Frontal bossing in a 5 year old. Outgrowth or corrective surgery?

Hello experts. As you can see in the attached pictures my daughters frontal eminences are very bulging. Furthermore her forehead is of square shape. I would like to know if this condition will improve with growth or if she will need corrective surgery to even her forehead. At which age would you recommend surgery? How is the procedure and what results can we expect? Thank you for your help.
