Not all clinics are using single blade scalpels.
The #1 advantage to a single blade scalpel is less graft "transection" (Cutting and ruining grafts). Obviously, this allows the hair transplant surgeon to get the maximum amount of donor grafts.
The disadvantage is it takes more time and a hair transplant surgeon needs to be highly skilled. Dr Wong will actually adjust the size of the donor strip according to the laxity in different areas of the strip. You can't do this with a multi-blade scalpel.
The benefits of a multi-blade scalpel is it's faster and easier fo the surgeon to close the donor incision.
The negative of a multi-blade is more transection of grafts occurs, which lowers your graft yield.
I remember reading that it is estimated that transection rates of 30% occur with mutli-blade scalpels. So for every 1000 grafts 300 of those are lost to transection.
So if a donor has a potential amount of 3900 grafts you would lose 900 grafts due to transection by a multi-blade scalpel. 900 grafts are alot of grafts to lose!
For a person, like myself, who needs every dang graft that is a devastating amount of grafts to lose.
I will do a search for the article, I read this on, and post it for you to read.
