Comparison of piezosurgery, percutaneous and endonasal continuous osteotomy techniques on a caprine skull model

Osteotomy is a crucial step in rhinoplasty which can have a significant impact on the outcome. In addition to previous percutaneous (external perforating) and endonasal (internal) approaches, piezosurgery has been used in rhinoplasty practice since 2007. This experimental model was planned to compare the three osteotomy techniques.
