How Long Should Surgical Glue from Rhinoplasty Last?

Hi dolphin,
I am not aware of a "lip incision" approach to rhinoplasty. You should contact your son's rhinoplasty surgeon to get the answer to your question.
If you are referring to the columella of the nose (the center divider under the nose between the nostrils), during an external or open approach rhinoplasty an incision is made there. That area is normally sutured and then the stitches are removed between 5 to 7 days after surgery.
I personally don't usually "take any lip" from my patients, although I do encourage open communication.
I hope that both your son and you are very pleased with his new nose. Good luck and be well.

You should call the doctor who did the surgery to answer the question. He knows what type of "glue" he used and when it should fall off.

Hi @DolPhin - Skin Glue typically takes 2 weeks to dissolve or flake off.  Sometimes it can take a little while longer but that's nothing to worry about! It might actually be better. Sometimes, applying a little vaseline if it has been 2 weeks can help dissolve the glue. I would recommend following up with the plastic surgeon that did your surgery and just let them know if they want you to do anything or not. Best of luck!
