Mini-micrografting is similar to follicular unit extraction, yet not as advanced.
The mini-micrografting procedure involves removing donor tissue with a multi-bladed knife. The tissue is then cut into smaller pieces using direct visualization; therefore, instead of using a microscope to cut the tissue, a surgeon might use the help of a regular ruler.
The size of the grafts is dependent upon the decision of the surgeon and patient who can choose to cut micrografts (1-2 hairs) or minigrafts (3-6 hairs). When cutting the grafts, the excess skin is not trimmed thereby making the wounds larger than necessary upon implantation.
One benefit of mini-micrografting is that it is time and cost efficient. Most likely, that is the main reason why it is such a popular surgical choice.
Below is an overview of the problems associated with mini-micrografting (in comparison to follicular unit extraction):
-
- Grafts are cut in such a way that individual follicular units may be split up or damaged
-
- Harvesting technique does not ensure that each follicle will be kept intact
-
- Grafts are larger because excess tissue is not trimmed
-
- Healing time is very slow
Follicular Unit Extraction vs. Mini-Micrografting
Most up-to-date hair restoration surgeons recommend that patients choose follicular unit extraction over mini-micrografting because it produces a more natural result, has a faster healing time, and is more efficient in preserving donor hair.
