What causes scar tissue formation after a rhinoplasty?

Rhinoplasty requires both incisions and dissection of tissue planes.  Following rhinoplasty the normal healing process at the incision sites and dissection planes heals through a well-described series of steps including blood vessel ingrowth, cell migration and collagen production.  This is essentially the same process involved in scar production, except in the formation of excessive scar tissue the process goes "too far".  In the healing phase following rhinoplasty any insult such as trauma, infection, allergic dermatitis or sun burn can result in increased inflammatory stimulus resulting in excessive collagen production and therefore excessive scar formation.  Blunt trauma following rhinoplasty has a risk of triggering excessive scar formation only if it is severe enough to result in bleeding or obvious swelling following the trauma.Mario J.

Hello,If you are referring to scar tissue that causes an unanticipated outcome such as fullness around or above the tip, it is likely due to excessive bleeding at the time of surgery.  Although possible, minor traumas post surgically are unlikely to cause this problem.Best of luck!

First of all swelling is not the same thing is scarring. Minor trauma that you describe will have no long-term influence on the operation. Eventually when the swelling subsides the actual scarring will be very minimal.
