to avoid extensive facial reconstruction surgery,

get a Nitto Technomic or Perioscopa stem, they are made with a much longer quill .
or get a TUBE TYPE STEM RAISER It is reduced in diameter to go inside your fork , 22.2/7/8"

then the upper portion has the same Inside diameter to insert your stem into..

the ID on the top is the OD on the bottom..

the tube stem raisers on the bottom.
