Yes, skin flap repair requires hospitalization, but it is not strictly necessary. If you insist on not being hospitalized or have a little friendship with the doctor, you can not sign the outpatient case. Now it is more suitable for 5 months. It can't be done at first because if too much subcutaneous tissue is removed, it will easily lead to poor blood supply and necrosis of the flap. Now it has basically recovered well and can be repaired. As for the degree of wear resistance, of course, the abdominal pedicle flap has poor wear resistance and unsatisfactory appearance, especially rough work, but it will be better after a long time, and the thenar flap will be much better when it is relatively old, both in appearance and wear resistance. As for hair, yes, if you take more skin flap hair from your stomach, it will decrease after grinding for a long time.
