EENT Flashcards
Define exophthalmos. Who typically experiences this disorder?
increased axial projection (eye protrusion)
Common finding in. thyroid eye disease and found in about 60% of patients
Define ptosis and causes
Drooping of the upper eyelid.
Causes: senescence (deterioration with age), myasthenia gravis, or damage to the oculomotor nerve (CNIII)
What condition is this?
More common in elderly population
Inward turning of the lid margin. The lower lashes irritate the conjunctiva and lower cornea. Lower lashes may be invisible when turned inward
Entropion
What condition is this?
Lower lid margin turns outward, exposing the palpebral conjunctiva. When this occurs the eye no longer drains well
More common in older adults
Ectropion
What condition is related to elevated intracranial pressure that causes intra-axonal edema along the optic nerve, leading to engorgement and swelling of the optic disc?
papilledema
what sinuses are typically affected when patients present with sinus pressure or sinus infection?
Maxillary sinus (near the cheeks) and ethmoid sinus (near the bridge of the nose)
at what age does the frontal sinus develop. Describe their location
7 years old; near the forehead
What are causes of rhinorrhea
Viral infections. allergic rhinitis (hay fever), and vasomotor rhinitis (itching favors allergic cause)
What term defines unequal pupils
aniscoria
movement of the auricle and tragus is painful in _____ but not painful in _____.
acute otitis externa (inflammation of the ear canal)
not painful in otitis media (inflammation of the middle ear)
What are causes of sensorineural hearing loss
loud noise exposure, inner ear infections, trauma, acoustic neuroma, congenital and familial disorders, and aging
What are the effects of sensorineural hearing loss
Higher registers are lost, so sound may be distorted
Hearing worsens in noisy environment
Voice may be loud because hearing is difficult (due to cochlear nerve and neuronal impulse transmission to the brain is affected)
What are the causes of conductive hearing loss
foreign body, otitis media, perforated eardrum, and otosclerosis of ossicles
What are the effects of conductive hearing loss
little effect on sound
Hearing seems to improve in noisy environment
Voice remains soft because inner ear and cochlear nerve are intact
Acute otitis media with purulent effusion is commonly caused by what bacteria
S. pneumoniae or H. influenzae
xerostomia
dry mouth
white, cottage cheese‐like lesions that can be easily removed with swab is called what?
What is it treated with
Thrush (candida - fungal); treated with anti-fungal
recurrent single or multiple shallow, painful ulcers, that are scattered or grouped are called what?
What is treatment?
Aphthous ulcers
Symptomatic treatment with “Magic Mouthwash”
Multiple ulcers on tonsils, soft palate, uvula (May also
have lesions on hands and soles of feet).
What population does this primarily affect?
Herpangina (Coxsackie virus)
Seen more in kids
painless punched out ulceration on lip, tonsil or palate is called what?
What is treatment?
Syphillis chancre
Treated with PCN.
painful, similar in appearance to aphthous ulcers, but only on mucosa attached to bony
structures is descriptive of what condition?
What is treatment?
Herpes
Treated with anti‐virals.
halitosis
malodorous breath
what structures are part of the oropharynx
uvula, soft palate, palatine tonsils, and posterior wall of the oropharynx
A hump in the middle of the nose is called what?
dorsum convexity
Saddling of the middle of the nose is called what?
dorsum concavity
asymmetric protrusion of the tongue suggests a lesion of what cranial nerve? What way would the tongue turn if there is a lesion?
CN XII
tongue points toward the side of the lesion
what are common causes of otitis media?
- edema and congestion in Eustachian tube
- refulux of bacteria from the nasopharynx
- accumulation of secretions in middle ear increase pathogen growth
Name the structures of the middle ear
malleus, incus, stapes, tympanic membrane (eardrum), tympanic cavity, semicircular canals
Name the structures of the inner ear
cochlea, vestibular nerve, cochlear nerve, estachian tube
Name the structures of the outer ear
auricular lobule (earlobe)
Concha
antihelix
tringular fossa
scapha
helix
temporal muscle
temporal bone
external acoustic meatus (ear canal)
Extraocular muscles:
What movement does the superior rectus muscle control?
What cranial nerve moves it
Moves the eye upward (elevation)
CN III
