Chapter 59 Assessment and Management of Patients with Hearing and Balance Disorders
Slide 1: Anatomy of the Ear
External, middle, and inner ear
Extra detail: bone conduction vs air conduction
Eardrum looks pearly gray
Slide 2: Assessment of Hearing and Balance
External inspection, otoscopy
Gross auditory acuity: whisper, Weber, Rinne
tests
Slide 3: Weber and Rinne Tests
Weber test: bone conduction
Rinne test: compares air vs bone conduction
Whisper Test
Otoscopic Examination
Gross Auditory Acuity
Slide 4: Question #1
What does the Weber test assess?
A. Air conduction
B. Bone conduction
C. Air and bone conduction
D. Neither
Answer: B. Bone conduction
Rationale: Weber = bone conduction; Rinne = air vs bone
conduction.
Slide 5: Diagnostic Evaluation
Audiometry – detecting hearing loss most important diagonotic instrument
Pure Tone – Sound Simulation of music tones
Speech Audimetry – spoken word
Tympanogram
Auditory brainstem response
Electronystagmography
EAR WAX buildup and Removal
Platform posturography
Sinusoidal harmonic acceleration
Middle ear endoscopy
Are YOU spinning or is the ROOM
spinning?
Slide 6: Hearing Loss
Ears
other things
↑ with age; 50% over 70 yrs (presbycusis)
Excessive Noise levels
Types:
o Conductive: external/middle ear Otitis Media/Otosclerosis
o Sensorineural: cochlea/vestibulocochlear nerve
o Mixed
o Functional (psychogenic)
Slide 7: Manifestations of Hearing Loss
Tinnitus (ringing) – permanent
Difficulty hearing in groups
Turning up TV volume
Gradual impairment not recognized
Progression → speech deterioration, fatigue, withdrawal, isolation
Slide 8: Communication Guidelines (Hearing Impaired)
Ask preferred communication method
Low-tone, normal voice
Speak slowly, distinctly
Reduce noise
Face patient, get attention, speak into better ear
Use gestures, expressions
Write info or use interpreter if needed
Slide 9: External Ear Disorders #1
Cerumen impaction: irrigation, suction, instrumentation (soften with oil, peroxide)
o Ear wax build up
Foreign bodies: irrigation/suction unless swelling risk; may need OR removal
Slide 10: External Ear Disorders #2
External otitis: bacterial (Staph, Pseudomonas) or fungal (Aspergillus)
o Pain, discharge, edema, erythema, itching, hearing loss, fullness
o Tx: comfort, edema reduction, treat infection; wick may deliver meds
Malignant otitis externa: rare, progressive, skull involvement
Slide 11: Question #2
True/False: Otalgia = fullness or pain in ear.
Answer: True
Rationale: Otalgia = ear fullness/pain. In otitis externa → persistent, nocturnal pain. In otitis media →
pain may lessen if tympanic membrane ruptures.
Slide 12: Middle Ear Disorders #1
Tympanic membrane perforation
Acute otitis media: children; bacterial/viral; pain, fever, hearing loss. Tx: antibiotics,
myringotomy/tympanotomy
Slide 13: Middle Ear Disorders #2
Serous otitis media: fluid without infection
Chronic otitis media: recurrent; damages TM, ossicles, mastoid
Tx: prevent recurrence, tympanoplasty, ossiculoplasty, mastoidectomy
Slide 14: Middle Ear Surgery
Tympanoplasty: TM reconstruction
Ossiculoplasty: ossicle reconstruction with prosthesis
Mastoidectomy: remove diseased bone/mastoid/cholesteatoma
Slide 15: Stapedectomy
For otosclerosis
Slide 16: Mastoid Surgery Assessment
Hx: hearing loss, pain, drainage, vertigo, duration, meds
PE: erythema, edema, lesions, discharge (color/odor)
Review audiogram
Slide 17: Mastoid Surgery Goals
Reduce anxiety
Relieve pain
Prevent infection
Stable/improved hearing
Absence of vertigo/injury
Increased knowledge (disease, surgery, postop care)
Slide 18: Nursing Interventions Post-Mastoid Surgery #1
Reduce anxiety: reinforce teaching, support
Relieve pain: analgesics for discomfort; sharp pain = eustachian opening; throbbing+fever =
infection
Prevent injury: assist ambulation, antiemetics/antivertigo
Slide 19: Nursing Interventions Post-Mastoid Surgery #2
Improve communication/hearing:
o
edema/blood/dressings may impair initially; use strategies from “communicating with
hearing impaired”
Prevent infection:
o monitor signs, administer antibiotics, prevent water entry (showers/hair wash)
o HAND Hygiene
Constant Throbbing pain and fever => Infection
Slide 20: Patient Education Post-Mastoid Surgery
Analgesics, antivertigo meds
Activity restrictions: avoid nose blowing both sides, lifting, straining (↑pressure)
Infection signs/reporting
Safety: call for ambulation help (vertigo)
Follow-up care
Slide 21: Question #3
Which teaching is incorrect post-mastoid surgery?
A. Avoid water in ear
B. Constant throbbing pain = infection
C. Call for ambulation help
D. No activity restrictions
Answer: D. No activity restrictions
Rationale: Patients must avoid pressure changes, water exposure, monitor infection, and restrict
activities.
Slide 22: Inner Ear Disorders #1
Vestibular disorders → fall risk
Dizziness: altered orientation sense
Vertigo: illusion of motion/spinning
Nystagmus: rhythmic eye movement, vestibular dysfunction
Slide 23: Inner Ear Disorders #2
Tinnitus
Labyrinthitis
Benign positional vertigo (BPPV)
Ototoxicity
Acoustic neuroma (CN VIII tumor)
************Slide 24: Ménière Disease ********
Abnormal inner ear fluid balance cause by malabsorption of the endolymphatic sac or
blockage of the endolymphatic duct
Manifestations include triad of symptoms: episodic vertigo, tinnitus, and fluctuating
sensorineural hearing loss. Feeling of pressure, nausea and vomiting
Treatment
Low-sodium diet; 1000 to 1500 mg/day
Meclizine (Antivert); tranquilizers—valium, antiemetics—promethazine, and diuretics
may also be used
Surgical management to eliminate attacks of vertigo; endolymphatic sac
decompression, middle and inner ear perfusion, and vestibular nerve sectioning
Abnormal endolymph balance: sac malabsorption/duct blockage
Triad: episodic vertigo, tinnitus, fluctuating sensorineural loss
Also: pressure, N/V
Tx: low-sodium diet (1000–1500 mg/day), meds (meclizine, valium, promethazine,
diuretics)
Surgical: sac decompression, inner ear perfusion, vestibular nerve section
Slide 25: Question #4
True/False: Cochlear implant = auditory prosthesis for bilateral profound sensorineural loss,
unhelped by hearing aids.
Answer: True
Rationale: Cochlear implant restores hearing in profound sensorineural loss not improved with
conventional aids.
