[Compression-hypoxic birth injuries and skull configuration]

The fetus has birth traumatic, compression-hypoxic, and hypoxic-ischemic brain lesions during childbirth. There are problems in their differentiation in clinical and anatomopathological practice. It is proposed to divide birth traumatic injuries into two types: 1) obvious traumatic injuries and 2) compression-hypoxic traumatic injuries. Signs of compression-hypoxic birth injuries were found in 24.4% of the examined fetuses and newborns delivered via vacuum extraction and application of obstetric forceps. This allows compression hypoxia to be attributed to birth injury rather than to hypoxic-ischemic encephalopathy. It is proposed to use the concept of compression-hypoxic birth injury. The morphological signs that are characteristic of this type of birth injury are given. It is indicated that the impact of physical forces on the fetal head is mediated by its configuration. The mechanisms of birth traumatic injuries are systematized. The pathological configuration of the fetal head is shown to be of importance in explaining the cause of birth injury.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
