What is an O to T flap?
What is an O to T flap?
The O-to-T is a workhorse flap for defects on the chin and is used here because a standard linear closure would have run out of skin real estate, going into the lip – which would not have been desirable for the patient.
What is the medical term flap?
A flap is a unit of tissue that is transferred from one site (donor site) to another (recipient site) while maintaining its own blood supply. Flaps come in many different shapes and forms. They range from simple advancements of skin to composites of many different types of tissue.
What is Burow’s triangle?
The term “Burow’s triangle” is defined as a triangle of skin and subcutaneous fat excised so that a pedicle flap can be advanced without buckling the adjacent tissue. Burow was a passionate advocate of open wound treatment.
What is a surgical free flap?
“Free flap,” also known as “free tissue transfer,” is a term for a procedure in which tissue and its blood supply (artery and vein) are surgically removed from one part of the body and transferred to another area of the body for the purpose of reconstruction.
What is rhomboid flap?
The rhomboid (Limberg) flap is a transposition flap that, like the bilobed flap and the Z-plasty, depends on the pliability of the adjacent skin, which can be determined by pinching various areas between the thumb and forefinger (2).
What is an advancement flap?
Advancement flaps are random-pattern flaps frequently used in the reconstruction of surgical defects on the face after the removal of skin cancer. Proper design and meticulous execution is crucial in achieving reproducible esthetic results.
What are the types of flaps?
There are four basic types of flaps: plain, split, Fowler and slotted.
How do you classify flaps?
Multiple classifications have been described, but, in general, flaps for reconstruction are classified based upon the type of blood supply (ie, random, axial), proximity of the donor tissue to the recipient (ie, local, regional, distant), and tissue composition (eg, musculocutaneous, fasciocutaneous) [1].
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.
How many types of free flaps are there?
Four types of free flaps have been used in finger reconstruction from the ipsilateral extremity, including arterialized venous flap (AVF) [13], superficial palmar branch of the radial artery (SPBRA) flap [14], posterior interosseous perforator flap (PIPF) [15], and ulnar artery perforator free (UAPF) flap [16].
How long does it take to recover from free flap surgery?
Generally, recovery after fibula flap surgery takes three to four weeks and includes 10 to 14 days in the hospital. The patient may move in a no weight-bearing fashion on the second postoperative day. The splint is removed and the skin graft is assessed on the fifth postoperative day.
What is Limberg flap?
The Limberg flap is a series of communicating equilateral triangles. All angles are 60°, which means that every side of both the defect and the flap is equal in length. This orientation creates a flap that is the same size as the defect to be excised.
How to choose the right flap for your defect?
A cookbook approach to choosing flaps based on anatomic locations or other characteristics of defects is suboptimal. Each defect should be individually considered from all aspects and then selection of the most suitable flap is made with a conscious effort to address all reconstructive challenges.
What is the difference between T-plasty and V-Y and Y-V flaps?
Like the T-plasty, V-Y and Y-V advancement flaps do not require two parallel incisions to create the flap (see discussion of these flaps in Chapter 6). The V-Y advancement flap is unique in that the V-shaped flap is not stretched or pulled toward the recipient site but rather achieves its advancement by recoil or by being pushed forward.
Does the flap advance during movement of the flap?
Most local cutaneous flaps used in the head and neck have some component of advancement during movement of the flap to the recipient site. An example is the paramedian interpolated forehead flap.
What is a double tangent advancement flap?
Double tangent advancement flaps (DTAFs) DTAFs displace both Burow’s triangles along parallel tangents (see Fig. 147.4 ). Therefore, these flaps are typically peninsular in configuration with an isolated vascular base at the distal ends of the tangents.
