Scarring Concern from Open Rhinoplasty with Dissolvable Stitches

The open rhinoplasty columellar incision can heal well with both dissolvable sutures or non-dissolvable sutures that are then removed around 1 weeks after surgery. Some surgeons use a combination of both types in their closure.

How the incision heals has more to do with surgical technique and post-operative care than the actual type of suture used. Look at photos (you'll need to see the base view) of your potential surgeon's after results to see how well their incisions heal. If you follow the prescribed incision line care the dissolvable sutures should come out on their own after 10-14 days or so. Your surgeon can remove them at any time after 1 week postoperative (just like removing non-dissolvable sutures) if needed though.

The incision between the nostrils heals extremely well as seen on the link below.  I typically use non-dissolving sutures since they can be removed when I want the to vs. leaving them to dissolve on their own.

Incisions in the columella of the nose tend to heal well regardless of the type of suture used. If the skin edges are well aligned and allowed to heal for an appropriate time the results are usually excellent. If the dissolvable sutures have not fallen out by two weeks the surgeon will usually remove them.
