Prefabricated vertical myocutaneous flap of the nose in facially burned patients.

In facially burned patients, a simple and effective technique is described for reconstruction of deformities of the lower third of the nose. The first stage consists of replacing the dorsal scarred skin with a skin graft from the buttocks or other area. The second stage is a vertical columella-based prefabricated flap that is outlined beginning near the tip of the nose and extending superiorly to the glabellar region. This flap is raised with the underlying muscle as a composite tissue, transposed to the defect, and sutured to the vestibular mucous membrane or the integument of the remaining portions of the nose at the alar rim. This very well vascularized vertical prefabricated myocutaneous flap can cover a cartilage graft taken from the ear to reconstruct an alar rim. The donor site is closed by undermining the nasal skin laterally on each side and suturing the edges at the dorsum to leave an acceptable midline scar. In patients for whom a nasolabial flap or other technique is not suitable or is impossible, this new and simple technique may be used successfully.

Reconstructing the breast mound employing a secondary island omental skin flap.

We have shown in an initial animal study that omentum will adequately vascularize a skin flap and allow transfer of this tissue composite for use in surgical reconstruction of the breast. Based on this experimental procedure, a technique employing a two-stage operation has been developed and used in 21 female patients in reconstruction of the breast after radical mastectomy. In the first stage, the omentum, attached to one gastroepiploic artery and vein, is exteriorized to the subcutaneous tissue of the lower abdominal wall. In the second stage, the distal omentum, now vascularizing the overlying skin and soft tissue, is moved as a secondary island flap to the anterior chest wall to complete the breast reconstruction. In all but 1 of our 21 patients who have been followed for 1 to 8 years, reconstruction of large defects, including the chest wall, breast mound, and infraclavicular axillary fold depression, was performed without use of a prosthesis. In one patient, there was complete necrosis of the flap due to vascular impairment; there were three instances of delayed healing and a significant but partial loss of the flap in one patient. All complications were encountered in the first 10 patients of the series during the time the technique was being refined.

Utilization of a composite island flap employing omentum in organ reconstruction: an experimental investigation.

New methods for the reconstruction of the ear, nose, and breast using omentum to vascularize appropriate tissue composites of skin, bone, and cartilage are described. The initial investigation demonstrated that it is possible to obtain an island composite flap with omentum-costal cartilage-skin flap and preserve cartilage viability inside the omentum. The ear and nose were reconstructed in two stages. In the first stage, the appropriately carved cartilage and/or bony framework was covered with omentum and a skin graft, leaving the tissue composite buried subcutaneously. In the second stage, the newly reconstructed organ was exteriorized and diagnostic studies were done. The breast reconstruction was undertaken in two stages, first creating an omental island skin flap and subsequently either implanting a standard prosthesis under the flap or transferring the entire composite superiorly to better simulate the clinical reconstruction wherein the lower abdominal skin with omentum would be moved to the anterior chest. In each reconstruction a variety of diagnostic studies, including intravenous fluorescein dye, radioactive isotope uptake, and microangiography, were performed.

Secondary musculocutaneous flap: an experimental study.

In four dogs, eight secondary musculocutaneous flaps were created by the vascularization of skin flaps with transposed sartorious muscle. All skin flaps demonstrated excellent viability on clinical follow-up, with vascularity confirmed by fluorescein dye, microangiography, and histologic studies. Potential clinical uses of this method are discussed.

Development and utilization of a composite island flap employing omentum: experimental investigation.

In 39 pigs, four varieties of secondary island flaps were created using omentum as a carrier. This study demonstrates that: 1. Skin grafts (split- or full-thickness), when grafted to omentum, can be transformed into an "island flap," and the free transfer of this flap with microvascular anastomosis is feasible. 2. A skin flap, a combined skin flap, or both and subjacent muscle could be vascularized with omentum to obtain an omental island skin flap or an omental island musculocutaneous flap and transferred as already described. 3. Three varieties of secondary island osteocutaneous flaps were created using the omentum. Of these flaps, eight successfully underwent microvascular transfer. Bone vascularity and incontinuity viability were demonstrated by employing a variety of standard diagnostic techniques, including 99mTc-pyrophosphate tetracycline labeling, microangiography, and histologic sectioning. In addition to the many recognized advantages of a free living bone graft in reconstructive surgery, other benefits of this new kind of island composite flap include its unlimited size, minimal donor deformity, and ease of transfer. We have demonstrated that omentum can be used to vascularize skin, a skin flap, and either tibial, costal, or iliac bone graft to obtain a secondary island flap. The clinical uses of these flaps promise a new and exciting horizon in reconstructive surgery.

A mastopexy technique for mild to moderate ptosis.

A surgical technique for mastopexy, done through a circumareolar incision and leaving no noticeable scar, is described. The skin brassiere is undermined and a rotation-invagination and suture maneuver are performed which simultaneously augments the projection of the breast and elevates the nipple-areola complex. The overlying skin contours itself to the reshaped breast. The favorable results obtained in six patients with this new method are encouraging and further use in selected patients is planned.

New capillary bed formation with a surgically constructed arteriovenous fistula.

This study on 24 rats has demonstrated that neovascularization of the skin through an arteriovenous fistula is possible. A vascular bed can be created by the use of long interpositional vein grafts. An arteriovenous fistula in the shape of a loop could not only provide vascularity to create a skin flap of unlimited size but could possibly vascularize a digital replantation with severely damaged vessels and provide enough additional vascularity to facilitate the take of bone grafts and tissue composites.
