Head, Neck, and Regional Lymphatics

1. Head, Neck, and Regional Lymphatics Health assessment

2. Lectures objectives • Identify the anatomic structures of the head and neck. • Identify the lymph nodes of the head and neck. • Describe the system-specific health history for the head and neck.

3. Lectures objectives • Demonstrate the physical assessment of the head and neck. • Describe normal findings in the physical assessment of the head and neck. • List common abnormalities found in physical assessment of the head and neck. • Explain pathophysiology of common abnormalities found in physical assessment of the head and neck.

4. Landmarks of the face. Bones of the skull

6. Overview • The integration of body systems and regions begins with the head and neck. • The head provides a means of identifying individuals through the uniqueness of hair, eyes, and facial characteristics. • With assessment of the head and neck, clues to the client’s nutritional status, airway clearance, tissue perfusion, metabolism, level of activity, sleep, rest, stress, and self-care abilities will be identified.

7. Anatomy and Physiology • The skull is made up of the bones of the cranium and the face. • The cranium includes frontal, parietal, temporal, and occipital bones. • The muscles of the face play a role in expression of emotions and assist in neck movement. • Movement of the facial muscles is controlled by cranial nerves V and VII. • The carotid arteries provide the blood supply to the head; the temporal artery supplies blood to much of the face. • The neck is supported and made mobile by vertebral processes and the sternocleidomastoid and trapezius muscles. • The hyoid bone, superior to the larynx, is the only bone in the body that does not directly articulate with another bone. It serves as a movable base for the tongue, and an attachment for muscles of the neck. • The thyroid gland is in the middle of the neck anterior to the trachea. The isthmus is the center, and the two lobes lie on either side of the trachea. • The nine sets of lymph nodes drain the head and neck.

8. Health History • Determine presence/absence of age- and gender-specific diseases of the head and neck • Common chief complaints • Neck pain or stiff neck • Hoarseness • Neck mass • Headache • Head injury

9. Evaluating Chief Complaint • Determine the following characteristics • Quality • Associated manifestations • Aggravating factors • Alleviating factors • Setting • Timing

10. Past Health History • Medical conditions • Surgeries • Medications • Injuries or accidents

11. Family Health History • Determine if family history of • Thyroid disease • Headache

12. General Approach to Head and Neck Assessment • Greet patient, explain assessment techniques • Environment • Quiet • Warm • Private • Adequate lighting • Upright sitting position • Compare right and left sides • Systematic approach • EQUIPMENT • Tape measure   ◆    Stethoscope   ◆    Cup of water (for evaluation of thyroid gland)

13. Assessment of the Head • Inspection • Shape • Symmetry • Palpation • Contour • Masses • Depression • Tenderness

14. Inspection and Palpation of the Scalp • Inspect • Lesions or masses • Normal findings • Scalp is shiny, intact, without lesions or masses • Abnormal findings • Bleeding, lesions, masses, hematomas

15. Assessment of the Face • Inspection • Shape • Symmetry • Normal findings • Symmetrical features • Palpebral fissures equal • Shape can be oval, round, or slightly square

16. Assessment of the Face • Abnormal findings • Deformed or absent structures • Asymmetry • More or less pronounced facial features • Diseases which may alter facial features: • Bell’s palsy, A temporary disorder affecting cranial nerve VII and producing a unilateral facial paralysis

17. acromegaly An enlargement of the skull and cranial bones due to increased growth hormone • hydrocephalus The enlargement of the head caused by inadequate drainage of cerebrospinal fluid, resulting in abnormal growth of the skull

18. Mandible • Palpate and auscultate the temporo-mandibular joint when the client opens and closes the mouth • Normal findings • No discomfort, joint articulates smoothly without clicking or crepitus • Abnormal findings • Pain, tenderness, crepitus

19. Neck • Inspection • Palpation • Normal findings • Full ROM, pain free, symmetrical muscles, no masses • Abnormal findings • Limited ROM, pain, asymmetrical muscles, masses

22. Thyroid Gland • Inspection • Palpation • Auscultation Normal findings Symmetrical movement with swallowing Adam’s apple more pronounced in males No masses, tenderness, or enlargement Absent bruit Abnormal findings Mass Enlarged gland Goiter Asymmetrical enlargement Presence of a nodule or bruit

23. hyperthyroidism   The excessive production of thyroid hormones, resulting in enlargement of the gland, exophthalmos (bulging eyes), fine hair, weight loss, diarrhea, and other alterations. • hypothyroidism   Metabolic disorder causing enlarged thyroid due to iodine deficiency.

24. Lymph Nodes • Inspection • Palpation • Location • Preauricular • Postauricular • Occipital • Submental • Submandibular • Anterior and posterior cervical chains • Tonsilar • Supraclavicular

26. Lymph Nodes • Normal findings • Unable to palpate or see nodes • Abnormal findings • Enlarged nodes • Able to palpate or see nodes • Tenderness • Firm, hard nodes

27. Position of the thumbs to evaluate the midline position of the trachea

28. Cushing syndrome. Facies include a rounded or “moon-shaped” face with thin, erythematous skin. Hirsutism may also be present, especially if the condition is caused by an adrenal cancer

29. Hyperthyroid facies. Note fine, moist skin with fine hair, prominent eyes and lid retraction, and staring or startled expression

30. Down syndrome. Note depressed nasal bridge, epicanthal folds, mongoloid slant of eyes, low-set ears, and large tongue

31. Hydrocephalus, with characteristic enlarged head, bulging fontanel, dilated scalp veins,

32. Early acromegaly. Note the coarsening of features with broadening of the nasal alae and prominence of the zygomatic arches

34. Left facial palsy. Facies include asymmetry of one side of the face, eyelid not closing completely, drooping lower eyelid and corner of mouth, and loss of nasolabial fold.
