Cosmetic surgery for hymen repair generally takes 15-30 minutes. Usually, 0. 1% bromogeramine solution or iodophor disinfectant is used to disinfect vulva and vaginal orifice, and 1% lidocaine is used for local infiltration anesthesia. Cut the damaged hymen neatly with ophthalmic scissors, and then carefully sew it with nylon thread or absorbable suture so that the hymen only passes through the hole of the little finger. Apply a little antibiotic ointment after operation, and dilute the vulva with 0. 1% bromogeramine solution or potassium permanganate solution every day after operation to prevent infection. It usually takes five days to remove the stitches. For those who have more sexual life, the operation is slightly complicated, which requires hymen reconstruction and labia minora mucosal flap to narrow the vaginal opening. No matter which method is used in the operation, the patients who have undergone the operation basically have no pain, and the hymen reconstructed by operation can generally recover in one to two months. However, it is forbidden to ride a bike or do exaggerated movements during the period to avoid tearing again. As for the time of marriage, it is suggested that two to three months after the operation is more appropriate.
