Hearing Loss Cochlear Implants and Surgical Treatments Test 2

Question 1

Which surgical procedure is used to treat otosclerosis that has fixed the stapes bone?

Accepted Answer

Stapedectomy or stapedotomy

Answer

Stapedectomy (removing the stapes) or stapedotomy (creating a small hole in the stapes footplate) replaces the fixed stapes with a prosthesis, restoring sound conduction and improving conductive hearing loss.

Question 2

Tympanoplasty is a surgical procedure that repairs which structure?

Accepted Answer

The eardrum (tympanic membrane) and/or ossicular chain

Answer

Tympanoplasty repairs perforations in the tympanic membrane and may also include reconstruction of the ossicular chain (ossiculoplasty) to restore hearing.

Question 3

Myringotomy with tympanostomy tube placement is a common surgical treatment for:

Accepted Answer

Recurrent or chronic otitis media with effusion (glue ear)

Answer

Pressure equalization (PE) tubes are surgically inserted through a small myringotomy incision to ventilate the middle ear and drain fluid in children with recurrent or persistent otitis media with effusion.

Question 4

Acoustic neuroma (vestibular schwannoma) is a benign tumor that grows on which nerve?

Accepted Answer

The vestibulocochlear nerve (cranial nerve VIII)

Answer

Acoustic neuromas (vestibular schwannomas) grow on the vestibulocochlear nerve (CN VIII), typically on the vestibular branch, causing progressive unilateral sensorineural hearing loss, tinnitus, and balance problems.

Question 5

Cochlear ossification following bacterial meningitis creates a surgical urgency for cochlear implantation because:

Accepted Answer

New bone formation in the cochlea can block the electrode array from being inserted

Answer

Following meningitis, labyrinthitis ossificans (cochlear ossification) can cause new bone to fill the cochlea, potentially blocking full electrode insertion and compromising cochlear implant outcomes.
