Cranioschisis
Cranioschisis
Cranioschisis (pronounced: kray-nee-oh-SKIH-sis) is a rare congenital condition characterized by a defect in the skull formation, leading to a fissure or gap in the skull.
Etymology
The term 'Cranioschisis' is derived from two Greek words: 'kranion' meaning skull, and 'schisis' meaning split.
Definition
Cranioschisis is a severe form of neural tube defect (NTD), where the bony case of the skull fails to close completely. This condition often leads to exposure of the brain and can be associated with other anomalies such as anencephaly, where a major portion of the brain, skull, and scalp is absent.
Symptoms
The primary symptom of cranioschisis is the visible defect in the skull. Other symptoms may vary depending on the severity of the condition and the presence of other associated anomalies.
Diagnosis
Cranioschisis can be diagnosed prenatally through ultrasound imaging. Further diagnostic tests such as MRI or CT scan may be used to assess the extent of the defect and any associated conditions.
Treatment
Treatment for cranioschisis is primarily surgical, aiming to close the defect in the skull. The prognosis depends on the size and location of the skull defect and the presence of other associated conditions.
