“…However, their age-adjusted normative data were derived from a large study by Pereira et al in which 2D measurements of frontooccipital diameter, biparietal diameter, and cranial length were defined on radiographs. 36,45 We believe that our data could improve techniques such as those described by Mardini et al, by providing more accurate 2D and real 3D measurements to generate normative models instead of only using limited 2D measurements.…”

“…Such a database, containing age-corrected normative skull geometry data, can also be used directly to tailor the preoperative (virtual) surgical planning in craniosynostosis surgery toward patient-specific normative target values. 24,36 It will also facilitate objective postoperative long-term follow-up of craniosynostosis surgery results, allowing for comparison with age-specific normative 3D geometrical data. 35,50 …”

laboratory investigation J neurosurg Pediatr 16:687-702, 2015 F inite element models (FEMs) of the human head are widely used for studying the biomechanics of traumatic brain injury. 12 FEMs of the human head are virtual computer models representing a human head in great anatomical detail. These models try to offer a better understanding of brain injury tolerance by simulating stress and strain patterns in the skull and brain tissue after impact, mimicking the occurrence of traumatic brain injury as realistically as currently possible. These models try to accurately predict the circumstances that cause traumatic brain injury. To do this, an FEM needs material properties of the brain tissue and skull to correlate a particular applied inertial and contact load to resulting intracranial strains and stresses. Therefore, a correct anatomical representation and use of correct material properties of a child's skull and each intracranial tissue are necessary to develop an FEM of a child's head, capable of realistically simulating the response upon impact. Only such an obJect Finite element models (FEMs) of the head are used to study the biomechanics of traumatic brain injury and depend heavily on the use of accurate material properties and head geometry. Any FEM aimed at investigating traumatic head injury in children should therefore use age-specific dimensions of the head, as well as age-specific material properties of the different tissues. In this study, the authors built a database of age-corrected skull geometry, skull thickness, and bone density of the developing skull to aid in the development of an age-specific FEM of a child's head. Such a database, containing age-corrected normative skull geometry data, can also be used for preoperative surgical planning and postoperative long-term follow-up of craniosynostosis surgery results. methods Computed tomography data were processed for 187 patients (age range 0-20 years old). A 3D surface model was calculated from segmented skull surfaces. Skull models, reference points, and sutures were processed into a MATLAB-supported database. This process included automatic calculation of 2D measurements as well as 3D measurements: length of the coronal suture, length of the lambdoid suture, and the 3D anterior-posterior length, defined as the sum of the metopic and sagittal suture. Skull thickness and skull bone density calculations were included. results Cephalic length, cephalic width, intercoronal distance, lateral orbital distance, intertemporal distance, and 3D measurements were obtained, confirming the well-established general growth pattern of the skull. Skull thickness increases rapidly in the first year of life, slowing down during the second year of life, while skull density increases with a fast but steady pace during the first 3 years of life. Both skull thickness and density continue to increase up to adulthood. conclusions This is the first report of normative data on 2D and 3D measurements, skull bone thickness, and skull bone density for children aged 0-20 y...

“…traduce en una mejor alineación de las esperanzas y expectativas entre los padres y los cirujanos.35, 42,43 En la mayoría de los casos de sutura única, sinostosis sagital no sindrómica, una sola operación es todo lo que se requiere para lograr un resultado estético razonable. Sin embargo, hay un número de pacientes que pueden experimentar la restricción del crecimiento de bóveda craneal postoperatoria sintomática secundaria a la fibrosis de hueso recién formado y pericráneo que reemplaza la sutura sagital extirpado quirúrgicamente, o debido a la fusión de otras suturas previamente abierta que conduce a un aumento de la presión intracraneal lo que exige una segunda operación.…”

ResumenLas craneosinostosis consisten en el cierre prematuro parcial o total de una o más suturas craneales, con una incidencia de 1 de cada 1000 a 3000 nacidos vivos, con mayor prevalencia en varones. Dentro del contexto de las craneosinostosis primaria, la escafocefalia o craneosinostosis sagital es la forma más frecuente y conocida. Al presentarse en un período de vida donde el crecimiento cráneo cerebral es muy importante, ocasiona en los niños una deformidad craneal característica que debe ser corregida, ya que en caso contrario y al ser progresiva, la afectación estética puede ser muy indeseable; las alteraciones funcionales que se pueden presentar van desde aumento de la presión intracraneana, hasta convulsiones, entre otras. Se realizó una búsqueda en bases de datos como PUDMED, RIMA, MEDLINE, MEDSCAPE de revisiones de temas, guías de manejo, artículos y análisis estadísticos, en idioma inglés, donde se encontraron 1.469 referencias. Después de una primera mirada de los artículos a través de sus resúmenes comprendidos en el periodo de tiempo año 2000 a 2014, finalmente se seleccionaron 50 artículos en texto completo abarcando el tema en su totalidad que cumplían los requisitos de búsqueda.Palabras clave: Craneosinostosis; sinostosis; suturas craneales.

AbstractThe craniosynostosis consist of full or partial premature closure of one or more cranial sutures, with an incidence of 1 in 1000 3000 live births, with higher prevalence in males. Within the context of primary craniosynostosis, sagittal craniosynostosis scaphocephaly or is the most common and known form. To occur over a period of life where growth cranium is very important causes in children a characteristic skull deformity should be corrected, since otherwise and being progressive, aesthetic involvement can be very undesirable; functional alterations that may occur include increased intracranial pressure, seizures and others. A search was conducted in databases such as PUBMED, RIMA, MEDLINE, Medscape reviews issues, management guides, articles and statistical analysis, in english, where they found 1,469 references. After a first look at the articles through their summaries included in the period 2000 to 2014, finally 50 articles were selected in full text covering the subject fully meeting the conditions search.
