Brief Summary:
This will be a single-blinded study where the participants will be blinded to the type of suture. The patient population will be all patients undergoing breast surgery at the London Health Sciences Center (LHSC) - ie. University Hospital, Victoria Hospital and the Nazem Kadri Surgical Center - and St. Joseph's Hospital falling into one of 3 categories: transmasculine gender affirming top surgery, cisgender female elective or oncologic breast surgery (mastopexy, breast reduction, breast augmentation, or nipple-sparing mastectomy), and cisgender male gynecomastia correction.
Three sutures will be used: 4-0 Prolene, 4-0 Monocryl and 4-0 Stratafix. We will aim for n=180 participants, n=60 per type of suture, and n=60 per surgical category. This way, each suture type can be equally distributed among each surgical category. This means n=20 of each suture type will be used in n=20 of each surgery type. For example, n=20 top surgery patients will receive Prolene sutures, n=20 receive Monocryl, and n=20 receive Stratafix. All patients will be consented in the preop area on the day of their surgery by a member of the research team.
The primary outcomes will be NAC diameter or "width" intraoperatively immediately after closing compared to NAC width 2 weeks, 6 weeks, 3 months, and 6 months postoperatively. The horizontal and vertical widths will be measured at each time. Measurements are done with a ruler and recorded in centimeters. Prolene sutures will be removed at the 6-week postop visit as per current clinical practice. Absorbable will not be removed because they are absorbable.
Statistical regression will be used to determine whether a certain type(s) of suture is optimal for minimizing NAC widening after surgery. Subgroup analyses will also be conducted to determine any confounding factors from heterogeneity in patient factors within each group. Secondary outcomes will be rates of infection, tip loss, nipple necrosis and dehiscence, and whether certain types of sutures increase these adverse outcomes.
