Objectives
• Discuss major inflammatory, infectious and noninfectious disorders of the ear
• Discuss med-surg management• Discuss nursing management• Client education
Hearing Impairment
• A state of decreased auditory acuity that ranges from partial to complete hearing loss
Types of Hearing Loss
• Conductive hearing loss – Interference with the transmission of sound
waves from the external or middle ear to the inner ear http://www.youtube.com/watch?v=QE1AyH-uq9s
• Sensorineural hearing loss – Disturbance of the neural structures in the inner
ear or the nerve pathways to the brain
• Mixed hearing loss – A combination of conductive and sensorineural
losses http://www.youtube.com/watch?v=suPmtVNKpck
Types of Hearing Loss• Congenital hearing loss
– Can happen during pregnancy or delivery• Syphilis or Rubella exposure• Rh incompatibility • Anoxia or trauma during delivery• Ototoxic drugs
• Functional hearing loss– No organic cause– Also called psychogenic or nonorganic hearing loss
• Central hearing loss – Problem in the central nervous system– The brain’s auditory pathways are damaged as in a stroke
Loss of Hearing (Deafness)– Clinical manifestations/assessment
• Requests for repeating information• Non-response• Delayed speech development
– Assessment• S: note onset and progression of the condition; deficit in
one or both ears; family hx. or hx. of head trauma; exposure to noise, current medications, visual or speech disorders
• O: behavioral clues that indicate hearing difficulty– P. 631 Box 13-2
Behavioral Clues Indicating Hearing Loss
• Complaints that their hearing is good but others mumble
• Leaning or turning one ear toward the speaker • May fail to follow directions, speak while others are
speaking, or turn the radio/TV up very loud• Irritability and even hostility not unusual • Some become very suspicious of others because
they cannot hear what is being said • Otalgia (ear pain), dizziness, and tinnitus with
certain types of disorders
Loss of Hearing (Deafness)
• Diagnostic Tests: – Weber’s Test– Rinne Test– Audiometric Testing
• Nursing Responsibilities– Explain the purpose of and the procedure

Loss of Hearing (Deafness)
• Medical management• According to the type of impairment
– Hearing aids– Surgical procedures
» Cochlear implant

Loss of Hearing (Deafness)• Nursing Interventions:
– Instruct in insertion and care of hearing aid• p. 634 Box 13-3 Care of the Hearing Aid
• Nursing Diagnoses include: • Disturbed Sensory Perception AEB frequently asking
people to repeat themselves (auditory) related to new dx. of hearing impairment
• Social isolation related to loss of hearing

Loss of Hearing (Deafness)
• Prognosis: • Some restoration of hearing with surgical repair• Microtechnology has reduced size of hearing aids
Presbycusis• Hearing loss associated with aging • Gradual atrophy of the sensory receptors and
cochlear nerve fibers
• Signs and symptoms – May hear well in quiet surroundings but poorly in
noisy places– Ability to hear high pitched sounds is usually lost
first
Presbycusis
• Medical Diagnosis and Treatment – Hearing evaluation for the older person whose
hearing seems to be declining– Many with presbycusis benefit from hearing aids– Devices available to improve hearing: phone
amplifiers and personal earphones for radios and televisions

Impact of Hearing Impairment
• Those who had impairments in early childhood usually have speech difficulties
• When a person refuses to admit to hearing loss,
family members and others may stop trying to communicate
• Hearing-impaired person may alienate those who would like to be close and supportive
Impact of Hearing Impairment
• People with severe hearing impairment probably suffer the most severe social isolation of those with sensory disorders
Adaptations to Hearing Loss
• Hearing aids—some improvement in hearing
• Many patients read lips and observe body language • Sign language uses a universal set of hand signals (wrong)
• Telephones can be adapted to send and receive written messages
• Earphones for radios, stereos, and televisions
Adaptations to Hearing Loss
• Some television channels provide closed-captioned programming
• Handheld computers print out messages typed by the user
• Dogs are taught to recognize common sounds (doorbell, telephone, smoke alarm, crying baby) and to get the attention of the owner
Nursing Care
• Educate pt. about hearing loss and aging
• Work to overcome the resistance that many people have to admitting hearing loss
• Once problem diagnosed, nurses can help the patient adapt and learn to use supportive devices
Nursing Care
• Nursing diagnoses: (r/t, AEB)– Impaired Verbal Communication – Social Isolation – Ineffective Coping – Deficient Knowledge
External Otitis
• Etiology/pathophysiology– Inflammation or infection of the external canal or
the auricle of the external ear
– Sometimes called “swimmer’s ear”
– More present in hot, humid weather
– Can be caused by allergy, bacteria, fungi, viruses, and trauma
External Otitis• Etiology/Pathophysiology
– Chemicals in hairsprays, cosmetics, hearing aids, and medications as well as from nickel or chromium in earrings can cause allergies external otitis
– Bacterial agents include: Staph Aureus, Pseudomonas A. and Streptococcus pyogenes
External Otitis Herpes .
Simplex
• Etiology / Pathophysiology– Viruses include herpes simplex and h. zoster– Fungi such as Aspergillus and Candida– Trauma from cleaning or scratching the ear canal with a
foreign object– Dry hard cerumen difficult removal external otitis– Activities that allow moisture to become trapped in the
ear creating a medium for bacteria to grow on:• Use of earphones, hearing aids, stethoscopes
External Otitis
– Clinical manifestations/assessment• Pain with movement of auricle or chewing• Erythema, scaling, pruritus, edema, watery discharge,
and crusting of the external ear• Drainage may be purulent or serosanquinous
– Pseudomonas: green, musty-smelling drainage
– Assessment: pain assessment; drainage assessment; home remedies used; presence of edema
Fungal infection
External Otitis
– Diagnostic Tests: Culture and Sensitivity of drainage
– Medical Management• Oral analgesics; corticosteroids• Antibiotic or antifungal ear drops; oral antibiotics• Specific antibiotic will be based on the culture results
– Nursing interventions: cleansing of ear canal; poss. heat for pain relief; instill ear drops; adequate method of communication
Acute Otitis Media• Middle Ear Infection
• Most often caused by: H. Influenza & Strep pneumoniae
• Occurs frequently in children 6-36 mo. old and in the winter and early spring– Children’s shorter and straighter eustachian tubes
provide easier access of microorganisms from the nasopharynx middle ear.
• Often post URI
Acute Otitis Media
• Clinical Manifestations:– Sense of fullness in the ear– Severe, deep throbbing pain behind the tympanic
membrane (pain may disappear if TM ruptures)– Hearing loss, tinnitus (ringing, tinkling), and fever may
develop
• Assessment– See External Otitis
• Diagnostic Tests: culture of purulent drainage
Acute Otitis Media
• Medical treatment – Oral antibiotics – Analgesics– Topical ear drops – Antihistamines – Myringotomy (small incision in the eardrum to
drain fluid and relieve pressure)– Tympanostomy tube placement for long- or
short-term use
Acute Otitis Media
• Nursing Interventions– Medication Instructions– If hearing loss, effective communication– Children are to be fed upright to prevent
nasopharyngeal flora from entering the eustachian tube
– Instruct to blow nose gently– If myringotomy performed, instruct parents to
change the cotton in the outer ear 2x/day
Acute Otitis Media
• Mastoiditis: an infection of one of the mastoid bones.– Usually an extension of a middle-ear infection that
was untreated or inadequately treated
– S/S: earache, headache, fever, large amts of purulent exudate, malaise

Chronic Otitis Media
• Eardrum may be permanently perforated (ruptured) or shows signs of a healed perforation with chronic fluid trapped behind it
• There may be intermittent drainage
• Possible complications of chronic otitis media include mastoiditis, meningitis, labyrinthitis, cholesteatoma, and hearing impairment
What should the nurse advise the 20-year-old to do who has been put on cefaclor (Ceclor) for a resistant otitis media?
a. Store suspension at room temperature
b. Discontinue drug when symptoms abate
c. Avoid alcoholic beverages
d. Take with meals only
19.ANS: Cc. Avoid alcoholic beverages
Drinking alcohol is discouraged while on Ceclor. The drug should be taken in its entirety and stored in the refrigerator. The drug can be taken with or without meals. PTS: 1 DIF: Cognitive Level: Knowledge REF: Page 657, Table 13-5OBJ: 16 TOP: Ceclor KEY: Nursing Process Step: ImplementationMSC: NCLEX: Physiological Integrity
Chronic Otitis Media
• Medical treatment – Systemic antibiotics and, if the eardrum is intact,
irrigations to remove debris – Tympanoplasty if tympanic membrane does not
heal– Mastoidectomy if the infection has extended to
the mastoid bone
Labyrinthitis
• Inflammation of the labyrinthine canals of the inner ear
• Acute labyrinthitis usually follows an acute upper
respiratory infection, acute otitis media, pneumonia, or influenza
• Also can be an adverse effect of drugs – e.g. Streptomycin can destroy the vestibular portion of the inner ear
Labyrinthitis
• Another type: suppurative (pus) labyrinthitis – Inner ear infection that usually follows an upper
respiratory infection, ear infection, or ear surgery
– The effects can destroy the labyrinth and cochlea, causing permanent deafness
Labyrinthitis
• Signs and symptoms – Sudden and severe vertigo, nausea, vomiting,
headache, anorexia, nystagmus, photophobia, ataxic gait
• Assessment: note frequency and duration of vertigo; safety measures taken; hearing ability, ringing in ears, nausea; jerking movements of eyes, color and moisture of skin.
Labyrinthitis• Medical treatment
– Anti-emetics and supportive care until it resolves – Antibiotics if infection is present– Dramamine or Meclizine for vertigo
• Nursing Diagnosis: – Risk for injury r/t altered sensory perception
(vertigo)– Fear r/t altered sensory perception (vertigo)
Labyrinthitis
• Nursing care– Assess symptoms – Monitor intake and output, daily weights if
possible, and food intake if persistent vomiting – Assist/supervise the patient when out of bed– Give antiemetics as prescribed– Instruct and monitor safety measures
Obstructions of the Ear
• Etiology/pathophysiology• Impaction of cerumen in canal; foreign bodies
• Clinical manifestations• Tinnitus and pain in the ear• Slight hearing loss; tugging at ear
• Assessment• Pt. interview re: possibility of foreign body, home
remedies used; note presence of foreign body
• Diagnostic Tests: Otoscope exam
Obstructions of the Ear
– Medical Management• Removal of cerumen by irrigation
– Carbamide (Debrox) peroxide to soften cerumen
• Foreign objects are removed with forceps• Insects are smothered with drops of oily
substance and removed with forceps• Possible surgical removal of the foreign object
Foreign Bodies and Cerumen
• Impacted cerumen is the most common causes of obstruction– Physician may order ear drops to soften the
cerumen before irrigation – Physician can use ear forceps or a cerumen
spoon to remove it
Obstructions of the Ear
• Nursing Interventions– During assessment – note the presence and
amount of hearing impairment– Otoscope exam– Ear irrigations– Reassure pt. of return of hearing after obstruction
removed• Nursing Diagnosis: Disturbed sensory perception
(auditory) r/t presence of foreign body causing obstruction
Otosclerosis
• Etiology/pathophysiology– Chronic, progressive deafness due to formation of
spongy bone, especially around the oval window with resulting immobility of joint of the stapes tinnitus and then deafness
– Fixed stapes cannot vibrate, so sound waves cannot be transmitted to inner ear
– Effect is a conductive hearing loss– Most common in young Caucasian women
Otosclerosis
– Clinical manifestations/assessment• Slowly progressive conductive hearing loss• Low medium pitched tinnitus• Deafness will first be noted between ages 11
and 20• Presence of mild dizziness vertigo• Assess family hx of same
Otosclerosis
– Diagnostic Tests: • Otoscope: Schwartz’ sign – a pink blush in the ear• Rinne’s Test, Weber’s test, Audiometric testing,
tympanometry
– Medical Management• Stapedectomy• Air conduction hearing aid
Otosclerosis
– Nursing Interventions• Post Stapedectomy Care per usual post ear surgery
care– External ear packing – leave in place 5-6 days– Bedrest x 24 hrs– Keep flat with operative ear up (to maintain the placement of
the prosthesis)– NO turning– Tx. Headache, dizziness
• Review P. 644 “After Ear Surgery”
Meniere’s Disease
• Etiology/pathophysiology– Chronic disease of the inner ear– Recurrent episodes of vertigo unilateral
progressive nerve deafness, and tinnitus– Increase in endolymph fluid( increased pressure in
the inner ear)– The cause is unknown– Attack triggers: alcohol, nicotine, stress, and certain
stimuli such as bright lights and sudden movements of the head
Meniere’s Disease
• Clinical manifestations/assessment• Vertigo (recurrent) – often preceded by sense of
fullness and pressure in the ear • Nausea and vomiting• Hearing loss – unilateral; repeated attacks can lead to
permanent senorineural hearing loss• Tinnitus• Diaphoresis• Nystagmus
Ménière’s Disease
• Assessment– Document pattern of acute attacks – Note substances/stimuli that trigger episodes – Specific symptoms including nausea, vomiting,
vertigo, and tinnitus – Determine how the condition affects the
patient’s life, what the patient knows about the disease, and coping mechanisms
Ménière’s Disease
• Medical Diagnosis – Diagnosed by ruling out other conditions that
can cause similar symptoms – e.g. CNS disease– Physician likely to order a number of radiographs
and other tests to detect any neurologic, allergic, or endocrine disorders
– Audiogram, Vestibular testing, Glycerol test
Meniere’s Disease• Medical management
• No specific treatment
• Decrease fluid pressure– Fluid restriction; diuretics; low-salt diet
• Avoid caffeine and nicotine
• Dramamine, meclizine, and Benadryl – use between attacks
• Meds may be given IV during acute attacks
Meniere’s Disease
• Medical Management cont.• Surgical Procedures are for preservation of
hearing
• See Table 13-7 p. 644 AHN for surgeries and post op nursing interventions
Meniere’s Disease
• Nursing Interventions• Maintain the prescribed low-salt diet• Administer diuretics• Acute vertigo: bedrest, sedation, antiemetics• Provide effective means of communication• Safety• Patient Education
• Review: Patient Teaching “Vertigo” p.640
Ménière’s Disease
• Nursing Diagnosis: (r/t, AEB)– Risk for Injury – Risk for Deficient Fluid Volume – Anxiety – Ineffective Therapeutic Regimen Management
Ménière’s Disease
• Postoperative care– Carefully check physician’s orders for position and
activity limitations
– Safety, comfort, and detection of complications – Antiemetics to control nausea and vomiting – No nonessential care until patient tolerates movement
Ménière’s Disease
• Post Operative Care cont.– Assist patients when getting up and walking – Call button should always be within reach; patients may be
dizzy for several days, unsteady for several weeks
– Assess for facial nerve damage
Ototoxicity
• Damage to the ear or eighth cranial nerve caused by specific chemicals, including some drugs
• Common ototoxic drugs are salicylates (aspirin) and aminoglycoside antibiotics
• From reversible tinnitus to permanent hearing loss
Ototoxicity
• The primary symptom of ototoxicity with salicylates is tinnitus, which disappears when the drug is discontinued – Extent depends on dosage and how long it was given
• Patients who have poor renal function are at special risk for ototoxicity because drugs are excreted more slowly
Ototoxicity
• Nursing care– Primary are early detection and prevention of
progressive hearing loss caused by ototoxic drugs – To reduce risk of ototoxicity, be familiar with these drugs.
Instruct patients to report hearing loss, tinnitus, or problems with balance
– Promptly report such symptoms to the physician
– Teach patients that aspirin is not a harmless drug
Ototoxicity
• Nursing Care– Monitor urine output of patients on ototoxic
drugs: low output may mean the drug is excreted slowly, increasing risk of toxicity
– Report low urine output to the physician
– Care plan should alert all staff to potential for ototoxicity
Surgeries of the Ear
• Stapedectomy– Removal of the stapes of the middle ear– To restore hearing in the treatment of otosclerosis
• Tympanoplasty– Operative procedures on the eardrum or ossicles of the
middle ear to restore hearing
• Myringotomy– Surgical incision of the eardrum– To relieve pressure and release purulent exudate fron the
middle ear
Post Op Mastoidectomy
• After surgery on the middle ear: comfort, safety, prevention of infection, and prevention of pressure on the tympanic membrane
• Nausea common • Inspect the dressing and describe drainage but do not
disturb or remove the dressing
• Assist patient first time out of bed, in case of dizziness • Patient should avoid activity that creates pressure on the
tympanic membrane (blowing the nose, coughing, sneezing, straining)
Post Op Stapedectomy
• After surgery, pain relief, safety, prevention of infection, and avoidance of pressure in the ear
• Especially important that the patient not do anything that increases pressure in the ear
• Nausea, vomiting, and vertigo are common
• The packing in the ear should not be disturbed
Post Op Stapedectomy
• After dressing and packing removed, patient advised to keep the ear dry for at least 2 weeks
• Swimming and showering not permitted for 6 weeks
• The patient should avoid contact with people who have colds. A balanced diet and adequate rest are needed for tissue healing and resistance to infection
General: Care of the Patient Having Ear Surgery
• Assessment– In postoperative period, pain, nausea, dizziness,
fever – Inspect the wound dressing for drainage – Drainage color, odor, and amount
• Nsg. Interventions:– Pain management – Safety– Reduce risk for Infection – Disturbed Sensory Perception
