Experience with a surgical technique of microvascular anastomosis for free tissue transfers and digital replantations has been applied in 184 cases, and demonstrates that complications such as total flap necrosis are avoidable by experience and technical skill.
A successful free groin flap transfer to the arm in a 3-month-old baby is described. The vessels were large enough for microvascular anastomosis and we believe that there is no minimum age restriction for free flap transfer.
A clinical operative technique for free muscle transplantation by microneurovascular anastomoses is presented. Two cases of free transfer of the gracilis muscle for dynamic reconstruction of facial paralysis are described, including a follow-up study with electromyography, light microscopy, and electron microscopy. We feel this new technique will have a wide range of application in reconstructive surgery.
We report the transfer of a free musculocutaneous compound flap, including the gracilis muscle, in one stage by microvascular surgery. The advantages of this free flap are discussed.
Since 1973 we have transferred various kinds of free flaps by microvascular surgery. In hand reconstruction, the free flap is less often required than in repairs of other sites, such as the leg. However, the importance of restoring sensibility in the hand is evident. Recently, we have transferred thin dorsalis pedis flaps as sensory free flaps in 5 cases of hand reconstruction, and we describe our experiences with them.
Free omental transplantation with vascular anastomosis was attempted in three clinical cases as a new method of treatment for chronic osteomyelitis. The bone cavity produced by debridement was completely eliminated by the transplanted omentum. Furthermore, the omentum, because of its biological characteristics, formed good vascular anastomoses with the adjacent bone tissue. Although sufficient time has not yet elapsed to prove the existence of healthy bone regeneration and therefore, further evaluation for a longer period is necessary, this therapeutic method would seem to have considerable potential in the treatment of chronic osteomyelitis.
In this article we have described general considerations relative to free flap transfers, introduced our operative technique of free flap transfers and outlined some of our representative cases. We also set forth the advantages and disadvantages of free flap transfers as we have experienced them.

The operative technique of free groin flap transfer is described and some typical results presented. The overall complete success rate in 47 cases was 80 per cent, but complete necrosis only occurred in II per cent of the transferred flaps.
By studying the vascular base of flaps raised from cadavers we obtained a basic knowledge of free groin flaps for clinical application. The method of selection of the nutrient vessels in 70 free groin flaps based on this knowledge has been described.

We report two successful transfers of free groin flaps to the lower legs of children. We believe this method can be safely applied and can often take the place of distant pedicled flap transfers in children.

We have used free forearm flaps for closure of various intraoral and oropharyngeal defects after radical ablation of tumors. A problem remained, however, in that split-thickness skin grafts required to close the forearm defect had to be obtained from other areas. To avoid this disadvantage, we de-epithelialized forearm flaps and the donor defects were closed with the split-thickness skin obtained from flap de-epithelialization. As a result of this procedure, unnecessary scarring has been avoided and postoperative management has been simplified. Such complications as flap loss, fistulae, or scar contracture have not occurred with greater frequency than is seen in normal circumstances. The de-epithelialized forearm flap procedure is explained. Histological findings concerning the de-epithelialized forearm flap are described, and the advantages of this method stated.
