Plan: The study will be conducted as a single-centre, randomized, triple-blind placebo-controlled trial to be performed at the QEII Health Sciences Centre, Halifax, Nova Scotia. Subjects will be chosen as healthy female patients already presenting to the operating room for elective breast reduction surgery. These patients will be enrolled and booked for surgery as they present to clinic and will not be expedited in receiving their elective surgery if enrolled in the study. Each subject will serve as her own control. The hypothesis will be tested by performing lipoaspiration of the thigh/hip region of healthy patients after the addition of tumescent solution with or without NAC. Approximately 10 millilitres of the fat graft will be injected into each pre-tibial area depending on the randomization allocation, as described by Kolle et al. (1) The volume of fat graft will be measured at 0, 1 and 3 months using computed tomographic (CT) scans according to institutional standards. The CT images will be exported into Materialise Interactive Medical Image Control System (MIMICS) and volumetric three-dimensional reconstructions will be made to measure the size and volume of the grafts at each of the time points. The grafts will then be explanted at 3 months and weighed. The histologic appearance, graded on the amount of inflammation, cysts/vacuoles, integrity and vascularity with CD31 staining will be assessed. The results will be compared using two-tailed t-tests. Statistical significance will be set at p<0.05.
