Many board-certified plastic surgeons believe that accessibility of hands-on training in ultrasound-guided gluteal fat grafting (US-GGFG) is insufficient. Cadaver models utilized to practice ultrasound-guided fat grafting have proven to be expensive and difficult to procure.
The authors present a novel, clinically relevant buttock model, and compare this model with the costs and logistics of the cadaver model with the aim of providing affordable hands-on training for US-GGFG.
A clinically relevant buttock model, the Miami butt model (MBM) was created by attaching a hemiabdominoplasty specimen to a portion of pork belly with its skin attached.The costs and logistics related to 2 separate ultrasound-guided Brazilian butt lift (BBL) workshops, 1 with cadaver specimens and the other with the MBM, were compared.
The specimen costs for a workshop with 20 participants (10 stations with 1 cadaver specimen for 2 participants) were $4580 per station. After adding the cost of delivery and disposal for the cadaver specimens ($7770), the total price for a 10-cadaver-specimen workshop amounted to $53,570. The MBM was found to be anatomically relevant and provided a close facsimile of US-GGFG experience in humans, at a cost of $47 per specimen. The MBM cost of specimens for a 20-participant workshop totaled $940, compared to a cadaver-based workshop with specimen costs of $53,570.
Compared to the cadaver model, the MBM is significantly less expensive and allows the participant to perform US-GGFG on a close facsimile of human gluteal anatomy, improving the accessibility of US-GGFG training.
许多获得委员会认证的整形外科医生认为,超声引导下臀肌脂肪移植(US-GGFG)的实践培训机会不足。用于练习超声引导下脂肪移植的尸体模型已被证明成本高昂且难以获取。
作者提出一种新型的、与临床相关的臀部模型,并将该模型与尸体模型的成本和后勤保障进行比较,旨在为US-GGFG提供经济实惠的实践培训。
通过将半腹壁成形术标本附着于带皮肤的猪肚部分,创建了一种与临床相关的臀部模型——迈阿密臀部模型(MBM)。比较了两个独立的超声引导下巴西臀部提升(BBL)工作坊的成本和后勤保障情况,一个工作坊使用尸体标本,另一个使用MBM。
一个有20名参与者的工作坊(10个站点,每个站点1个尸体标本供2名参与者使用)的标本成本为每个站点4580美元。加上尸体标本的运输和处理成本(7770美元)后,一个有10个尸体标本的工作坊总价达到53570美元。发现MBM在解剖学上具有相关性,并且能提供与人类US-GGFG体验非常相似的模拟,每个标本成本为47美元。一个有20名参与者的工作坊使用MBM的标本成本总计940美元,而基于尸体的工作坊标本成本为53570美元。
与尸体模型相比,MBM成本显著更低,并且能让参与者在与人类臀肌解剖结构非常相似的模型上进行US-GGFG操作,提高了US-GGFG培训的可及性。
