What is the purpose of a flap graft?
Flap surgery involves transporting healthy, live tissue from one location of the body to another – often to areas that have lost skin, fat, muscle movement, and/or skeletal support.
What is flap grafting?
Flap surgery involves a piece of tissue that still receives blood supply because it’s attached to the body by a major artery and vein or at its base. This piece of donor tissue is used in reconstructive surgery by being set into the recipient site (injured area onto which a flap or graft is placed).
What is a rotation flap surgery?
A rotation flap is a semicircular flap of skin and subcutaneous tissue that rotates about a pivot point into a defect. The donor site is typically repaired with wide undermining and direct, layered closure. The vector of greatest tension is directed from the pivot point outward to the defect’s furthest radial point.
What is a VY flap?
A V-Y flap is a modified advancement flap that is used for the repair of small and medium size cutaneous defects. It has the advantage of a robust vascular supply and a reliable healing pattern.
What is an interpolated flap?
An interpolated flap is a two-stage technique in which the base of the flap is not directly adjacent to the recipient defect. These flaps are used when insufficient tissue or mobility in nearby skin prevents the coverage of a surgical defect with primary closure or an adjacent flap.
What are the different types of flaps?
There are four basic types of flaps: plain, split, Fowler and slotted.
How many types of flaps are there?
Flaps are of two main types, free flaps and pedicled flaps. Free flap: The flap with its blood vessel is disconnected and then attached to a blood vessel at a recipient site.
How do you do a rotational flap?
The procedure involving the classic rotation flap can be thought of as closure of a triangular defect. The defect can be visualized as a portion of a much larger circle. By cutting along the arc of the circle, tissue is freed to rotate into the defect.
What is a karydakis flap?
The Karydakis flap procedure is a safe treatment alternative for the surgical treatment of sacrococcygeal pilonidal sinus disease owing to the associated low complication rate, short hospital length of stay, rapid healing, and a high patient satisfaction rate.
What is a Limberg flap?
A Limberg flap operation is a procedure for people who have either extensive or recurrent pilonidal disease. In the operation, a diamond-shaped incision (cut) is made to remove the affected skin and underlying tissue. Another incision is made in the skin to free up tissue from the buttock next to it.
How are flaps lifted and transposed in plastic surgery?
Even though the flap motion is termed transposition, and indeed the flap is lifted and transposed over adjacent tissue, a primary motion of the flap is rotation based on a fixed pedicle. Elevation of the flap by closure of the donor defect does not eliminate the limitation of the rotating movement.
What are the different types of transposition flaps?
The prototype of this flap group is termed the rhombic design.2–7Other commonly utilized transposition flaps include the banner or unilobed flaps such as the single-staged nasolabial flap, the bilobed flap, the trilobed flap, and the 30° angle flap.
What are the principles of flap design in dental implantology?
This article discusses the principles of flap design in dental implantology in an effort to summarize techniques to aid practitioners with optimal procedure selection. Principles Principle 1:New scalpel blades and sharp peri-osteal elevators are essential for making incisions and elevating flaps to protect the viability of the mucosa.
What are the final scars of a transposition flap?
The flaps’ final scars are geometric broken lines that may be less noticeable than simpler long linear closures. This geometric broken line scar may also be thought of as a disadvantage of transposition flaps, since all of the flap’s incision lines cannot be placed directly within relaxed skin tension lines.
