Once scar tissue forms around the shrapnel, it may be easier to remove with surgery.
Rebagliati said the piece of shrapnel that came out of Mann's mouth may have been embedded in the soft tissue around his jaw, close enough to either the nerves or muscles involved in mouth movements, which may have been the source of his problems eating and speaking.
"It was probably all mechanical," Rebagliati said. "Like having a ball bearing stuck in a doorway."
Mann still has several bits of shrapnel left in his hands that have never come out or been removed. But now that the shrapnel from his jaw is gone, Mann is better able to speak and eat and his jaw pain is gone.
"I've got no pain at all," Mann said. "[My wife] is quite pleased with it."
"It was a shock, yes," said Mann's wife, Constance. "But he just had this stuff come away from him and he's alright now."
