Physiologic Measures
A patient has normal middle ear function, but DPOAEs are absent. Dysfunction of these cochlear cells may explain the finding.
Outer hair cells
This condition involves inflammation or infection of the external auditory canal and may be called swimmer's ear.
Otitis externa
The term used to describe the sensation that you or your surroundings are spinning or moving.
Vertigo
The two possible results for a hearing screening.
Pass or refer
This syndrome commonly presents with sensorineural hearing loss, as well as pigmentation differences like a white forelock.
Waardenburg Syndrome
What three measures are reported in tympanometry?
-Ear canal volume
-Compliance
-Middle ear pressure
This disorder results from abnormal bone growths on the stapes footplate and has a strong genetic component.
Otosclerosis
The name of the reflex that supports stable gaze.
Vestibulo-ocular reflex (VOR)
The two measures that can be used for newborn hearing screening.
DPOAEs (screening version)
ABR (screening version)
The type of tympanogram expected for a patient immediately preceeding otitis media.
Type C
During acoustic reflex testing, this term refers to the setup when the sound is presented and measured in the same ear.
Ipsilateral
This disorder occurs when the cochlea has fewer than 2.5 turns
Mondini malformation
This vestibular structure detects linear acceleration in the horizontal plane.
Utricle
In the 1-3-6 guidelines, what does the 3 stand for?
hearing evaluation by 3 months for children who refer on the hearing screening
A patient has normal bone conduction but air conduction thresholds fall in the moderate range bilaterally. You record Type As tympanograms bilaterally. Name a disorder that could cause this pattern?
Otosclerosis; tympanosclerosis
Less likely
-Otitis media (bilateral)
-Cholesteotoma (bilateral)
This test uses electrodes to record electrical responses to sound without requiring the patient to raise their hand.
ABR
This disorder involves severe vertigo that lasts a few seconds and can be induced with head movement.
BPPV
These sensory structures within the semicircular canals contain hair cells that respond to angular head rotation.
Ampulla
Name three risk factors for pediatric hearing loss.
Low birth weight
Family history of hearing loss
In-utero infection (e.g., cytomegalovirus, rubella, herpes)
Ototoxic medications
Low Apgar scores
Ventilator use for five days or longer
Craniofacial anomalies
Physical abnormalities associated with a syndrome
Bacterial meningitis
Severe jaundice (hyperbilirubinemia)
NICU stay
A patient reports hearing their own breathing unusally loudly. What middle ear structure may not be functioning normally?
These are the middle ear muscles that support an acoustic reflex in a healthy ear.
-Stapedius
-Tensor tympani
This frequency is likely to show a notch in noise-induced hearing loss.
4000 Hz
Peripheral or central
This disorder may pass on newborn hearing screening if DPOAEs are the only measure used.
Auditory Neuropathy Spectrum Disorder (ANSD)
What is one symptom that would dissociate vestibular neuritis from labyrinthitis?
Hearing loss or tinnitus
