The glans cannot be fully exposed after circumcision, which means that too little foreskin was removed during the operation and too much foreskin was retained. If most of the foreskin can be exposed, no treatment is needed. If most of the foreskin can not be exposed, a second operation is needed, and patients with hidden penis can undergo corrective surgery at a later stage. 1. Most of them can be exposed: If only a small part of them cannot be exposed, there is no need for another surgery, but you still need to pay attention to the genital hygiene, especially at the coronary groove. 2. Most of those who can not be exposed: for most of the glans can not be exposed, it means that there is still the case of circumcision, and if you do not pay attention to hygiene in the late stage, it may also lead to the emergence of glansitis, phimosis, etc., so you can give circumcision again on an elective basis. 3. Hidden penis: hidden penis can not fully expose the glans, if necessary, can be given on an optional basis to correct the penis surgery, such as penile release surgery. It is recommended that the patient should consult a doctor in time and be treated by a professional physician for the condition.
