Do I need a second brow lift and rhinoplasty after 17 years?

Discomfort is a broad descriptive term. Could you elaborate? Some other information you may want to obtain is the type of nasal implant that was used. Was it soft or firm? There are many types of implants but the most typical implants used 17 years ago would have been Goretex or silicone implants. In regards to the cortical tunnel fixation system, the tunnels themselves rarely cause pain or discomfort so many years out. However, permanent sutures may have been used to secure the scalp through the tunnels. Permanent sutures rarely cause problems so many years later with pain. Rather you may have extrusion or granuloma formation. I would rather consider possibility of a low grade infection/reaction around the dorsal nasal implant that is in place. Any infection can seed the surface of the implant and lead to cellulitis and even infection towards the eye (orbital cellulitis) and into the brain. This is not meant to alarm you and in no way am I diagnosing an infection. I recommend you visit with a facial plastic surgeon to have an in person examination.
