Core Tip

Core Tip: Traditionally, surgical treatment of a supra- and infratentorial acute epidural hematoma (SIEDH) requires a combined supra-infratentorial craniotomy. We analyzed the morphological characteristics of the squamous part of the occipital bone (SOB) and found that the operative angle for the SIEDH was negatively correlated with the angle of the SOB. These morphological characteristics of the SOB make it possible to treat SIEDH with a single supratentorial craniotomy. Based on the above findings, we used a single supratentorial craniotomy to treat SIEDH, and achieved satisfactory results.
