Scarring Concern from Open Rhinoplasty with Dissolvable Stitches

The type of suture (stitches) used to close the columellar incision (incision between the nostrils) in open rhinoplasty has less of an impact on the visibility of the scar than the surgeon's skill and attention to detail.
While dissolvable sutures such as "chromic" and "fast-absorbing-gut" have been shown in studies to produce slightly more tissue inflammation than permanent sutures such as "nylon" or "prolene", excellent wound closure can be attained with dissolvable sutures.
Dissolvable sutures should remain in place for a minimum of 5-7 days to ensure that the incision has healed shut adequately. Most of these will dissolve sometime in the 7-14 day time period. Follow your doctor's recommendations on wound care to ensure that you get the best possible result.

I have a very specific protocol for my open rhinoplasty surgeries, in which I use prolene sutures for the skin and absorbable for the mucosa.  This yields excellent scars.

Generally dissolvable sutures work well, and dissolve within 7-10 days.  Any incision on the nose will take about a year to mature.  You can also consider fractional laser on the scars to reduce any scarring even further.  Follow up with your physician to ensure he/she is happy with the outcome.
