Since the beginning of 1998, eleven patients have been treated by osteodistraction to correct hypoplasia of the maxilla and midface of various origins. Among them were six patients who were treated by high LeFort I osteotomies and insertion of subcutaneous intraoral distraction devices in the malar region. In the remaining five patients extraoral distraction devices were applied after LeFort I, II and III osteotomies. Distraction osteogenesis was successful in all cases, resulting in a mean sagittal bone gain measured parallel to the skull base of 9.5 mm (range 4.5-12.0) in the group treated with intraoral distractors and a mean of 19.4 mm in the extraoral distraction group (range 15.0-25.0). All patients were kept under orthodontic supervision before, during, and after osteodistraction. In eight patients long-term cephalometric and clinical evaluation after a mean follow-up period of 24 months in the intraoral distraction group (range 22-26) and 12 months in the extraoral distraction group (range 10-14) show stable results concerning the skeletal and dental relations. Long-term follow-up is necessary.
自1998年初以来,已有11例患者接受了骨牵引治疗,以矫正各种原因引起的上颌骨和中面部发育不全。其中6例患者接受了高位LeFort I截骨术,并在颧骨区域植入了皮下口内牵引装置。其余5例患者在LeFort I、II和III截骨术后应用了口外牵引装置。所有病例的牵引成骨均获成功,口内牵引器治疗组平行于颅底测量的矢状骨平均增加量为9.5毫米(范围4.5 - 12.0毫米),口外牵引组平均为19.4毫米(范围15.0 - 25.0毫米)。所有患者在骨牵引治疗前、治疗期间和治疗后均接受正畸监督。在口内牵引组平均随访24个月(范围22 - 26个月)、口外牵引组平均随访12个月(范围10 - 14个月)后,对8例患者进行的长期头影测量和临床评估显示,骨骼和牙齿关系的结果稳定。仍需进行长期随访。
