The Mercedes incision in hair restoration

Area of Science:

• Surgical Techniques
• Dermatology
• Hair Restoration

Background:

• Standard hair transplantation uses circular or slit grafts, leading to row cropping and graft compression.
• Scar contracture can cause graft compression, resulting in undesirable cosmetic outcomes like tufting.
• Existing methods often produce unnatural results due to graft placement limitations.

Purpose of the Study:

• To introduce and evaluate the efficacy of the expansile Mercedes incision technique in hair transplantation.
• To address and overcome the aesthetic drawbacks associated with traditional hair graft placement methods.
• To offer a quicker and more aesthetically pleasing hair restoration solution.

Main Methods:

• Donor minigrafts were harvested using standard biopsy punch or strip methods.
• A three-armed stellate (Mercedes logo-shaped) incision was created at the recipient site using a scalpel.
• Grafts were inserted into the stellate incisions, oriented parallel to native hair shafts, with triangulation preventing compression.

Main Results:

• The Mercedes incision technique effectively eliminates graft compression by spreading grafts in three directions.
• Randomized orientation of the stellate incisions prevents the appearance of row cropping.
• The technique allows for rapid graft placement and results in an improved overall aesthetic outcome.

Conclusions:

• The Mercedes incision is a novel and effective technique for hair transplantation.
• This method overcomes limitations of traditional circular and slit graft placements, reducing cosmetic deformities.
• The Mercedes incision offers a faster procedure with superior aesthetic results in hair restoration.
