Class 1 HEENT Flashcards
Bulging fontanel
a condition of the fontanel that may indicate increased intracranial pressure
Craniosynostosis
a condition that results from the premature closing of sutures before brain growth is complete; leads to a misshapen skull (flat spot)
Chloasma
facial discoloration common during pregnancy; also called the mask of pregnancy
Encephalocele
a neural tube defect characterized by the protrusion of nervous system tissue through a defect in the skull.
Facies
general appearance of the face, head, and neck that is characteristic of a specific condition
Graves disease
an autoimmune disorder that leads to an overproduction of thyroid- stimulating hormone; characterized by exophthalmia (bulging eyes).
Hashimoto disease
an autoimmune condition characterized by the production of anti- bodies against the thyroid gland, usually leading to hypothyroidism
Hyperthyroidism
overactivity of the thyroid
Hypothyroidism
underactivity of the thyroid; more common than hyperthyroidism
Macewen
sign associated with increased intracranial pressure after fontanels are closed. Percussion (tapping) on the skull at a particular spot (near the junction of the frontal, temporal and parietal bones) yields an unusually resonant sound in the presence of hydrocephalus or a brain abscess.
Mastoid fontanel
a third (abnormal) fontanel; common in Down syndrome
Microcephaly
a condition in which the circumference of the head is smaller than normal; associated with mental retardation
Molding
an abnormal shaping of the infant’s head caused by the shifting and over- lapping of bones during vaginal deliver
Myxedema
skin and tissue disorder usually caused by severe prolonged hypothyroid- ism; characterized by mucinous edema of face.
Ossification
bone tissue formation; begins in sutures after brain growth is completed
Salivary gland tumor
a growth or mass in any of the salivary glands, but most commonly occurring in the parotid gland.
Sternocleidomastoid
referring to the area extending from upper sternum to the mastoid process
Thyroglossal duct cyst
a palpable cystic mass in the neck; a embryologic remnant
Thyroid
largest endocrine gland.
Tic
a spasmodic contraction of the face, head, or neck.
Torticollis/wry neck
a condition in which the neck is twisted; often the result of birth trauma or intrauterine malposition; acquired torticollis may be caused by tumor, trauma, palsy of cranial nerve IV, muscle spasm, infection, or drug ingestion.
Transillumination
procedure used to evaluate suspected intracranial lesion or increasing head circumference in infants.
Bright light shined at a specific body part to see the structures beneath the skin.
Webbing
excessive posterior cervical skin
Anisocoria
unequal pupillary size
Cataracts
opacity/clouding of the lens; most commonly resulting from denaturation of the lens protein caused by aging.
Confrontation
test for estimating peripheral vision
Chorioretinal inflammation
an inflammatory process involving both the choroid and the retina; most commonly caused by laser therapy for diabetic retinopathy.
Cornea
part of the eye that is optically clear, has a rich sensory innervation, and is avascular
Corneal ulcer
a disruption of the corneal epithelium and stroma; associated with connective tissue disease.
Can occur from direct injury to the eye, or from a bacterial, fungal, or viral infection. inflammation resulting in pain
Diabetic retinopathy (background)
a condition characterized by dot hemorrhages or microaneurysms and the presence of hard and soft exudates.
Diabetic retinopathy (proliferative)
a condition characterized by development of new vessels as a result of anoxic stimulation; vessels grow out of the retina toward the vitreous humor (gelatinous tissue filling the eyeball behind the lens)
ECtropion
(lower?) eyelid turned away from the eye, outwards
ENtropion
eyelid turned inward, eyelashes rub against your eyeball
Episcleritis
inflammation of the superficial layers of the sclera anterior to the insertion of the rectus muscles.
inflammation of the episclera, which is the thin vascular outer coating of the eye wall, the sclera.
Exophthalmos
an increase in the volume in the orbital content, causing protrusion of the globes forward; most common cause is Graves disease
Glaucoma
a disease of the optic nerve wherein the nerve cells die, producing a characteristic appearance of the optic nerve (increased cupping). interocular pressure buildup damages optic nerve
Hemianopia
defective vision in half of the visual field
Hordeolum
a stye caused by staphylococcal organisms
Horner syndrome
interruption of sympathetic nerve supply to the eye, resulting in the triad of ipsilateral miosis (constricted pupil), mild pitosis (weak, droopy eyelid), and loss of hemifacial sweating; disrupted nerve pathway to 1 side from to face
Hypertelorism
eyes widely spaced apart
Lens
a biconvex, transparent structure located immediately behind the iris
Macula
also known as the fovea; near center of retina, needed to see clearly
Miosis
pupillary constriction
Mydriasis
pupillary dilation
Nystagmus
involuntary dysrhythmic movement of the eyes.
Papilledema
loss of definition of the optic disc/blind spot where optic nerve goes
intracranial mass, lesion, hemorrhage, meningitis -> increased pressure in/around brain (ICP) -> optic disc swelling
