Surgical glue or sutures for a tummy tuck?

Hello and thank you for your question.   In my practice, I use many layers of sutures for a tight closure.  It is important to close the deep layers with sutures.  The
best advice you can receive is from an in-person consultation.  If you are an appropriate candidate for a tummy tuck, this can be done through a
low and short incision, all completely below the bikini line.  The belly button can be designed to look
natural and have no scars on the exterior.  
Your muscles can also be plicated resulting in a flat abdomen.  Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.  The most important
aspect is to find a surgeon you are comfortable with. I recommend that you seek
consultation with a qualified board-certified plastic surgeon who can evaluate
you in person.
Best wishes and good luck.

Optimally patients are permitted to shower on post op day 1. This enables good hygiene at the operative site. 
Being able to do so may be predicated on a surgeons ability to perform the drainless tummy tuck procedure as drains can sometimes be difficult in the shower. 
Wounds are closed with layers of sutures and then either mastisol with steri strips or Dermabond at the skin topical level. 
Drainless tummy tuck allows for earlier mobilization and return to routine hygiene. 
Talk with your surgeon about post op care. 

The deep layers of closure need to be done with sutures, however for the final layer of skin closure I've had good results with both sutures and tissue adhesive so it's really what your surgeon feels will work best for you. Hope that helps!
