What is a pedicle graft?
A pedicle graft—sometimes called lateral pedicle graft–is one of the options used for gum grafts. In a pedicle graft, the gum tissue is moved from nearby the affected tooth to cover the exposed area. This has the advantage that it does not require surgery in a donor area.
What is the pedicle of a free flap?
When the TRAM flap is a pedicle flap, it remains attached to its blood supply, with the tissue surgically tunneled underneath the skin to the breast region. When the TRAM flap is a free flap, the tissue is detached and cut away from its blood supply before being transferred.
What is the difference between a skin graft and skin flap?
A graft is just the skin without a blood supply, whereas a flap is transferred with its blood supply intact. With a flap, larger amounts of tissue can be used, including muscle if required. Some reconstructions need both a flap and a graft.
Is a pedicle flap a local flap?
This is known as a local flap. It may be described based on its geometric design, be advanced, or both. Pivotal (geometric) flaps include rotation, transposition, and interpolation. Advancement flaps include single pedicle, bipedicle, and V-Y flaps.
What does pedicle mean in medical terms?
A pedicle is a stem or stalk of tissue that connects parts of the body to each other. The brain has many pedicles (such as the cerebral pedicle) that connect areas of the brain to each other.
What is a pedicle in the spine?
Pedicles. Each vertebra has two cylinder-shaped projections (pedicles) of hard bone that stick out from the back part of the vertebral body, providing side protection for the spinal cord and nerves. The pedicles also serve as a bridge, joining the front and back parts of the vertebra.
What is a vascular pedicle?
Plain radiograph The vascular pedicle width (VPW) is the distance between parallel lines drawn from the point at which the superior vena cava intersects the right main bronchus and a line drawn at the takeoff of the left subclavian artery from the aorta.
Is a free flap a graft?
The raw external surface of the free flap is skin-grafted. At a second stage 5 to 6 weeks later, the skin graft and subcutaneous fat of the free flap are removed, and formal nasal reconstruction with cartilage grafting and a paramedian flap is carried out.
What are the three types of skin grafts?
There are 3 main types of graftsthat are used to cover wounds: Split-thickness skin grafts, full-thickness skin grafts and composite grafts. Each of them has specific indication and has a unique technique for harvesting.
Where is the pedicle located?
Pedicle. The pedicle is a short projection of bone that comes directly off the back of the vertebral body. The pedicle lies between the back of the vertebral body and the transverse process. There are two pedicles per vertebra, one on each side.
What is pedicle of organ?
Pedicle definition (biology) A small stalk or stalklike structure, especially one supporting or connecting an organ or other body part. noun. 1. 1. A slender footlike or stemlike part, as at the base of a tumor.
Are pedicle screws permanent?
The pedicle screws have all but replaced approved methods of spinal stabilization such as wires, rods and hooks. The screws can either be permanent or temporary.
How do you measure vascular pedicle width?
The vascular pedicle width is measured by 1, dropping a perpendicular line from the point at which the left subclavian artery exists the aortic arch and 2, measuring across to the point at which the superior vena cava crosses the right mainstem bronchus.
What is a muscle flap?
The muscle flap uses only muscle for defect coverage. It is used primarily to provide a well-vascularized soft tissue that is relatively resistant to infection, helps wounds heal, and offers a vascularized surface for skin grafts. The muscle flap is commonly used to eradicate infection and to revascularize bone.
When is flap surgery required?
A flap procedure is typically recommended for patients with moderate to severe gum disease, or periodontitis, that has not responded to non-surgical treatments such as scaling and root planing. This treatment can remove built-up plaque and tartar around the roots and restore the health of gum tissue.
How long does it take to recover from flap surgery?
It can take about 6 to 8 weeks to recover from DIEP flap reconstruction surgery. Your doctor may recommend that you wear a compression girdle for up to 8 weeks after surgery.
