I find it interesting how many physicians and others who have never seen or used a device suddenly become experts in its pros and cons. This is not a personal attack on any one physician or group, and we probably have all (myself included) jumped to hasty inacurate conclusions about some treatment or another when it was first presented to us.
Those physicians who attended my FUE video-presentation ("Follicular Unit Extraction Using a Self-Rotating Device") at the ISHRS in Amsterdam in 2009 will likely already be aware of the "reality" vs. the "myth" when it comes to NeoGraft. Additional research is currently being completed on NeoGraft FUE which will be presented and published at upcoming medical conferences.
MYTH: "The NeoGraft's fast mechanical rotation twists the follicles/grafts which is in some way harmful."
Reality: While the NeoGraft's handpiece can be set at high-speed rotation, in our office these settings are simply not used. In fact, the rotation of the depth-limited handpiece during the initial scoring of the skin prior to extraction of the follicular unit is roughly the same as if you performed the extraction manually. It is important to understand that the rotation is activated by a foot-pedal switch. Once the tip of the instrument is aligned over the follicular unit, the rotation is then activated and gentle, steady pressure is applied as the device is guided carefully into the skin. The tip of the device rotates only rotates maybe once or twice as it enters the skin to a depth of 2-3mm. Then, after a certain number of these incisions are made, these grafts are extracted gently with forceps. In our experience, the use of tumescent fluid in the upper dermis stabilizes the tissue further and assists greatly with accuracy and speed.
In our hands, the benefit of the NeoGraft device is the ergonomics involved with the handpiece which allows a repetitive motion to occur with excellent visualization of the angle of exit of the hairs. This produces excellent quality grafts (very little transection occurs) at a significantly higher rate of speed compared to manual FUE.
Note: A tool is only as good as the person who yields it.
