A surgical head support to be used for positioning and holding a patient's head during a surgical procedure in the head area. The head support includes an arcuate support having two arcuate arms, each of the arcuate arms having a free end and provided with head engaging elements for gripping the patient's head. The head support further includes a base member provided with concave semispherical recess matching a central portion of the arcuate support. The base member includes two bases adapted to slide one on top of the other perpendicular to a longitudinal axis of the arcuate support. A connecting bolt connects the arcuate support and the base member so that two positions are possible: in the first position, relative motion between the arcuate support and the base member allows rearrangement of the arcuate support with respect to the base member while defining a hemispherical plane and relative motion between the bases is allowed; in the second position, the connecting bolt firmly secures the arcuate support to the base member.
