Skull Normal Sutures

Adult Skull

Computed Tomography (CT) scan with 3D surface-rendered reconstructions of different views of the newborn skull.

Skull CT Images: Normal overview | Normal vertex and lateral | Normal endocranial and vertex | Normal Vertex - Fontanels | Dolichocephaly and Scaphocephaly | Coronal Synostosis | Anterior Plagiocephaly | Turricephaly | Posterior Plagiocephaly | Deformational Plagiocepahly | Trigonocephaly | Oxycephaly | Computed Tomography

A - Vertex view

Vertex and Lateral

B - Lateral view

  • (a) Metopic suture; (b) coronal sutures; (c) sagittal suture; (d) lambdoid suture; (e) squamosal suture; (f) anterior fontanel; (g) posterior fontanel; (h) sphenoidal fontanel; (i) mastoid fontanel.
  • Cranial vault bones usually ossify from the center to periphery, which results in this “widened” appearance of the sutures in the newborn.

Vertex and Lateral

C - Endocranial skull base view

Shows portions of the occipital bone and sutures

  • (j) Basioccipital; (k) paired exoccipital; (l) supraoccipital; and (m) interparietal. Associated synchondroses are (n) spheno-occipital; (o)anterior intra-occipital; (p) posterior intra-occipital; (q) petro-occipital; (r) occipitomastoid; (s) and mendosal sutures. Note that o, k, p and s are paired structures.

Vertex and Endocranial base

D - Vertex view

Shows the lambda (point of intersection of the sagittal and lambdoid sutures) and bregma (point of intersection of the coronal and sagittal sutures.

Vertex and Endocranial base

E - Endocranial skull base view

Shows the basion (located on the basiocciput, at the midpoint of the anterior margin of the foramen magnum) and opisthion (located on the occipital bone, at the midpoint of the posterior margin of the foramen magnum).
