Preparation of recipient-incisions

Preparation of the recipient-incisions during the process of hair restoration

There are various methods to create incisions on the recipient site in order to relocate extracted grafts:

- Drill

- Laser

- Needles

- Lateral Slits using scalpels or special blades

The use of a laser or a drill to create an incision on the recipient site of the scalp has decreased and can now be seen rarely. As the skin was often damaged too heavily by the use of a laser the grafts being inserted had only little chance to survive. The growing yield appeared to be very low and transplanted hairs could not grow properly.

In the recent years the two most common devices to be used during the process of hair restoration had turned out to be needles and small scalpels, resp. specially manufactured blades. Scalpels and blades are commonly used to create either vertical or lateral slits. Both ways have been approved to achieve excellent results.

It is due to the personal preference of a surgeon that either a needle or the lateral-slit-method is used during the procedure to create incisions on the recipient area.

However, there are substantial differences between the size of the instrument to be used as well as there are large differences about the amount of grafts being placed into an area measured per square centimeter. The smaller and more precisely the instruments the more grafts / FU's per square centimeter can be placed.

Incisions by needle:

Famous and leading hair transplant surgeons are using a range of needles varying from 25 gauge (0.5 mm) to 20 gauge (0.9 mm).

See the different size of the needles on the picture below!

The different size of needles can be measured very accurately by special devices:

The size of the needle describes the inner diameter. A needle of 25 gauge corresponds to an inner diameter of 0.5 mm and an outer diameter of 0.518 mm.

Lateral/vertical Slits:

In order to achieve high densities for the final outcome many leading surgeons using the lateral/vertical-slit-method need a special manufactured cutting-device, called the "Cutting Edge", which is able to minimize the blades´ size in order to create precise and delicate incisions around the recipient zone.

The device even allows to create blades of 0.7 mm size.

After controlling the size of the blade the accurate effects of the "cutting edge" will be apparent.
