Answer:
Otitis media is generally caused by dysfunction of the Eustachian tube, which can be due to Pharyngitis.
Step-by-step explanation:
The otitis media is an infection or inflammation of the middle ear and is mostly caused by the inflammation of the mucous membranes in the nasopharynx leading to dysfunction of the Eustachian tube. This can be caused due to a upper respiratory tract viral infection or streptococcal pharyngitis (strep throat) or due to some allergy.
Pharyngitis or sore throat is a type of inflammation caused by upper respiratory tract viral infection.
Therefore, Otitis media can be caused by Pharyngitis and thus it is associated with it.
