Background: Routine and popular conventional genioplasty procedure is often curvilinear, requires lower border extension below, and behind the mental foramen, which after advancement has a tendency to produce step deformity, butt contact, hence nonunion, instability, and increased relapse tendencies. The present technique is aimed to study the new sagittal genioplasty technique and its efficacy to overcome the above-mentioned drawbacks of conventional genioplasty. This technique also aids in correcting mild-to-moderate breathing irregularities. Materials and Methods: A total of 10 patients included in this study. The comparative analysis of the displacement of the chin in vertical and horizontal directions following surgery was evaluated by measuring the difference between preoperative, immediate postoperative, 3 and 6 months postoperative on lateral cephalometric radiographs. Results: The study of new sagittal chin advancement results showed an advantage over conventional technique in terms of esthetics outcome (no jowl), easy to perform without damaging the mental nerve, superior healing with less relapse, and better surface area contact. Conclusion: In this study, the new technique of sagittal genioplasty overcomes the disadvantages of conventional genioplasty. However, this technique is best suited for patients who require straight or moderately vertical augmentation advancement genioplasty and is not suitable for asymmetry corrections, i.e., centering genioplasty and double sliding genioplasty.
