Tetris Genioplasty 2.0: The Evolution of the Technique

Abstract

The chin is a key feature in facial aesthetics, contributing essential projection to the profile. Proper alignment ensures facial harmony, while misalignments can create irregularities that may require surgical correction. Over time, various genioplasty techniques have been developed to address a broad range of asymmetries. Tetris Genioplasty is a novel osteotomy technique designed to improve cases where the skeletal midline does not align with the dental midline, delivering significant corrective results. Building on extensive experience with patients presenting this condition, this technical note introduces Tetris Genioplasty 2.0, a refined version of the original “Tetris” Osteotomy. This enhanced technique minimizes the presence of edges during bone segment realignment, resulting in a more seamless facial profile. This study aims to detail the advancements in the Tetris Genioplasty technique, demonstrating how the 2.0 modification offers an optimized approach to improving facial symmetry and aesthetic outcomes in complex midline discrepancies.
