Dear Editor,
Having read with interest, the recent paper by Lee and Lin [1], “The use of the three-pronged Mayfield head clamp resulting in an intracranial epidural hematoma in an adult”, we would like to make a few observations based on our previously experience [2].
Firstly, the authors said that "intracranial epidural hematomas related to the use of Mayfield has not been published in adults”. We recently published the case of a 19-year-old young admitted for a endoscopic third ventriculostomy who developed an epidural hematoma due to the penetration of the skull by a pin, and review the complications in adult patients, resulting from the use of this type of head holder and found other similar two cases in patients 23 and 24 years of age [3, 4].
Second, the neurosurgeons know the importance of correct positioning of the pins; in the case described by Lee and Lin [1], we can see that the pin was placed on the temporal squama and in this location the skull can be very thin, and should be avoided as possible skull-clamp pin-location sites.
And finally, in our case, the epidural hematoma and the perforation of the skull were placed on the parietal bone, which was very thin due to the chronic intracranial hypertension of the patient [2].
