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.
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".
A forehead is called short when it is shorter than 4.5 cm. When using the forehead flap on a short forehead, there are multiple ways to get the length that is needed. [1] [3] First, the turning point of the flap can be moved down, so that the base of the flap is closer to the nasal defect and a shorter flap can be used to reach the nasal defect ...
Flaps can contain many different combination of layers of tissue, from skin to bone (see § Classification). The main goal of a flap is to maintain blood flow to tissue to maintain survival, and understanding the anatomy in flap design is key to a successful flap surgery. [2] The distribution of the blood vessels in the skin of the sole of the ...

This flap borrows tissue from the cheek and lip of the uninvolved side of lip with the defect. It restores lip continuity in a one-stage procedure, but has some disadvantages, including an adverse effect on sensation, small size of mouth, and difficulty matching up the vermilion border of the central lip with the lateral lip.
The transposition of two triangular flaps. The incisions are designed to create a Z shape with the central limb aligned with the part of the scar that needs lengthening or re-aligning. The traditional 60° angle Z-plasty will give a theoretical lengthening of the central limb of 75%. [1] Single or multiple z-plasties can be used.
In the temporomandibular joint, the initial mouth opening occur by rotation, within the inferior cavity of the joint. [14] The TMJ rotates around a fixed axis within the condyle, with no antero-inferior translation. [14] The maximum jaw opening with this rotation movement is indicated as 'R' on the Posselt's envelope of motion.
