Hello Jazz
The risks are the usual risks involved with any surgery involving general anaesthetic. However I would say that this surgery is a very low risk surgery. Possible risks include anaesthetic complications (unlikely), infection (unlikely), haematoma post op (internal blood clot, not serious, possible), swelling (definate), bruising (definate), scarring (internal and external, definate) etc. In general I have not heard of any major complications with gynecomastia surgery and I wouldn't worry about that side of things.
Cost is around 3500 - 4000 including consultations, compression garments, medications (arnica, vit c etc).
Scarring - I'm assuming you're referring to external scarring. In my case I went with Levick who makes 2 small cuts under the armpits which are barely noticeable. I did not need skin removed. I am not a surgeon so I cannot advise you regarding skin removal, best thing to do is to get a consultation.
The process of my surgery with Levick is he makes 2 small cuts under armpits, through these cuts he inserts liposuction tool and first removes all fat, leaving a clump of gland behind, then uses a tong like tool to pull out the clump of gland. Other people say that his technique is to first use a shredder tool to cut all the gland up and then suck it all out with a liposuction tool, but when he explained his procedure to me my understanding of it was the former.
I only have experience with one surgeonm, Paul Levick, but he has a good reputation.
When you have surgery you should be at a comfortable weight. ie. dont try and lose loads before surgery doing loads of exercise or under eating as during your recovery you will not be able to maintain the exercise and your weight will come back. You should be at a normal, comfortable weight.
Yes you are a good candidate for surgery.
