Are irregularities normal after browbossing reduction?

[Isabel2006]

Hello,
Since I had my forehead reduced 6 months ago I'm noticing some irregularties like two small I had brow bossing reduction and hairline lowering in august of 2013 and I'm starting to notice a 2 small dents  at the beginning of each eyebrow and small bump of bone in the middle. It's not really noticible except in some lighting. Is this common after forehead surgery?
I would like to get more forehead contouring anyway can this be fixed or am I likely to get more irregularties like this after a 2nd time?

Any information would be appreciated.

Thanks and I'm sorry for all the questions I've been asking lately!

Do you have any pictures to better understand what it looks like? I think some degree of irregularity is not unusual, especially if your frontal bone was fractured and set back.
