Q

What are the layers of the TM?

A

1) Outer epithelial layer (we see this layer during otoscopy, this part comes off and starts to migrate down the EAC)
2) Fibrous middle layer (very strong drum, but won’t be as strong if its compromised through a tube or perf)
3) Inner Mucosal layer (faces the ME space)

54
Q

What is cerumen and why do we have it?

A
  • Cerumen (also commonly referred to as “earwax”) is a naturally occurring bi-product of the ear which exists to clean, protect, and lubricate the external auditory canal
  • Most often, cerumen is harmless (a little bit of cerumen is good for the ear)
55
Q

What three things can happen if there is too much cerumen?

A

When cerumen blocks the ear, or effects the delivery of sound to the ear (i.e. through the use of a hearing aid) it can be problematic
- Prevent thorough examination/interfere with diagnostics
- Cause itching, irritation, otalgia, sensation of fullness
- Can be odorous/can block the ear from proper ventilation

56
Q

Cerumen is made in the ____ portion and can get pushed into the ____ portion

A

Cartilaginous, bony

57
Q

If the cerumen if shiny it is usually ____
The less shiny the cerumen is, the ____ it is

A

Softer, dryer

58
Q

How is cerumen made?

A
  • Mixture of secretions from ceruminous and sebaceous glands
  • Products of the ceruminous and sebaceous glands combine with skin and debris (such as hair cells)
59
Q

Explain the ceruminous glands

A

Ceruminous Glands
- Modified apocrine sweat glands
- Secrete milky white substance that turns to brown when exposed to air (oxidation)

60
Q

Explain the sebaceous glands

A

Sebaceous Glands
- Secrete sebum which is made up of triglycerides

61
Q

Why do we produce cerumen?

A
  • Cerumen is protective to the first portion of our auditory system
  • Hydrophobic, waxy, provides physical protection, and a microbial defence for the external auditory canal
  • Antibacterial and antifungal properties helps to maintain a slightly acidic environment within the ear canal
62
Q

What happens the more you clear your ears?

A

he more wax will be produced

63
Q

Where is cerumen produced? How does it exit the EAC?

A
  • Cerumen in produced in the outer two-thirds of the ear canal (cartilaginous portion) and is
    normally eliminated through a self-cleaning system within the external auditory canal
  • Skin tissue (epithelial tissue) naturally migrates out of the ear and with assistance from jaw movement, carries cerumen and sloughed skin cells with it
  • Accumulation of cerumen can occur when this mechanism is not working effectively, or another factor may be interfering with this process.
64
Q

Skin/epithelial migration ____mm – ____mm per day

A

0.05, 0.07

65
Q

What else could effect the migration of cerumen out of the ear?

A

Health, age, HA use, sleep plugs, ear plugs, air pods

66
Q

Who may have issues with cerumen?

A

Patients seeking assistance for cerumen accumulation is one of the most common reasons patients look to have assistance with their ears

67
Q

Excessive or impacted cerumen effects….

A
  • 1 in 10 children
  • 1 in 20 adults
  • More than one third of the geriatric and developmentally delayed population
68
Q

When does cerumen accumulation occur?

A
  • Accumulation of cerumen can occur when the self-cleaning mechanism is not working effectively, or another factor may be interfering with this process.
  • May be symptomatic or asymptomatic
69
Q

What are the 3 causes for cerumen accumulation?

A

1) Overproduction: Rate of cerumen being produced exceeds the rate of cerumen migrated out of the ear canal
2) Obstruction: Growth in the ear, narrow canals, difficult shapes of canals, soft tissue malformations Objects inserted into the ear canals can influence the migration of debris out of the canals
3) Inadequate Epithelial Migration: Changes over time

70
Q

What happens as we age?

A
  • As we age, cerumen glands change in functioning, and become less numerous.
  • This can result in drier cerumen, and is less easily carried out of the canal with the migration of skin cells.
  • Coarser hair in the canal as part of the aging process can continue to impact the ability for debris to move out of the ear canal
71
Q

What is cerumen impaction? What does it prevent?

A
  • Impaction suggests that debris is lodged, wedged, or firmly packed in the ear canal.
  • Prevents an assessment of the ear canal, tympanic membrane (and possibly beyond).
72
Q

What is cerumen with complete obstruction?

A

Can be associated with a complete blockage of the ear canal, and present with other symptoms reported by the patient

73
Q

Explain the colour and consistency of cerumen

A
  • Color may be effected by other debris or the process of oxidation (and time in canal)
  • Consistency in hardness can be due to dryness (another indication of time in ear canal)
74
Q

What are the 2 types of cerumen?

A

Wet and Dry cerumen (wet is a dominant phenotype)

75
Q

Asian/Eastern Descent cerumen is ____

A

Dry/Flakey

76
Q

African Descent cerumen is ____

A

Soft, “honey-like” consistency

77
Q

European Descent cerumen is ____

A

Soft, sticky consistency

78
Q

What is this?

A

Dry epithelial tissue
- When you see this, think of it as a hang nail (when you pull it off you will see redness)
- May be attached to epithelial tissue that isn’t ready to come off

79
Q

What 5 reasons would we consider removing cerumen?

A

1) Prevents thorough audiological examination/interfere with diagnostics
2) Prevents the ability to perform REMs
3) Prevents the ability for hearing aids to be effective (sound delivery)
4) Will cause impaction in future
5) When requested by patient

80
Q

What are 4 technical aspects of cerumen?

82
Q

What are 5 tools for mechanical CM removal? Which one should you work with?

A

Curettes
1) Buck
2) Billeau
3) Shapleigh
4) Lucae
5) Day
- Work with the smallest curette that will allow you to take the wax out effectively (less of a chance of touching the EAC)
- These are reusable with sterilization

83
Q

Is there a single use option for mechanical removal that does not require sterilization?

A
  • Yes
  • These have a bend to them that the metal ones don’t have (more comfortable if you accidently touch the EAC)
84
Q

What are 3 other options for mechanical removal?

A

1) light source (with magnifier)
2) cork screw type thing
3) alligator forceps (to grab)

85
Q

When to use mechanical removal methods

A

Generally, mechanical removal methods can used to clear partially or completely occluded canals

86
Q

The choice of mechanical removal will depend on what 3 things?

A

1) Shape/size of curette and ear canal
2) Degree of impaction
3) Consistency of cerumen

87
Q

What are 8 guidelines for mechanical CM?

A

1) Stay in the cerumen, stay off the skin
2) No leveraging, scraping, peeling, sweeping!
3) Identify the point of least resistance to take the most cerumen out with as little irritation as possible
4) Attempt to removal cerumen from a more medial point when safe to do so
5) Attempt to place the tip of the tool slightly behind the cerumen
6) SLOWLY move instrument down and out of canal
7) Clean tool in-between passes
8) Speculum may be used for enhanced visualization

88
Q

When would you use a Buck and/or Billeau?

A

scooping out or moving through cerumen impaction

89
Q

When would you use a Lucae and/or Day?

A

Getting behind debris, and pulling to dislodge

90
Q

When would you use forceps?

A

Grabbing dry wax that is not plugged or removing other foreign objects (such as domes, ends of cotton swabs, etc.)

91
Q

What should you do if a problem arises during CM?

A

Pause, reassess, and stop procedure if safety is compromised
- Need to be aware of proximity to the TM
- If the tissue of the canal is being damaged, procedure should be stopped
- If the blockage cannot be removed safely, the procedure should be stopped
- Reassess method, consider additional tools, or refer out

92
Q

How does irrigation remove cerumen?

A

Irrigation removal of cerumen involves flushing the ear with water, that dislodges the cerumen, ideally in fragments, and forces it out of the ear canal

93
Q

When to use irrigation for CM?

A
  • These tools move water through the EAC
  • To do this, we have to know the integrity of the TM (100% need to know if there is a perf)
  • A tympanogram is needed before doing this
94
Q

What 3 things do you need for irrigation?

A

1) Draping
2) Basin
3) Water temperature

95
Q

What is the correct water temperature for irrigation?

A
  • Cold water = painful and makes you dizzy
  • Hot water = can be too hot and painful
  • Anywhere between 37-40 degrees (or lukewarm)
96
Q

4 guidlines for CM through irrigation

A

1) The integrity of the TM MUST BE KNOWN for this method. An intact TM is CRUCIAL. TM perforations are absolutely contraindicated.
2) The stream of water should not be directed directly towards the TM
3) The lowest effective amount of pressure should be used (high pressure has more potential risks)
4) Identify if the cerumen is soft enough to remove with water irrigation (a softer wax will do better with irrigation)

97
Q

How does suction CM work?

A
  • More suction when you cover up the hole
  • No suction when the hole is open
98
Q

Should you use suction on patients with tinnitus?

A

Do not use suction for patients that have tinnitus (do not want to increase the tinnitus by putting another loud sound in the ear)

99
Q

When should you use a suction approach?

A

When the wax is more viscous (wet/runny) suctioning may be a good option for removal

100
Q

What are the 6 steps of using suction for CM?

A

1) Place the tip of the suction at the top of the impaction
2) Place your finger over the small hole in the suction tip
3) Orient the tip slightly down and pull out of the ear canal
4) Stay on the cerumen
5) Stay off the ear
6) Patients need to be counselled that this can be very loud

101
Q

Infection control for CM must include what 3 things?

A

1) Use of barriers (gloves minimally) consider donning and face shields
2) Use of clean tools
3) Used on clean surfaces

102
Q

Treat any cerumen as it is ____

A

Infectious

103
Q

When is cerumen considered infectious?

A

Cerumen is considered infectious if it contains blood, ear discharge or mucous, but this is not always clear through otoscopy

104
Q

What happens if you come in contact with infectious cerumen?

A

1) CLEANING: Soap in sink
2) Disinfecting: Ultrasonic Cleaner or disinfectant wipe
3) Sterilization: 100% germs are destroyed (cold or hot)

105
Q

What requires sterilization for the suction pump?

A
  • Glass Collection Jar – does not require sterilization
  • Plastic tubing – does not require sterilization
  • Metal suction tip – cold sterilant
  • Glass jar for water – cold sterilant
106
Q

What requires sterilization with curettes?

A
  • Plastic – disposable
  • Metal – cold sterilant
107
Q

What requires sterilization with a specula?

A

Plastic – cold sterilant

108
Q

How do we soften cerumen in the EAC?

A
  • Cerumenolytic agents are compounds used to break down impacted cerumen to lessen the need for irrigation or manual removal
  • Cerumenolytics can also be used in combination with other cerumen management strategies
  • No one cerumenolytic has been proven to be more effective another agents
  • Oil-based, peroxide-based, water-based
109
Q

Who are cerumenolytics limited to?

A

patients with intact tympanic membranes, without active dermatitis, or infection of the ear canal

110
Q

When do you need to counsel for the use of cerumenolytics?

A

1) Counselling for at home use
2) Counselling in clinic
3) Counselling with use of hearing aid (time of day matters; do it at night when you aren’t wearing a HA. We don’t want the HA to be sitting in the wet, cerumenolytic)

111
Q

Explain ear candling

A
  • can get burns from the hot wax dripping into the EAC
  • more soot and debris is going into the ear rather than the cerumen being pulled out
112
Q

Why do we need informed consent for CM?

A

Patients must be fully informed of the risks, reasons, and potential benefits of cerumen management (not just the “what”, but the “why”)

113
Q

True informed consent outlines the need to inform patients of what 6 things?

A

1) Nature of treatment
