Available techniques and their uses
Technique of tissue gain with the « Frechet Extender » or scalp extension.
This technique allows to increase the surface of the skin, doubling the surface of the hair bearing scalp and thus eliminates the bald area.
A sheet of bioelastic silicon is introduced under the skin, stretched and affixed temporarily. By exerting a permanent linear traction it stimulates the production of collagen and elastic fibres. As a result after 2 to 3 months, the hair bearing scalp gradually extends and progressively replaces the bald area of the top (vertex) and the back of the head which can then be removed at the same time as the extender. This bioelastic is called the «Frechet extender» and is patented worldwide.
The procedure is performed under local anaesthesia on an outpatient basis. The patient can resume his normal activities usually after 3 days.
In most instances the surgery is carried out with little discomfort to the patient and the extender is not apparent to the casual eye.
This is the only technique which treats effectively and totally the top and back of the scalp.
It should be noted that grafts (transplants) can only treat smaller areas of baldness such as frontal or temporal areas, as there is not a sufficient quantity of hair in the “donor zone”. (The donor zone, typically at the back of the head, contains hairs which are genetically programmed to grow all life long).
In the case of a patient with baldness of the crown, the scalp extension procedure will redistribute 15000 hairs uniformly over the area with a totally natural appearance
When the extender is being removed, another technique which he has invented the triple transposition flap also called the «Frechet Flap» will be performed to produce an attractive rounded shape on the top of the head and allow the hair to grow naturally towards the nape of the neck.
The treatment is then completed with grafts filling in the frontal bald area.
Other uses of the Frechet extender:
The Frechet extender is also used for the treatment of burns, scalp tumours, pseudo-pelade, scarring alopecia, giant naevi, etc...
