ABSTRACT
<p><b>OBJECTIVE</b>To investigate the long-term changes of expanded skin after transplantation.</p><p><b>METHODS</b>The expanded skin in dogs at 0 week, 3 weeks, 6 weeks, 3 months and 6 months after transplantation was observed through areas, histomorphological, electron microscopic, collagen content, biomechanical, and immunohistochemical methods.</p><p><b>RESULTS</b>The expanded skin was close to the control groups in all observations.</p><p><b>CONCLUSION</b>The biological changes after expansion remain in 3 months. The expanded skin will gradually recover to normal in 3-6 months. It is similar to a wound repair process.</p>

<p><b>OBJECTIVE</b>To investigate the complications in 16 patients who had breast augmentation with polyacrylamide hydrogel injection. The distribution and late changes of the injected material was observed.</p><p><b>METHODS</b>The physical signs and symptoms of the 16 patients were classified. Ultrasound and infrared examinations or MRI were used in some cases.</p><p><b>RESULTS</b>Two patients had operations for extraction. The injection material was distributed in the muscles diffusely, or existed in the breast and subcutaneous tissue as many masses.</p><p><b>CONCLUSION</b>The reliability of this injection method for breast augmentation is in doubt.</p>

Objective To introduce three new methods for measuring breast volume. Methods The breast volume was measured and the 3D image yielded with a special software or calculated with two mathematical formulas, according to its base, horizontal and saggital sections. Results The average deviations of these protocols were less than 10 % of the actual sizes in our investigation. Conclusion The computer aided measurement for the volume of the breast is an accurate and reliable method and can be used in the designs for augmentation and reduction of mammaplasty.
ABSTRACT
Objective To investigate the relationship between the change of blood flow in exceedingly expanded skin and the viability of the flaps. Methods In 21 expansions of 10 patients, the skin blood flow and its amplitude were measured by laser Doppler in different stages. The results were compared with the final outcomes of patients. Results The volume of blood flow and its amplitude of normal skin were very low and stable, but after expanded, the volume of blood flow and the amplitude grew up, which were significantly higher than that of normal skin (P
