Flashcards in Exam 4: Assessment and Care of patients with ear and hearing problems (8 questions) Deck (23):
1

Ear Diagnostic testing: Tympanometry

Mobility of the eardrum & middle ear structures

2

Ear Diagnostic testing: Auditory brainstem-evoked response

Electrodes used, detects hearing loss in patients unable to indicate recognition of sound

3

Ear Diagnostic testing: Electronystagmography (ENG)

- Detects central or peripheral disease of the vestibular system
- No Pacemakers
- NPO several hours prior
- No caffeine, alcohol, sedatives, or antihistamines 24 hours prior

4

Ear Diagnostic testing: Caloric testing

Evaluates the vestibular portion of the auditory nerve

5

Ear physical testing: Tympanic membrane

- Right ear: cone of light at the 5 o’clock position
- Left ear: cone of light should be at the 7 o’clock position

6

Age related Ear changes

- Pinna elongated
- Hair in ear canal coarser and longer
- Cerumen drier, can cause impaction
- Tympanic membrane loses elasticity
- Hearing acuity decreases
- High frequency sounds lost first

7

Conductive hearing loss

Physical obstruction of sound wave transmission

8

Sensorineural hearing loss

- Defect in the cochlear or
- The CN VIII or
- The brain (temporal lobe)
- Presbycusis (most common type)

9

Mixed hearing loss

Profound hearing loss
- combination of conductive damage in the outer or middle ear and sensorineural damage in the inner ear (cochlea) or auditory nerve.

10

Tuning fork tests

Weber
- Vibrating tuning fork placed in middle of head

Rinne
- Compares air conduction with hearing to bone conduction

11

Conductive hearing loss treatment (specific name later)

- Surgery
- Bone-conduction hearing aid
- Surgically implanted, osseointegrated device
- Conventional hearing aid
- Antibiotic or antifungal medications (infections)

12

Sensorineural hearing loss medication (specific surgery later)

- Corticosteroids
- Surgery

13

Mixed hearing loss treatment

- Take care of the conductive problem first
- Treat what can be treated

14

Vertigo management

- Positional exercises
- Rest in quiet places

15

Vertigo medication

- Meclizine
- Antiemetics
- Diphenyhydramine, dimenhydrinate
- Scopalamine
- Diazepam

16

Menieres disease patho/etiology

- Vestibular disease due to an excess of endolymphatic fluid
- Distorts the inner-canal system

17

Menieres disease symptoms

Attacks lasting days or continuously
- Tinnitus
- vertigo
- Unilateral sensorineural hearing loss

18

Menieres disease treatment

- Diet
- Fluid
- Medications
- Surgery

19

Hearing loss medical treatment

- Early detection
- Safety measures (due to hearing loss)
- Dietary (nutrition, hydration)
- Medication

20

Hearing loss surgical treatment

- Hearing aids

- Tympanoplasty

- Stapedectomy

- Implants (e.g., cochlear devices)

21

Hearing loss surgical treatment: Tympanoplasty

- Reconstruct the eardrum
- For Conductive hearing loss

22

Hearing loss surgical treatment: Stapedectomy

- surgical procedure of the middle ear performed in order to improve hearing
- Done when otosclerosis present
- Conductive hearing loss

23

Hearing loss surgical treatment: Implants

- Cochlear implant
- Sensorineural hearing loss
