Cranioschisis is a medical term that refers to a congenital cranial defect in which the bones of the skull fail to close properly, leading to exposure of the brain. The spelling of this word can be explained using the International Phonetic Alphabet (IPA). It is pronounced as /kræniəʊˈskɪsɪs/, where the stress is on the second syllable. The first part 'crani-' is derived from the Greek word for skull, while 'schisis' comes from the Greek word for splitting. Thus, cranioschisis literally means a split in the skull.
Cranioschisis is a medical term that refers to a rare congenital condition characterized by the incomplete closure or fusion of the bones in the skull during fetal development. The term is derived from the Greek words "cranio" meaning skull and "schisis" meaning a split or division.
In normal circumstances, the bones of the skull fuse together to protect the developing brain. However, in the case of cranioschisis, this fusion process is disrupted, leading to an opening or gap in the skull. This condition often results in a visible defect on the baby's head, with exposed brain tissue or meninges, the protective membranes that cover the brain.
Cranioschisis can occur in different forms and varying degrees of severity. It may occur as an isolated defect or may be associated with other malformations in the brain or other parts of the body. The cause of cranioschisis is not well understood, but it is thought to be a complex interplay of genetic and environmental factors.
Diagnosis of cranioschisis is typically made prenatally through ultrasound or other imaging techniques. After birth, immediate medical intervention is necessary to protect the exposed brain and prevent infection. Surgical repair or reconstruction of the skull is often required to cover the open area and restore normal brain protection.
The long-term prognosis for individuals with cranioschisis varies depending on the extent of the defect and associated abnormalities. Proper medical management, ongoing monitoring, and supportive care are crucial in improving outcomes for individuals born with cranioschisis.

The word Cranioschisis comes from the fusion of two Greek roots: cranio- which means skull or head, and schisis which means split or cleft. So, the etymology of Cranioschisis can be understood as a condition or defect characterized by the splitting or cleft of the skull.
