The MEEK micrografting devices are made to easily apply the MEEK technique. The MEEK machine allows the user to easily and controllably cut skin grafts of 42 mm × 42 mm (1.65” × 1.65”) into smaller pieces of skin of 3 mm × 3 mm in size. These skin islands are then transferred to specially folded gauzes. Upon expansion of the gauzes, the distance between the individual islands is increased. The way the gauzes have been folded determines the expansion ratio.
Originally postulated to treat burns by dr. Meek in 1958, the then called MEEK-Wall technique required tremendous skill for it to be applied successfully. Despite positive results, the technique was shelved when mesh grafting was introduced in 1964. Decades later new technology bred new possibilities and the MEEK-Wall technique was modified by Humeca in cooperation with surgeons of the burn center of the Red Cross Hospital at Beverwijk, The Netherlands.
After years of research and development, a newly designed machine was introduced onto the market in 1993. The MEEK machine and prefolded gauzes ironed out many steps of the original procedure. Since its release, the modified MEEK technique has been sold to burn centers worldwide and is used every day.
Most techniques are limited in the size of burn wounds they can treat. However, the MEEK technique is suitable for small and large TBSA burns. Gauzes with expansion ratios of 1:2, 1:3, 1:4, 1:6 and 1:9 are available. The expansion ratio of the gauzes is mathematically supported, which makes the need for donor site availability smaller when compared to the donor site needed for other skin grafting techniques.
Additionally, clinical outcome and success rate of MEEK micrografting have shown to be increased when compared to other skin grafting methods. This is partly related to faster epithelialization and wound closure.
•Superior results compared to mesh grafting.1,2,3,4
•Suitable for complex cases with unfavorablewound conditions.5
•Uniform epithelization due to homogenous distribution of skin islands, of which the dermal sides arein full contact with the wound bed.6,7,8,9
•Faster full epithelialization compared to meshgrafting, which is caused by a larger total marginand a shorter distance between skin margins.6,7,8,9
•The epithelization time for a 1:6 expansion usingMEEK is 3 – 4 weeks.6,7,8,9
•The risk of infection is lower compared to meshgrafting due to, among others faster epithelialization.1,10
•Suitable for small and large percentages TBSA.1,6,7,8,10,11,12,13,14,15,16,17,18
•True expansion ratio resulting in a required smallerdonor site size or the ability to treat a larger percentage TBSA using the same donor site size compared to mesh grafting. 1,6,7,8,10,11,12,13,14,15,16,17,18
•Suitable for a combined treatment with primary orcultured skin cell therapies.19
