Abstract

Background and Objectives The transverse musculocutaneous gracilis (TMG) flap has gained popularity for breast reconstruction. However, the literature regarding its donor site morbidity is heterogeneous. This systematic review sought to clarify the evidence on donor site morbidity. Methods A systematic literature search was conducted. We included all articles reporting on donor-site morbidity of the TMG flap for breast reconstruction. The results were analyzed in R and its extension meta. A generalized linear mixed model was used to combine proportions and their 95% confidence intervals (CIs) in a random-effects meta-analysis. Results Nineteen articles provided an overall sample of 843 TMG flaps. The total flap loss was low at 2% (95% CI, 1%-3%). All patients were normal weight (pooled body mass index 22.75, 95% CI, 21.88-23.63). The incidence of wound dehiscence (8%, 95% CI, 4%-16%), seroma (4%, 95% CI, 2%-7%), hematoma (2%, 95% CI, 1%-4%) and infection (0%-5%) on the TMG donor site was low. Functional impairments included sensory disturbance (0%-74%), motoric deficits (0%-50%), and changes in the genital region (0%-24%), all of which were modest. Conclusions This review confirms the safety and low donor site morbidity of the TMG flap in normal-weight patients, which is comparable to that of other popular free flaps in breast reconstruction.
