  Background:We studied the safety and the efficacy of a 1064nm Nd:YAG laser with minimal suction for face contouring; the reduction of small unwanted fat areas and the enhancement of skin tightening? Method:From October 2010 to December 2010, Twenty subjects with the problem of face contour were enrolled.Treatment areas included the medial cheek, jowl area, and submentum.The treatment was performed using a 1064nm Nd:YAG laser.After tumescent anesthesia, a 2-mm diameter cannula was inserted via a puncture into subcutaneous layer.Unwanted subcutaneous fat was removed by aspiration.Then a 1-mm diameter microcannula housing a 300micrometer optical fiber was inserted into the subcutaneous fat.The cannula was moved back and forth in a predetermined manner to get a homogeneous distribution of an energy at the treated area.The amount of total cumulative energy was 600J~3000J that was determined by the extent of the treated area, the reduction of the volume and the surface temperature.Patient satisfaction was evaluated and side effects were recorded.The Clinical photos were used for the comparison of pre and post-procedure state.Results:Contour correction and skin retraction were observed almost obviously in most patients.There was no significant side effect such as scarring, infection, burns, hypopigmentation.The most common side effects were mild bruising and swelling resolving within a week.Patient satisfaction was evaluated by Likert type scale, ranging 1~5.The mean of the scale was 4.2, representing of high satisfaction about the procedure.Conclusion:Laser lipolysis using the 1064nm Nd:YAG laser combined with minimal aspiration appears to be first choice of the treatment for face contouring that delivers good, reproducible results safely and effectively.The advantages include excellent patient tolerance, quick recovery time, as well as the benefit of dermal tightening.Reference : 1.Melanie D.et al: Laser lipolysis: Current practice.Semin Cutan Med Surg 2009; 28:212-219.2.Karen H.Kim et al: Laser lipolysis using a novel 1,064nm Nd:YAG Laser.Dermatol Surg 2006; 32:241-248.3.Peter McKinney et al: Liposuction and the treatment of nasolabial folds.Aesth Plast Surg 1989; 13: 167-171.4.Gordon et al: Quantification of Human Abdominal Tissue Tightening and Contraction After Component Treatments With 1064nm/1320nm Laser Assisted Lipolysis:Clinical implications.Aesth Surg J 2010; 30(2): 239-248.
