I do not believe my head was subject to any trauma, it's been there as long as I can remember (even asked my mom) . Can anyone tell me what could have caused this? I wonder if it's common and if it has a name? Any viable minimally invasive solutions? I have read Bone Cement and fat injections as being possible ways to even it out. The rest of my face/head is very symmetrical. Aside: It is not a soft spot; it is quite hard.
