(5) HENT Flashcards
What condition best describes a “form of cutaneous and dermal edema”?
Determine the cause:
Myxedema
Caused by: hypothyroidism (increased in deposition of connective tissue)
What condition best describes “prominent orbital ridges, enlarged frontal sinus, long face, enlarged maxillary sinus, large nose, prominent mandible, thickened lips”?
Determine the cause:
Acromegaly
Caused by: overproduction of GH from a pituitary tumor
What condition best describes “decreased facial expression, decreased blinking, staring”?
Determine the cause:
Parkinsonism
Caused by: Motor impairment
What condition best describes a “moon face, red cheeks, excessive hair growth”?
Determine the cause:
Cushing Syndrome
Caused by: Increased adrenal cortisol production
What condition best describes “facial and periorbital edema, pale skin”?
Determine the cause:
Nephrotic Syndrome
Caused by: loss of protein via the kidneys (proteinuria) that leads to low protein levels in the blood (hypoalbuminemia)
What condition best describes “unilateral swelling anterior to earlobe, unilateral swelling above the angle of the jaw”?
Parotitis (parotid gland swelling)
What are the (4) anatomical structures of the Auricle/Pinna (external ear)?
- Helix
- Anti-helix
- Lobule
- Tragus
Define air-filled cavity (tympanic cavity).
area of the middle ear that transmits sound by the ossicles
What are auditory ossicles?
3 bones in the middle ear: malleus, incus, stapes
What does the tympanic cavity connect to?
eustachian tube (which then connects to the nasopharynx)
Describe the tympanic membrane.
a thin opaque membrane held by malleus (barrier between outer and middle ear)
What is the function of the tensor tympani muscle? What nerve innervates the tensor tympani muscle?
Adjusts tension on the TM to adjust for loud noises
CN V (trigeminal nerve)
What are the (6) landmarks of the tympanic membrane?
- Short process of malleus
- Manubrium of malleus
- Cone of light
- Pars tensa (below the short process)
- Umbo (center)
- Pars flaccida (above short process)
What is the function of the cochlea?
What is the function of the semicircular canals?
Cochlea: sense of hearing/sound
Semicircular canals: maintain equilibrium/balance
What is the function of the auditory nerve (CN VIII)?
responsible for sound in the cochlear division and balance in the vestibular division
Large, visible bumps made of uric acid crystals; can be seen on helix of ear
Gout Tophi
What is “mastoiditis”? Cause?
inflammation of the mastoid bone; bacterial infection of the middle ear (otitis media) can travel into the air cells of the mastoid bone
What condition is best described?
inflammation of the external ear or ear canal; referred to “swimmer’s ear” because repeated exposure to water can make the ear canal more vulnerable to inflammation
movement of the pinna elicits pain
otitis externa (or cellulitis)
What condition is best described as “erythema, bulging to the middle ear” on an otoscope exam?
Otitis Media “Middle Ear Infection” (not effusion)
What condition best describes a “buildup of non-infectious fluid to the tympanic membrane” an otoscope exam?
Serous (Suppurative) Otitis Media
Define Conductive Hearing Loss (CHL).
Impairment of sound conduction in the middle or external ear
Define Sensorineural Hearing Loss (SNHL).
Cochlear nerve function impaired
What (2) tests examines for CHL and SNHL?
Weber and Rinne Test
What indicates a normal Weber test?
Sound heard bilaterally (no lateralization of sound)
