Can it be stitch back to normal? I accidentally pull a stitch off now it's open. Close Rhinoplasty.

I believe I accidentally pulled a stitch while healing from my close rhinoplasty in march. Now it have a little opening that haven't been able to close since it expose the implant of the nose. It has been a few months, Can this be fix? I think this is one of the reason why my nose haven't been healing properly. It been 8 months post op. And it was done over sea so I can't meet the surgeon there. What to do now? And how much would it cost to just close it again?
