ABSTRACT:
A skull distraction and monitoring apparatus and method includes multiple mini-fixation plates fixedly attached to a craniofacial skeleton of a rabbit on either side of the coronal suture. Tubular members are fixedly attached to the plates. A distraction portion of the apparatus is fixedly attached to the tubular members. The distraction portion includes jackscrew assemblies that traverse the coronal suture and span thereabove. When the jackscrew assemblies are turned, the distraction portion of the apparatus expands, distracting an anterior skull portion and facial portion of the rabbit from the remainder of the skull. The distraction portion also includes registration apertures that are adapted to cooperate with a skull positioning assembly for repeatedly holding a skull in a particular position so that the skull expansion may be accurately monitored. A method for surgically attaching the apparatus, expanding the skull and monitoring skull expansion is described.
