Will my surgery process fail if my stitches come out of my nose as opposed to dissolving?

Thanks for your question. I'd bet that your sutures actually DID dissolve like they were supposed to, so that's why they came out. The only parts that dissolve are the parts beneath the surface. Anything on the surface remains as is and won't dissolve. It tends to attract big clumps of debris, which is what you saw today. No worries.
