They are all connected. The nasopharynx is connected posterior and inferiorly to the paranasal sinuses and is connected to the middle ear by the auditory (Eustachian) tubes. The mucous membranes of the nose, paranasal sinuses, pharynx, and middle ear are all connected by ducts. Infections can spread through all those areas.
mastoid sinuses
Eustachian tube
The temporal bone contains the middle ear cavity, which is not a paranasal sinus.
opening of the pharyngotympanic tube
the auditory (pharyngotympanic) tube
Yes, the auditory tube connects the middle ear to the nasopharynx, allowing for equalization of pressure between the middle ear space and the atmosphere.
eustachian tube
The maxillary sinuses drain into the middle meatus of the nasal cavity through the semilunar hiatus.
The eustachian tube connects the middle ear to the nasopharynx, allowing equalization of pressure between the two regions. This helps to regulate air pressure in the middle ear and allows for proper hearing and balance.
The Eustachian tube connects the middle ear cavity to the nasopharynx. It aerates the middle ear system into the nasopharynx. Normal opening of the Eustachian tube equalizes atmospheric pressure in the middle ear, closing of the tube protects the middle ear from unwanted pressure fluctuations and loud sounds
The auditory tube, also known as the Eustachian tube, connects the middle ear to the nasopharynx. This connection helps to equalize pressure between the middle ear and the environment, allowing for proper hearing function and ventilation of the middle ear.
The middle ear is connected to the nasopharynx by the auditory (eustachian) tube. This tube helps equalize pressure between the middle ear and the atmosphere and allows for drainage of fluids from the middle ear to the back of the throat.
