Sagittal Suture of the Human Cranium and the Time of Closing

Abstract

SUMMARY:The observation of the stage of ossification of the sagittal suture has been adopted as possible approach of age evaluation in anthropology and legal medicine, as area of cranial pathologies: craniosynostosis and scaphocephaly and as diagnosis resource in tomographies. Regarding it, we found many controversies in the specialized literature, thus we decided to accomplish this research with the following objectives: to examine the ossification of the external surface of the sagittal suture, observing eventual differences due to age, sex and ethnic group. Our material consists of 88 dry craniums of variable ages, both sexes belonging to the ethnic groups: white and black. In that material we observed that: with progression of age, the relation between age and stage of ossification of the sagittal suture stops existing. The statistical analysis didn't demonstrate significant differences between sexes and ethnic groups in the stages of ossification of the sagittal suture. The ossification of the sagittal suture starts developing from the posterior third.

Macroscopic Cranial Suture Closure in An Adult Population: Is It Reliable for Estimating Age?

“…ilar pattern were seen as found in the studies done by Sahani et al[12], Alves et al[14], Gaur et al[15], Jangietrew[16], and Perizonius[17]. Although a higher number of cases will give more constructive results, the present study has a fair number of cases to infer a conclusion.In our study, we observed that in ectocranial su-ture closure, Sagittal suture showed mean obliteration score of 0.02 in persons 21-30 while it was 3.21 in the >60 age group.…”

“…Este individuo presenta una dispar morfología craneana donde sobresale el frontal alto y proyectado, forma oblonga, suturas obliteradas (Figura 5), así como las dimensiones e índices calculados (Tabla 2), que parecen ser consistentes con las características que Trad y Rosique (2005) describen como posibles casos de escafocefalia. Esta condición patológica, de origen congénito, se desarrolla a partir de la obliteración prematura de la sutura sagital (Alves et al, 2009;Barnes, 2008), traduciéndose en el alargamiento del cráneo con estrechamiento bitemporoparietal y protuberancia frontal y occipital (Waldron, 2009). De las sinostosis del cráneo es considerada la más favorable, dado que produce una menor afectación neurológica (Krivoy et al, 1999), siendo preponderante en individuos de sexo masculino, asociándose comúnmente con factores congénitos (Barnes, 1984).…”
