In regards to timing of the operation, this will vary from one patient to another and is a decision that should be individualized. If you have reached your physical “maturity”, proceeding with surgery should not be a problem. Parenteral or guardian consent will be necessary for patients under the age of 18. At some point, seek consultation with board certified plastic surgeons who can demonstrate significant experience helping patients in your situation. Ask to see lots of examples of their work and communicate your goals clearly. In my practice, I find the use of goal pictures helpful during this communication process. I hope this, and the attached link, helps.
