Flap surgery is a technique in plastic and reconstructive surgery where tissue with an intact blood supply is lifted from a donor site and moved to a recipient site. Flaps are distinct from grafts, which do not have an intact blood supply and relies on the growth of new blood vessels. Flaps are done to fill a defect such as a wound resulting ...
Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between identical twins.
The skin layers are replaced with a paramedian forehead flap, but, if forehead skin is unavailable, the alternative corrections include the Washio retroauricular-temporal flap and the Tagliacozzi flap. The nasal skeleton is replaced with a rib-graft nasal dorsum and lateral nasal wall; septal cartilage grafts and conchal cartilage grafts are ...
A forehead flap is usually required if the nasal defect is larger than 1.5 cm, requires replacement of support or lining, or if it is located within the infratip or columella. [4] If the defect is small and superficial it can be resurfaced with a skin graft or it can heal by secondary intention. [4]
An example of "free flap" could be a "free toe transfer" in which the great toe or the second toe is transferred to the hand to reconstruct a thumb. [1] For all "free flaps", the blood supply is reconstituted using microsurgical techniques to reconnect the artery (brings blood into the flap) and vein (allows blood to flow out of the flap).
The SECT graft is a sort of hybrid procedure that combines the pedicle flap with the free gingival graft and enjoys the benefits of both. Pedicle flaps alone, such as the coronally advanced flap , frequently suffer from retraction and muscle pull.
Spinal fusion surgery involves inserting bone or a bonelike material into the space between two spinal bones, then connecting the grafts and the bones with metal plates, screws or rods.
Skin grafting, a type of graft surgery, involves the transplantation of skin without a defined circulation. The transplanted tissue is called a skin graft. [1] Surgeons may use skin grafting to treat: extensive wounding or trauma; burns; areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans [2]
