Question

Otitis media and sinusitis are usually preceded by a(n)
A)middle ear infection.
B)pseudomonal infection.
C)oropharyngeal infection.
D)nasopharyngeal infection.

Accepted Answer

Otitis media and sinusitis are infections that occur in the middle ear and sinuses respectively. These structures are connected to the upper respiratory tract via the nasopharynx. Therefore, infections that originate in the nasopharynx (e.g. viral or bacterial infections), can spread to the middle ear and sinuses, causing otitis media and sinusitis.
