Geometrical Advanced Surgical Marking Technique in Gender-affirming Mastectomy

Background: Nowadays in gender reassignment surgery, the application of marking techniques acquires a crucial relevance. In this context, using a geometric hybrid technique for preoperative marking in mastectomy has proven to be a fundamental tool. Material and Methods: The main purpose of this article is to discuss a case series of 6 cases, of an advancement of Breast Flaps and use it as a length in the average chest in Mexican patients with III degree of Gynecomastia and with Ptosis by Regnault II degree. The Geometrical flaps are 2 rectangular triangles, with 90-degree flaps of a VY advancement, and a Graft of 32 or 34 millimeters Nipple-Areola. Discussion: Surgical marking practices in sex reassignment mastectomy are examined, taking into account the reports of Berry et al. as well as the studies of Namba et al. and Knox et al. In addition, the comparative study by Rifkin et al. adds a contemporary perspective, comparing periareolar and double incision patterns. The synthesis of these findings offers a comprehensive exploration of surgical marking practices delving into hybrid geometric techniques, from which surgeons, researchers, and transgender healthcare professionals will benefit. Conclusion: This technique was reproducible in all patients who underwent the surgical procedure after geometric hybrid marking for mastectomy where the NAC graft (nipple-areola complex) was reproduced without complications.
