Microfocused ultrasound is a unique technology to treat skin laxity of the brow, lower face, and the rhytides of the décolletage. Over the past several years, the efficacy and safety of this device has been well documented and its adoption widespread. By delivering focused acoustic energy, which is converted to heat, this device creates predictable and reproducible microcoagulative zones that initiate a concentrated inflammatory wound response. By targeting the deep reticular dermis and superficial muscle and fascial planes, such as the superficial musculoaponeurotic system, platysma, and pectoralis muscle fascia, this nonablative technology increases neocollagenesis and neoelastogenesis in a novel fashion, while avoiding many of the complications related to epidermal heating observed in several other nonablative devices. Although the results are not equivalent to those of a rhytidectomy, microfocused ultrasound provides an excellent noninvasive means to achieve a regenerative effect on the face, neck, and décolletage when performed in the appropriate patient population.
微聚焦超声是一种用于治疗眉部、下脸部皮肤松弛以及颈部皱纹的独特技术。在过去几年中，该设备的有效性和安全性已得到充分记录，并且其应用广泛。通过传递聚焦声能并将其转化为热量，该设备可产生可预测且可重复的微凝固区，引发集中的炎症性伤口反应。通过靶向深部网状真皮以及浅表肌肉和筋膜平面，如浅表肌肉腱膜系统、颈阔肌和胸肌筋膜，这种非剥脱性技术以一种新颖的方式增加了新胶原生成和新弹性生成，同时避免了在其他几种非剥脱性设备中观察到的许多与表皮加热相关的并发症。尽管其效果与除皱手术的效果并不等同，但在合适的患者群体中进行微聚焦超声治疗时，它为面部、颈部和颈部皮肤提供了一种出色的非侵入性手段，以实现再生效果。
