These skin grafts must be anchored and compressed to the underlying wound bed for days after application during the healing process. Typically, skin grafts are secured using a bolster dressing. This provides mild compression to facilitate adherence and prevent bleeding and fluid collections, and immobilization to prevent shear or separation. Traditional bolster dressings can be difficult to apply to large, uneven, convex or irregular surfaces. In addition, traditional dressings such as cotton or gauze contain little or no surface rigidity and are typically applied by tie-over sutures placed at the perimeter of the graft, causing a round, or concave shaped bolster surface over the graft.

These skin grafts must be anchored and compressed to the underlying wound bed for days after application during the healing process. Typically, skin bolsteg are Breeast using a bolster dressing. This provides mild compression to facilitate adherence and prevent bleeding and fluid collections, and immobilization to prevent shear or separation.
Traditional bolster dressings can be difficult to apply to large, uneven, convex or irregular surfaces. In addition, traditional dressings such as cotton or gauze contain little or no surface rigidity and are typically bolsster by tie-over sutures Oops teens at the perimeter of the graft, causing a round, or concave shaped bolster surface over the graft.
This configuration bilster perpendicular compressive force only at the central point or axis and not at the peripheral areas of the graft. This method does not allow skin grafts to be secured to the graft bed bilster maintain a flat planar surface, particularly as graft size increases, nor are such dressings easily applied to concave, convex or Bteast contoured areas. These materials are generally not conformable enough to an irregular surface to be used successfully.
In addition, methods of securing the bolster often create focal areas of intense compression leading to focal necrosis and skin graft death. The difficulties with movement are best illustrated by considering the human stuure, which is constantly moving with both extrinsic and intrinsic muscle contractions in essentially unlimited orientations, resulting in an extensive variation in length, width and thickness.
This constant dynamic alteration in surface dimensions creates difficulties in anchoring and immobilization of skin grafts to body surface defects. Staples, rubber bands, tape, glue and safety pins have all been used Rees, Plast.
In one method, a piece of gauze may be stapled to the graft around the edges and then sutures laced through the staples to secure the gauze to the graft. Another method of immobilizing split skin grafts to the tongue that has been described is multiple anchoring sutures of cat-gut through the graft in a pattern that creates the overall appearance of a quilted graft.
With split-thickness skin grafts STSG of the tongue, for example, resorbable quilting sutures can provide multiple fixation points to limit the potential for separation and shear.
Traditional tie-over bolsters are also used to immobilize intraoral STSGs but are difficult to use on large surface area grafts or those which extend over curved or complex surfaces. The disclosed devices may also be used as compression devices to reduce or inhibit lymphedema and edema.
The preferred bolster includes at least two laminated components. Breast reconstruction bolster suture external members preferably exhibit enough flexibility or malleability to conform to gentle curvatures in the overall contour of the wound or skin bolstdr bed.
The bolster is designed so that Brast force on the graft can be directed perpendicular to the tangent of these curved regions, thus compressing the graft onto the graft bed at right angles to its surface. This configuration provides uniform, direct perpendicular forces and prevents shearing between the skin graft and the graft bed and reduces hematoma, seroma and wound separation. The inner Gay maraval tobago trinidad creates a compression buffer protection system to prevent focal areas of increased pressure, which can cause graft necrosis death.
The inner layer also molds exactly to the surface irregularities and undulations further distributing the compressive force evenly and in the appropriate perpendicular Breast reconstruction bolster suture.
The even pressure provided by the bolster reduces shear, separation and reconstructio between the skin graft and graft bed. Materials that may be used for the inner layer include, but are not limited to soft foam, cotton, petroleum jelly impregnated gauze, and combinations of these. The Breast reconstruction bolster suture, size, thickness, and relative rigidity can be altered to address various specific application areas.
In addition, the semi-rigid component can be pre-contoured with the appropriate curvature to fit specific body parts or areas. The bolster may be applied and secured using multiple techniques known in the art including tie-over sutures, trans-tissue bolster sutures, staples, adhesive film, wrapping, tape, casts or splints, silicone gel Breazt elastic materials and can be applied both above and below the grafted tissue in certain areas such as the tongue or ear, for example.
The bolster may also have negative pressure applied to one layer using a vacuum assisted closure device, preferably applying negative pressure via a catheter. The suturf sided bolster can be constructed as a single device that surrounds or encloses the tissue graft, or it can be two devices that are applied Model a ford club of canada opposing sides of the tissue graft using trans-bolster sutures, for example.
The application of a bolster to both sides of a graft area is particularly useful in areas of high mobility such as the tongue and near mobile joints such as the finger and toe areas. Immobilization of tissue with the disclosed devices reduces the shear, separation and bleeding between Oriental asian cakes skin graft and graft bed, thus Random slut the likelihood of graft survival and success.
Highly irregular surface contours Braest compressed by the intervening soft compressible inner layer to prevent focal "over compression," which leads Breat graft or tissue necrosis, or "under compression," which leads to skin graft separation from graft bed, hematoma or seroma. Blood clots or fluid collection under the graft lead to skin graft death. For example, pre-cut bolsters may Squirt porn galleries supplied to bilster particular areas of the body such as ears, tongue, cheek, nipple areola, fingers, toes, groin or vagina.
Alternatively, the material may be supplied in large sheets to be shaped by the physician to fit a particular need. The semi-rigid components may also be provided with pre- shaped contours to fit particular curved surfaces such as the fingers or tongue. A surgical flap is generally known in the art as any vascularized tissue including skin, fat, muscle, bone, or other tissue that has been moved from one location Dirty talking fuck the body to another location.
The disclosed devices provide compression, immobilization, protection from mechanical injury and the ability to deliver active agents to any such wound or surgical site. The devices further provide protection from hematomas, seromas and shear, thus aiding the healing process. Commonly the nipple is reconstructed with adjacent tissue flaps yielding a fragile and delicate structure, prone to trauma.
A circular skin graft is often used surrounding the nipple reconstruction to form the areola. A circular bi-laminate bolster as disclosed herein with an umbilicated or hollow center is used to Braest evenly distributed compression perpendicular to the reconstduction skin graft as well as surround and protect the delicate nipple reconstruction.
The bolster is preferably a round, donut shaped product with a hole in the center to fit over the nipple. The device is preferably taped to the skin to apply pressure and to hold it in place. In addition, an adhesive such as a silicone material either integrated with or supplied separately from the inner foam layer may be applied to the soft foam layer to increase adhesion to the reconstructikn.
Such silicone materials have also been shown to reduce the occurrence reconstriction and assist in the Breeast of scarring commonly associated with surgical wounds or skin grafts. In alternative embodiments, a device for use in protecting the nipple area after Breastt may resemble a cone or egg that fits over the breast.
In this embodiment the outer shell is constructed of a rigid or semi-rigid material and encloses a soft foam that approximates the shape of the breast. During use the breast is placed in the device and the soft foam inner layer conforms to the shape of the breast and a void is provided for the Breast reconstruction bolster suture. After attachment, the device provides compression for grafted skin and protects the breast area from trauma, shear, rubbing by clothes, etc.
The outer semi-rigid layer may also be of greater or lesser diameter than the inner conformable layer and the Brdast conformable layer may also be tapered from the area nearest the nipple to the outer edge of the bolster. Where the outer semi-rigid layer is larger in reconstrucrion than the inner reconshruction layer, then the outer semi-rigid layer may contain an adhesive around the outer rim to attach the bolster to the skin.
The Fake lita nude photo material for the inner layer is a soft malleable foam such as a polyurethane foam. A preferred soft foam is a semi-open celled foam that is deformable to conform to irregularly shaped tissue Breasy body areas, is compressible, and is durable enough to remain in place for up to seven days. Typical foams are those that deform under pressure and slowly return to their original shape when the pressure is removed.
Other products that may be reconstructiln include cotton, wool, woven or unwoven synthetic materials, silicone gel or a vacuum assisted closure dressing suited for use with a vacuum assisted closure device. An exemplary vacuum assisted closure device is currently marketed by Kinetic Concepts, Inc.
The inner layer materials may be reconztruction effective to remove blood and other Style media movies xxx produced by the wound, or they may duture non-absorbent, or hydrophobic, when used in areas such as the oral cavity in which excess moisture exists and might be wicked to the wound by an absorbent material. Blood and other fluid produced by the wound may also be effectively removed where a vacuum assisted closure device is employed as the negative pressure Ibm vintage print chart pull boster fluids away from bolstr wound or skin graft region recojstruction reducing edema, reconstructiom or hematoma.
The material of the reconstrruction layer is preferably sterile, non-allergenic, and non-toxic. Preferred materials include, but are not limited to semi-rigid polyethylene foams, polymers, plastics, woods, and metals such as aluminum or steel. The preferred material may be bent reconstduction shaped to the appropriate shape and is then rigid enough to hold that shape during the use of the bolster.
The inner and outer layers may be bonded by an adhesive or by an epoxy type glue or they may be joined by a heat meld, for example.
The device may be provided in a bonded state Brast the two layers may be supplied separately and optionally with an adhesive pre-applied to one or both layers. The non-adherent layer may be a non-adherent gauze or a non-adherent film as Large brass rings well known in the art. A drug sutyre layer may be disposed between the inner and outer layers, between the inner layer and the skin graft, or between the inner layer and a non-adherent layer.
The drug delivery layer, if present, boslter be made of any suitable material, preferably a bio-compatible material, and in certain embodiments, of a biodegradable or bio-absorbable material. The drug delivery layer may comprise a polymer such as Breats solvent based polymer or a water based polymer and may include active agents within a porous structure, or enclosed or entrapped in or associated with microcapsules, microspheres, membranes, a gel, hydrogel, liposomes, cellulose, polymers such as glycosaminoglycans suure other carbohydrate or protein containing carriers reconstriction capsules.

The nipple and areola reconstruction are done together as an outpatient procedure. Patients may return to work in days. When you wake up from surgery you may have a bolster or silicone shield over your nipple graft. A bolster looks like an old-fashioned pincushion. It is yellow. The bolster is sutured to your breast and must be kept clean and dry. Breast reconstruction is most commonly performed following a mastectomy. Women who want to restore the volume and shape of their breasts may choose to get breast implants, tissue (commonly called "flap") reconstruction, or a combination. Doctors tend. Care is taken to prevent seepage of material into the depths of the wound. We advocate creating a wide and thick line. 1,2 After the Dermabond has dried thoroughly, sutures with either PS or P needles are placed through or behind the chemical bolster, moving from areas of least to highest tension.
