Three-dimensional Cranial Suture Morphology Analysis

The aim of the study was to assess the normal and synostosed coronal cranial sutures morphology at an ultrastructural level. Different operative specimens of human coronal sutures were collected. Three-dimensional reconstruction of the microcomputed tomography (micro-CT) slices were obtained and compared with the representative histologic sections. The micro-CT scanning provides a three-dimensional view of the sutures at a microscopical level thus allowing to establish the stage of development and the bone morphology. The micro-CT has the advantage of being able to image more slices than the normal histology without any damage to the analyzed specimens. Micro-CT is a powerful tool in the craniofacial area that allows us to obtain many structure-orientated slices and in conjunction with the histologic sections provides an overall thorough quantitative analysis of all cranial sutures.
