How Long Should I Wait for Kenalog Injections to Take Effect in the Nose?

Since steroid injections work by breaking the bonds between collagen (scar) bundles, the effect of localized steroid injection is to reduce scar tissue bulk beneath the surface of the skin. These injections need to be skillfully placed deeply enough to avoid excessive shrinkage of the normal dermis, causing depression and thinning of the skin. That is why most of us who perform steroid injections to improve results do so conservatively, starting with low doses. I usually wait 6-8 weeks so that I am not inadvertently "double-dosing" and causing excessive thinning. You can always inject more and stronger, but it is impossible "take it back" if the response is more than anticipated.

Be patient and follow your surgeon's advice; it sounds as if he or she is following good practice by starting conservatively. Good luck!

Kenalog is sometimes useful to dissuade robust inflammation and scarring after rhinoplasty.  Effects are usually noticed in 1 week with maximal results seen in a few weeks.

It’s not unusual for patients to experience significant
swelling following rhinoplasty surgery. This swelling may persist for 12 to 18 months following surgery and
results in the nose being extremely stiff. When this situation arises, steroid injections are occasionally
helpful.It’s important to use steroids
judiciously because they can cause hypopigmentation, spider veins and skin
atrophy.Patients
frequently notice a response to steroids within 2 to 4 weeks of injection. Initially it’s important to utilize small
amounts of steroid to avoid complications. Injections can be repeated at 6 o 8 week intervals.Swelling
usually resolves with the passage of time. For this reason, patients considering steroid injections should consider
the pros and cons of this maneuver before proceeding.
