Local flaps are created by freeing a layer of tissue and then stretching the freed layer to fill a defect. This is the least complex type of flap and includes advancement flaps, rotation flaps, and transposition flaps, in order from least to most complex.
A rotation flap is a semicircular skin flap that is rotated into the defect on a fulcrum point. Rotation flaps provide the ability to mobilize large areas of tissue with a wide vascular base for reconstruction. The flap must be adequately large, and a large base is necessary if a back-cut will be needed to lengthen the flap.
Dufourmental flap: Cutaneous: Rotation/Transposition: Estlander flap: Cutaneous: Transposition: Labial commissure of mouth defects Fibular flap: Osteocutaneous: Free flap: Mandible reconstruction Gastrocnemius flap: Muscle: Interpolation: Open tibial fractures: Hatchett design flap: Cutaneous: Advancement: Forehead excisions/defects Inferior ...
This includes pedicled flaps as the trapezius or supraclavicular flap or tissue expansion of nearby regions. Alternatively, the Crane principle, as described by Millard in 1969, can be used. A healthy part is used to resurface the defect and when this flap takes, the skin is returned to its original site leaving the subcutaneous tissue on the ...
The subgroup of pedicled perforator flaps, transferred in the defect by rotation is the so-called "propeller flap". Confusion concerning definition, nomenclature and classification of propeller flaps led to a consensus meeting similar to the "gent consensus meeting”. The consensus that was reached is named "the tokyo consensus".
The rotation-advancement procedure for cleft lip repair, also known as the Millard repair, is designed to create a softer, more natural-looking lip. Surgery performed prior to the Millard procedure involved pulling both sides of the cleft lip together resulting in a tightly closed upper lip.
Chimpanzee Ham, who flew America's first suborbital space flight on Jan. 31, 1961, toasts NASA's anniversary by sampling a Skylab space drink on Oct. 01, 1973 at the National Zoo in Washington D.C.
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).
