Hydrocephalus in adults. Ultrasound detection through surgically created cranial defects

For 15 men who had undergone neurosurgery, ultrasound of the brain through the surgically created cranial defects identified the status of the ventricles in 15 of 17 total examinations (88%). Two failures involved patients with cranial defects in the frontal region. Assessments were all correct when correlated with computed tomography.
