ABSTRACT
Background: The Metopic Suture is a suture seen between the two halves of frontal bones which ossifies in membrane from the two primary centres. The fusion of the metopic suture starts at around eighteen months after birth and completed by six years of age. Persistence of this suture in adult is called metopism. It may be misinterpreted as fracture in x-ray.
Materials and Methods: This study was conducted with 133 human adult dry skulls. They were inspected at norma frontalis for presence of metopic suture. They were classified as complete and incomplete. The incomplete ones were again classified as ‘V’,’U’,’Y’ and linear type.
Observation and Results: Out of 133 skulls 84 were found to have no metopic suture, one had complete suture (extending from glabella upto bregma ),14 skulls were manifested to have ’V’ shaped suture,11 skulls were discovered to have ’U’ shaped suture,6 skulls were revealed to have ‘Y’ shaped suture and remaining 17 showed linear metopic suture in the midline.
Conclusion: The present study was conducted to note the incidence of metopism in adult skull which may be useful in the field of Neurosurgery, Radiology and Forensic Medicine.
Key words: Adult skull, Metopic suture, Metopism, Ossifcation.
