Similar to general plastic surgery, transsexual surgery means a complete transformation of a person's entire social identity. In this society where there are still different standards and requirements for different sexes, many transgender people often fail in reality. Plastic surgery experts say that the surgical conditions for this completely changed identity are very strict: 1. The diagnosis of degeneration is correct. 2. The operation requires at least 5 years, and there is no repeated process. 3. Patients must live and work in public for at least 3 years with the gender of their choice. 4. Accept psychology before operation. Psychiatric treatment for not less than one year. 5. There must be hormone therapy for more than one year before operation. 6. There must be no marriage with its anatomical gender. 7. Psychiatrists must prove that their mental state is normal. 8. They must agree to postoperative follow-up. 9. They are all in their twenties. 10. No criminal, drug or alcohol abuse history. There are no obvious signs of male or female behavior. The patient and the surgeon agree on the operation. The local public security department made a judicial appraisal and recorded it, and agreed to change the gender 14 on the ID card after the operation. Close relatives have no objection. The patient is very clear about what may happen after the operation and is psychologically prepared. There are no surgical contraindications. Plastic surgery experts agree that: ① preoperative diagnosis should be clear; ② Strict selection of suitable surgical cases, combined with the clinical situation and the actual situation in China, make sure that the sex reconfirmation operation should be responsible for the patients.
