“…Japan et al 15 also introduced a novel technique that included a horizontal bicortical incision at the subapical region followed by vertical bicortical incisions and 2 subsequent oblique monocortical incisions starting from vertical incisions and extending posteriorly. This modification has several advantages, such as increased bone contact, absence of steps, lower risk of relapse, and positive effects on patients with sleep apnea.…”

“…Facial contouring at the gonial angle and mandibular plane can significantly improve facial esthetics in such patients. However, osseous genioplasty can also be associated with complications such as inferior alveolar nerve or mental nerve injury, chin ptosis, infection, bone loss, traumatization of the roots of mandibular anterior teeth, bleeding, hematoma, wound dehiscence, mandibular fracture, and irregularity (step/notch) of the inferior border of the mandible, 13,14 which can adversely affect the esthetic appearance of the chin’s soft tissue, and compromise facial esthetics 15 . According to Proffit and White, 11 forward movement of the chin by more than 5 mm can cause notching of the inferior border of the mandible.…”

Background: The chin plays a fundamental role in facial attractiveness. Accordingly, several surgical procedures have been proposed for chin contouring. This study aimed to introduce “B-genioplasty” as a novel genioplasty technique and assess the clinical and cephalometric changes in long-face patients with retrognathia following the novel B-genioplasty. Methods: This is a cross-sectional study. Subjects with class I occlusion increased lower facial height and retrognathia underwent B-genioplasty in this prospective experimental study. Soft and hard tissue cephalometric measurements were made, and the depth of the notch in the lower border of the mandible was measured on lateral cephalograms at 6 months postoperatively and compared with baseline. Patient satisfaction with the outcome was also assessed. Results: Seventeen subjects were studied. Ten (58%) patients underwent rhinoplasty plus genioplasty. All patients were satisfied with the outcome. The step/notch in the lower border of the mandible was not detected in clinical examination in any patient. The mean notch depth was 0.5±0.83 mm on lateral cephalograms. The change in all soft and hard tissue cephalometric parameters was significant at 6 months postoperatively compared with baseline (P<0.001 for all). Conclusion: B-genioplasty caused satisfactory clinical and cephalometric changes in long-face patients with retrognathia, including prevention of step/notch in the inferior border of the mandible, significant reduction of gonial angle, correction of the mandibular plane, and reduction of lower facial height.

“…In addition, chin height can be further controlled by osteotomy of a genial bone segment or augmentation by hair grafting. Transverse problems that produce chin asymmetry with mismatched facial, mental, and dental midlines can be corrected with a horizontally sliding genioplasty [9,10].…”

The chin plays a crucial role as a fundamental structural component that contributes to the overall aesthetics and harmony of the face. Recognizing its central position, medical science has seen the evolution of numerous surgical techniques over the years, all aimed at correcting the range of structural irregularities that can affect the chin. In this contribution, the authors introduce an innovative osteotomy technique, aimed at cases of chin asymmetry in which the skeletal median diverges from the dental median. This technique, called “Tetris genioplasty”, involves performing the classic rectangular osteotomy, but includes an additional vertical osteotomy in order to obtain two distinct segments. Finally, these segments are translocated and repositioned to obtain a realignment between the skeletal median and the dental median. The results were entirely satisfactory for the patients, aligning perfectly with the expected appearance after the operation. Furthermore, no complications were reported, proving the success and safety of the procedure. The Tetris genioplasty aligns itself with this progressive trend by offering a minimally invasive method that nevertheless is able to achieve excellent results with a high impact on the patient’s quality of life, presenting a promising path in the pursuit of optimal aesthetic results with minimized patient morbidity and greater overall safety.

“…2 The three-dimensional topography of the external ear accurately reflects the shape of the internal cartilaginous skeleton. 3 Reproducing anatomical and structural details of the external ear is a challenge for any plastic surgeon and requires a high level of surgical skill and training to fulfill the patient's expectation. Surgical simulation allows development of these skills, reducing mistakes, shortening surgical time, and improving results in vivo.…”

“…2 Failure to perform a much required genioplasty can jeopardize the outcome of hours of an otherwise successful major orthognathic or cosmetic surgery. 3 The slope and nature of rotation of the osteotomized segments dictate the extent of vertical and horizontal changes. 4 In this article, we attempt to introduce a modification to the existing plethora of genioplasty techniques, particularly aimed to rectify a short square jaw into a feminine one.…”
