L-shaped silicone implants are a quick and easy way to get a more projected (taller), more refined nose. The problem that you are starting to encounter is a common one for many patients that have rhinoplasty with an L-shaped implant. Unfortunately there is a risk of extrusion and infection of the implant. When the skin overlying the implant thins to the point of extrusion, it must be removed asap. In your situation, there’s no need to panic since that has not happened, but the best option is to replace the silicone implant with your own tissue. You will be able to achieve the shape you want, without people noticing you had work done.
