In the nonsyndromic cases, a positive family history is found in 2 % of the cases with sagittal suture closure and in 6 to 11 % of the cases with coronal suture closure.

Common physical malformations are : craniosynostosis of the coronal suture ( s ), orbital hypertelorism, frizzy curled hair, longitudinal ridging and / or splitting of the nails, and facial asymmetry.

Premature fusion of a coronal suture one of the structures that run from each ear to the sagittal suture on top of the head may force your baby's forehead to flatten on the affected side.
14.
In humans, the cephalic disorder is known as "'flat head syndrome "', and results from premature fusion of the coronal sutures ( see craniosynostosis ) or from external deformation ( see plagiocephaly ).
15.
Examples include : trigonocephaly ( fusion of the metopic suture ), brachycephaly ( fusion of the coronal suture and lambdoid suture bilaterally ), dolichocephaly ( fusion of the sagittal suture ), plagiocephaly ( fusion of coronal and lambdoidal sutures unilaterally ), and oxycephaly or turricephaly ( fusion of coronal and lambdoid sutures ).
16.
Examples include : trigonocephaly ( fusion of the metopic suture ), brachycephaly ( fusion of the coronal suture ), dolichocephaly ( fusion of the sagittal suture ), plagiocephaly ( unilateral premature closure of lambdoid and coronal sutures ), oxycephaly ( fusion of coronal and lambdoidal sutures ), Kleeblattschaedel ( premature closure of all sutures ).

These bones are connected by the coronal suture between the frontal and parietal bones, the sagittal suture between the two parietal bones, and the lambdoid suture between the parietal and occipital bones . " Vertex baldness " refers to a form of male pattern baldness in which the baldness is limited to the vertex, resembling a tonsure.

Skull resonance " per se " seems excluded by plausible-sounding claims that the skull resonates at much higher frequencies ( Google says it's in [ http : / / multi-science . metapress . com / content / u64401721m37k817 / here . . . ), yet my personal experience is that particularly low-pitched, dizzying infrasound from about 1 / 2 hour exposure to a nearby Bobcat excavator on a few occasions causes my coronal suture to get sore, which never occurred from any other cause, so I am perversely reluctant to concede the point . talk ) 16 : 04, 2 January 2013 ( UTC)
