Summary

In suction-assisted excision (S.A.E.), the use of negative pressure can eliminate the step of pulling the grafts with forceps as they are carried to a collection canister as soon as they are punched. The most important proposed advantages are that it can speed the procedure, reduce the physical trauma to the grafts, and reduce the number of assistants. The risk of drying and desiccation due to vacuum-produced air flowing over grafts was an initial concern with these systems; however, this has diminished with the development of devices that have improved fluid-filled collection canisters and hydrating systems. Concerns over punch size and depth as well as trauma from “drag-and-drop” technique have been voiced, but these have also been addressed over the years. Improvements some device makers have added to their machines include the following: a better interface with touch screen control, ability to count grafts and record patient and procedure data, graft counter, better control of suction, depth control, wireless foot pedals, dual and/or illuminated handpieces, and better collection canisters to limit dehydration. The four S.A.E. device makers referred to in this chapter are NeoGraft, SmartGraft, Fuetor, and Atera. A few of the S.A.E devices have the ability to implant grafts, but in reality, this function is not often used.
