The treatment of loose cervical opening is divided into loose cervical opening and loose internal opening, as follows: 1. The loose external opening does not require clinical intervention because it does not cause symptoms and has no effect on pregnancy, so it does not need to be treated. 2. This situation should be given high priority. After pregnancy, in order to avoid another miscarriage, the cervical cerclage can be done. After the cerclage is done, you can choose the appropriate time to remove the cerclage before the full term and then prepare for delivery.
