Morphology of the development of the sagittal suture of mice.

Syndesmotic sutures of the skull are formed by dense connective tissue and called "open"; they are "closed" by formation of a synostosis between adjacent bones. Open sutures are considered as areas of growth and as hinges. The importance of open sutures during the period of skull growth is reflected by pathological situations in which premature closure of the sutures occurs.

3D-computed tomography: a new method for the evaluation of fetal cranial morphology.

This study is the first presentation of three-dimensional computed tomography (3D-CT) for the in vitro evaluation of the prenatal human cranium. The study was based on CT examinations from 26 aborted normal fetuses between 10 and 25 weeks gestational age. Incremental coronal and transverse CT slices of 1 mm thickness and a threshold segmentation algorithm were used to generate 3D-CT reconstructions (surface-shaded display, SSD) of the cranial bones similar to their anatomical appearance.

Subcutaneous granuloma annulare of the eyelid. A case report.

A rare case of subcutaneous granuloma annulare of the eyelid is reported. A diabetic patient developed a unilateral periorbital tumorous mass. Biopsy revealed subcutaneous palisading granuloma.

[A dental CT study for preoperative assessment of maxillary atrophy].

According to a new technology in the planning of endo-osseous implantation, based on a new CT-software for evaluation of the bone structure of the jaws, anatomico-morphological changes after the loss of teeth are measured much more accurately than with conventional methods like the panoramic intraoral x-ray or conventional tomography. 30 mandibles and 22 maxillae of 36 patients were examined. Besides the topographic course of the mandibular canal and the location of the foramen mentale, the anatomic structures as the important aspects for planning endo-osseous implants are seen more accurately.
