The question of which surgical approach to rhinoplasty is the "best" -- Open versus Closed -- is one of the most frequently debated topics among Rhinoplasty Specialists. Unfortunately, there is not a simple answer to this question. Each rhinoplasty patient is unique, and therefore each rhinoplasty should be unique.
While many plastic surgeons and facial plastic surgeons perform rhinoplasty, very few specialize in secondary (revision) rhinoplasty. Post-rhinoplasty deformities can be very complex and require significant experience to correct. Most revision rhinoplasty specialists perform secondary rhinoplasty via the open approach. This allows the surgeon to directly visualize the deformity.
I recommend that you not only speak with your surgeon about your concerns to see what he or she recommends, but also consult with one or more revision rhinoplasty specialists.
