Objectives: 1. Discuss diagnosis of chin deformities
2. Discuss treatment planing after appropriate dento-facial analysis
3. Demonstrate surgical steps in osseous genioplasty

Introduction: Management of aesthetic chin disorders presents a broad range of options from surgery to fillers. Optimal management requires a knowledge of dento-facial aesthetics. Osseous genioplasty is one of the most powerful procedures available in aesthetic treatment of the deficient chin, yet is fading from clinical use.

Materials / method: This procedure will be demonstrated in a step by step video.

Results: Results will be shown in 2 operative patients

Conclusion: Osseous genioplasty is a simple, but powerful procedure and should be a part of the surgical armentarium for chin deformities.

Objectives: To show the advantages of guided surgery for mentonian deformities over conventional surgical techniques: a comparative study.

Introduction: Genioplasty as an isolated surgical technique is a highly demanded procedure in the maxillofacial surgery area. Advances in facial reconstructive surgery have been associated with less morbidity and more predictable results. In this paper, “conventional” genioplasty and genioplasty by means of virtual surgical planning (VSP), CAD-CAM cutting guides, and patient custom-made plates are compared.

Materials / method: A descriptive observational study was designed and implemented, and 43 patients were treated, differentiating two groups according to the technique: 18 patients were treated by conventional surgery, and 25 patients were treated through virtual surgical planning (VSP), CAD-CAM cutting guides, STL models, and titanium patient-specific plates.

Results: The operation time ranged from 35 to 107 min. The mean operative time in the conventional group was 60.06 + 3.74 min.; in the custom treatment group it was 42.24 + 1.29 min (p < 0.001). In cases of chin rotation due to asymmetry, guided and personalized surgery was superior to conventional surgery (p < 0.01). The mean hospital stay was equal in both groups. A decrease in surgical complications was observed in the group undergoing VSP and customized treatment.

Conclusion: Multi-stage implementation of VSP with CAD-CAM cutting guides, STL models, and patient-specific plates increased the accuracy of the genioplasty surgery, particularly in cases of chin asymmetry, reducing operation time and potential complications.
