The 88-year-old actress – who plays Dot Branning in the BBC One soap – told The Sun that she's been struggling with her hearing ever since recently taking a flight to Scotland.
She explained: "Unfortunately it happened when I was going up to Glasgow for a charity. My ears impacted and they haven't come back since. I hope that they might do at some moment. I thought it was a bit unkind given I was flying up for charity!"
The newspaper says June initially revealed her hearing problems during a Q&A at London's BFI with former co-star Barbara Windsor.
June was seated in the front row but struggled to hear what Barbara was saying on stage, so her co-star brought her up on stage alongside her.
Reports claim June then said: Are you talking to me Babs? Tell me, because I am deaf you see and it is very hard for me to hear so I don't know what you are talking about. What did you say to me? Sorry, I would like you all to shout because I can't hear, you see. I am ever so sorry. I am straining here..."
The star has also had problems with her vision in recent times, saying earlier this year her sight is not always good but giving up her EastEnders job is not an option because of financial concerns.
"I see things in my eyes now. My eyes are not very good. In the left occasionally I do get this small circle with what looks like cross-wires. I do pray about my sight – maybe it will return," she told BBC's Radio 4.
June joined EastEnders in 1985 and has played the character of Dot Branning – formerly Cotton – ever since, barring a four-year break in the 1990s.
