Final answer:
Hydrocephalusis the most common extraneural complication of myelomeningocele.
Step-by-step explanation:
Hydrocephalus is the most common extraneural complication of myelomeningocele. Myelomeningocele is a severe form of spina bifida, a birth defect where the spinal column does not close properly, causing a protrusion of the meninges and spinal nerves, leading to various neurological impairments. Managing myelomeningocele often requires surgical intervention to close the opening or remove the cyst to prevent further damage or infection.
With the central nervous system being affected in myelomeningocele, complications such as hydrocephalus can become apparent, which is an accumulation of cerebrospinal fluid within the brain, potentially leading to increased intracranial pressure and requiring treatment such as shunt placement to relieve the pressure. While life expectancy may not be significantly impacted, individuals with myelomeningocele can experience lifelong challenges due to the neurological and physical effects of the condition.
