Updates on metoidioplasty.

AIMS

Metoidioplasty presents a variant of phalloplasty in transmen who require simple and safe genital gender affirmation surgery (GAS). The aim is to evaluate updates on the technique, as well as personal experience.

METHODS

The surgical steps of metoidioplasty are removal of the vagina, clitoral straightening and lengthening, urethral lengthening using available flaps and grafts, and creation of the scrotum with testicular prostheses implantation. The surgical goal is to achieve appearance of male genitalia, voiding in standing position, and full erogenous sensitivity. Modifications of the technique have developed due to recent advances in anatomy and new requests from transmen. Besides full metoidioplasty, other variants include metoidioplasty before, after or simultaneously with total phalloplasty. Each variant has its' own advantages, which must be discussed with the candidate preoperatively.

RESULTS

A total of 938 transmen with the mean age of 29 years underwent one-stage metoidioplasty between January 2004 and January 2022. In majority of cases (65%) metoidioplasty was performed as a final option, and the length of the neophallus ranged between 4 and 10 cm. Urethral complications occurred in 143 cases, dislocation and rejection of testicular implant in 55 and vaginal remnant in 92 cases. Voiding in standing position was reported in almost all cases (99%), and 12.5% of transmen requested phalloplasty after metoidioplasty.

CONCLUSION

Metoidioplasty is a safe, one-stage procedure with good esthetic and functional outcomes. It includes a wide spectrum of variants that can be offered to transmen as a part of genital reconstruction, with goal of achieving patients' satisfaction.
