Tips to Prevent Further Swelling After Rhinoplasty?

Taping the bridge of the nose and the supratip area (area above the tip) can significantly reduce postoperative edema (swelling). Gentle pressure from the tape does two things. First, it can help 'press' out some of the swelling that results from trapped fluid in the tissues.
Secondly, and perhaps more importantly, pressure on the tissues causes the collagen fibers in scar tissue to become more organized, which reduces the volume of the swollen area.The most effective for taping is in the first six months after surgery.
You should schedule an appointment with you surgeon to discuss whether or not this is right for you and to get formal instructions on the right way to take it.

The hardest part of the rhinoplasty is waiting for months to see your final result! the tip area, especially in open rhinoplasty surgery, takes the longest for the swelling to completely resolve. Some surgeons like to use taping to help put compression on the area, though it depends on the surgeon. Sleeping on two pillows to raise your head and help with swelling also helps. but ultimately the most important factor is time. There are no major shortcuts.

The nasal tip takes the longest time to recover from the swelling after rhinoplasty surgery-especially if the procedure was performed open (an incision made on the columellar skin).  Because this incision interrupts the lymphatic drainage of the tip, it takes longer for the tip swelling to resolve. Compression of the soft tissue may help, such as compression exercises or taping; however, I would NOT do this without first asking your surgeon. Sleeping with your head on 2 pillows may also help some. If your surgeon thinks it is necessary, he or she may want to inject a small amount of steroid into the tip to decrease swelling. but, for the most part, just being patient is the best course of action.
