An video of a tongue getting cut. Dose someone know what I am talking about?

I saw a video around 5-6 years ago that still haunts me. It was of a woman, possibly a doctor, cutting a man's tongue in a hospital setting. None of it was blurred, and blood was spilling everywhere, making the scene shockingly graphic. I have no idea if it was real or staged, but the imagery stuck with me ever since. I've searched online, but I can't find anything similar or any explanation. Does anyone know what I’m talking about? It feels like a strange nightmare I can’t shake off, and I wonder if anyone else has seen it.
