A Clinically Relevant Model for Hands-on Training in Ultrasound-Guided Gluteal Fat Grafting: The Miami Butt Model.

Abstract

Background: Many board-certified plastic surgeons believe that accessibility of hands-on training in Ultrasound-Guided Gluteal Fat Grafting, (US-GGFG) is insufficient. Cadaver models used to practice ultrasound-guided fat grafting, have proven to be expensive and difficult to procure.

Objectives: 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.

Methods: A clinically relevant buttock model, Miami Butt Model, (MBM) was created by attaching a hemi- abdominoplasty specimen to a portion of pork belly with its skin attached.The costs and logistics related to two separate ultrasound-guided BBL workshops, one using cadaver specimens and the other using the MBM were compared.

Results: The specimen costs for a workshop with 20 participants (10 stations with one cadaver specimen for 2 participants), were $4,580 per station. After adding the cost of delivery and disposal for the cadaver specimens ($7,770), the total price for a 10-cadaver specimen workshop would amount to $53,570. The MBM was found to be anatomically relevant and provided a close facsimile of US-GGFG experience in human subjects, at a cost of $47 per specimen. The MBM cost of specimens for a 20-participant workshop would total $940 compared to a cadaver-based workshop with specimen costs of $53,570.

Conclusions: 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.
