Well first of congrats on deciding to go through this procedure. For the most part I hope you have a full understanding of what you're about to go through and I hope for a safe surgery and recovery in your future. Considering you're going with Paley I'm sure you are in absolute best hands. I should also add that I myself am considering not just Paley but also 10 CM gain (obviously 5 in each limb).
In that regard I do have some questions I would love for you to ask Paley in regards to, not just QL, but also general LL under his supervision:
1)What is the expected recovery time for a single bilateral femur LL for 5-6CM look like? And how fast can they return to any sport (this is my first choice mind you)
2)How does he advice his patients when it comes to their proportions and how they might look after surgery? (with regards to legs and torso ration and wingspan)
3)Would he provide arm lengthening for patients who would like to become more proportional?
4)What, if any, long term effects have been caused by this surgery? (yes broad and general question but I'm sure it's very important to ask)
5)Does he expect the price for this surgery to increase in the near future?
6)Have patients generally been happy with their gain in height after their surgery?
Lastly, what does he personally think about this procedure being cosmetic? This is a more personal question regarded to him and is by no means supposed to be a gotcha question, but I'm just generally interested in what an experienced man like Paley would think about this procedure and his understanding of why people would go through with this.
I wish you well mate, hope you have a great journey if you do ultimately decide to go through with this! Thank you and I wish you well.
