For those of you searching for highly experienced plastic surgeon in Singapore I recommend Dr Por.
You can post your questions in his website, and get quick replies (I think he is currently in India on official duty - but should be back this week)

Besides plastic surgery, Dr Por is also an expert in cleft lips reconstruction.
His price is reasonable and if you ask he may even give you a breakdown of the operation costs.
I highly recommend him.
