Eight facts about Mark Ruffalo at a glance, tracking the details that anchor his public story.

What Was Mark Ruffalo Diagnosed With?

In 2001, shortly after finishing work on the film The Last Castle, Ruffalo learned he had a vestibular schwannoma—commonly called an acoustic neuroma. According to Wikipedia (user‑edited encyclopedia), the tumor was benign but required immediate surgery. Doctors warned him before the operation that there was a 20% risk of facial nerve injury and a 70% risk of hearing loss, as reported by Global News (Canadian news outlet).

Is Mark Ruffalo deaf?

• He is not completely deaf; he lost hearing in his left ear only. Wikipedia states he remains deaf in that ear.
• A 2017 interview clip, available on YouTube (video platform), shows Ruffalo confirming he had no hearing on his left side at that time.

How did Mark Ruffalo lose hearing in one ear?

• The surgery to remove the acoustic neuroma severed the auditory nerve on his left side. Encyclopaedia Britannica notes that the procedure also caused temporary partial facial paralysis.
• Ruffalo described the experience in a 2013 interview posted on YouTube (video platform), saying he was partially facially paralyzed for about 10 months.

The implication: Ruffalo’s willingness to speak openly about the tumor turned a private medical scare into a public lesson about vulnerability and resilience.
