the correct palpation technique for all head and neck lymph node chains.
o When you palpate the neck lymph node chains look for tenderness, mobility, consistency,
size and symmetry. Use the table above to find the proper location for each node.
Properly perform palpation of the thyroid gland by both anterior and posterior
approaches.

o Anterior approach: The examiner stands in front of and facing the patient and flexes the
patient’s neck slightly forward to relax the SCM muscle. The examiner then uses the
fingers of his left hand to displace the trachea slightly to the patient’s left. The examiner
then checks the consistency and configuration of the left thyroid lobe with and without
swallowing. To do this, he/she palpates the full length of the left lobe using the fingertips
of his/her right hand and palpating in a posteriomedial direction. The hands are reversed
and this technique repeated for examining the right lobe.
o Posterior approach: The examiner stands behind the seated patient, placing his hands
around the patient’s neck. Depending on patient’s neck size and examiner’s preference,
the examiner may chose to slightly extend or flex the patient’s neck. The examiner
correctly positions his/her fingers and systematically palpates both thyroid lobes with and
without swallowing. Each time the patient swallows; the examiner pushes the trachea to
one side with the fingers of one hand and rolls the fingertips of the other hand over the
full extent of the thyroid gland palpating in a posteriomedial direction. (done for both
lobes).
Define the importance of palpation of the thyroid gland for consistency and size.
o When palpating the thyroid gland, please look for size, symmetry, consistency,
tenderness, nodules and mobility. The thyroid should be similar in consistency to muscle
tissue. The left thyroid lobe is typically slightly larger than the right lobe. Use the
swallowing tests for thyroid size and the adherence of the thyroid to surrounding tissues.
If the thyroid gland is enlarged, auscultate over the lateral lobes with a stethoscope to
detect a bruit. This can sometimes be heard with hyperthyroidism.
State the symptoms and physical exam findings associated with hyperthyroidism and
hypothyroidism.
o An enlarged thyroid may be associated with hyperthyroidism, hypothyroidism, or a
simple or multinodular goiter of normal function.

Chapter Eleven:
Properly perform inspection of the buccal mucosa, gingivae, teeth, tongue, tonsils, palate,
salivary glands and uvula of the oral cavity.
o Step 1: MUST look at the patient’s wide-opened mouth with a light.
o Buccal mucosal for any lesions, color changes or white patches, injection, swelling,
papules, ulcers, erosions, painful areas, and hemorrhages (petechiae).
o Condition of teeth and gums check for state of dentition, receding gums, malformation
or discoloration of teeth, caries, hygiene.
o Tongue can be described as geographic or smooth, if there are any lesions, color
changes, ulcers, masses etc. Tongue should be pale pink, glistening and without growths
or lesions.
o Uvula is located midline, same color as palate and aids in closing off nasopharynx and
with swallowing.
o Hard palate (anterior) and soft palate (posterior)- look for ulceration, masses, white
plaques, swelling.
o Stenson’s Ducts visualize the area of the opening opposite the 2nd upper molars.
o Floor of mouth patient is asked to elevate his tongue to the roof of his mouth so that
examiner can visualize any mucosal lesions.
Describe the locations of Stensen’s and Wharton’s ducts and state the purpose of each.
o Opening of Stenson’s ducts: opposite the 2nd upper molars (parotid gland duct); The
ducts from the parotid glands (the salivary glands located in the cheek around the angle
of the jaw) exit from the cheeks.
o Wharton’s ducts located on either side of the frenulum at the base of the tongue
(drainage from submandibular salivary gland duct).
Define relevant symptoms in the diagnosis of oral cavity disorders.
o Pain
o Ulceration
o Bleeding
o Mass
o Halitosis (bad breath)
o Xerostomia (dry mouth)
Define the following terms: dysphagia ,dysphonia, xerostomia, ptyalism and deglutition.
o Dysphagia: difficulting is swallowing
o Dysphonia: change in voice, customary with laryngeal disease
o Xerostomia: dry mouth due to reduced or absent salivary secretion
o Ptyalism: excessive production of saliva
o Deglutition: The act of swallowing, particularly the swallowing of food.

Properly perform palpation of the tongue and floor of mouth.
o Tongue: Patient is asked to stick his/her tongue out onto a piece of unfolded gauze that is
then wrapped around it. The tongue is palpated with the fingers of the free hand with
special attention given to the lateral sides (palpate the full length). Lateral margins are
palpated carefully because 85% of lingual cancers are found in this area. Describe any
palpable lesions or induration. FYI: The anterior 2/3 of tongue is innervated by facial
nerve and the posterior 1/3 by the glossopharyngeal nerve. The tip of the tongue tastes
sweet, the posterior 1/3 tastes sour or bitter and the lateral tongue tastes salt.
o Floor of mouth: Patient is asked to elevate his tongue to the roof of his mouth. The
examiner then palpates the floor of the mouth and the opening of Wharton’s ducts located
on either side of the frenulum at the base of the tongue (submandibular salivary gland
duct). This is done by placing a gloved finger under the tongue and palpating the entire
floor of the mouth for lesions, masses, tenderness, swelling etc.
Assess function of Cranial Nerves IX, X, and XII by testing the gag reflex, tongue
protrusion and vocalization of the sound “ah”.
o Observes uvula as patient says”ah” (CN IX, X): Symmetrical elevation of the soft palate
with the portion of the uvula attached to the soft palate remaining midline as the patient
says “ah” demonstrates normal coordinating function of CN’s IX and X.
o Tests gag reflex (CN IX, X)- Symmetrical elevation of the soft palate seen with a gag
indicates intact CN’s IX and X.
o Evaluates tongue protrusion (CN XII): Observe for fasciculations while the tongue rests
on the floor of the mouth. Observe the position of the tongue as the patient is asked to
“stick out your tongue”. Protrusion in the midline indicates intact hypoglossal nerves (CN
XII).
State the normal and abnormal findings for each nerve tested.
o Refer to objective above.
Summarize typical examination features and risk factors for oral cavity carcinomas.
o Carcinoma of the lip accounts for 30% of all cancers in this area and approximately 0.6%
of all cancers. Most of these malignant tumors are squamous cell carcinomas. The lower
lip is the site most frequently involved (95%). The patients are usually 50-70 years of
age, with a strong male predominance (95%). Squamous cell carcinoma is characterized
by a hard, infiltrative, usually painless ulcer.
o The risk factors that predispose to squamous cell carcinoma of the oral cavity are the
same as for leukoplakia:
Smoking
Spirits (alcohol)
Spices
“5 S’s”
Syphilis
Spikes (ill-fitting dentures)
