Abstract
BACKGROUND: Aesthetic surgery training renders to be challenging to acquire sufficient hands-on experience during residency. To resolve this problem, the "Munich Model" was established in our clinic: Senior residents perform aesthetic surgeries, supervised by an experienced plastic surgeon while patients benefit from reduced surgery costs. With this model, we hypothesize no significant differences in the postoperative outcome between procedures performed by residents and plastic surgeons. METHODS: Between August 2012 and December 2017, 481 aesthetic surgeries were included in this retrospective single-center study, of which 283 were performed by residents and 198 by plastic surgeons. Procedures included mastopexy, abdominoplasty, extremity lift, breast reduction, breast augmentation, facial surgery, aesthetic liposuction and lipedema liposuction. Postoperative outcomes were compared regarding surgery time, time of drain removal, inpatient length of stay, duration of wound healing, perioperative blood loss and occurrence of major (surgical revision needed) and minor complications (no surgery needed). RESULTS: We found no significant differences in aesthetic surgical procedures between residents and board-certified plastic surgeons in the outcome measures of surgery duration, time of drain removal, inpatient length of stay, perioperative blood loss and complication rate, including major and minor complications. Only the inpatient stay was prolonged in aesthetic liposuctions performed by residents. CONCLUSION: This study demonstrates comparatively that supervised aesthetic surgeries at a university hospital utilizing the "Munich Model" widely meet the specialist surgeons' standards.
