ARTICLE HIGHLIGHTS
Research background

Traditional surgical treatment of the supra- and infratentorial acute epidural hematoma (SIEDH) requires a combined supra-infratentorial craniotomy.

Research motivation

To modify the surgery method according to the results of anatomical research.

Research objectives

To analyze the morphological characteristics of the squamous part of the occipital bone (SOB) and introduce a single supratentorial craniotomy for SIEDH.

Research methods

Skull computed tomography scan data from 32 adult patients were collected. The angle of the SOB (ASOB) and the operative angle for the SIEDH (OAS) were measured and analyzed.

Research results

For males, the ASOB was 118.4 ± 4.7 and the OAS was 15.1 ± 1.8; for females, the ASOB was 130.4 ± 5.1 and the OAS was 12.8 ± 2.0. The smaller the ASOB was, the larger the OAS was. Based on the anatomical study, a single supratentorial craniotomy was performed in 8 patients with SIEDH, and the SIEDH was completely removed.

Research conclusions

The single supratentorial craniotomy for SIEDH is reliable and effective.

Research perspectives

It is hoped that the results of this study can improve the efficiency of surgical treatment of SIEDH.
