Fixation of the Compressive Dressing for Nipple-areola Complex Graft during Double Incision Chest Contouring Surgery for Assigned-female-at-birth Persons with Diagnosis of Gender Dysphoria: Sutures or Staples?

Abstract

Background:. When transplanting skin grafts, a compressive dressing is usually used to hold the skin graft in place. Dressing fixation can be achieved with either sutures or staples. The purpose of this study was to compare sutures and staples as a method of fixation for the compressive dressings of the nipple-areola complex (NAC) grafts, during double incision chest contouring surgery in assigned-female-at-birth persons with diagnosis of gender dysphoria. The two methods of fixation were compared according to pain at removal, time consumption, difficulty of removal, costs, and sustainability. Methods:. Forty patients were randomized to dressing fixation with either sutures or staples. Timing for dressing fixation during surgery and removing the dressing was measured. Pain during removal was measured using vNRS-11. Difficulty of removal was measured with VAS-100. Costs of materials were compared. Results:. All NAC grafts survived, and no complications such as infection or bleeding occurred. Staples were significantly more painful to remove when compared to sutures [mean vNRS-11 2.98 (SD ± 2.43) versus 1.25 (SD ± 0.92), P < 0.001]. Fixation with staples was faster than fixation with sutures (5.3 versus 94.6 s). No difference in removal time was found. Nurses found staples easier to remove. Sutures were slightly less costly (18 SEK) compared to staples (30 SEK). Finally, sutures produce less material waste. Conclusion:. Being that all other outcomes are similar or insignificant, the less-pain experienced at removal of sutures makes this the preferable method for fixation of the compressive dressing for NAC grafts during double incision chest contouring surgery.
