Title: 2/3 osteotomy for lengthening the mandible in dogs by gradual distraction. Author: Miao J, Li G, Zhao P, Chen G, Teng L, Ling Y. Journal: J Craniomaxillofac Surg; 1997 Dec; 25(6):301-4. PubMed ID: 9504305. Abstract: Successful lengthening of the mandible by gradual distraction has been reported previously. There are various methods for osteotomy before distraction osteogenesis. In this paper, a new type of osteotomy, performed on growing dogs as a model, is reported. Ten mongrel dogs, aged 6 months, were studied. A unilateral 2/3 osteotomy was performed, and an external lengthening device was fixed to the mandible perpendicular to the osteotomy. Seven days after the operation, the mandible was lengthened by 1 mm per day. The dogs were sacrificed for histological study at the end of the distraction on days 14, 28, 56 and 120 following completion of the distraction.[Abstract] [Full Text] [Related] [New Search]
