The safety and efficacy of the 980-nm diode laser for laser lipolysis were evaluated in different body areas.
From June 2005 to June 2007, 334 subjects underwent laser lipolysis. The treatment was performed using a 980-nm diode laser (OSYRIS, Hellemmes, France). After tumescent anesthesia, a 1-mm-diameter microcannula housing a 600-mum 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 energy at the treated area. Laser settings (power and cumulative energy) were selected in relation to individual body areas: 6 W (chin, arm, knee), 10 W (abdomen, back), and 15 W (thigh, hips, buttock). Patient satisfaction was evaluated and side effects were recorded. The laser energy counter incrementally counted the energy used; then the cumulative energy used for each treatment was recorded. Ultrasound imaging was used to control tumescent anesthesia infiltration, cannula position prior to laser emission,and postoperative fat liquefaction.
Five hundred thirty-four (534) laser lipolysis procedures were performed on 334 patients. Different areas were treated: hips (197), inner thighs (86), abdomen (86), knees (61), flanks (57), buttocks (28), chin (22), arms (18), back (4). Mean cumulative energy was area-dependent, ranging from a minimum of 2200 J (knee) to a maximum of 51,000 J (abdomen). Contour correction and skin retraction were observed almost immediately in most patients. There was no scarring, infection, burns, hypopigmentation, bruising, swelling, or edema. Ecchymoses were observed in almost all patients but resolved in under 1 week for 322 patients. Patient satisfaction was very high. Because laser lipolysis is an outpatient procedure, patients were able to resume normal daily activities after 24 h. Ultrasound imaging confirmed that the thermal effect generated by the laser results in melting and rupture of the collagenous and subdermal bands.
This clinical study demonstrates that the removal of small volumes of fat with concurrent subdermal tissue contraction can be performed safely and effectively using a 980-nm diode laser. Additional benefits include excellent patient tolerance and quick recovery time. This study also confirms that enough accumulated energy must be delivered to achieve sufficient lipolysis throughout different fat layers.
评估了 980 纳米二极管激光用于激光溶脂在不同身体部位的安全性和有效性。
2005 年 6 月至 2007 年 6 月，334 名受试者接受了激光溶脂治疗。使用 980 纳米二极管激光（OSYRIS，法国埃勒梅斯）进行治疗。在肿胀麻醉后，将一根容纳 600 微米光纤的直径 1 毫米的微插管插入皮下脂肪。插管以预定方式来回移动，以使治疗区域能量均匀分布。根据个体身体部位选择激光设置（功率和累积能量）：6 瓦（下巴、手臂、膝盖）、10 瓦（腹部、背部）和 15 瓦（大腿、臀部、臀部）。评估患者满意度并记录副作用。激光能量计数器逐步计算使用的能量；然后记录每次治疗使用的累积能量。使用超声成像来控制肿胀麻醉的浸润、激光发射前插管的位置以及术后脂肪液化。
对 334 名患者进行了 534 次激光溶脂手术。治疗了不同部位：臀部（197 次）、大腿内侧（86 次）、腹部（86 次）、膝盖（61 次）、侧腹（57 次）、臀部（28 次）、下巴（22 次）、手臂（18 次）、背部（4 次）。平均累积能量因部位而异，范围从最低的 2200 焦耳（膝盖）到最高的 51000 焦耳（腹部）。大多数患者几乎立即观察到轮廓矫正和皮肤回缩。没有瘢痕形成、感染、烧伤、色素减退、瘀伤、肿胀或水肿。几乎所有患者都观察到瘀斑，但 322 名患者在 1 周内消退。患者满意度非常高。由于激光溶脂是门诊手术，患者在 24 小时后能够恢复正常日常活动。超声成像证实激光产生的热效应导致胶原带和皮下带的融化和破裂。
这项临床研究表明，使用 980 纳米二极管激光可以安全有效地去除少量脂肪并同时使皮下组织收缩。其他益处包括患者耐受性良好和恢复时间快。这项研究还证实，必须传递足够的累积能量以在不同脂肪层实现充分的溶脂。
