At the end of 2002, a 3D whole-body white light scanner was introduced into a cosmetic surgery practice in Norfolk, Virginia. The stated purpose was to investigate this device as an aid for evaluating body contouring procedures. For the first time, the surgeon could pre-operatively scan a patient, measure "body areas of interest," and examine in detail the patient's 3D body contours to help plan for the pending surgical procedure. Multiple, custom designed measurement templates were then

Post-operative scans of the patient would then be taken periodically, and measured with the same measurement templates. The difference in measurements, including volume and surface area document the physical changes of patient's body resulting from the procedure. Many cosmetic surgery patients return for additional procedures over the course of years. The patient's 3D digital archive provides the surgeon with the ability to consult previous 3D body models and evaluate the measurement changes of past procedures. These unique insights, combined with a current 3D scan and traditional medical information form a contiguous and robust foundation for assessing the pending surgical procedure. Methods Three case examples are presented. Case 1 considers multiple cosmetic procedures performed in a close succession and the 3D scans and measurement templates used for pre-operative and postoperative evaluation. Case 2 presents an example 3D body scans of sequential cosmetic surgical procedures to replace and rebuild the left and right breasts of a subject. Case 3 involves multiple cosmetic procedures performed on the same patient over a period of years. In each case, the patient's 3D digital archive played an important role in documenting each surgical procedure and provided a platform to evaluate the contours of the patient for the pending surgery. Discussion A 3D whole-body scan is an independent entity. It represents the accurate physical appearance of the subject standing in the scan chamber as of the date and time of scan acquisition. A cosmetic surgery patient may undergo multiple procedures at once, such as breast reduction and abdominoplasty. The result of each procedure can be measured by applying separate customized measurement templates to the post-operative 3D body model. The patient may also undergo a sequence of procedures over time. Each post-operative 3D body model can be evaluated independently. The entire set of preoperative and post-operative 3D body scans form a historical 3D digital archive and can be appended to the traditional patient medical record. Conclusion The utility of a 3D whole-body scanner is in its ability to create an accurate 3D body model of the subject within the scan chamber, thereby creating a permanent 3D record once stored. A "clean" 3D scan documents the subject's physical body. Measurements can be extracted at any time as appropriate, but the archived 3D body model is the important record. Subsequent body scans can be measured and compared to the initial body scan. Many cosmetic surgery procedures result in immediate physical changes to the body. Each post-operative scan documents these changes. Successive post-operative scans form the patient's 3D digital archive. This archive can serve as the basis for further surgical planning, validating surgical results, or can be used as a tool for independently assessing surgical outcomes.
