[Are there still indications for Wassmund's osteotomy?].

The surgical treatment of anterior alveolar protrusion is usually based on the so-called Wassmund osteotomy. Although the anterior occlusal results are always good, the esthetic impact is very often bad, due to the upper lip recession. However, a good statistical evaluation can be achieved concerning cutaneous movements after surgery, as established by many authors and confirmed by a study particularly focused on lip length and nasolabial angle modifications. It seems mandatory to make a profile prediction tracing for each surgical indication to avoid an irreversible esthetic degradation. In fact, the best surgical indication is very often to perform mandibular advancement with or without associated maxillary surgery.
