ENT Flashcards
1
Q
Meds that affect hearing…
A
- Aminoglycosides
- Aminoglycosides can cause hearing loss, specifically gentamicin
- Aspirin
- NSAIDs
- Quinine
- Furosemide
2
Q
Concerning/Common S&S EARS
A
- Hearing loss: may be congenital, from single-gene mutations
- Distinguish between conductive and sensorineural loss
- Otalgia (earache)
- Otorrhea (discharge)
- Cerumen (wax) normally found in ear
- Tend to be yellowish-dark brown color
- Consistency: sticky
- Falls out of ear on its own or removed w/ washing
- Can build up ⇒ blocks ear canal (wax blockage)
- One of most common causes of hearing loss
- East Asians or Native Americans → usually drier and whitish gray
- Cerumen (wax) normally found in ear
- Tinnitus: common Sx that increases in frequency w/ age
- When associated w/ hearing loss and vertigo ⇒ suggests Meniere Disease
- Vertigo: perception that pt or environment is rotating or spinning
3
Q
Concerning/Common S&S NOSE
A
- Rhinorrhea (runny nose):
- Sneezing, watery eyes, throat discomfort, itchy eyes/nose/throat
- Can be worsened w/ excessive use of decongestants ⇒ causes vasomotor rhinitis
- Environmental triggers or seasonal association ⇒ suggests allergic rhinitis
- Congestion: If pt’s nasal congestion limited to one side ⇒ consider deviated nasal septum, foreign body, or tumor
- Epistaxis (bloody nose):
- Assess if pt on anticoagulation therapy or aspirin bc ⇒ they interfere w/ clotting
- Nasal sprays, if overused ⇒ can contribute to rebound effect ⇒ causing inflammation and congestion
- Change in smell: Loss of smell and taste ⇒ associated w/ COVID-19 infection
4
Q
Concerning/Common S&S THROAT
A
- Hoarseness: Acute hoarseness might be caused by voice overuse or acute viral laryngitis
- Sore tongue: Note findings under tongue– aphthous ulcers or atrophic glossitis
- Bleeding gums: Most often caused by gingivitis: inflammation of gingiva
5
Q
Weber Test
A
- tests lateralization
- Norm: sound is heard equal bilaterally
- In conductive hearing loss ⇒ sound lateralizes to impaired ear
- In unilateral sensorineural hearing loss ⇒ sound heard in good ear
- Restricted to pts w/ unilateral hearing loss bc pts w/ normal hearing may lateralize (hear sound on 1 side) and pts w/ bilateral conductive or sensorineural deficits won’t lateralize
- Steps: place base of lightly vibrating tuning fork on top of pt’s head or mid-forehead → ask where pt hears sound → normally sound heard midline or equally in both ears
6
Q
Rinne Test
A
- compares air and bone conduction
- Norm: air conduction lasts longer than bone conduction (AC > BC)
- In conductive hearing loss ⇒ sound heard thru bone as long as or longer than it is through air (BC = AC or BC > AC)
- In sensorineural hearing loss ⇒ sound heard longer thru air than bone (AC > BC)
- Hearing is decreased in both hearing losses
- Steps: place base of lightly vibrating tuning fork on mastoid bone, behind ear and lvl w/ canal → when pt can’t hear sound anymore place fork close to ear canal → ask pt if vibration is heard
7
Q
Tonsil Grading
A
- 1: tonsils visible
- 2: tonsils between tonsillar pillars and uvula
- 3: tonsils touching uvula
- 4: tonsils touching each other
8
Q
Gag Reflex CN IX and X Test
A
- Tests: gag reflex of CN IX (glossopharyngeal) and X (vagus)
- Steps: palpate palatal arches w/ tongue depressor one at time and wait for normal gag reflex
Abnormal results: - If no gag reflex ⇒ indicates one side of IX glossopharyngeal nerve is damaged
- Soft palate doesn’t rise and uvula deviates to opposite side away from lesion ⇒ indicates damaged X vagus nerve
9
Q
4 MAIN TYPES OF DESCRIBED DIZZINESS
A
- Vertigo
- Strong sense of motion or spinning
- Can be peripheral or central
- Disequilibrium
- Common: pts have it temporarily or infrequently
- Feeling off-balance
- Unsteady / Wobbly
- Lightheadedness
- Woozy
- Disconnected from environment
- Presyncope
- Feeling of losing consciousness
- About to faint
10
Q
Peripheral Vertigo General Info
A
- Onset: Sudden
- Intermittent w/ severe Sxs
- Affected by head position and movement
- NV more frequent
- Motor function, coordination, gait intact
- Causes: less severe
11
Q
Central Vertigo General Info
A
- Onset: Gradual
- Constant w/ milder Sxs
- Unaffected by head position and movement
- NV less frequent
- Motor function, loss of coordination, gait instability frequent
- Causes: more severe
- Duration: variable but rarely continuous
- Hearing: unaffected
- Tinnitus: absent
- Additional features: usually w/ other brainstem deficits– dysarthria, ataxia, crossed motor and sensory deficits
12
Q
Peripheral Vertigo: Meniere Disease
A
- Onset: sudden
- Duration: several hrs – ≥1 day
- Hearing: sensorineural hearing loss– recurs, eventually progresses
- Tinnitus: present, fluctuating
- Additional features: pressure or fullness in affected ear, NV, nystagmus
13
Q
Otitis Media (what, cause, common in, identified during which tests)
A
- What: inflammation of middle ear (Classified as primary otalgia (ear pain))
- Cause: bacterial infection
- More common in children than adults
- Tested/Identified during:
- Conductive vs. neurosensory hearing loss w/ Tuning Fork Test
- This is unilateral conductive hearing loss → sound heard in/lateralized to impaired ear
- Palpation of Tragus and Pinna
- Pt feels pain during palpation
- Conductive vs. neurosensory hearing loss w/ Tuning Fork Test
14
Q
Otitis Media S&S
A
- Serous effusion, thickened drum, purulent otitis media ⇒ can decrease mobility
- With any perforation ⇒ there’ll be no mobility
- Tenderness behind hear
- Might see distorted light reflex
- Can’t see landmarks of ossicles bc tympanic membrane or eardrum is bulging
- Bulges laterally toward examiner’s eye
- Red bulging drum ⇒ indicates purulent otitis media
- May have drainage behind eardrum
- Dilated blood vessels can be seen in all segments of drum
- Diffuse redness of entire eardrum may follow w/ discharge of purulent material to ear canal
- Earache
- Fever
- Hearing loss
15
Q
Otitis Externa / “Swimmer’s Ear”
A
- What: inflammation of ear canal/outer ear (Classified as primary otalgia (ear pain))
- Cause: frequent submersion of ear in water
- Tested/Identified during: External Meatus Patency when pulling ear up to look at canal → painful for pt
- S&S:
- Ear canal is swollen, tender, narrowed, moist, pale, and/or reddened
- If chronic, skin canal thickened, red, itchy
- Pt feels pain if you put otoscope in or if you pull ear up
- Hearing loss
- Drainage
- Swelling
- Edema
- Erythema
- Pain
