The Modular Internal Distraction System or MID
System, developed in conjunction with Cohen,
permits distraction and manipulation of the entire craniofacial skeleton, including the
midface, cranium, and mandible. This allows the surgeon extreme flexibility in osteotomy
design and intraoperative planning (Cohen et
al., 1995, 1997b). Similar to the
DynaForm, this system consists of a universal distractor frame
(15 mm and 30 mm long) with a flexible activation cable, which can be brought through
hidden percutaneous sites in the scalp, pre- or postauricular, or intraoral regions. The
distraction frame is easily assembled to 1.7 mm Mini Wurzburg 3-D Mesh plates by 1.6 mm
connecting screws for intraoperative adaptation of the appliance based on the clinical
application and/or anatomical location.
