Transantral distraction devices in correction of severe maxillary deformity in cleft patients
Shokhruh Shokirov, Konrad Wangerin
Maxillary advancement by Le Fort I osteotomy in cleft patients has an average relapse of about 40-60 percent. With extraoral distraction devices it is possible to obtain an almost unlimited advancement of the upper jaw. Due to the social problems the retention period is normally reduced to some monthes. A relapse of 10-25 % can be seen in these cases. Le Fort I internal distraction osteogenesis offers an alternative to one-step orthognathic advancement, with advantages of gradual lengthening through scar and earlier treatment in growing patients. The objective of this study was to present our experience in the treatment of maxillary deficiency in cleft patients using transantral internal distraction devices. The distraction procedure was successfully accomplished in seventeen patients. For all the seventeen patients maxillary distraction device designed by Konrad Wangerin was used. The distraction distances were 8 to 24 mm. Preoperative, postoperative, and follow-up (12 and 24 months) lateral cephalogram measurements were compared including angular and linear changes. A good new bone was found that was formed in distraction pitch between lines of osteotomy. After distraction of median facial zone, occlusion and profile of soft tissues were considerably improved. All patients after postoperative time required final orthodontic treatment and their final occlusal relationships were satisfactory. The transantral distraction device is a new option for the treatment of severe maxillary hypoplasia in cleft patients.
Key words: cleft lip and palate patient, distraction osteogenesis, cleft maxillary distraction.
