Thyroid Examination
Sana Rasheed
Akhtar Saeed Medical and Dental College
ANATOMY
• The thyroid gland is located in the anterior neck, spanning
between the C5 and T1 vertebrae. It is an endocrine gland,
divided into two lobes which are connected by an isthmus. It is
said to have a butterfly shape.
• It lies behind the sternohyoid and sternothyroid
muscles, wrapping around the cricoid cartilage and superior
tracheal rings.
• It is inferior to the thyroid cartilage of the larynx. The gland is in
the visceral compartment of the neck, along with the
trachea, oesophagus and pharynx. The compartment is bound
by pretracheal fascia.

5. Exposure of patient ( Dupatta off )
Proceed towards General Examination and Relevant History.
General Appearance:

Hyperthyroidism
1st Step : Inspection
• Examination of thyroid should be done in 3 positions.
• i. Front
• ii. Back
• iii. Front
I. EXAMINATION FROM FRONT
Make the patient sit comfortably on a stool and inspect the thyroid with neck
slightly hyperextended and inspect the thyroid from the front.
For Short neck patients, PIZILLO Method:
Ask the patient to clasp the hands over the occiput and push the head
backwards against the resistance of the clasped hands. This makes the thyroid
more prominent.
1. First, notice shape of the swelling, and it’s situation.
2. Shape Oval/globular/spherical pear or irregular – diffuse or localised
3. Location Whether it is on one side of the midline, IN the midline, or it
extends on both the sides.
One side of Midline
In the midline
Extends on both sides of midline
Now notice the EXTENT of the swelling.
Particularly the lateral border in relation
to sternomastoid.
And the lower border in relation to the
suprasternal notch of the sternum
A thyroid swelling always lies deep to the
sternomastoid muscles.
Demonstrated by contracting the sternomastoids.
Then note whether the lower border ends above the
suprasternal notch or it extends behind the suprasternal
notch.
Both the borders are to be appreciated.
Next, inspect the surface of the
swelling
A simple goiter and a single
nodule have a smooth
surface.
A multinodular goiter has a
nodular or bosselated
surface.
Then, Inspect the Skin over the swelling.
1. Redness and edema : suggestive of
inflammation
2. Scars of previous surgery
3. Sinuses
4. Dilated veins
5. Pigmentation/ulceration
• A scar from previous thyroid surgery tells us this is a recurrent thyroid swelling
• A sinus in middle of the neck may discharge mucus like fluid is thyroglossal fistula
Pulsatility : watch the swelling
for a few seconds quietly for
pulsatility. Pulsatility shows
presence of an artery.
Deglutition test
Ask the patient to do DEGLUTTION
TEST
Give him/her a glass of water. Ask
them to take a sip and put away the
glass. Then swallow the water. Notice
the movement of swelling.
Thyroid swelling moves up with
deglutition.
• Other Swellings that move up on
degluttition
A swelling that is not attached to the pretracheal fascia like
LIPOMA will not move upwards during deglutition
Thyroid cartilage may move upward but not the swelling
Tongue protrusion test
1. If the swelling is in the midline, tongue protrusion test is done to rule out
thyroglossal cyst.
2. Ask the patient to extend the neck and open the mouth wide.
3. Now keeping the mouth ask the patient to move the tongue out and in.
4. If swelling moves upwards – thyroglossal cyst
5. This sign is diagnostic of thyroglossal cyst which is connected to the
foramen cecum of the tongue.
6. A thyroglossal fistula also moves upwards with the tongue as it is also
connected to foramen cecum.
Pemberton sign: to diagnose retrosternal goiter compression:
••Raise both arm over head, until they touch the ears
••Maintain the position for a while
••Congestion of face and distress occurs due to obstruction of great veins
of thorax
Facial flushing seen
PAMBERTON’S SIGN for retrosternal goiter.
Retrosternal goiter
Multinodular goiter can become so much enlarged resulting in the
extension of the enlarged gland into the thoracic region and can
cause Superior Vena Cava compression Dilatation of subcutaneous
veins over anterior part of upper thorax.
PALPATION
Let the patient sit in comfortable
position seating with neck extended.
Ask for consent.
• Warm both hands gently
• Always ask about tenderness (check patient’s facial expressions) and compare temperature of swelling
with surrounding normal skin with dorsal surface of hand.
1. Then stand behind the patient.
2. Place the hands around the neck with the thumbs over the occiput and
tips of the other fingers over the front of the neck.
3. This is the standard method for palpation of the thyroid gland.
4. The flexion of the neck can be adjusted by the grip between thumb over
the occiput and index fingers under the chin.
5. Now keep the neck slightly flexed to relax the deep cervical fascia and ask
the patient to make a swallowing movement as you are palpating.
6. As thyroid moves up and down, lower border can be appreciated and
nodules if present can be felt more easily.
7. Palpate the anterior surfaces of the lobes, one by one by reclining the
head to the side (same side as the lobe being palpated)
Check:
PALPATE TRACHEA AND CAROTID PALPATIONS
1. To palpate the trachea, first note position of the larynx
then palpate the trachea downwards.
2. May be easy to appreciate its displacement to opp.
Side in unilateral goiter.
3. In bilateral goiter, trachea may not be palpable. So
first note the position of the larynx, and the position
of the trachea over the suprasternal notch.
• Palpate tracheal rings in the suprasternal notch. If they are not present,
retrosternal extension is suspected.
LAHEY’S METHOD for deep surface of the gland
Now stand in front of the patient.
Extend the neck slightly
To palpate right lobe push the right lobe with your right hand to right side and
palpate with left hand.
Repeat on left side.
Crile’s method for palpation of small nodules
Place the thumb on the thyroid while the patient
swallows; this method is used to diagnose doubtful
nodules
• Fixity to skin Pinch the skin over
the swelling to look for fixity to
skin and (fixity suggests
malignant infiltration)
• Test the mobility of the skin in
vertical and horizontal direction.
Kocher’s test (for scabbered trachea)
• To rule out tracheal narrowing.
• Ask the patient to extend neck and take
deep breaths.
• Compress swelling from both sides.
• Stridor on compression of lateral lobes
indicates narrowing of the trachea.
• It may also be seen in a malignant thyroid
infiltrating the trachea.
PALPATE CAROTID ARTERY PULSATIONS
(Berry’s Sign)
• Palpate carotid artery pulsations on
transverse process of 6th cervical vertebra.
• In unilateral goiter, compare affected side
with normal side.
• If goiter is large:
POSITIVE >>>>
Percussion
Auscultate for carotid and thyroid bruit
Bruit – increased vascularity
SIGNS OF THYROTOXICOSIS
Features of Primary Thyrotoxicosis
1. Eye signs
2. Tachycardia
3. Tremors
4. Moist skin
5. Thyroid bruit
EYE SIGNS
• Lid retraction –Stellwag’s sign - upper lid raised & lower lid normal --
Starring look with infrequent blinking and wide palpebral fissures.
• von Graefe’s sign - Lid lag sign. Tested by asking the patient to look up
and down many times fixing the
EYE SIGNS
• Exophthalmos
• Bulging of the eyeball
• Strip of white sclera is visible between the
iris and lower eyelid.
Naffziger’s test: Go behind the patient, extend
the neck, see through the supraciliary ridge,
you can diagnose exophthalmos
EYE SIGNS
• Joffroy’s sign - Absence of wrinkling of forehead. The patient looks
the roof of the room without forehead wrinkling.
• MÖbius sign - Inability to converge the eyeball.
• Jellinek’s sign - Increased pigmentation of eyelids.
• Check for pretibial myxedema- hypothyroidism
EYE SIGNS
Ophthalmoplegia (malignant exophthalmos)
• – Weakness of ocular muscles due to edema and cellular infiltration of
these muscles.
• – Paralysis of superior rectus, inferior oblique and lateral rectus.
• – On paralysis of these muscles, patient is unable to look upwards and
outwards.
EYE SIGNS
Chemosis
– Due to obstruction of venous and
lymphatic drainage of conjunctiva by
increased retro-orbital pressure.
EYE SIGNS
• Perform ankle reflex
• Auscultate the heart
• Auscultate the chest
• Palpate the Spine for tenderness
• Say thanks to patient and cover the patient.
