Consider a disease whereby cilia within the epithelial lining of the paranasal sinuses are destroyed. What would be some of the consequences?

Question 2

Caroline goes to the doctor complaining of ear pain and fever. The doctor notices that the ear infection is not limited to the middle and inner ear but has traveled posteriorly. Explain where the infection has likely traveled, how it was able to move beyond the inner ear, and what additional symptoms she may exhibit with the infection.

Answer to Question 1

The ciliated epithelium moves mucus back toward the throat, where it is eventually swallowed or expelled coughing. Mucus traps foreign particulates, such as dust or microorganisms, which in the absence of cilia would build up within the paranasal sinuses. Possible consequences may include congestion, pain, sinusitis, and spread of infections into the respiratory tract.

Answer to Question 2

Caroline's inner ear infection has likely spread to the mastoid process causing mastoiditis. The infection traveled through the mastoid air cells which are connected to the middle ear cavity. She may also experience swelling and redness behind the ear at the mastoid process.
