Hair Lateral Slit Technique

Lateral Slit Technique

This is a technique used during a hair transplant in which hair grafts are inserted into a designated area of the scalp via a series of incisions. There are several techniques designed for this purpose but the lateral slit technique is often used by surgeons who prefer a high level of control over the direction which the newly grown hairs will take.

This technique is used during Follicular Unit Transplantation (FUT) surgery. It has also been used to great extent in other types of hair transplant surgery but has gained popularity as an exact and systemised approach for FUT procedures.

Why is the lateral slit technique preferred during follicular unit transplantation?

The FUT procedure requires a high degree of skill and preciseness in order to insert the hair grafts at an acute angle on the scalp. The lateral slit technique is a type of incision, made at an angle and in a particular direction on the top of the scalp.

These incisions are made at a 45 to 90 degree angle which will result in newly grown hair that lies flat against the scalp. This is particularly useful in areas of the scalp such as the temples where natural hair grows flat against the scalp.

Basically, the type of incision determines the direction of the new hair growth. The aim is to replicate the different ways your hair grows so that it looks natural.

The surgeon will closely examine the structure and direction of your natural hair so that he/she is able to mimic this with the hair grafts.

The difference between the lateral slit technique and other hair transplant incisions

The difference is the angle at which the lateral slit incisions are made. As the name says, they are made at a perpendicular angle (right angle) along the scalp which is less likely to affect the underlying structure of the scalp.

This type of incision is less invasive as well. Plus it enables the surgeon to pack more grafts together within a small area of the scalp without them pushing each other out of place. This means a higher density of grafts which results in an increased volume of hair.

Another factor is the depth of the incision and the effect this has on recovery time. A deep incision causes trauma to the scalp in the form of swelling and scarring which take longer to heal. This is often the case if sharp pointed blades are used as these dig deep into the surface of the scalp.

However, the lateral slit technique uses blades which are custom designed to mimic the shape of a hair follicle. This means a minimally invasive incision, leading to a reduced risk of inflammation, scarring and pitting of the scalp.

The aim is full scalp coverage and an aesthetic appearance.
