Frontal bossing is an unusually prominent forehead, sometimes associated with a heavier than normal brow ridge.

Frontal bossing is seen only in a few rare syndromes, including acromegaly, a chronic disorder caused by too much growth hormone, which leads to enlargement of the bones of the face, jaw, hands, feet, and skull.

• Acromegaly
• Basal cell nevus syndrome
• Congenital syphilis
• Cleidocranial dysostosis
• Crouzon syndrome
• Hurler syndrome
• Pfeiffer syndrome
• Rubinstein-Taybi syndrome
• Russell-Silver syndrome (Russell-Silver dwarf)
• Use of the antiseizure drug trimethadione during pregnancy

There is no home care needed for frontal bossing. Home care for disorders associated with frontal bossing varies with the specific disorder.
