How often cortisone injections are given varies based on the reason for the injection. This is determined on a case-by-case basis by the health care practitioner. If a single cortisone injection is curative, then further injections are unnecessary. Sometimes, a series of injections might be necessary; for example, cortisone injections for a trigger finger may be given every three weeks, to a maximum of three times in one affected finger. In other instances, such as knee osteoarthritis, a second cortisone injection may be given approximately three months after the first injection, but the injections are not generally continued on a regular basis.
At times an inordinate amount of scar and/or edema (swelling) can build up in the nasal dorsum or tip. Such as after a resection of a dorsal hump deformity giving the appearance that the deformity has been inadequately resected. Steroids after rhinoplasty are used as a means to reduce the amount of scar tissue and/or swelling that has formed. While being helpful, it does have potential side effects. It may cause atrophy of the tissues resulting in a depression, or cause hypopigmentation (loss of color) or even thinning of the overlying skin. Make sure you continue to follow up closely with your plastic surgeon as they will be best able to guide you through your post operative recovery. Best wishes.
