A modified sagittal split ramus osteotomy for correction of mandibular deformity

Objective To explore a method of modified technique of sagittal split ramus osteotomy (SSRO) and to study the possibly more appropriate and effective methods for correction of mandibular de-formity. Methods 195 patients suffering from mandibular anomaly or accompanied by other deformities have been operated on by the modified or classical technique of SSRO. Results In the group of 105 cases treated by modified SSRO and the group of 90 classical SSRO, all the patients acheived excellent results. There was no statistic significance between the two groups. No complications occured, such as postopera-tive relapse, significant bleeding, postoperative infection, and others. Conclusion Since modified tech-nique of SSRO has more advantages than conventional classical technique, such as more area of bony con-tact, shorter-time operation, easier process: it is the preferred method for the correction of mandibular deformity. Accompanied by regularity and in time pre- and post-operational orthodontic therapy, it will be more widely used in the future.
