[Clinical aspects and intracranial pressure monitoring in cases of traumatic posterior fossa hematoma].
Clinical signs, skull X-P, computerized tomography (CT), continuous monitoring of intracranial pressure (ICP), and serial recording of auditory brainstem response (ABR) were examined in 22 cases of traumatic posterior fossa hematoma. Fifteen of the patients were male and seven were female. Their ages ranged from 3 to 86 years old (mean 35.2 years). ⋯ The hematoma was evacuated in 15 cases. The Glasgow outcome scale administered 3 months after trauma indicated good recovery in 2 cases, moderate disability in 6 cases, severe disability in 2 cases, persistent vegetative state in 1 case and death in 9 cases. It has become obvious that there are many types of CT findings in posterior fossa hematomas, and that continuous ICP monitoring is very important to determine the timing of surgery and to protect against secondary brain damage caused by increased ICP.
