Osteotomy of the pterygomaxillary junction

In an attempt to overcome the faults of the Le Fort I type of operation, the pterygomaxillary junction was experimentally fractured with the classical Obwegeser osteotome and the results compared with those obtained with an osteotome of a design based upon the anatomic pecularities of that area. The modification proved to be successful and justified a clinical trial; the results were compared with those obtained on the dissecting room specimens.
