Also, the LARS graft should eventually be superseded by the autologous graft (there is a school of thought that synthetic grafts often eventually fail, but by the time this happens with a hybrid LARS, the autologous graft should have well & truly incorporated, hence, it should be a relatively normal size to do its job properly.
Using less donor tissue is really only of benefit if the surgeon is concerned that the donor tissue will be weakened & susceptible to failure, but this is relatively uncommon.
