There is a major difference between mini / micro grafting and follicular unit transplantation ( FUT ). In mini / micro grafting small grafts are cut to size without respect for the integrity of follicular unit. Follicular unit transplanting consists of using stereomicroscopes to carefully remove these units infact from the skin to transplant to the balding areas. The hairless skin between the follicles is removed so that you get a genuine “hair” transplant. It’s important to do this because the last thing a patiesnt with bald skin needs is to have more bald skin transplanted alone with the hair.
A micro – graft is a graft containing 1 to 2 hairs and a mini – graft is a graft containing 3 to 6 the follicular units. They are prepared by removing the donor strip with a multi-bladed knife, which results in more hair transaction ( cutting ) than with a single – bladed knife. After the strip removal the grafts are prepared and cut to size using little or no magnification and with little respect for the natural follicular units. This causes there problems :
- More transaction
- Transplanting the hairless skin
- Less density in the recipient area due to the hairless skin being transplanted and the larger size of the grafts.
The main advantage of mini / micro grafting are that it is faster for the surgeon and requires less skill and manpower for the assistants and is, therefore cheaper.
