title: Double-exposure duplication of preoperative and postoperative 2 X 2 transparencies.
abstract: Before and after photographs in plastic surgery are an essential part of the patient's record. They also provide visual data to supplement both primary and continuing education lectures. When successive photographs are used in lectures, a sharp visual memory is required to compare effectively the preoperative and postoperative photograph. The method presented in this article uses a specially constructed frame used as an accessory for one of the common commercial slide copiers. This device makes it possible to copy, duplicate, and frame preoperative and postoperative 2 X 2 transparencies onto a single 2 X 2 transparency without any additional work on the original, such as framing, cutting, and remounting. This technique leaves the original preoperative and postoperative 2 X 2 transparency slides intact for possible use elsewhere in the same lecture or subsequent lectures on the same subject.
