COMD 461 Assessment #3

Physiological Tests

100

Describe the left contralateral acoustic reflex pathway.

Left outer ear, left middle ear, left inner ear, left auditory nerve, left cochlear nucleus, right superior olivary complex, right facial nerve, right middle ear.

200

What is ECoG and which disorder is it useful for diagnosis?

Used to determine if the inner ear has an excess of inner ear fluid pressure. Used for Meniere's Disease diagnosis where you expect to observe an abnormally large measurement.

300

This wave of the auditory brainstem response is used to estimate thresholds.

Wave V

400

What would you expect to observe for middle ear pressure values for a Type Ad tympanogram?

Normal -150 to +25.

500

What is the expected acoustic reflex responses for a suspected tumor in the right middle ear?

Right ipsilateral - elevated/absent

Left ipsilateral - within normal limits

Right contralateral - elevated/absent

Left contralateral - within normal limits

Pediatrics

100

This pediatric testing technique allows the child to participate in a game to respond to tones or beeps.

Conditioned Play Audiometry

200

True of False: If a child refers on a hearing screening, they test positive for hearing loss.

False! Refer means that we need to do a comprehensive evaluation of hearing sensitivity to determine if a hearing loss is present.

300

What type of testing method would be most appropriate for a typically developing 4-year-old patient?

Conditioned Play Audiometry (CPA)

400

True or False: In the screening version of DPOAEs used during newborn hearing screenings, the audiologist can determine if a hearing loss is present.

False! We can only determine diagnostic information of the hearing loss from evaluation ABR or pure tone testing.

500

True of False: Children with Down Syndrome are  likely to have sensorineural hearing loss.

False! Children with Down Syndrome are likely to have conductive or mixed hearing losses due to craniofacial anomalies.

Random

100

True or False: Exposure to ototoxic medication in utero is likely to result in a conductive hearing loss.

False! More likely to result in sensorineural hearing loss.

200

Which tests of videonystagmography assess central vestibular function (select all that apply)?

1. Saccadic tracking

2. Smooth pursuit

3. Optokinetics

300

If a patient has a present ipsilateral acoustic reflexes, but absent contralateral reflexes, where is the possible site of lesion?

Intracranial fibers connecting the two ears.

400

This cause of hearing loss in children has no known cause.

Idiopathic

500

True or false: A patient with a tumor in the brainstem nuclei is likely to show normal acoustic decay.

False! Acoustic decay will be affected.
