Q: How does the ARTAS robot control the depth of the incision in Robotic FUE? — B.V., Old Greenwich, CT

A: The ARTAS robotic system is equipped with advanced sensors that determine the precise depth of the sharp and blunt needles used both in the graft harvesting step and for recipient site creation. The robot automatically adjusts to the precise depth needed for the non-traumatic extraction of the grafts. The tip of the punching mechanism contains depth markings so that the physician can visually override the punch when he wants to fine-tune its action. While monitoring the procedure in real time, if it is observed that the punches are too superficial or too deep, punch depth can be modified using the robot’s computer system.

The physician can also use the ARTAS system to precisely control the depth of recipient sites. As with harvesting, the robot automatically adjusts the depth based on parameters set by the physician and the doctor can then make further adjustments, in real-time, during the procedure.

Q: How far into the scalp are the grafts placed and is the follicle far enough into the scalp that it will not be damaged? I have heard that the critical time to not touch your scalp is the first 2-3 weeks after the procedure. — M.G., Hillsborough, C.A.

A: The growth part of the follicle is 3-4mm into the scalp. Grafts can be dislodged the first 10 days, so you need to be careful not to scrub your scalp during this period. After that, the grafts are permanent. At 2-3 weeks they can’t be dislodged, even by vigorous scrubbing.

Q: After the day of the procedure, I could see what appeared as white specks on top of my scalp. Some are sticking out above the scalp more than others. I was wondering if the entire follicular unit should be at the level of the scalp. Is it normal for some part of it to be above the scalp? (I did not receive the procedure from you.) — T.C., London, U.K.

A: It is normal for the grafts to be a little elevated and you should expect them to flatten as they heal.

The effect may be exaggerated in the shower as the grafts become hydrated, but they should settle down soon after you dry off.

As long as the grafts were no larger than follicular units and the graft sites no larger than the size of a 19g needle, there should be no permanent marks.
