Actor Mark Ruffalo, 46, was diagnosed with an acoustic neuroma in 2001, which left him partly facially paralyzed for 10 months. He recovered, but lost all of his hearing in his left ear. Here Mark shares his experiences with the tumour diagnosis and treatment.

The actor has learned to cope with his single-sided deafness, but for those who don’t want to, there is help available.

The Baha system can help restore the hearing by sending sound through the bone directly to the functioning inner ear on the other side.
