Yes we do know for sure that his isnt missing his nose. That is completely false because Klein is not a plastic surgeon. He is a dermatologist he doesn't do surgeries. He was plumping up MJs nose with injections. MJ's nose was in tack. Dr Klein said the bridge of his nose was weak and to thin. He may have had procedures to rebuild or replace the cartlege at one time or another. What you saw was most likely tape on the bridge, placed there to help protect and shape it after (procedures) either surgery or injections. Much Like the picture below .. He appeared in court the next day without the tape and his nose looked fine.
The autopsy mentions details of tattoo's on his eyebrows lip line and hairline. They wouldn't miss the detail of missing part of his nose. They would legally have to put that in the autopsy record if it was so. But even If I knew for fact it was true. I wouldn't publically speak of it for his sake. He is mocked and trampled on enough on the outside. It must have been terrible for him to see or read those stories always mocking him over his nose. No wonder he hid behind a mask.
