Reoperation after nose tip surgery only

Two years ago, after a nasal bone osteotomy, only the tip of my nose was extended to the septum.
 Maybe I raised the tip too high, but there is a lot of separation between the bridge of my nose and the tip of my nose. Even before the surgery, my nose bridge was high, so I decided to go for a consultation because almost no implants were recommended, so I guess I should have put at least 1mm of silicone instead. I regret it so much..
 The place where I had the surgery told me to pay more and get implants because
 my nose was like that in the first place. Rather, it was so bumpy that it looked like a curved nose. I was wondering whether I should get the nose surgery again at a different place or get an implant for just the bridge of my nose at the same hospital. I see... Are there many side effects from silicone? Is it okay to just redo the bridge of the nose after getting it done?
