What is a pedicled perforator flap?

1 An option that has been popularized in the past two decades are pedicled perforator flaps. A perforator flap is a cutaneous or subcutaneous flap that is vascularized by one (or more) perforating vessels arising from underlying deeper vessels.

What does Fasciocutaneous mean?

Fasciocutaneous flaps are tissue flaps that include skin, subcutaneous tissue and the underlying fascia. Including the deep fascia with its prefascial and subfascial plexus enhances the circulation of these flaps. They can be raised without skin and are then referred to as fascial flaps.

What is a rotational skin flap?

A rotation flap is a semicircular flap of skin and subcutaneous tissue that rotates about a pivot point into a defect. The donor site is typically repaired with wide undermining and direct, layered closure. The vector of greatest tension is directed from the pivot point outward to the defect’s furthest radial point.

What is propeller flap?

By the definition of the “Tokyo” Consensus on Propeller Flaps from 2011, a propeller flap is an island flap that reaches the recipient site through an axial rotation of more than 90°. It can be thought of as a propeller with 2 blades of unequal length with the perforator forming the pivot point.

What is the meaning of perforator?

: one that perforates: as. a : an instrument used to perforate tissue (as bone) b : a nerve or blood vessel forming a connection between a deep system and a superficial one.

What is a perforator flap reconstruction?

Perforator flap surgery is a technique used in reconstructive surgery where skin and/or subcutaneous fat are removed from a distant or adjacent part of the body to reconstruct the excised part.

What is Z plasty surgery?

Z-plasty is a plastic surgery technique that is used to improve the functional and cosmetic appearance of scars. With this technique, it is possible to redirect a scar into better alignment with a natural skin fold or the lines of least skin tension. Contracted scars may be lengthened with this technique.

What is a keystone flap?

The keystone flap consists of two V-Y advancement flaps in opposing directions. The movement of these advancement flaps leads to availability of extra tissue adjacent to the defect so as to facilitate primary approximation of skin edges.

How long does it take for a skin flap to heal?

The donor area of partial thickness skin grafts usually takes about 2 weeks to heal. For full thickness skin grafts, the donor area only takes about 5 to 10 days to heal, because it’s normally quite small and closed with stitches. At first, the grafted area will appear reddish-purple, but it should fade over time.

What are the four main types of flaps?

Here’s how they work.

• 1) Plain Flaps. The most simple flap is the plain flap.
• 2) Split Flaps. Next up are split flaps, which deflect from the lower surface of the wing.
• 3) Slotted Flaps. Slotted flaps are the most commonly used flaps today, and they can be found on both small and large aircraft.
• 4) Fowler Flaps.

What is a transposition flap?

Transposition flaps, also called lifting flaps, recruit noncontiguous donor tissue that is incised and lifted over intact skin and placed into the primary defect.

How do you summon a perforator?

Spawn. The Perforators do not spawn on their own. The player can summon them manually with Bloody Worm Food or by killing a Perforator Cyst while in The Crimson.

When did Ponten invent the fasciocutaneous flap?

Ponten first described fasciocutaneous flaps in 1981.Previously, most lower limb flaps were based on the concept of random skin flap design, thus were limited by a certain length-to-width ratio (usually 1:1 in the lower extremity).

What is the definition of a fasciocutaneous flap?

A fasciocutaneous flap can be composed of any or all of the tissue layers found between the skin and deep fascia. By this definition, Cormack and Lamberty were further able to contract all skin flaps into a tripartite system that included direct cutaneous ( sic . axial), musculocutaneous , and fasciocutaneous flaps.

Are there different types of musculocutaneous perforator flaps?

The Type VI “musculocutaneous perforator flaps” resembled traditional myocutaneous flaps. The six distinct deep fascia perforators according to Nakajima et al. A different type of fasciocutaneous flap can be sustained by each discrete type of perforator.

Why was the classification of flaps so easy?

The classification of flaps in the beginning was relatively easy, since they could be distinguished from one another only according to how they were constructed.
