I have a scaphocephalitic skull. I was born 50 years ago before the correcting techniques were commonly used.
May I say to any worried parents out there that from my experience scaphocephaly does not affect one's life chances. I hold an MBA and I work as a health statistician. I have authored a book and regularly give public talks. I am happily married, have an above average income and I am a father to a beautiful boy who has a "normal" shaped skull (although to me my skull is normally shaped).
The effects of this condition are purely cosmetic and from my experience will have no influence on your child's academic or professional attainment.
