Chin reduction - skin removal?

I had a chin reduction via burring 2 years ago he didn't remove any skin and i wore a tight chin support for a week as my doctor said this would allow the skin to attach back to the chin however I feel like my chin looks bigger, it's smaller on profile but from the front it looks longer and square and the skin hangs down and looks a bit saggy I asked him about removing skin prior to op and he said that this doesn't happen. Is this correct and would he be able to relive some skin to improve this?
