This will be a single-blinded study where participants are blinded to the suture type but the surgeon will draw a random, unmarked envelope containing the designated suture type at the start of the surgery. 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. Three (3) main procedure groups will be transgender gender-affirming top surgery, cisgender female breast reduction or augmentation (including healthy and cancer patients; subgroup analysis will be performed), and cisgender male gynecomastia surgery. The goal is n=180 patients, n=60 per type of suture with n=20 per type of procedure (totaling n=60 per type of procedure). NAC width for each breast will be measured intraoperatively, at 2 weeks postop, 6 weeks postop, 3 months postop, and 6 months postop. These measurements will be deidentified and logged into a secure data entry form. Information on whether a secondary outcome occurred (ie. infection, dehiscence, revision and nipple necrosis) will be logged in this form as well. Because the sutures will be kept non-visible under dressings until the clinical followup appointment 2 weeks postop, the patient will remain blinded as to the type of suture used on their NAC(s). At this point, absorbable sutures will have been largely dissolved and non-absorbable sutures will be removed.
