If the skin is not loose enough, it may be necessary to cut off or put a dilator or something. Welcome to the plastic surgery clinic of Changzheng Hospital for consultation and treatment.
(Dr. Liu Antang from the Long March Hospital solemnly reminds me that because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
