Abstract
Background Dural tenting sutures are difficult to place in the case of keyhole surgery and other craniotomies exposing the temporal base and sphenoid ridge because of difficulty in making small drill holes along the bone edge. Methods The technical difficulty is solved by using a self-drilling anchor screw. A 4-mm self-drilling titanium screw is fixed loosely to either the cortical surface or the cancellous bone of the bone edge to anchor dural tenting sutures. Results The present technique allowed easy placement of dural tenting sutures and efficient epidural hemostasis under the bone edge in more than 100 craniotomies. Conclusions The anchor screw technique allows easy placement of dural tenting sutures along the bone edge in the craniotomy with a limited exposure.
