Specialization and Background
Dr. Patricia Gutiérrez Ontalvilla is a specialist in Plastic, Aesthetic, and Reconstructive Surgery, with over two decades of clinical practice focused on vulvar pathology and female intimate surgery.
Her specific interest in vulvar lichen sclerosus arose from daily clinical practice—from continuous contact with women who arrived with years of symptoms without a correct diagnosis, or with treatments insufficient for the severity of their condition. That clinical reality was the driving force behind her research program.
Since 2004, she has directed Nixarian Institute SL in Valencia, a clinic specialized in vulvar pathology and the Liquenia® Treatment for vulvar lichen sclerosus.
Research Background
In 2017, she initiated a clinical research program on the use of stromal vascular fraction (SVF) and platelet-rich plasma (PRP) in the treatment of vulvar lichen sclerosus, in collaboration with La Fe University Hospital and the La Fe Health Research Institute (IIS La Fe) in Valencia.
The results of this work have been published in peer-reviewed international scientific journals:
Aesthetic Surgery Journal · 2025
