A modified intraoral and extraoral approach osteotomy for the prominent mandibular angle

A prominent mandibular angle (PMA) is a relatively common condition in Asians, and surgeons typically use the intraoral approach to treat it. However, the approach can have many drawbacks due to the limited operative field and view. The procedures of the osteotomy are not easily performed, and an exact resection is difficult. In addition, major complications can occur readily. This article presents a modified osteotomy method for the PMA that avoids these disadvantages and makes the procedure easier to execute.
