Head and Neck Evaluation

Techniques of Examination

Head:    Hair = fine — hyperthyroidism, coarse — hypothyroidism

Scalp = Redness + scaling — seborrheic dermatitis, psoriasis

Skull = Enlarged — hydrocephalus, Paget’s disease of bone

Tenderness — trauma

Face = read up on this topic

Skin = Hirsutism (excessive facial hair) in women

Eyes:   Visual Acuity:

20/200 — patient can read print at 20 ft. Normal person reads at 200 ft.

“20/40 corrected” — can read at 40 line w/ glasses

Myopia = impaired far vision

Presbyopia = impaired near vision, in old people — sees better when far

Legal blindness = vision is better eye w/ glasses — 20/200

Also due to constricted field of vision (20 degrees or less in better eye)

Visual Fields by Confrontation

Screening starts in temporal fields b/c most defects here — homonymous

heminanopsia, bitemporal hemianopsia, quadrantic defects

“Fish bowl test” – wiggle fingers — patient normally sees both fingers

same time

Left temporal hemianopsia = patient’s left eye doesn’t see fingers until

crossed line of gaze

Temporal defect in visual field of one eye suggests nasal defect in other eye –

left homonymous hemianopsia

Enlarged blind spot — glaucoma, optic neuritis, papilledema (these affect optic

nerve)

Position and Alignment of Eyes

Abnormal protrusion — Graves’ disease, ocular tumors

Eyebrows

Scaliness — seborrheic dermatitis

Lateral sparseness — hypothyroidism

Eyelids

Blepharitis = inflammation of eyelids along lid margins — crusting/scales

If eyelids don’t close — damage corneas

Lacrimal Apparatus

Excessive tearing        — increased production: conjuctival inflammation, corneal irritation

– impaired drainage: ectropion (lower lid turned outward so

doesn’t drain right), nasal duct obstruction

Conjunctiva and Sclera

Yellow — Jaundice

Local redness — nodular episcleritis   Cornea and Lens-Opacities

Iris:      Iris abnormally far forward — narrow angle w/ cornea — cast crescent shadow

Narrow angle — risk for acute narrow-angle glaucoma = sudden increase in

intraocular

pressure when block aqueous humor drainage

Pupils: Miosis = pupil constriction

Mydriasis = pupil dilation

Pupillary abnormalities: benign anisocoria, Horner’s syndrome. . .

Anisocoria = pupillary inequality < 0.5 mm — if pupillary reactions normal, then

anisocoria benign

Direction reaction (pupillary constriction in same eye)

Consensual reaction (constriction in opposite eye)

If reaction to light impaired — test near reaction in normal light

Ask patient to look alternately at finger and into distance behind it — watch for

constriction with near effort — diagnose Argyll Robertson , tonic (Adie’s)

pupils

Extraocular Muscles

Asymmetry of corneal reflections — deviation from normal ocular alignment

Temporal light reflection on one cornea — nasal deviation of that

Nystagmus = rhythmic oscillation of eyes

Sustained nystagmus w/in binocular field of gaze — neurologic problem

Lid lag — hyperthyroidism– can see rim of sclera between upper lid and iris

Lid seems lag behind eyeball

Left CN VI paralysis — eyes conjugate in right lateral gaze, not in left lateral gaze

(when looking left, left eye doesn’t follow)

Poor convergence — hyperthyroidism

Opthalmoscopic Exam

Contraindications for mydriatic drops (for pupil dilation) — head injury/coma-

need to observe pupillary reactions  OR — suspicion of narrow-angle

glaucoma

Macular degeneration — poor central vision in old people – can be hemorrhages,

Exudates, cysts, “holes”

Vitreous floaters = dark specks/ strands between fundus and lens

Cateracts = densities in lens

Ear:     Auricle

Otitis externa = move auricle — pain

Otitis media = move auricle — no pain (but can have tenderness behind ear)

Ear Canal and Drum

Exostoses = nontender, nodular swellings covered by normal skin in ear canal

Nonmalignant overgrowths

Acute otitis externa — canal swollen, narrowed, moist, pale, tender, red

Chronic otitis external — skin of canal thicken, red, itchy

Acute purulent otitis media — red, bulging drum

Serous effusion — amber drum

Auditory Acuity — test hearing by whispering into one ear

Air and Bone Conduction

Distinguish conductive and sensorial hearing loss

Weber Test = test for lateralization

Unilateral conductive hearing loss — sound lateralized to impaired ear – due to

acute otitis media, perforated ear drum, obstruction of canal

Unilateral sensorial hearing loss — sound lateralized to good ear

Conductive hearing loss — sound heard through bone as long/longer than in air

Sensorial hearing loss — sound heard longer through air

Nose and Paranasal Sinuses:

Tenderness of nasal tip — infection (furuncle)

Deviation of lower septum seldom obstructs air flow (pretty common)

Lower anterior part of septum — source of epistaxis = nosebleed

Septal perforation — trauma, surgery, cocaine, amphetamines

Viral rhinitis — mucosa red, swollen

Allergic rhinitis — mucosa pale, bluish, red

Polyps = pale, semitranslucent masses from middle meatus

Ulcers — nasal use of cocaine

Acute sinusitis — local tenderness, pain, fever, nasal discharge – Dx by transillumination

Mouth and Pharynx:

Denture Sore Mouth — bright red edematous mucosa beneath denture

Lips:    Cyanosis, pallor

Oral Mucosa: read up on this topic if necessary

Gums and Teeth:

Gingivitis — redness, swollen interdental papillae

Lead poisoning — black line

Roof of Mouth:

Torus palatinus = midline lump

Tongue and Floor of Mouth:

Lesion of CN XII — asymmetric protrusion of tongue

Cancer of tongue – second leading cause of cancer in mouth (1st is lip)

Suspect persistent nodule/nodule that’s red/white

Induration — increase malignancy

Most often on side of tongue, can also be at base

Paralysis of CN X — soft palate fails to rise, uvula deviates to opposite side

Lymph Nodes:

Feel in sequence – Preauricular — Posterior auricular — Occipital — Tonsillar — Submandibular

– Submental — Superficial cervical — Posterior cervical — Deep cervical chain –

Supraclavicular

“Tonsillar node” — pulsates = carotid artery

Small, hard, tender “tonsillar node” high in mandible and SCM = styloid process

Enlargement of supraclavicular node — metastasis form thoracic or abdominal malignancy

Trachea and Thyroid Gland:

Tracheal Deviation — masses in neck, mediastinal mass, atelectasis, large

pneumothorax

Goiter = enlarged thyroid gland

Tenderness — thyroiditis

Hyperthyroidism — localized systolic or continuous bruit

Special techniques:

Exopthalmos =  abnormal protrusion of eye

Nasal Lacrimal Duct Obstruction– regurgitation of mucopurulent fluid from puncta

Swinging Flashlight Test = determine if reduced vision due to ocular disease or optic

nerve

Damage optic nerve — afferent stimulus to midbrain decreased so pupil dilates from

constricted state — Afferent pupillary defect (Marcus Gunn pupil)

Transillumination of Sinuses – absence of glow — thick mucosa in frontal or maxillary

sinus,   can also be due to absence of sinus.
