The island pedicle flap uses an island of skin that is detached from its epidermal and dermal attachments while retaining its vascular supply from an underlying pedicle to repair a cutaneous defect. What is Pedicled flap?
Listen to pronunciation. (PEH-dih-kul …) A type of surgery used to rebuild the shape of the breast after a mastectomy. Tissue, including skin, fat, and muscle, is moved from one area of the body, such as the back or abdomen, to the chest to form a new breast mound.
What is a submental island flap?
The submental island flap is an axial patterned flap based on the submental artery. The submental artery is a consistent branch of the facial artery. … The artery then gives off a variable number of perforators that pierce the platysma muscle and supply the subdermal plexus. What is a rotational skin flap?
Rotation flaps are local flaps that use adjacent tissue rotated in an arc to close a defect. They are nearly always random flaps composed of skin and subcutaneous tissue devoid of segmental vessels. They ultimately rely on perforators that course superficially to supply the dermal and subdermal plexuses.
What is myocutaneous flap?
Myocutaneous flaps are compound flaps with a solitary vascular supply incorporating skin, subcutaneous tissue, fascia, and the underlying muscle. … Once a pedicled or free-tissue transfer is performed, the newly transferred flap begins to incorporate into the surrounding tissue. 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.
Frequently Asked Questions(FAQ)
What is the difference between flap and graft?
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.
Is skin transplant possible?
A skin graft is a surgical procedure in which a piece of skin is transplanted from one area to another. Often skin will be taken from unaffected areas on the injured person and used to cover a defect, often a burn.
What is a radial forearm free flap?
A radial forearm free flap is one way of filling a hole which is left when a cancer has been removed. It is one of the most common ways of replacing tissue in the head and neck, particularly after mouth cancers have been removed.
What is a submental artery?
The submental artery is a branch of the facial artery after it exits from the submandibular gland. It runs over the mylohyoid and below the mandible. It continues either superficial or deep to the anterior belly of the digastric muscle. … The facial vein provides venous drainage.
What are the different types of flaps?
What is cheek advancement flap?
The cheek rotation advancement flap is one of the local flaps that reconstructs the face and is used to reconstruct the cheeks or the wide lower eyelid defect. It is also used for reconstruction of medial or lateral canthal defects because of its flexibility and easily manipulated treats .
How long do skin flaps take to heal?
Keeping the site moist with the above procedures will hasten healing and provide you with the nicest scar possible. Do not wear make up over the incisions or flap until the sutures are removed (or have dissolved), and a thin layer of new skin covers the area. This usually takes 7 to 10 days.
What is microvascular flap?
This technique involves harvesting flaps of healthy tissue — where the tissue is not as important — with the blood supply from remote sites in the body. The tissue is then transferred to the recipient wound bed, where it is much more useful in reconstructing the affected area of the head and neck.
What are muscle flaps?
The muscle flap uses only muscle for defect coverage. It is used primarily to provide a well-vascularized soft tissue that is relatively resistant to infection, helps wounds heal, and offers a vascularized surface for skin grafts. The muscle flap is commonly used to eradicate infection and to revascularize bone.
What is free flap surgery?
A type of surgery used to rebuild the shape of the breast after a mastectomy. A tissue flap, including blood vessels, skin, fat, and sometimes muscle, is removed from one area of the body, such as the back or abdomen. It is then reattached to the chest to form a new breast mound.
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 is the anterolateral thigh?
The anterolateral thigh flap lies on the axis of the septum dividing the vastus lateralis and the rectus femoris muscles. The flap is outlined on the axis of the anterior superior iliac spine and the lateral patella. … This branch enters the flap at the superior aspect, and can be traced proximally to provide length.
How is flap surgery done?
dentists can perform a flap procedure to stop the progression of gum disease. It involves incising the gums and temporarily pulling the tissue away from the teeth to treat the roots and jawbone directly. dental practice provides multiple forms of anesthesia and sedation to ensure your comfort during the procedure.
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.
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.
Do skin grafts grow back?
A partial thickness (or split thickness) skin graft is where the epidermis and a part of the dermis layer is used. The skin is usually taken from the thigh, buttock or upper arm. Skin will grow back in this area.
Is Skin grafting major surgery?
Skin grafting involves removing damaged or dead skin tissue and replacing it with new, healthy skin. Skin grafting is major surgery with serious risks and potential complications. You may have less invasive treatment options.
Do skin grafts grow hair?
After your graft heals, you may need to use lotion to keep the skin moist. The skin graft may not grow hair.
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.
