ABSTRACT
Hiroshi Kashimura, Kuniaki Ogasawara, Yoshitaka Kubo, Kenji Yoshida, Atsushi Sugawara, Akira OgawaDepartment of Neurosurgery, Iwate Medical University School of Medicine, Morioka, Iwate, JapanAbstract: Conventional burr-hole buttons sometimes do not fit the burr hole well due to the curvature of the surrounding bone. An irregular surface at the border between the button and the surrounding skull may appear unaesthetic. The major problem is the difference between the curvature radius of the skull and the burr-hole button in contact with the skull. To solve this problem, the authors designed a button made of hydroxyapatite ceramic to snugly fit the burr hole. The specifications of this device and its clinical application are described here.Keywords: hydroxyapatite ceramic, bone curvature, burr-hole button, craniotomy, cosmetic outcome
