Many patients do travel overseas for surgery. In general, I wouldn't advise it if there are capable surgeons in your own country.
I do understand that Singapore is quite expensive for many cosmetic procedures. Part of the reason it is expensive is for patients' safety.
Invasive procedures must be done in a licensed facility, these facilities will have adequate emergency equipment in the event something goes wrong. In cases where you require sedation or general anaesthesia, a qualified anaesthetist will be the one doing that and you will be the only patient they attend to for the entire case. In other countries, one anaesthetist could be overseeing 4 patients at a time while they are under general anaesthesia.
Implants is another component of the cost. The cost of implants in Singapore is higher than our regional neighbours. I don't know the reason for this, but there is quite a big difference.
Surgeon fee is another component of the total cost. In my practice I do try to keep my fee competitive and will try to help my patients as much as possible, but sometimes we can't compete on price with our regional neighbours. What we do offer is safety and certified training.
The main problem with having surgery overseas is the inconvenience of treating any complications if they do occur. Complications can happen to any surgeon, it's a lot less stressful for the patient if they can be handled in their own country with the support of their family and friends.
My advice is to calculate a reasonable budget for the surgery (taking into account travel expenses etc) and try to find a surgeon locally that can help you (you can probably email them to discuss your case prior to consultation).
