A total resection manages to regress epileptogenic growth and cure this brain neoplasm. [14] Subtotal resection shows a comparably higher recurrence rate and tumor progression with limited control of seizures. [14]
The elevated ICP may cause compression of the brain, leading to brain damage and other complications. A complication often overlooked is the possibility of hearing loss due to ICP. The mechanism of ICP on hearing loss is presumed that the transmission of CSF pressure to and from the Perilymphatic space through a patent cochlear aqueduct.
Not long after, the seizures started up again and the family was told that Caper would need a second surgery to remove more pieces of his brain. “The first surgery had a 60% chance of giving him ...
