Type 2 PEDH: hematoma at both the adjacent site and within the surgical area (B, F). Type 3 PEDH: EDH occurring in remote areas or on the contralateral side of the surgical area (C, G). Type 4 PEDH: hematoma within the surgical field (D, H). The black arrows in A, B, C, and D indicate bone flaps. The white arrows in E, F, G, and H demarcate bone flaps.
