Diagram demonstrating position of standard burr holes (1, temporal (above zygoma), 2 frontal (over the coronal suture, approx 10 cm behind and in the mid-pupillary line) and 3 parietal (over the parietal eminence). CT Images correspond. A posterior fossa burr hole can be used in the extremely rare cases of posterior fossa extradural haematoma.). See text for indications, requirement for imaging and requirement for neurosurgical discussion.
