Why Is My Scar Widening 4 Months Post-Op?

Photos would help. What you consider wide, surgeons might consider excellent, or might think is worse than you do.

Silicone sheeting is a good scar treatment when done properly--worn almost all the time for months.

Your scar will continue to mature over the course of a year. When anything in your outcome is less than pleasing to you, ask your surgeon. Talkative or not, you deserve an answer. Post op care is part of the package you purchased. 

How your scars look after a tummy tuck depends primarily on your genetics (people with darker-skinned genetic backgrounds tend to form worse scars than people with lighter-skinned genetic backgrounds, for instance) and on the technique used during your surgery.  When you pay for a tummy tuck you pay for 'tight' so your surgeon removes enough tissue to make the incision closure 'tight'.  Some surgeons use lots of internal sutures to take some tension off of the scar line and some surgeons do not.  Even when surgeons do use a lot of internal sutures, sometimes the scars widen anyway.  The internal sutures most surgeons use dissolve sometime around 4 months after surgery.  That's when scars tend to widen, which is what sounds like is happening to you.  You won't be able to do anything to help with how wide your scars are.  However, you can help control how 'raised' or 'thick' they are.  Silicone sheets are probably the most effective treatment for this, but only if they're worn 23 hours a day for an extended period of time.  The sheets are inconvenient and some women only wear them 3 or 4 days out of 7, or only at night.  It's pretty common for scars to itch while they're so pink.  Have hope, however.  Usually scars begin to fade a bit around 5 months after surgery and the itching begins to subside then too.  It will take quite a while for you to see your final scar result.  Your 'fancy plastic surgeon that doesn't talk much' should be able to help you through this.  Visit with him/her and ask about it.  His/her staff may also be very helpful.  Hopefully you'll love your look despite the scar!
