I had tissue improvement treatment with stem cells before revision surgery due to nasal contracture. The hospital where I was going to have nasal surgery said they didn't offer stem cell therapy, so I searched for a hospital that specializes in stem cell treatment and came through a referral. My nasal condition wasn't good and contracture developed, but after receiving tissue treatment with stem cells, my immune system improved as well, and fortunately, even several months after the revision surgery, everything is fine.
