Effect of Cranial Suture Autotransplantation From Metopic to Coronal Suture

Journal of Craniofacial Surgery, 1998
The aim of this study was to determine the outcome of autotransplanting part of the metopic suture to a defect in the coronal suture in a pig model and to explore further the concept of functioning and nonfunctioning recipient sites. The authors harvested 15-mm x 10-mm bone grafts, incorporating a part of the metopic suture, in 10 Yorkshire pigs under ...

Mechanical properties of cranial sutures

Journal of Biomechanics, 1990
Many bones in mammalian skulls are linked together by cranial sutures, connective tissue joints that are morphologically variable and show different levels of interdigitation among and within species. The goal of this investigation was to determine whether sections of skull with cranial sutures have different mechanical properties than adjacent ...

Sonography of normal cranial sutures.

American Journal of Roentgenology, 1997
The purpose of this study was to describe the normal sonographic appearance and measurement of normal major cranial sutures in neonates and infants.High-resolution sonograms of sagittal, coronal, and lambdoid sutures were obtained for two autopsy specimens and correlated with histologic sections obtained at identical locations.

Analysis of Cranial Base Suture Fusion Patterns

Journal of Craniofacial Surgery, 2020
Purpose: It is known from both anatomic and radiographic studies that the majority of cranial sutures begin fusing in early adulthood and are fused by late adulthood. However, most of the studies focus on the cranial vault rather than the cranial base. Most clinicians treating patients with craniosynostosis are interpreting the

Fractality of Cranial Sutures

2016
It has long been known that skull suture has a typical fractal structure. Although the fractal dimension has been utilized to assess morphology, the mechanism of the fractal structure formation remains to be elucidated. Recent advances in the mathematical modeling of biological pattern formation provided useful frameworks for understanding this ...

Cdc42 regulates cranial suture morphogenesis and ossification

Biochemical and Biophysical Research Communications, 2019
Cdc42 (cell division cycle 42) is ubiquitously expressed small GTPases belonging to the Rho family of proteins. Previously, we generated limb bud mesenchyme-specific Cdc42 inactivated mice (Cdc42 conditional knockout mice; Cdc42 fl/fl; Prx1-Cre), which showed short limbs and cranial bone deformities, though the mechanism related to the cranium ...

Fractal Dimensions of Cranial Sutures and Waveforms

Cells Tissues Organs, 1992
Two quite different shapes of cranial sutures ostensibly yield fractal dimensions. The rare, intricate sutures yield the more valid fractal dimensions because self-similar scaling provides a double-log plot of negative slope. These sutures are fractals over a range of several r values.

A Fractal Analysis of Human Cranial Sutures

The Cleft Palate Craniofacial Journal, 2003
Objectives Many biological structures are products of repeated iteration functions. As such, they demonstrate characteristic, scale-invariant features. Fractal analysis of these features elucidates the mechanism of their formation. The objectives of this project were to determine whether human cranial sutures demonstrate self-similarity and measure ...

Cranial sutures

Cranial sutures are not of great concern to the modern neurosurgeon, except when abnormalities interfere with the skull's shape and its ability to expand during childhood. It is a commonplace that a craniotomy may cross a variety of sutures without providing any extra difficulty to the operator. The sagittal suture does remain useful as a definition of

Sutural effects of fronto-occipital cranial modification

American Journal of Physical Anthropology, 1996
Maya adult crania from the site of Lamanai, Belize provide a retrospective means of examining growth processes in the cranial vault. The Lamanai population practiced fronto-occipital deformation which is found to be significantly associated with premature sagittal synostosis and wormian bones of the lambdoidal suture.
