Injection rhinoplasty is when a filler such as Radiesse is used to fill in a portion of the nose to alleviate the appearance of a bump. This is typically a procedure used to correct small defects, and should be done with extreme caution by a surgeon highly skilled in the arts of rhinoplasty and injectables. Nasal skin is extremely thin so any abnormality can become very visible, and detract from the results you were hoping for.
Injection rhinoplasty is very different from a rhinoplasty surgery in which the structure of the nose is modified to bring balance & harmony to the face. And while a traditional procedure may take a bit longer to heal and be a bit more of a recovery, it’s also more likely to offer a result you will be pleased with.
