examination of thyroid gland

Transcript of Thyroid gland

Page 1: Thyroid gland
Page 2: Thyroid gland

The examination consists of three portions:

Inspection, Palpation, and Synthesis of data from these techniques

Page 3: Thyroid gland

AGE:

Puberty- simple goitre,papillary carcinoma,

Middle age- multinodular goitre,colloid goitre,follicular carcinoma. Old age- Anaplastic carcinoma

Page 4: Thyroid gland

SEX:Simple goitre is more common in Females

thyrotoxicosis is 8 times more common in females. Thyroid carcinoma is more often seen in females 3:1.

OCCUPATION:Thyrotoxicosis is common in people working under

stress and strain. .

Page 5: Thyroid gland

RESIDENCE:Goitre belts in india like Himalayas, Vindyas,

Satpuda ranges. Areas producing chalk or lime stone like Derbyshire

1.DESCRIBE IN DETAILS ONSET AND PROGRESSION OF THE SWELLING, 2.PRESSURE EFFECTS; 3.SYMPOTOMS OF HYPOTHYROIDISM

4.SYMPOTOMS OF HYPERTHYROIDISM; 5.SYMPTOMS OF MALIGANANCY.

Page 8: Thyroid gland

Tilt the patients head back a bit

Use tangential lighting from the tip of the patients chin

Ask for swallowing

Observe the thyroid cartilage, cricoid cartilage and the thyroid gland raising with swallowing

Page 9: Thyroid gland

Inspection: Anterior Approach

The patient should be seated or standing in a comfortable position with the neck in a neutral or slightly extended position.

Cross-lighting increases shadows, improving the detection of masses.

To enhance visualization of the thyroid, you can: Extending the neck, which stretches overlying

tissues Have the patient swallow a sip of water, watching

for the upward movement of the thyroid gland.

Page 10: Thyroid gland

Inspection: Lateral Approach After completing anterior inspection of the

thyroid, observe the neck from the side. Estimate the smooth, straight contour from

the cricoid cartilage to the suprasternal notch. Measure any prominence beyond this

imagined contour, using a ruler placed in the area of prominence.

• Size : ……X………..• Shape : Ovoid / Spherical / Irregular• Location: One side / mid line / both sides of

mid line• Extent: Horizontal from Sternomastoid…

Vertical from Suprasternal Notch… The swelling is: Under Sternomastoid / Not

under sternum• Surface: Smooth / Nodular / Bosselated

Page 12: Thyroid gland

• Skin over the swelling:Redness and edema, Scars of previous surgery, Sinuses, Dilated veins

• Pulsatility : Present / Absent

• Movement with Deglutition: Present / Absent

• Protrusion of Tongue (For midline swellings): Present / Absent

Page 13: Thyroid gland

Do not press to much the thyroid

You can loose the sensitivity of your fingers

Try to not strangle your patient

Page 14: Thyroid gland

The following information could be obtained

volume consistency mobility of the thyroid gland surface temperature

Page 15: Thyroid gland

Palpate the thyroid gland from behind

Localize anatomic boundaries

Thyroid isthmus is often palpable

Thyroid lobes are barely or not palpable

The consistency is rubbery, similar to that of sternomastoid muscle

Page 16: Thyroid gland

Temperature: Normal / Raised Tenderness : Present / Absent Size: … X … Shape: Ovoid / Spherical / Irregular Extent: Horizontal from Sternomastoid…

Vertical from Suprasternal Notch… Plane of the swelling : Under Sternomastoid /

Under Strap muscles/ Deep to deep fascia.

Page 17: Thyroid gland

A) In case of affection of entire gland,• i) Surface : Smooth / Bosselated• ii) Consistency : Uniform (Soft / Firm / Hard) /

Variable• iii) Retrosternal Extension : Present / AbsentB)In case of Single Nodule Or One Lobe affection• i) Location : Lobe / Isthmus• ii)Consistency: Soft / Firm• iii) Is the rest of the gland palpable ? Yes / No

Page 18: Thyroid gland

• Stand behind the pt.

• Place your hands around the neck with the thumbs over the occiput and tips of the other fingers over the front of the neck.

• Flex the neck to relax deep cervical fascia.

• Ask the pt to swallow to look for lower border and nodules.

• To palpate anterior surface, incline the head to the side being examined to relax overlying sternomastoid muscle.

Page 19: Thyroid gland

Palpation: Anterior Approach

1. The patient is examined in the seated or standing position.

2. Attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch.

3. Use one hand to slightly retract the sternocleidomastoid muscle while using the other to palpate the thyroid.

4. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland.

Page 20: Thyroid gland

Palpation: Posterior Approach

1. The patient is examined in the seated or standing position.

2. Standing behind the patient, attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch.

3. Move your hands laterally to try to feel under the sternocleidomstoids for the fullness of the thyroid.

4. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland.

Page 21: Thyroid gland

Stand in front of the patient. Extend the neck slightly. Keep a thumb over the lobe to be examined. Ask the pt to swallow. Feel for small nodules.

Page 22: Thyroid gland

• In short and flat neck ————Pizillo’s Method makes gland prominent

• Ask pt to clasp his hands over the occiput• Push the head backwards against the resistance

of the clasped hand

Page 23: Thyroid gland

Done to palpate deep or postero medial surface of the gland.

Stand in front of the patient. Extend the neck slightly. Push the thyroid gland laterally to displace it

from tracheo esophageal groove. Palpate the posterior surface for nodules with

other hand.

Page 24: Thyroid gland

• Done in large, bilateral goiter to rule out tracheal narrowing.

• Extend the neck.• Ask the patient to take deep breaths through the

mouth.• Compress the swelling from both the sides.• Appearance of stridor with slight compression of

lateral lobes due to Narrowing of trachea ( Scabbard trachea).it is seen in case of large and longstanding multinodular goiter and Ca thyroid infiltrating trachea.

Page 25: Thyroid gland

Lahey’s Method of Palpation of Thyroid: Nodules Present / Absent,If present consistency of nodule

Crile’s Method of Palpation of Thyroid: Nodules Present / Absent

Palpabale Thrill : Present / Absent Fixity to skin : Fixed / Not Fixed Mobility : Horizontally Mobile / Fixed ;Vertically

Mobile / Fixed Palpation of Trachea : Palpable / Not Palpable,

Deviated / Not deviated Kocher’s Test : Positive / Negative Palpation of carotids : Berry’s Sign Positive / Negative

Page 26: Thyroid gland

Percussion over sternum : Resonant / Dull

Ascultaion of gland : where to ascultate? Lower pole or

Upper pole? why?

Page 27: Thyroid gland

Hoarseness of voice : Present / Absent Edema of face and legs: Present / Absent Delayed relaxation of deep reflexes : Ankle

jerk ,Knee jerk History of lethargy: Present / Absent

Page 28: Thyroid gland

Dilated veins : Present / Absent Congestion and puffiness of face: Present / Absent Palpate for tracheal rings: Present / Absent Percuss over sternum: Resonant / Dull Pemberton’s sign: Positive / Negative Horners syndrome: (Ptosis,Constricted pupil,

Enophthalmos, Absent cilio-spinal reflex, Anhydrosis) : Present / Absent

Page 29: Thyroid gland

Eye signs Lid retraction : Dalrymple’s sign : Present / Absent Lid lag : Von Graeffe’s sign: Present / Absent Incomplete, infrequent blinking: Stellwag’s sign : Present /

Absent Exophthalmos : strip of sclera under inf limbus: Present /

Absent Naffziger’s Method : Present / Absent Wrinkling of forehead : Joffroy’s sign : Present / Absent Eversion of upper eye lid : Gifford’s sign: Positive / Negative Convergence : Mobius’ sign : Present / Absent Chemosis: Congestion and edema of conjunctiva, Corneal ulcers, diminished vision , Ophthalmoplegia

Page 30: Thyroid gland

To note the amount and the degree of exophthalmos.

Stand behind the patient. See from above. Observe the eyes in supraorbital plane,if corneal

limbus is visible then it is exophthalmos.

Page 31: Thyroid gland

Tremors : Outstretched Hand : Present / Absent Protruded tongue: Present / Absent Tachycardia : Heart rate = …. Bounding pulse:

Present / Absent Warm and moist skin : Present / Absent Pretibial Myxoedema : Present / Absent Bruit, Thrill: Present / Absent

Page 32: Thyroid gland

Neck : Enlarged and hard lymph nodes. Skull surface : Hard nodules. Long bones : Deformity and tenderness. Chest : Effusion and consolidation. Abdomen : Nodular Liver and ascites.

Page 33: Thyroid gland

Berry’s sign: Palpate the Carotid pulsations against the transverse process of the 6th cervical vertebra b/w post border of thyroid and sternomastiod.

In Ca thyroid, Carotid pulsations is weak or absent. Due to Infiltration of carotid sheath .

In benign goiter pulsations are well felt as carotid sheath pushed backwards.
