Two types of hearing loss
|
Conductive and Sensorineural
|
|
Pathologics for Conductive HL
|
External and Middle Ear
|
|
Pathologics for Sensorineural HL
|
Cochlea/Cochlea N. and Brain Stem
|
|
(HL) Loudness of Speech
Conductive vs. Sensorineural |
Conductive = Softer
Sensorineural = Louder |
|
(HL) Impaired
Conductive vs. Sensorineural |
C = Air conduction
S = Air and Bone conduction |
|
(HL) Rinne
Conductive vs. Sensorineural |
C = Negative
S = Positive |
|
(HL) Weber
Conductive vs. Sensorineural |
C = Heard on "deaf side"
S = Heard on better side |
|
Congenital deafness accounts for ____ of all deafness in ______.
|
50%
Children |
|
Formation of new bone in the labyrinth, and causes fixation of stapes to ______ window.
Also found in what type of HL? |
Otosclerosis
Oval Conductive |
|
With the exception of _______, conductive HL alters appearance of ______?
|
Otosclerosis
Tympanic Membrane |
|
Causes of Vertigo and frequently assoc w/ ?
|
Assoc with a loss of vestibular fxn (unsteady gate)
Results from: (IMNOP) Iatrogenic Menier's ds: causes severe paroxysmal vertigo from labyrinthine lesions Neurologic Otologic Psychological |
|
Clinical triad for Meniere's Syndrome
|
Vertigo w/ vomiting
Tinnitus HL |
|
What is Otalgia?
What are the Localized causes? |
Ear Pain
Otitis Externa (Swimmers ear) Otitis Media |
|
What is Otalgia?
What are the Referred causes? |
Ear Pain
Teeth, TMJ, cervicals (C2-3), pharynx (mucosal swelling) Inflammation, trauma, or neoplasm anywhere along C.N. V, VII, IX, X -Present in ipsilateral ear and is referred |
|
What is tinnitus and what might cause it?
|
The sensation of hearing sound, such as buzzing or ringing, in the absence of environmental input.
It is assoc w/ a conductive or sensorineural hearing loss |
|
What are causes for nodules in and around the ear?
|
Tophi (from gout) on helix or antihelix
Carcinoma & hematomas Scar tissue from trauma (piercing) |
|
Differences between examining the inner ear of a child vs. an adult
|
Access the external auditory canal, tympanic membrane, malleus
Adults = pull Posterior and Superior Child = pull Posterior and Inferior |
|
Features of the normal tympanic membrane
|
Intact, ovoid, semitransparent, pearly gray membrane
-Ds will be yellow or red "Light reflex" should be AnterioInferior of pars tensa Long process of the incus is usually posterior to the malleus |
|
How is patency of the Eustachian tube determined?
|
Obstructed eustacian tube moves inward = Retract
Fluid in the middle ear will have decreased or absence of movt = Bulging |
|
S/S for Acute Otitis Externa
|
-Swimmers ear
-Painful when pulling on tragus and auricle -Inflammation of external canal but NORMAL tympanic membrane -Yellowish-green discharge |
|
S/S for Acute Otitis Media (aka Baterial)
|
-Primary in children
-No pain when pulling on auricle and tragus -Tympanic membrane is fiery red and BULGING outward |
|
S/S for Secretory Otitis Media
|
-Primary in ADULTS
-Air becomes trapped w/in middle ear (air bubble); tympanic membrane will RETRACT -Amber color |
|
Weber Test
|
Compares BONE conduction in BOTH ears
(512 MHz) |
|
Rinne Test
|
Compares AIR and BONE conduction separately
(512 MHz) |
|
Rinne Positive test
|
AC > BC (Normal or Sensorineural los)
|
|
Rinne Negative test
|
BC > AC (Conduction HL)
|
|
What is a false negative Rinne test?
|
Total deafness
Pt. will hear fork on mastoid of deaf ear b/c it transmits vibrations across the skull to the healthy ear |
|
How would a perforation look with an otoscopic exam?
|
Perforations may be central or marginal. Present as a hole and name described where the perforation is. A central does not involve the margin of the tympanic membrane.
Marginal is more severe. |
|
Nasal conditions usually occur ______?
|
Middle meatus
|
|
Nasal:
Thin watery discharge |
Viral or Allergic rxn
|
|
Nasal:
Thick purulent |
Bacterial infection
|
|
Nasal:
Bloody |
Neoplasm, trauma, fungal infxn
|
|
Nasal:
Foul Smelling |
Foreign object, chronic sinusitis, malignant ds
|
|
Nasal:
Clear watery discharge increases w/ coughing or bending head forward |
CSF
|
|
What is the difference between the Nasal and Sinus Exam?
|
Nasal:
Inspection, Palpation, Olfactory, Internal Exam Sinus: Inspection, Palpation, Percussion, Transillumination |
|
How are turbinates clinically different from a polyp?
|
Polyp:
-Most common cause of anosmia -Pale, Translucent, and moveable -Round, Darker pink, Smooth, and on the Medial Meatus Turbinate: -Round, light pink, and ridged |
|
Difference between acute rhinitis and allergic rhinitis
|
Acute Rhinitis is non-seasonal and due to stress, nasal spray abuse, prego, hypothyroidism
Allergic Rhinitis is seasonal and non-seasonal congestion due to allergens Seasonal: Spring = weeds, pollen, trees Fall = weeds and pollen Summer = grass Non-seasonal: -Animal dander -Dust -Mold |
