Abstract: Persistence of frontal suture separating the two frontal bones in the adults is called metopism and the suture is called metopic suture. The fusion of metopic suture starts at around 18 months after birth and is completed by 8-9 years of age. The present study aims at the presence of persistent metopic suture in the adult skulls in various forms between glabella and bregma which may be misinterpreted as radiological fracture. 180 adult skulls ranging from 30-60 years of age group from the department of Anatomy RIMS, Ongole were studied for the presence of metopic suture and their shapes and measurements were tabulated.
