Hallo

Is it possible that air concentrates in the sphenoid sinus, due to swelling
of the sphenoethmoidal recess.
Is it also possible that air concentrates in the middle ear due to dysfunction of the tuba eustachi.
I have Pressure in the Backhead since December. At one Occasion the pressure was rising intensly and
lowered down when suddenly air streamed out of a channel on the nose.
But i dont know if the air either streamed out of the sphenoid sinus or elsewhere.
The Doctors I have asked do not have an answer to my symptoms.

Greetings from Austria
