Hi Beba246. Infection in rhinoplasty is very uncommon but not impossible. There are definitely things that can be done during and after the surgery to minimize the risk of infection. I use meticulous sterile technique during surgery to reduce the risk of infection. Patients are also given antibiotics during the surgery, as well as for a few days afterwards. In addition, I instruct patients very carefully on how to take care of the nose afterwards to reduce risk of infection. So, although the risk of infection in rhinoplasty is low, it can be reduced with proper technique. In response to your first question, the strength of the nose after rhinoplasty depends on surgeon's technique. Historically, the trend was towards excisional rhinoplasty to make the nose smaller, so a significant amount of the nasal cartilage was removed. This excisional rhinoplasty approach can weaken the nose, if certain measures aren't taken during surgery to restore the strength. Current day philosophy focuses on structural rhinoplasty, where the strength and structure of the nose is maintained. Make sure to find a surgeon who is a specialist in rhinoplasty to ensure longlasting and predictable results .Good luck.
