Skull bone loss

For any rating level, medical records and imaging such as X-rays, CT scans, or MRI reports that document the loss of both the inner and outer tables of the skull are central. The images or radiology reports should show the specific location and dimensions of the bone loss so the size can be compared against the regulatory thresholds.

For the 80% level, records documenting a diagnosis of brain hernia, including neurological examination findings or imaging confirming herniation through the skull defect, would support that rating. For the 50% and 10% levels, precise measurements of the defect area from imaging reports or operative or surgical records are especially important, since the rating turns on whether the area is larger or smaller than specific size thresholds. Neurosurgery or neurology notes that describe the defect size in square inches or square centimeters are particularly useful.

For any intracranial complications that may be rated separately, records documenting those conditions, such as seizure logs, neurological evaluations, or specialist notes, would be relevant to those separate ratings. Statements from you or others describing how symptoms affect your daily life and work can also help document the overall impact.
