Surgically assisted rapid maxillary expansion: current concepts of minimally invasive approaches.

Studies have consistently shown an association of the Le Fort I osteotomy with undesirable adverse events in the nasolabial region, including lengthening and thinning of the upper lip, a reduction in upper vermilion exposure, and nasal base enlargement. Various minimally invasive techniques have been developed based on knowledge collected over recent decades on the aetiopathogenesis of these aesthetic impairments. The common scope of these techniques is to reduce the damage to the facial soft tissues and achieve a sound and spontaneous healing process, avoiding those procedures that are commonly used to counteract undesirable aesthetic changes. This paper provides a summary of the aetiopathogenesis of these adverse events, as well as an overview of current concepts in minimally invasive surgically assisted rapid maxillary expansion (miSARME).
