,Question 10: Sensorineural Hearing Loss
Answer: Caused by a lesion in the organ of corti or the central neural pathways of the ear, including CN
VIII and auditory cortex
Question 11: Conductive Hearing Loss
Answer: Hearing loss or impairment resulting from interference with the transmission of sound waves to
the cochlea
Question 12: Presbycusis
Answer: * Age related hearing loss * Usually after age 50 when otic hair cells degenerate * High
frequency hearing loss that is equal bilateral
Question 13: Differential Dx Sensorineural Hearing Loss
Answer: * Presbycusis * Meniere's Disease * Tumors (Acoustic Neuroma) * Medications
(Aminoglycocides, aspirin, Quinine) * Disease (Syphilis, viral infections such as mumps, or bacterial
infection)
Question 14: Differential Dx Conductive Hearing Loss
Answer: * Cerumen impaction * Perforated Tympanic Membrane * Chronic Infections * Congenital
Abnormalities
Question 15: * Otosclerosis or tympanosclerosis
Answer: * Temporal bone fractures
Question 16: Meniere's disease
Answer: Abnormal condition within the labyrinth of the inner ear that can cause fluctuating loss of
hearing. The symptoms are dizziness or vertigo, hearing loss, and tinnitus (ringing in the ears).
Question 17: Acoustic Neuroma
Answer: Rare tumor on the auditory nerve (8th cranial nerve) that causes unilateral vertigo, tinnitus, and
hearing loss. Sometimes associated with a headache. May also have neurologic changes such as facial
weakness, tingling, loss of taste and dysphagia.
Question 18: Dysphagia
Answer: difficulty swallowing
Question 19: aphasia
Answer: difficulty speaking

, Question 20: Subjective findings for hearing loss
Answer: * Difficulty hearing * Tinnitus * Dizziness * Vertigo * Pain, Pressure, Popping in ears
Question 21: Cholesteotoma
Answer: a type of tumor that can occur in the middle ear and cause a conductive hearing loss
(keratonizing Squamous Epithelium)
Question 22: Diagnostic tests for Hearing loss
Answer: * CT or MRI - Identify acoustic Neuromas or Tympanic Paragangliomas * Audiometry speech
testing, and middle ear pressure * MRI may detect cholesteotoma
Question 23: Differential Diagnosis Hearing Loss
Answer: Determine if its sensorineural or conductive
Question 24: Cerumen Impaction Management
Answer: * Place 1:1 mixture of warm hydrogen pyroxide and mineral oil in external ear canal for 1 hour.
Then lavage with warm saline. * or us Debrox (6.5% carbamide peroxide * or use docusate sodium
liquid ** press post and pre auricle then up and down to work the wax out, dry with warm hair dryer.
*** Use for 1 week before returning for ear canal disimpaction **** Do not disimpact if tympanic
membrane is perforated
Question 25: Cerumen impaction complication
Answer: If trauma to canal during disimpaction: Treat with cortisporin otic, 4 drops 3 to 4 times daily
for 5 to 7 days)
Question 26: Referal for sensorineural hearing loss
Answer: * ENT -> perforation of TM, damage to Oscicles, tympanosclerosis, otosclerosis, tumor,
temporal bone injury, Menier's disease, acoustic neuromas * Audiology -> hearing loss
Question 27: Education to prevent hearing loss
Answer: * Avoid loud noises * Protect ears in noisy environments * Treat underlying causes (otitis
media, cholesteotoam, acoustic neruoma, etc)
Question 28: Risk factors for Tinnitus
Answer: * hearing loss and chronic exposure to loud noise * Labyrinthitis * Meniere's disease * Otitis
Media * Otitis Externa * Otosclerosis * Earcanal blockage * high or low BP * Head trauma * Anemia *
thyroid disease * Allergies
