Study Objective:
To describe a new technique of neovaginoplasty after a female sex reassignment surgery using a tilapia skin as a graft.
Design:
Stepwise demonstration of a new technique with narrated video of a single case report. The patient provided oral and written informed consent. Moreover, this video report is part of a multicenter, Investigational Review Board-approved study.
Setting:
Women's university hospital in Campinas, Brazil.
Interventions:
Neovaginoplasty technique using tilapia skin with the following key strategies: (1) corpus cavernosum removal, (2) vagina tunnel creation, (3) mold coating with tilapia skin, (4) mold fixation, and (5) postoperative care. The patient remained with the mold coated with tilapia skin for 5 days; after this time, the mold was removed, and the tissue graft was adhered and incorporated in the new vaginal canal. After 2 months, the tissue resembled a vaginal mucosa, and the vaginal length was 8 cm. The patient has not had intercourse yet.
Conclusion:
We introduce an alternative for low-morbidity neovaginoplasty based on the experience of plastic surgery in burned grafts. The procedure described offers an alternative option to develop an anatomic neovagina with tissue similar to mucosa tissue by a simple, low-morbidity minimally invasive procedure.
