Abstract
BACKGROUND: Sagittal synostosis is the most common form of single suture synostosis. It often results in characteristic calvarial deformities, including a long, narrow head, frontal bossing, a bullet-shaped occiput, and an anteriorly placed vertex. Several methods for correcting the phenotypic deformities have been described, each with their own advantages and challenges. In this study, we describe a modification of the Melbourne method of total calvarial remodeling for correcting scaphocephaly. METHODS: We conducted a retrospective review of all consecutive patients who underwent total calvarial remodeling using a modified version of the Melbourne technique from 2011 to 2015. We evaluated clinical photographs, computed tomographic imaging, and cephalic indices both pre- and postoperatively to determine morphologic changes after operation. RESULTS: A total of 9 patients underwent the modified Melbourne technique for calvarial vault remodeling during the study period. Intraoperative blood loss was 260 mL (range, 80-400 mL), and mean intraoperative transfusion was 232 mL (range, 0-360 mL). The average length of stay in the hospital was 3.9 days. The mean cephalic indices increased from 0.66 to 0.74 postoperatively (P < 0.01). CONCLUSIONS: A modified Melbourne method for calvarial vault reconstruction addresses the phenotypic aspects of severe scaphocephaly associated with isolated sagittal synostosis and maintains a homeotopic relationship across the calvaria. It is associated with shorter operative times, lower blood loss, and lower transfusion requirements.
