My understanding is that conventional approach is to sever the entire ligament, and this explains why historically Surgeons have sometimes used "spacers" (whether using silicone, other tissue, etc.) in order to prevent ligament from
healing and reattaching. However, I've always found this confusing, and wonder if I've misunderstood the purpose of spacers since ligaments don't readily reattach themselves when they've been completely severed (according to a number of sources I reviewed before submitting this post strongly suggests that a Surgeon would need to reattach them).
Then again perhaps the ligaments found supporting the penis may behave differently, I can't say for sure. Perhaps
@PhalloplasticSurgeon_DrLiu
could chime in).
What you'll come to learn is that Ligamentolysis (the surgery of severing your ligaments in order to let more of your
inner penis hang forward has many different approaches depending on the Doctor: some sever completely, others partially (in this case, Dr. Liu), some use spacers and some don't believe in them at all, some use sharp surgical tools and others lasers, and post-op stretching protocols vary Doctor-to-Doctor. Basically,
Ligamentolysis is NOT a standardized surgical procedure, so it is best to see a Surgeon with experience. Dr. Liu certainly a trustworthy choice.
I guess to answer your question, go with what the Doctor recommends. Worst case scenario, you can go back in to get the entire ligament severed if your post-op protocol isn't as responsive as you'd hoped. Those are my 2cents.
