Yes, a revision rhinoplasty can be performed with closed approach, as long as the surgeon is very familiar with that technique. It is possible to reduce the bulbous tip that was not addressed properly with open rhinoplasty through a closed approach by making all the incisions on the inside of the nose. For many examples, please see link below to our closed rhinoplasty photo Gallery
Yes a revision rhinoplasty can be performed using the closed technique on a tip that was not refined enough the first time. I prefer the closed technique over the open technique because I don't like the scar which is on the columella and I have done all my rhinoplasties with the closed technique and have had excellent results. These are rhinoplasties since the 1970's up to now.
