Surgical techniques used in chin feminization: Literature review and knowledge update

Genioplasty is commonly performed as part of facial feminization surgery. Commonly addressed areas in facial feminization surgery include the chin. According to some authors, 100% of patients request genioplasty surgery in order to feminize their faces. Specific genioplasty techniques (involving generally reduction surgery) applied to transgender patients have been rarely described in the literature. Objective: We aimed to carry out a review of the literature to update the current knowledge on this subject while achieving a comprehensive synthesis of the available surgical techniques for reduction genioplasty in trans Male to Female patients. Conclusion: Reduction genioplasty is frequently performed in facial feminization surgery. Multiple surgical techniques for chin feminization have been described in the existing literature. Reduction genioplasty requires combined work in the sagittal and transverse planes so as to obtain a harmonious result. However, no comparative study on the different surgical techniques has as yet been conducted. Patient satisfaction or surgical complications (which tend to be rare) cannot be related to any specific surgical technique.
