MCDO (Multi-directional Cranial Distraction Osteogenesis) Method Treatment for Craniosynostosis

Abstract

  Multi-directional cranial distraction osteogenesis (MCDO) was first developed in Japan as a modified cranial distraction osteogenesis method for treating craniosynostosis (CS). Herein, we report on the use of the MCDO method for the treatment of CS in our hospital.

  Forty patients who underwent MCDO for CS at our hospital were retrospectively reviewed.

  The average age at surgery was 3 years and 8 months (range 5 months-8 years and 10 months), the average number of bone fragments was 17.9 (range 11-26), the average operation time was 5 hours and 6 minutes (range, 2 hours and 55 minutes-7 hours and 12 minutes), and the average volume of blood loss was 307ml (range, 152ml-644ml). Complications included 2 cases of dural injury, 4 cases of infection, and 1 case of frame displacement. The fusion sites included 25 cases of multiple sutures, 12 cases of sagittal sutures, 1 case of unilateral coronal sutures, and 1 case of unilateral lambda sutures. Six patients underwent reoperation ; two after cranioplasty procedures, three cranial distraction osteogenesis procedures, and one MCDO procedure.

  The MCDO method can treat cranial deformities caused by CS in three dimensions, and is indicated for all types of CS ; however, further innovations in surgical methods and postoperative management are needed.
