There are no procedures available to reconstruct the normal cranial shape irrespective of the type of cranial deformity with minimal patient stress and morbidity. To achieve dynamic total skull remodeling, we considered a new remodeling concept and developed a new procedure by combining morcellation craniotomy and distraction osteogenesis, termed the MoD procedure, and designed a distraction device, namely the angle variable distraction (AVD) system. Between 2000 and 2009, we treated 41 patients with craniosynostosis (28 and 13 cases of isolated and syndromic craniosynostosis, respectively) by using the MoD procedure with the AVD system. Compared with the conventional methods, the mean operative time was significantly shorter, and the mean transfusion volume was significantly less for the MoD procedure. In all the patients, good cranial shape and adequate cranial volume were achieved without serious complications. In conclusion, the MoD procedure with the AVD system is safe, effective, and reliable for dynamic total skull remodeling with minimal morbidity. It could be used to improve the previous surgical concepts for treating craniosynostosis.
