Mandibular wing osteotomy: technical modification

Sometimes conventional orthognathic treatment cannot achieve the desired results. Mandibular wing osteotomy of the lower border, as first described by Triaca et al,1 comprises the entire inferior border under the inferior alveolar nerve (IAN). It can correct the profile of the lower face without changing the interocclusal relations.2 We present a modification of the technique, which improves safety by reducing the possibility of damage to the IAN.
