Skin Graft Vaginoplasty

Unlike the traditional Penile Inversion Technique, which rolls penile skin inward to create the vaginal canal (often resulting in insufficient depth or poor aesthetic outcome in patients with small genitalia or prior circumcision), Dr. Chettasak’s NPI technique preserves the penile skin for crafting delicate and natural-looking external genital structures, such as the labia minora and vaginal introitus.

Skin Graft Vaginoplasty in this approach uses only scrotal skin (Total Scrotal Skin Graft), which is trimmed and thinned to an ideal thickness (approximately 0.3–0.45 mm) to form the entire neovaginal lining.

If the scrotal skin is insufficient after designing the outer labia (labia majora), Dr. Chettasak may harvest additional skin from the groin area. This site is chosen over more distant areas such as the lower abdomen or inner thighs to avoid large or visible scars.
