Q

Functions of the Eustachian Tube:

A
  1. allows air into the middle ear
  2. Equalizes Pressure in the middle ear (d/t altitude)
  3. Drain normal secretions of the middle ear.
  4. Drains secretions into the nasopharynx

Q

Mgmt and HP for otitis externa:

A

Mgmt:

  • topical abx (corisporine otic suspension)
  • pain control w/NSAIDS
  • Wick

HP - decrease moisture in canal

  • gentle use of blow dryer
  • 1:2 mix of vinegar/rubbing alcohol
24
Q

an inflammatory or infectious process that occurs in the middle ear from an accumulation of fluid is likely:

25
Otitis media may result in what forms:
- bacterial - fungal - viral
26
Subjective findings for otitis media:
pain hearing loss stuffiness of ear congestion
27
Chronic congestion /chronic otitis media may potentially cause what in young children
speech delays
28
Objective findings for otitis media:
-decreased /absent mobility of TM is Diagnostic -erythema or bulging of the TM (with obscure landmarks)
29
-Mgmt and HP for otitis media:
Mgmt: - analgesics and auralgen (unless bacterial) - Amoxicillin if 1st line for bacterial HP: -assess each case carefully before RX meds/abx
30
auralgen is
an ear gtt with: - benzocaine (pain) - Antipyrine (an anti-inflammatory) - glycerin (to soften ear wax; protect the ear)
31
what % of otitis media cases are bacterial?
< 25%
32
First line abx therapy for otitis media:
amoxicillin
33
any tear in the integrity of the TM is known as:
TM rupture
34
TM rupture can be caused by
- Trauma - Infection - Neoplasm "TIN for TiM"
35
Subjective findings for TM rupture
pain | hearing loss
36
objective findings for TM rupture
actual tear in the TM
37
Mgmt and HP for TM rupture
Mgmt: - most heal spontaneously unless infx was the cause. - referral for surgical intervention HP: - R/O cholesteatoma formation - monitor hearing function
38
A cholesteatoma is an
abnormal, noncancerous skin growth that can develop in the middle section of your ear, behind the eardrum. It may be a birth defect, but it's most commonly caused by repeated middle ear infections. A cholesteatoma often develops as a cyst, or sac, that sheds layers of old skin
39
$$ Examples of Conductive Hearing Loss:
``` Foreign body Impacted cerumen Infection Cholesteatoma Otitis media Otosclerosis Trauma Tumor ```
40
$$ examples of sensorineural Hearing loss:
``` Acoustic tumor Trauma Congenital or hereditary Infection Meniere’s Ototoxic medications Neurological disorders Presbycusis ```
41
Otosclerosis
is the abnormal growth of bone of the MIDDLE ear. This bone prevents structures within the ear from working properly and causes hearing loss. For some people with otosclerosis, the hearing loss may become severe.
42
Presbycusis
is the most common type of Sensorineural Hearing Loss caused by the natural aging of the auditory system. It occurs gradually and initially affects the ability to hear higher pitched (higher frequency) sounds.
43
For patients with PE tubes, ruptured TM or recent ear surgeries, what otic drops would be a better option for them?
Ciprodex | Otofloxin
44
Pearls for ear examination:
1. look carefully - repeatedly looking improves skills 2. watch for foreign bodies (kids like ears) 3. secure the head of kids during exam to reduce R/O trauma during exam
45
Types of Ear Pain (broadly broken down)
1. Primary - originating within ear STRUCTURES | 2. Secondary - referred to the ear from OTHER REGIONS
46
ear pain referred to the ear from another area is known as
secondary ear pain
47
infections and inflammations of middle and external ear structures and mastoid tissues are considered what type of ear pain?
primary
48
Examples of secondary ear pain
- TMJ (dental and periodontal problems) - sinus/ nasopharyngeal infections - lesions of the tongue - cervical musculoskeletal problems - Neuralgias
49
Name the components of physical ear exam:
1. inspection - general appearance, external ear, inspection of ear w/an otoscope 2. Palpation - each ear separately by pulling the pinna OUT and BACK, and either Up/Down. - apply pressure to the tragus
50
functions of the ear include:
1. interpreting and identifying sound 2. detecting the direction of sound 3. maintaining equilibrium
51
Major parts of the ear include
1. external ear (pinna or auricle & the ear canal 2. middle ear (tympanic cavity) 3. inner ear
52
the hearing process begins here by collecting sound waves and channeling them through the ear canal
external ear
53
This part of the ear contains the structures for balance and hearing through a series of connecting chambers and tubes
the inner ear
54
functions as a conduit for hear and as a regulator of the ventilation pressure
the inner ear
55
undiagnosed ear disorders may contribute to
- poor language development - delayed learning - social isolation - hearing loss - risk for falls - missed dx of respiratory and oral infx's
