Ear pressure sensation after resection of meningoma. Anyone else?

7 months ago I had a resection of a sizeable convex meningioma in the right upper frontal hemisphere. Since about a month I am experiencing a pressure sensation in both of my ears. It is the same sensation you get during the airplane take off. My half year MRI didn't show any change, I have no other symptomes and otherwise feel just fine. I was curious if any of you had a similar experience.
