The unique niche for compound flaps is their potential role for the repair of massive defects that demands the simultaneous restoration of multiple, missing tissue types. These complex flaps can be sorted into two major classes, and their subtypes on the basis of their means of vascularization are described.
What is a flap used for?
A flap is a piece of tissue that is still attached to the body by a major artery and vein or at its base. This piece of tissue with its attached blood supply is used in reconstructive surgery by being set into a recipient site (injured area onto which a flap or graft is placed).
What is flap and its types?
What are the Types of Flap Surgery? 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. Pedicled flap: Flap that has its blood supply with at least one artery and one vein.
What is a chimeric flap?
As defined by Hallock (Plast Recon Surg 117:151e, 2006), a chimeric flap consists of multiple otherwise independent flaps that each have an independent vascular supply, with all pedicles linked to a common source vessel.
What are flaps medicine?
A flap is a unit of tissue that is transferred from one site (donor site) to another (recipient site) while maintaining its own blood supply.
Is flap a surgery?
Flap surgery is a technique in plastic and reconstructive surgery where any type of tissue is lifted from a donor site and moved to a recipient site with an intact blood supply. This is distinct from a graft, which does not have an intact blood supply and therefore relies on growth of new blood vessels.
What is the difference between a skin graft and a flap?
A skin graft is the transfer of a portion of the skin (without its blood supply) to a wound. A flap consists of one or more tissue components including skin, deeper tissues, muscle and bone.

What are the different types of flaps?
There are four basic types of flaps: plain, split, Fowler and slotted.
How do you classify flaps?
Tissue Composition Classification
- Skin Flap: includes skin and superficial fascia.
- Fasciocutaneous Flap: includes skin and investing layer of deep fascia.
- Fascial Flap: includes the deep fascia only.
- Muscle Flap: include muscle only.
- Myocutaneous Flap: includes muscle and skin.
What is an alt flap?
The anterolateral thigh (ALT) flap (Fig. 22-4) is a very popular flap for lower limb reconstruction for several reasons. It is based on an area of skin and fascia on the anterolateral aspect of the thigh supplied by perforators of the descending branch of the lateral circumflex femoral artery.
How does a free flap work?
Free flap, also known as free tissue transfer, is a term for a procedure in which tissue and its blood supply (artery and vein) are surgically removed from one part of the body and transferred to another area of the body for the purpose of reconstruction.
What is a flow through flap?
Flaps have long been recognized as an essential tool for soft-tissue reconstruction. … The concept of a flow-through flap, in which both the proximal and the distal ends of the vascular pedicle of a free flap are anastamosed to provide blood flow to distal tissues, was first described by Soutar et al. in 1983.
How does flap surgery work?
A flap procedure cleans the roots of a tooth and repairs bone damage caused by gum disease. A gum specialist (periodontist) or an oral surgeon often performs the procedure. Before the procedure, you will be given a local anesthetic to numb the area where the doctor will work on your gums.
How do you do a flap?
What are axial flaps?
Definition. An axial pattern flap is a skin flap in which a direct cutaneous artery is incorporated. These arteries supply the subdermal plexus and guarantee a sufficient blood supply to the flap. The vascularity is thus better than the earlier described subdermal plexus flaps.
Does flap surgery hurt?
Most patients experience some discomfort after a flap procedure. Depending on your needs, we may prescribe pain medication or recommend over-the-counter medicine. It is important to relax after surgery, as strenuous activity may cause the treated area to bleed.
What are the side effects of flap surgery?
Some of these risks are covered below.
- Loss of the flap. Blood vessels supplying the flap may kink or get clots, leading to bleeding and a loss of circulation. …
- Problems with the donor site. After having an abdominal flap reconstruction, some women find it takes a while for the wound to heal. …
- Hernia (abdominal bulge)
Who needs flap surgery?
A flap procedure is often needed to save teeth that are supported by a bone damaged by gum disease. Gum disease usually will come back if you do not brush and floss regularly after surgery. To promote healing, stop all use of tobacco.
Which is better skin graft or skin flap?
Flaps usually heal faster than grafts. A graft is a piece of healthy skin that is removed from one part of the body and used to cover a wound elsewhere. Unlike a skin flap, a graft does not have its own blood supply. At first, the graft survives because nutrients pass (diffuse) from the wound site into the graft.
How long does skin flap surgery take?
The surgery takes 1 to 3 hours. If the graft is a large area, you may stay one or more nights in the hospital.
What are the 4 types of grafts?
Grafts and transplants can be classified as autografts, isografts, allografts, or xenografts based on the genetic differences between the donor’s and recipient’s tissues.
How do you test flap vascularity?
The presence of at least one drop of bright red colored blood on each of the three points [Figure 5] is considered as satisfactory vascularity in which case the additional pedicle is divided and the flap is primarily transferred, while taking care not to include the clamped skin.
What is free flap failure?
Free flap failure was defined as complete necrosis of the flap. There were 13 documented flap failures with complete necrosis of the flap requiring debridement. Seven patients underwent repeat free microvascular tissue transfer.
What is a flap plastic surgery?
Flap surgery involves the transfer of a living piece of tissue from one part of the body to another, along with the blood vessels that keep it alive. It may be used for a variety of reasons, including breast reconstruction, open fractures, large wounds, and, in rare cases, for improving a cleft lip and palate.
Do fighter jets have flaps?
In the case of a fighter jet the wing is in general a delta wing without flaps, so in order to reduce the speed for landing they have to increase the angle of attack to augment the trail without loosing too much lift.
What is flap 3 flap full landing?
Normal flaps for landing is Flap 3 but, at the discretion of the pilot in command, up-to a maximum of 2 percent landings can be performed with Flap Full. People tend to avoid risk when a positive frame is presented but seek risks when a negative frame is presented, Singh says in his blog Mindfly.
What are the 4 main types of flaps on a plane?
Flaps come in 4 main varieties: plain, split, slotted and fowler (Fig. 3). The plain flap is the simplest of the four varieties. It works by lowering the aft portion of the wing, increasing its camber, which in turn causes the wing to produce more lift.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
