Good question! And, in fact, one that I only found the correct answer from my original surgery team last week, when I received the bill for my June 2015 phalloplasty (yup, my health insurance company took *that* long to crunch the numbers and pay out their share).
The bill I received had an itemized list that counted every single thing done to me or item used on me during the surgery. While I thought I never had a vaginectomy, it turns out that’s not entirely true – the list said a *partial* vaginectomy was done.
This makes a lot more sense when you consider I have no outer or inner labia anymore, just a Y-shaped opening that goes right into the vagina.
