Localized deposits of fat (adiposis) located in the face, chin, neck, and arms usually are more compact and difficult to treat using conventional liposuction. It is necessary to find an effective approach for this type of localized adiposis. This study aimed to investigate the clinical application of laser lipolysis for the treatment of localized adiposis in Asian patients.
In this study, 35 patients with localized adiposis were treated by laser lipolysis. Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser energy was transferred through an optic fiber into the adipose tissue. The optimal energy and frequency of the laser were controlled precisely to melt and destroy the adipose tissue without damage to the skin and deeper tissues. The histologic study of treated adiposis tissues, the postoperation reaction, and the clinical results were observed and studied.
After laser lipolysis, the localized adipose tissues were liquefied effectively, and the compact fibrous tissues were broken down into a looser structure. Bleeding was noted to be less than with conventional liposuction due to the coagulation of capillary vessels and the thermal effect of the laser. Laser lipolysis caused less edema, petechiae, and other postoperative complications, producing rapid recovery and satisfactory results.
The Nd:YAG laser has a definite lipolysis effect on compact adipose tissue and is a more effective approach for the treatment of localized adiposis than conventional liposuction.
位于面部、下巴、颈部和手臂的局部脂肪堆积（脂肪症）通常更紧实，使用传统的抽脂术难以治疗。需要找到一种有效的方法来治疗这种类型的局部脂肪症。本研究旨在探讨激光脂肪分解术治疗亚洲患者局部脂肪症的临床应用。
本研究对 35 例局部脂肪症患者进行了激光脂肪分解术治疗。钕：钇铝石榴石（Nd：YAG）激光能量通过光纤传递到脂肪组织中。精确控制激光的最佳能量和频率，以融化和破坏脂肪组织，而不会损伤皮肤和更深层的组织。观察和研究了治疗后脂肪组织的组织学研究、术后反应和临床结果。
激光脂肪分解术后，局部脂肪组织有效液化，致密的纤维组织分解成更疏松的结构。由于激光的热效应和毛细血管的凝固作用，出血量比传统抽脂术少。激光脂肪分解术引起的水肿、瘀斑等术后并发症较少，恢复迅速，效果满意。
Nd：YAG 激光对致密脂肪组织有明确的脂肪分解作用，是治疗局部脂肪症比传统抽脂术更有效的方法。
