I Have a Dent on Left Side on my Forehead Due to Falling Down from Terrace. Solutions How to Remove It? (photo)

It is hard to know whether the contour change was the result of a fracture or soft tissue atrophy following the injury. The only definitive way to determine that would be an examination and possibly a CT scan to look at the bony contour. Either way, this type of issue can be remedied with injectable filler or an implant. Fillers can be injected in the office and leave little, if any evidence, of the procedure. An implant would require a behind the hairline incision for placement and should heal nicely. I hope this information is helpful.

This is probably best treated by filling the dent with your own tissue and therefore does not leave a large scar. 

Hello, 
I see in the photos there is a indention of the bone on the left side. Typically in my practice using soft tissue such as fat grafting or fillers injected in the office don't work and could make it worse. When you have a bone deformity you need to have a bone reconstruction. Typically you will need a CT Head scan to determine the extent of the bone deformity. This can be reconstructed with a couple of methods. One is to use your own bone to fill the defect.  Another option is to create a custom implant to fill the defect.  The last option is to use calcium carbonate hydroxyapatite granules to fill the defect.  I have found the last option to be the best since this requires only small incisions in the scalp and does not require a second donor site deformity such as with bone grafting.  A custom implant can be quite expensive as well.
I suggest finding a craniofacial plastic surgeon who is board certified and understands how to take care of these types of defects.

The pictures are not very good way to make a diagnosis and recommend a treatment. You need in person exam and x-ray, evaluate the forehead then can recommend a treatment plan
