Mini wing osteotomy: A variant of chin wing osteotomy

Abstract

The mini wing is a variant of the chin wing osteotomy. Its design extends from the chin region to the horizontal branch of the mandible as in a traditional chin wing. However, the posterior most cut ends on the upper part of the mandibular notch. It corresponds to a shortened chin wing that respects the basilar edge of the mandible. Its advantage is the capacity to associate it with a bilateral sagittal split osteotomy (BSSO) in the global management of dento-skeletal deformity. There is no contraindication to the realization of a mini wing. Contrarily to the traditional chin wing, a very low positioned inferior alveolar nerve (IAN) is not a contraindication to the mini wing.
