Gluteal hypoplasia and ptosis reduction are common concerns among patients seeking optimal body contouring in Peru and other countries. Although silicone implants are a traditional solution, they are not suitable for all patients. Fat grafting has emerged as an alternative, with various techniques aimed at enhancing fat graft viability and patient safety.
We conducted a study to evaluate the effectiveness and safety of ultrasound-guided helium pneumodissection for gluteal-hip contouring. Between January 2021 and December 2022, 220 patients with varying degrees of gluteal hypoplasia were treated using ultrasound-assisted helium pneumodissection.
The amount of fat grafted ranged from 200 to 1500 mL per buttock, with most patients receiving 701-800 mL. The integration of color Doppler ultrasound allowed for precise visualization throughout the procedure and safe placement of fat grafts. Helium pneumodissection facilitated efficient fat graft injection with reduced resistance at the recipient site. Mild complications included temporary hyperthermia in 4.5% of patients and one instance of retraction in the lower quadrant of the right buttock.
Ultrasound-guided helium pneumodissection for gluteal-hip contouring demonstrates significant advantages in patient safety, fat graft viability, and overall satisfaction. This advanced technique allows for efficient fat injection with reduced resistance in the subcutaneous plane, minimizing the risk of deep plane injections into the muscle. Although occasional mild complications were observed, they were manageable and did not compromise the overall safety of the technique.
在秘鲁和其他国家，寻求最佳身体塑形的患者普遍关注臀肌发育不全和下垂改善问题。尽管硅胶植入物是一种传统解决方案，但并不适用于所有患者。脂肪移植已成为一种替代方法，有多种技术旨在提高脂肪移植的存活率和患者安全性。
我们开展了一项研究，以评估超声引导下氦气气动解剖用于臀部-髋部塑形的有效性和安全性。2021年1月至2022年12月期间，对220例不同程度臀肌发育不全的患者采用超声辅助氦气气动解剖进行治疗。
每侧臀部移植的脂肪量为200至1500毫升，大多数患者接受701 - 800毫升。彩色多普勒超声的应用使得在整个手术过程中能够精确可视化，并安全地放置脂肪移植体。氦气气动解剖有助于高效地进行脂肪移植注射，减少受体部位的阻力。轻度并发症包括4.5%的患者出现暂时性体温过高，以及右臀部下象限出现一例回缩情况。
超声引导下氦气气动解剖用于臀部-髋部塑形在患者安全性、脂肪移植存活率和总体满意度方面显示出显著优势。这种先进技术能够在皮下平面高效地进行脂肪注射，减少阻力，将深部平面注射到肌肉中的风险降至最低。尽管观察到偶尔出现轻度并发症，但这些并发症是可控的，并未影响该技术的总体安全性。
