“…This reduces the risk of unwanted irregularities and enables conservative osteoplasty of the lower border and muscle attachment preservation. We did not perform total inferior border ostectomy as was described in the study by [21], where this technique was presented as superior to T-genioplasty [21]. The authors described total U-shape ostectomy of the whole mandibular complex en block in wider, more asymmetrical chins.…”

Background and Objectives: Correction of lower face asymmetry still remains challenging in maxillofacial surgery. This report describes techniques for the lateral transposition of the symphyseal segment to restore lower face symmetry while maintaining gender-related features in cis- and transgender patients. Materials and Methods: A retrospective review of medical records of 31 patients who attended for esthetic corrective surgery after orthodontic camouflage or orthognathic treatment, or during facial feminization of the lower face between June 2021 and June 2023 was performed. Result: All patients underwent lateralization genioplasty (with or without advancement or setback), either with or without narrowing T-osteotomy supplemented with necessary procedures in order to obtain proper facial balance and desired esthetical effects, such as bichectomy, liposuction, and face and neck lift. The mean asymmetry of the chin was 5.15 mm and was surgically corrected either by single segment lateralization or T-shape narrowing genioplasty depending on the gender and esthetical requirements. No complications were reported. Conclusions: Lateral shift genioplasty serves as a powerful tool in primary and secondary corrective surgery for lower face asymmetry that maintains gender-specific facial features. It may serve either as an additive to orthodontic camouflage or a way to correct previous orthognathic surgery pitfalls. The surgeon performing esthetic genioplasty associated with gender-specific expectations must be trained in facelift and facial liposculpting techniques in order to provide the best results and properly choose the right procedures for the right patients.

“…14 For broad, wide chains, Hirohi 21 proposed a home plate-shaped sliding osteotomy for narrowing genioplasty among the East Asian population; and while this was performed on cisgender patients, similar principles may be applied to feminization of the chin in transgender patients. Finally, in a study by Wang et al, 22 researchers compared the indications and outcomes between total inferior border osteotomy and T-shape genioplasty. This retrospective study found that, compared to the T-shape genioplasty, the total inferior border ostectomy is well suited for a longer, wider, and more asymmetrical chin as this technique is helpful in narrowing the chin and addressing any underlying asymmetry.…”

Background: Facial feminization procedures can be performed to alleviate gender dysphoria among transfeminine or non-binary patients. Moreover, the chin may play an important role in immediate identification and recognition of the face as cis-masculine or cisfeminine, and thus, can be addressed via feminizing genioplasty in the transfeminine population. The purpose of this study was multi-fold: 1) perform a systematic literature review to investigate the current methods utilized to feminize the chin, and 2) study clinical outcomes within an institutional cohort undergoing feminizing genioplasty. Methods: A systematic literature review was conducted in order to survey articles that discussed techniques and clinical considerations when performing genioplasty among transgender females and nonbinary patients. In addition, a retrospective review of such patients undergoing genioplasty by the senior author was conducted. Variables collected included demographic factors, operative details, and postoperative outcomes. Results: Query of the PubMed database resulted in forty articles after removal of duplicates. Eleven studies that discussed surgical technique about genioplasty in facial feminization surgery were selected for analysis and discussion. Commonly discussed techniques were surgical incision, horizontal and vertical reduction, and material used for fixation. Eighty-seven patients were included in our institutional cohort. Approximately half of the patients underwent 2-piece reduction genioplasty, while 8 patients had 1-piece reduction. Horizontal osteotomies and vertical osteotomies were performed in the majority of patients. About one-third of patients received osseous augmentation via centralized osteotomy segments and cranial bone grafts. Conclusions: The core tenets of feminization of the chin lie in the reduction in both horizontal and vertical planes, as well as the creation of harmony with other facial structures. Our analysis presents an updated review of these principles, as well as an in-depth analysis of the senior author’s technique in feminization of the chin in transgender women.
