[Changes in the mandibular growth after ramus osteotomy in rats].
A comparison is made between mandibular growth of the operated side and the unoperated side after vertical ramus osteotomy by measurements of the area and linear distances of bilateral mandibles, and digital image processing technique from the radiographs. The results show that slightly retarded growth of the mandible of the experimental side in growing Wistar rats occurs after osteotomy in the mandibular ramus, but obvious asymmetry is not found Deficiencies of mandibular growth in the operated side are similar in both groups of upward and downward repositioning of the proximal segment.
