Apparatus for holding a patient's head for surgery thereon so that the head is accessible from ear to ear and from occiput to and including the orbits. The apparatus holds the head clamped between opposed clamp pads. Rear support means engages the posterior of the head and a pair of face pads are adjustably positionable just below the cheekbones of the patient and are lockable in such position. The face pads and rear support means are releasably movable toward one another to hold the head securely between them.
