Our study showed that the SmartLipo appeared to be histologically effective for destruction of human fat tissue.

The internal jugular vein (IJV) is used as the optimal recipient for free-tissue transfer in reconstruction following modified radical neck dissection. Some reports documented rare cases of flap compromise following IJV thrombosis, but large sample studies are few. We present cases of emergent exploration and an analysis of factors to improve salvage rates of compromise due to IJV thrombosis. From a survey of 756 patients, four developed congestion due to IJV thrombosis and returned to the operating room. A restrospective analysis was made from the case records. This represents a rate of 0.5% for the entire series. Three flaps survived,and one failed. Detection of compromise ranged from 7-25 h postoperatively. All four IJVs recovered to provide adequate drainage after thrombectomy. While flap compromise following IJV thrombosis is rare, careful observation and early exploration are crucial for salvage, as in other microvascular venous crises.

Laser-assisted liposuction (LAL) or laser lipoplasty is widely used in Europe and Latin America, and has been introduced to Japan in 2004 and the United States in 2006. After the introduction of Smartlipo laser (DEKA, Italy), LAL has been rapidly advanced and in 2009 more than ten products of lasers for LAL are commercially available in the market. Recent models have advantages for faster and safer lipoplasty in their technologies, i.e., high power irradiation, skin temperature monitoring, acceleration sensor, and tough fibers. Selection of wavelength has been also developed. The author presents the basics and clinical experiences with these recent lasers for LAL.
