“…Internal distractors are more comfortable for the patient. Rachmiel et al have recently demonstrated the long-term stability of internal maxillary distraction in a large series;[ 13 14 ] however, positioning is very demanding since a precision mistake will lead to a wrong final position of the distracted maxilla. 3D planning and patient-specific guides allow for a precise performance of osteotomies and distractor placement.…”

“…There are several reports on postoperative changes after maxillary distraction using RED devices,[ 10 11 ] but not so many using internal distractors[ 3 12 13 14 ] which are smaller and more comfortable for the patient. Results have been evaluated with 2D lateral cephalometries; only recently some publications have stressed the benefits of three-dimensional (3D) planning in maxillary distraction.…”

Introduction: Maxillary distraction may be used to treat severe maxillary hypoplasia in cleft lip and palate (CLP) patients. Three-dimensional (3D) planning has been shown to increase the accuracy of distraction and reduce operative time and complications. The aim of the study was to measure the accuracy of internal maxillary distraction after 3D planning in CLP patients, to add evidence to validate the virtual osteotomy and distraction procedure. Materials and Methods: Eleven CLP patients with severe maxillary hypoplasia underwent maxillary distraction using internal distractors. Virtual planning was used to design the osteotomies, the distractor position, and the distraction vector. Cutting and positioning guides transferred this information to the surgical procedure. Four to six month postoperative computed tomography-scan was done before distractor removal; anatomical reference points were compared to the virtual planning to determine accuracy. Results: A high accuracy (point dislocation <1.5 mm) was found in 90% of the points of the surface of the maxilla; the majority of the zygomatic screws were placed within a distance of 0.8–1 mm from their planned position. Discussion: The high accuracy achieved through virtual planning promotes optimal distractor placement; a customized distraction vector has a direct effect on the final position of the maxilla.
