Are these 4000 and 5000 graft sessions being done on men that are higher on the norwood scale, say 6 or 7, because these doctors are willing to spend more time and resources? Or are we now going to see these large sessions done on men who are lower on the scale because these doctors can now pack more in closer together? Are we headed towards one session and done? With the recovery time and waiting with these procedures that would be a major advancement in ht's in more ways than one.
