It's been 5 years, and since 3 months after the surgery I've only lived thinking about revision surgery.
It seems to have been a scarless surgery where they lifted and cut flesh from inside the nose, which made my short columella curl upward even more.
They never openly explained the surgical process, so at every clinic I visited for revision consultations, I struggled to infer what method had been used.
The doctor's attitude before and after surgery was completely different (and that matters a lot). The staff are just okay.
