Study of Incidence of Metopism in Adult South Indian Skulls

The metopism is described as persistence of suture from the nasion to the bregma. It can be complete or partial. At birth the frontal bone has a metopic suture which closes approximately by 18-24 months. Cases have been reported where the metopic suture remains patent to the seventh year.367 skulls were observed. In some cases it may persist as a complete suture extending from the nasion to the bregma. Presence of metopism may mimic or can be misdiagnosed as a traumatic fracture.
