What is the name of the sinus behind your ear?

Question

I'm having pain behind my right ear and my M.D. said it was a sinus problem. I can't find the name of this sinus anywhere.

Answer 1

The term "sinuses" usually refer to the paranasal sinuses. There are many other sinuses not only in the skull but throughout the human body. The term sinus is Latin for "bay", "pocket", "curve" or "bosom."

The paranasal sinuses are not the only sinuses within the skull; the mastoid cells in the mastoid bone around the middle ear are also a type of sinus.

Paranasal sinuses are air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face. Humans possess a number of paranasal sinuses, divided into subgroups that are named according to the bones within which the sinuses lie:

The maxillary sinuses, also called the maxillary antra and the largest of the paranasal sinuses, are under the eyes, in the maxillary bones (cheek bones).

The frontal sinuses, over the eyes, in the frontal bone, which forms the hard part of the forehead.

The ethmoid sinuses, which are formed from several discrete air cells within the ethmoid bone between the nose and the eyes.

The sphenoid sinuses, in the sphenoid bone at the center of the skull base under the pituitary gland.

Answer 2

Is mastoid considered a sinus? There are mastoid air cells. Our sinuses are frontal, ethmoid, maxillary, and sphenoid.
