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.

“…Another report showed a significant correlation between the somatosensory recovery and the extent of the exposed nerve during SSRO. 32 We suggest that the left-to-right side difference might be attributed to the different osteotomy lines during surgery. The pre-operative orthodontic treatment might cause separate forces on the unilateral mandible, which could also exacerbate the early-post-operative side difference of MDT at the chin.…”

With development of orthognathic surgery and inter-disciplinary cooperative treatment, more and more people with skeletal malocclusion may obtain a better physical appearance. 1 However, not only their quality of life, but also their self-confidence may be improved. 2 Unfortunately, there are several potential complications of orthognathic surgery that cannot be neglected in the information to patients considering treatment, for example, numbness, unexpected fractures, bleeding, osteonecrosis, infections and even partial relapse. 3 Injury to the inferior alveolar nerve (IAN) has the highest occurrence of such complications. 3 Injury to the IAN is typically characterised by numbness of the lower lip and mental skin, and has received the most attention both from surgeons and from

“…One of the most common complications is injury to the IAN and the severity of the damage can range from neuropraxia to neurotmesis, with the latter requiring microsurgical repair [ 2 , 15 , 17 ]. In the literature, the incidence of IAN injury after BSSO ranges from 9 to 85% [ 18 , 19 ]. The neurosensory changes (NSC) after BSSO are usually a combination of axonotmesis and neuropraxia [ 20 ], with the lower lip and chin tip being the most affected areas [ 21 ].…”

Orthognathic surgery involves invasive and major surgical procedures commonly used to correct maxillofacial deformities. Bilateral sagittal split ramus osteotomy (BSSO) is often used to treat dentofacial anomalies related to the mandible, but it can result in various complications, the most common of which is inferior alveolar nerve damage. Nerve damage–induced paresthesia of the lower lip significantly affects patient comfort. Medical treatments such as steroids and vitamin B, low-level laser therapy (LLLT), and platelet-rich fibrin (PRF) can be used as supportive therapies for nerve regeneration after damage. This study aimed to investigate the effectiveness of two different types of lasers in treating lower lip paresthesia after BSSO. This clinical trial was a controlled, single-center, prospective, single-blind, randomized study. Thirty patients were included in the study and randomly assigned to three groups: Group I (laser GRR, n = 10) received transcutaneous and transmucosal GRR laser treatment, Group II (Epic10 laser, n = 10) received transmucosal and transcutaneous Epic10 laser treatment, and Group III (vitamin B, n = 10) received B-complex vitamin tablets orally once a day. Two-point and brush tests were performed six times at specific intervals, and a visual analog scale was used to evaluate pain and sensitivity. Both vitamin B and laser therapies accelerated nerve regeneration. The contribution of the laser groups to the healing rate was better than that of the vitamin B group. Although there was no statistically significant difference between the two laser groups, clinical observations indicated better results in the GRR laser group.

Relationship Between the Quantity of Nerve Exposure During Bilateral Sagittal Split Osteotomy Surgery and Sensitive Recovery

Abstract: The authors estimate a correlation between the recovery time and the quantity of the exposed nerve. There is a high incidence of neurosensory disturbance in the lower lip and chin after BSSO and intraoperative quantity of nerve exposure.
