An infant or child with frontal bossing generally has other symptoms and signs that, when taken together, define a specific syndrome or condition. The diagnosis is based on a family history, medical history, and thorough physical evaluation.

Medical history questions documenting frontal bossing in detail may include:

• When did you first notice that the forehead appeared unusually prominent?
• What other symptoms are present?
• Have you noticed any other unusual physical characteristics?
• Has a disorder been identified as the cause of the frontal bossing?
• If so, what was the diagnosis?

Laboratory studies (such as chromosome studies, enzyme assays, x-rays, and metabolic studies) may be ordered to confirm the presence of a suspected disorder.
