What is the tongue splitting process?
if your considering getting it done know this
the tounge has a high chance of re-attactching itself and growing back together within the first year
so it might not be as a big of a split as you want it,
it might not look like how you wanted it too,
and it might completely grow back together leaving a very noticable scar
would it still grow back if you put the zipper on it???
