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.

Evaluation of anastomotic techniques in the experimental transfer of free skin flaps.

Vascularized groin flaps were transferred to the contralateral side by various microvascular anastomotic techniques. There was no statistical difference between the results of end-to-end and end-to-side anastomoses, when the same sized vessels were compared. However, significant differences existed when vessels smaller than 0.5 mm in diameter were anastomosed.

Experimental esophageal reconstruction in rats, with a free groin flap.

The reconstruction of a functioning esophagus with a free groin flap was performed successfully in 10 rats. A technique is described for the experimental anastomosis of vessels with a diameter of 0.5 mm or less. We also describe a modification of a method to convert a hairy flap before transfer into a hairless one.
