Age-related Outcomes of Chest Masculinization Surgery: A Single-surgeon Retrospective Cohort Study.

[UNLABELLED] Many transmasculine individuals face chest dysphoria, an emotional distress associated with breast development. The definitive management for reduction of existing breast tissue and alleviation of chest dysphoria comes in the form of chest masculinization surgery. Over the years, a substantial increase in the number of youth seeking gender-affirming chest masculinization surgery was observed globally. The study was hypothesized to answer the question as to whether the age limit of chest masculinization surgery should be lowered to include adolescents.

[METHODS] A retrospective cohort study was conducted, based on the experience of a single surgeon over a period of 20 years.

[RESULTS] Two-hundred eight patients were included in this cohort. Patients were divided into two equal groups based on their age. No statistically significant differences between the groups were observed in terms of resected breast tissue ( = 0.62 and 0.30, for the right and left breast, accordingly), auxiliary liposuction ( = 0.30), liposuction volume ( = 0.20), procedure ( = 0.15), postoperative drains ( = 0.79), and surgery duration (P = 0.72). Statistically significant differences were found in the 18 years or younger group, with lower rates of complication ( < 0.001), lower rates of revision surgery ( = 0.025), and higher satisfaction rankings ( < 0.001). Apart from age, no other factors were found to potentially explain the different rates of complications between the age groups.

[CONCLUSION] Patients aged 18 or younger opting for chest masculinization surgery experience fewer complications and revision procedures while having higher satisfaction rates with the surgical outcome.
