    [Abstract]Objective：We report a new approach for correcting hypertrophic mandibular angle and masseter through posterior external auricular approach. Methods：This surgical approach is designed in two ways.Operative cutting begains at posterior auricular forsa,then hypertrophic mandibular angle bone and masseter are removed.The great auricalar nerve and facial nerve are protected during operation.Results：We performed 11 cases operations.It is simple safe could be done under local anesthesia.Follow-up period from 6 months to 4 years.All cases got satisfactory post operative result without complication.Conclusion：Posterior auricular approach for correcting hypertrophic mandibular and masseter proved to be a safe,effective and simple surgery.It has many advantages contrasted to external mandibular angle approach or intraoral approach. ......
