Can you advise on sudden bump on columellar incision 6 months post rhinoplasty? (Photos)

Hello! Thanks for the question and photos. It could be a suture granuloma. This is when suture remains and the body tries to get rid of it. The remedy is to explore the area for suture and remove it. If any pus is present, that can be removed, cultured, and the area thoroughly cleaned. Sometimes, a topical and oral antibiotic may be merited. I would let your surgeon know and see what needs to be done. Good luck and hope you heal quickly!

Hello 6 month early period but scar will heal don't worry it depens on your healing process and your anatomy

That can be a stich (deep, not removed resobrable stich??) or a small infected pustula around insicion. Topical antibiotic ointment or incision, drainage (per your surgeon) are options to be considered. Good luck.
