How is nasal meningeal encephalocele to return a responsibility?

summary

Meningoencephalocele of the nose is a congenital disease. Clinically, it is a congenital malformation caused by the herniation of meninges and some brain tissues into the nasal cavity through the underdeveloped or calcified skull base bone. A round mass with thin skin, wrinkles or pigmentation can be seen near the midline above the external nose of the newborn. How is nasal meningeal encephalocele to return a responsibility?

How is nasal meningeal encephalocele to return a responsibility?

This disease is a congenital malformation of meninges and some brain tissues, which is caused by the undeveloped or calcified nasal bone and hernia. It may be that the ossification of the junction between the membranous bone and the endochondral bone in the craniofacial region is not consistent and the junction is weak in embryo, so that the meninges bulge out from the junction.

Orbital bone defect caused by various reasons. Nasal meningoencephalocele is a congenital malformation of orbital wall bone formation failure in embryo. There are different opinions on how bone loss is formed.

The development of ossification center of sphenoid bone failed. Among them, the theory of incomplete neuroectodermal separation and ossification failure is accepted by most scholars. In addition, orbital bone loss caused by intracranial or orbital inflammation and tumor erosion trauma and surgery can also be secondary to nasal meningoencephalocele.

matters needing attention

The purpose of the operation is to remove the bulging sac, reset or remove its contents, and close the dural defect. The repair should be performed within 6-12 months of birth. The operation should be performed as soon as possible when the capsule wall is thin and tends to be broken. For patients with hydrocephalus, cerebrospinal fluid shunt should be performed before repair.
