The methods for reconstruction with a flap after resection of head and neck tumors have progressed since Bakamjian developed the D-P flap in 1965. During the intervening 21 years, such excellent flaps/organs as stalked muscle flaps, the free forearm flap, and the free jejunum flap have been devised. However, the fast progress of surgical techniques has brought with it a concomitant increase in the difficulty of training clinicians to apply said techniques. Therefore, we developed a spacer for use in performing microsurgical vascular anastomoses. We studied the difficulties involved in using it for patients undergoing oral reconstruction (with a forearm flap) in the treatment of oral cancer. Oral reconstruction by means of angiostomy featurs a free flap that includes anastomosis of the nourishing vessels with the transplanted vessels. This method obviously favors a more successful oral reconstruction than methods that use the conventional D-P flap or various muscle flaps. However, learning the operational technique presents a problem. This spacer is designed specifically for microsurgical vascular anastomoses. It was developed in 1983 at the Department of Head and Neck Surgery of the Cancer Institute Hospital, the 5leading author of this article. We introduced this spacer because it enhances the safety, simplicity, and reliability of microsurgical vascular anastomoses.
