Open vertical osteotomy in the mandibular ramus is the one surgical option for the correction of mandible deformity. It is easy to assume that this procedure is useful for open reduction of condylar fractures. In this paper we describe a new systematic procedure for open reduction of high condylar fractures. The procedure involves vertical subcondylotomy and a new retractor for subcondylotomy to protect the mandibular neurovascular bundle.
The major points of this operation are the use of vertical condylotomy, removal of the posterior border of the ramus and plating the condylar head with it, and accurate replacement of the posterior border of the ramus with mini plates prepared before osteotomy.
