- A.
Chronic
- B.
Mild
- C.
High
- D.

Cholesteatoma, eustachian tube dysfunction, neoplasm, or congenital malformation of the middle ear may block airflow to the mastoid and cause chronic _____
- A.
Mastoiditis
- B.
Otitis media
- C.
Labyrinthitis
- D.
Senioritis
Correct Answer
A. MastoiditisExplanation
Cholesteatoma, eustachian tube dysfunction, neoplasm, or congenital malformation of the middle ear can all obstruct the airflow to the mastoid, leading to a chronic condition known as mastoiditis. This inflammation of the mastoid bone can cause symptoms such as pain, swelling, and discharge from the ear. It is typically associated with a previous or ongoing infection of the middle ear, known as otitis media. Labyrinthitis refers to inflammation of the inner ear, which is a separate condition. Senioritis is not a medical term and is unrelated to the given context.Rate this question:

The middle ear extends from the TM to the medial wall of the middle ear cleft. It includes the TM _____, ______, ______.
- A.
Malleus, cochlea, stapes
- B.
Malleus, stapes, incus
- C.
Malleus, saccule, incus
- D.
Malleus, semicircular canals, incus
Correct Answer
B. Malleus, stapes, incusExplanation
The middle ear extends from the TM (tympanic membrane) to the medial wall of the middle ear cleft. It includes the malleus, stapes, and incus. These are the three small bones in the middle ear known as the ossicles. The malleus is attached to the TM and transmits sound vibrations to the incus. The incus then passes the vibrations to the stapes, which in turn sends them to the inner ear. These three bones work together to amplify and transmit sound from the outer ear to the inner ear.Rate this question:
