Usually, newborns have not yet developed all the organs of the body, so the slightest carelessness may cause fractures or illnesses in newborns, and neonatal cremasteric bifida is a common disease among the types of neonatal diseases. What are the types? Occult crestal bifida is the most common and the least severe form of the disease. In babies with occult crestal bifida, there is a small gap between the crestal vertebrae. Most people with occult cremasteric cleft have no symptoms because there is only a cremasteric cleft and no bulging of the spinal canal contents. However, there may be various pathologic changes in the spinal canal at the site of the cremasteric cleft, such as scarring, adhesions, embolism, and combined lipomas causing compression or involvement of the cremaster and nerve roots, resulting in a range of neurologic symptoms. Crestal myelomeningocele is the most severe type of cremasteric cleft. The patient can usually be seen with a skin-covered cyst on the back. This cyst contains tissue as well as nerves. The patient has a damaged or underdeveloped crestal medulla. Depending on the location of the cyst, people with this type of cleft often have some nerve damage or paralysis in certain areas. They may not be able to walk or may be incontinent. Most babies with this type of cleft crest also have hydrocephalus. Hydrocephalus is a condition in which the fluid surrounding the brain cannot drain through blood vessels. Some parts of the brain are damaged before the baby is born, and the fluid is prevented from draining properly. When the pressure increases, the pressure on the brain becomes more severe. Cysticercosis is not as severe as cremastericercosis and is the rarest type of cremasteric cleft. In this case, the membrane contained in the cyst tends to break off. As you can see above, there are three types of neonatal cremasteric bifida according to the condition, and the three classifications are cremasteric bifida, cremasteric bifida and occult cremasteric bifida.
