Quantitative Analysis of Lower Facial Feminization: Cephalometric and AI-Based Evaluation of Surgical Outcomes in Transgender Patients

The authors found that the FFS of the lower jaw significantly enhances feminization outcomes, as validated by cephalometric and AI-based analyses. Especially, gonial width and chin width are crucial factors that affect gender recognition. Thus, to maximize feminization effects in lower jaw surgery, overcorrection of feminine characters of the jawline, such as a tapered chin and slender jaw width, might be advised.
