There's a reason the humble nose job is still one of the most popular procedures out there: It has a way of subtly enhancing the entire face. San Diego rhinoplasty specialist Dr. Richard Chaffoo says changing the shape of the nose is one of the best ways to bring facial proportions in balance.But there's also more to it than that. Here are 5 of our favorite facts.1. It can last forever. The nose is unique from other parts of the body because it ages differently. While your butt may sag and your lips thin out, the nose endures, more or less retaining its shape for the entirety of your days. This means that, unlike those of facelift surgery, breast lift, or other age-defying procedures, the results of a rhinoplasty can actually last for the rest of your life. Of course, rhinoplasty doesn't make your nose invincible. Its appearance can still be altered by external factors, such as an injury.2. It's not just for looks. Seriously. The next time someone says they've undergone rhinoplasty in order to fix a "deviated septum" or some other vague respiratory ailment, believe them. "Functional rhinoplasty" is a variation on the surgery that focuses specifically on improving breasthing, rather than the form of the nose. This is often indicated for chronic congestion, sinus problems, and even cases of severe snoring. This type of rhinoplasty can even be performed without affecting the appearance of your nose, though many people opt to do both at once.

3. It's not just for adults.

Rhinoplasty is one of the few elective cosmetic procedures that's suitable for teens as well as adults. This is because, unlike the breasts, face, or other parts of the body, the nose stays relatively the same once it's fully developed, which happens by around age 15 or so. It's not uncommon for high school students to have nose surgery over summer break, once school lets out.

4. Healing is slow and steady.

You may have heard that the healing process after rhinoplasty can take up to a year. Although that's not technically an exaggeration, it doesn't tell the whole story, either. The nose is an incredibly intricate structure, and many plastic surgeons consider rhinoplasty one of the most technically challenging aesthetic procedures. While surgeons typically remove dressings and sutures after about a week, it can take up to a year for all the structures of the nose to completely settle into their final positions. During this time, patients may not see a significant day-to-day change, but they will likely notice a big difference when comparing before-and-after photos.

5. You don't always have to break the nose.

Yes, purposely breaking some of the bones in the nose in order to reset them into new positions is sometimes a required part of rhinoplasty, depending on what you'd like to have done. But it's not always necessary. For example, reducing the size of the nasal tip, a common patient request, doesn't typically require a break. Neither does removing a hump or bump on the nasal bridge. During a consultation, your doctor should be able to tell you whether or not your nose will require a break.
