HEENT Flashcards
definition: 2 paired salivary glands that lie superficial to and behind the mandible
parotid glands
definition: lies deep to the mandible; can present an airway emergency when enlarged
submandibular gland
artery that passes superficially just in front of the ear
superficial temporal artery
definition: protect the cornea from drying out, inhibits microbial growth, and gives a smooth optical surface to the cornea
tears
tear fluid comes from ________ _______ and drains into the __________ _________ into the ____________ _________ and into the nose via the ____________ _____________
lacrimal gland; lacrimal punctum; lacrimal sac, nasolacrimal duct
definition: innermost layer of the eye; layer that eyeball focuses light onto
retina
definition: controls pupillary size
muscles of the iris
definition: controls the thickness of the lens, allowing the eye to focus on near and distant objects
ciliary body
fills the anterior and posterior chambers of the eye
aqueous humor
the posterior part of the eye; contains the retina, choroid, fovea, macula, optic disc, and retinal vessels
fundus
name the three compartments of the ear
- external ear
- middle ear
- inner ear
contains the auricle, ear canal, tympanic membrane
external ear
contains ossicles (incus, malleus, stapes) and eustachian tune which connects the middle ear to the nasopharynx
middle ear
contains the cochlea (senses and codes vibrations) and cochlear nerve (receives nerve impulses which are sent to the brain)
inner ear
which pathway of hearing starts at the external ear through the middle ear?
the conductive phase
which pathway of hearing involves the cochlea and cochlear nerve (CN VIII)?
the sensorineural phase
the medial wall of each nasal cavity is formed by the __________ __________
nasal septum
the lateral wall of the nose is formed by the _____________ and their corresponding meatus
turbinates
principle functions of the nose
cleansing, humidification, and temperature control
lies under the tongue; connects tongue to floor of mouth
lingual frenulum
how many teeth does a normal adult have?
32
how many teeth does a normal child have?
20
what three structures form the anterior triangle of the neck?
mandible, sternomastoid muscle, and midline of the neck
what three structures from the posterior triangle of the neck?
sternomastoid muscle, clavicle, and trapezius muscle
muscle that crosses the lower portion of the posterior triangle; can be mistake for lymph node
omohyoid muscle
the great vessels (internal/external jugular, carotid artery) lie just below what muscle?
sternomastoid muscle
hyperopia/presbyopia
farsightedness
myopia
nearsightedness
ex: cerumen (wax), otitis externa, squamous cell carcinoma, perforation of eardrum, cholesteatoma
conductive hearing loss
ex: viruses (rubella and CMV), drugs (ahminoglycosides, loop diuretics), trauma/noise exposure
sensorineural hearing loss
usually associated with upper respiratory infections
sore throat
can be caused by local lesions or systemic illness
sore tongue
caused by diseases of the larynx or extra laryngeal lesions pressing on laryngeal nerves
hoarseness
symptoms: temperature intolerance/sweating, new palpitations or change in weight
thyroid dysfunction
test used to measure visual acuity. pt 20ft from chart, cover an eye and read smallest line
Snellen eye chart
what should you be able to see with an opthalmoscopic exam?
optic disc, retina (arteries, veins, and macula)
what cranial nerve are you testing when you ask the pt to stick out their tongue and observe for symmetry?
CN XII
what cranial nerve are you testing by observing the rise of the soft palate when patient opens mouth and says “ah”?
CN X
clue to a difficult intubation: dry cough
possible tracheobronchial compression
clue to a difficult intubation: easy bleeding
epistaxis risk
clue to a difficult intubation: GERD
aspiration risk
clue to a difficult intubation: longstanding DM
limited cervical mobility
clue to a difficult intubation: loud snoring
prone to soft-tissue obstruction/obstructive sleep apnea
clue to a difficult intubation: major trauma
unstable neck, limited safe mobility
clue to a difficult intubation: radiation to the neck
fibrosis, immobility of larynx
clue to a difficult intubation: recent temporal craniotomy
limited mandibular mobility
clue to a difficult intubation: smoking
salivation, cough, laryngospasm
clue to a difficult intubation: undigested food returning to mouth
aspiration risk from pharyngeal pouch
full visibility of tonsils, uvula and soft palate
mallampati I
visibility of hard and soft palate, upper portion of tonsils and uvula
mallampati II
soft and hard palate and base of the uvula are visible
mallampati III
only hard palate visible
mallampati IV
acceptable thyromental distance
≥ 6cm
acceptable mouth opening
≥ 3cm
definition: increased adrenal cortisol production produces a round “moon” face with red cheeks, also may have excessive hair growth on face
cushing’s syndrome
definition: face is edematous and often pale. swelling first appears around the eyes and in the morning. eyes may become slit like when swelling is severe
nephrotic syndrome
definition: swelling is anterior to earlobes and above angles of jaw (unilateral)
parotid gland enlargement
definition: increased growth hormone production causes enlargement of bone and soft tissues, not the head is elongated usually with prominence of the forehead, nose, lips and ears
acromegally
definition: decreased facial mobility; blunts expression; mask-like faces
parkinson’s disease
drooping of upper lid caused by myasthenia graves, damage to the oculomotor never, or damage to the sympathetic nerve supply = hornet’s syndrome
ptosis
protrusion of the eyeball, a common feature of grave’s disease
exophthalmos
opacities of the lenses visible through the pupil; risk factors: old age, smoking, diabetes, corticosteroid use
cataract
limits based on pupillary reaction
glass eye
a firm, nodular, hypertrophic mass of scar tissue extending beyond the area of injury; common among dark skinned people
keloid
a deposit of uric acid crystals characteristic of chronic tophaceous gout, can appear on ears, joints, hands and feet
tophi
in chronic RA, loof for on the ears, as well as ulna distal to the elbow, knees, and heels
