INTRODUCTION: Skeletal class II occurs when the upper jaw is positioned forward relative to the lower jaw. This facial imbalance can lead to a variety of issues, including an unbalanced profile, difficulty in speech and chewing function, and compromised facial aesthetics. Patients often seek corrective measures to restore facial harmony and function. Orthognathic surgery combined with orthodontic treatment is the main treatment option and offers fundamental solution. However, patients may withdraw from the surgery due to long surgical and down time, high treatment fee and the potential risk of nerve injury.
Osseous genioplasty is a surgical procedure to reposition the chin bone to achieve a more balanced facial profile. Unlike soft tissue procedures that address only the chin’s surface appearance, osseous genioplasty involves reshaping the underlying bone structure, providing more comprehensive and lasting results. The Aim of this study is to determinate how genioplasty aids to improve skeletal class II abnormalities and restore the lower facial profile.

METHODS: The study included 25 male patients and 77 female patients, with an average age of 27.8 years. The sample series was divided according to specific pathologies. All patients underwent surgical procedures and the therapeutic strategy was determined based on the anomalies presented.

RESULTS: 102 patients had a class II dentofacial deformities, 78 patients underwent only genioplasty, 8 patients underwent genioplasty associated with mandibularoplasty, 10 patients underwent genioplasty with malaroplasty and the remaining 6 patients underwent genioplasty associated with mandibularoplasty and malaroplasty.

CONCLUSION: Osseous genioplasty stands as a valuable surgical intervention for individuals seeking to correct maxillary protrusion and achieve a more balanced and aesthetically pleasing facial profile. Thorough preoperative assessment, careful surgical planning and precise execution are essential for successful outcomes.
