Study of Metopic Suture in Dry Human Skulls

Frontal bone develops from two halves connected by metopic suture. Metopic suture usually gets obliterated in the 1st postnatal year. But it may persist in small area in the adult skulls. The present study was undertaken to observe the presence of the metopic suture in the collected adult human skulls obtained from Nepal Medical College.57 complete human skulls were taken from the Department of Anatomy, for the study of metopic suture.42 crania had the metopic suture, out of which 4 crania were noted with the metopism. The partial sutures were of linear, V-shaped and double varieties with the highest frequency of the linear (31.6 %) followed by double sutures (28.1 %) and the least observed were V-shaped sutures (7 %). The length of the complete metopic suture was calculated to be 12.82cm.
