Objective:

To investigate the clinical outcomes of performing CSDH drainage and middle meningeal artery occlusion through the same cranial burr hole.

Approach:

• Study Design: Retrospective analysis of 116 patients with CSDH who underwent surgical treatment from January 2021 to June 2025, with 41 in the observation group and 75 in the control group.

Key Findings:

• The observation group had a significantly shorter drainage duration and hospitalization duration (p < 0.001) compared to the control group.
• At 1 month postoperatively, the observation group had a significantly less hematoma residual volume (p < 0.001).
• The hematoma recurrence rate at 6 months postoperatively was significantly lower in the observation group (4.9%) compared to the control group (20.0%, p = 0.030).

Interpretation:

The combined surgical approach led to better outcomes in terms of drainage efficiency and reduced recurrence rates compared to traditional methods.

Limitations:

• The retrospective study design may introduce selection bias, and the limited sample size may affect the generalizability of the findings.

Conclusion:

The combined approach of BHD and MMA occlusion through a single point under 3D reconstruction technique shows potential for reducing hematoma recurrence.
