title: Quantitative morphometric outcomes following the Melbourne method of total vault remodeling for scaphocephaly.
abstract: The Melbourne method of total vault remodeling was developed at The Royal Children's Hospital (Melbourne) to address all phenotypic aspects of scaphocephaly. To quantitatively evaluate this technique, a retrospective analysis was performed on 33 consecutive patients who underwent the Melbourne procedure between October 2004 and June 2007. To monitor outcomes, three-dimensional digital surface photography was used, obtaining 4 anthropometric measurements (cranial length, cranial width, head circumference, auricular head height) preoperatively and postoperatively. To assess the effect on continuing cranial vault development, cranial volume was calculated with computed tomography. Anthropometric measurements were obtained in 27 patients (81.8%), with a mean postoperative follow-up of 8.9 months. Cranial index (width/length) demonstrated an 11.1% improvement. The mean head circumference in the scaphocephaly group preoperatively remained larger than the normative population postoperatively, although the magnitude of difference was decreased, whereas the mean auricular head height demonstrated a 10.5% increase postoperatively, remaining higher than the normative population. Cranial volume was calculated in 30 patients (91%), with a mean postoperative follow-up of 7.9 months. This demonstrated that the mean intracranial volume was significantly higher in the scaphocephaly group preoperatively, and this difference was maintained postoperatively. These results support our belief that the Melbourne procedure is a technique that may be used to correct all phenotypic aspects of scaphocephaly, with no apparent evidence for a detrimental effect on cranial growth.
