Magnification Dissection
How are the follicular unit grafts dissected? Dr.
Keene introduced a new form of magnification for graft dissection. She first
announced it at the International Society of Hair Restoration Surgery Florida
conference in 2002, and then presented it in Rome in 2003. State of the art
clinics are now adapting this improved form of dissection over the microscope. Research has shown that graft dissection using
microscopic magnification reduces the incidence of transection, increasing
graft yield during graft dissection. Table top microscopes have limited
working distance and visual field, with limited range of motion for the users
head and neck. Dr. Keene
sought a way to improve ergonomics and magnification over the commonly used
microscopes used by hair transplant clinics. While seeking an
ergonomically improved method of graft magnification, Dr. Keene worked with an
engineer to co-develop the video magnification system, which not only offers
ergonomic advantages, but also allows the doctor the opportunity to see every
graft as it is being dissected. This also provides her the opportunity for
maximum oversight and quality assurance before the grafts are placed!
Dissection Kit
for Optimal Graft Handling As
they are dissected, the grafts are stored in chilled saline in a dissection kit
that Dr. Keene designed to maintain optimal graft hydration throughout the
surgery. The graft receptacles can be transferred directly to the doctor’s or
assistant’s finger for placing, without additional graft handling. Graft
drying is known to be one of the most detrimental factors influencing graft
survival, and this system helps reduce the risk of graft drying by maintaining
hydration during both the dissection and placing phases of surgery. Many
clinics dissect grafts on a dry surface, place them in Petrie dishes, and then
transfer grafts to a gloved hand—subjecting them to unnecessary handling and
the risk of drying. The use of the dissection kit decreases graft handling, and
decreases the risk of graft dehydration. | Home | Surgical
