Sudden deafness in an ear and type 2 diabetes

Hello everyone:
For about 5 years I have serious hearing problems in the left ear.Ours, cranial resonance to rule out a possible tumor in the auditory nerve and so
I was detected by type 2 diabetes about 8 years ago, and the funny thing is that my mother, who also had type 2 diabetes suffered the same auditory problem, she was told that she had had a microembolism in one of the small blood vessels of the ear.
But I do not stop looking for information on the Internet to try to clarify my problems, and I have seen various articles relating this deafness to diabetes
Any of you have information on this topic?
Thank you so much

@fosphorero, auditory problems have many people who are not diabetic, but who occur in close relatives.Maybe it's not for diabetes ..

My grandmother had and my father has wear of the auditory nerve.They are not diabetic.
I am diabetic and I hear great
