Clinically, cervical dilatation in women who are not pregnant can usually be treated with medications when the dilatation is mild. This can be done vaginally with a celiac pessary or vaginally with a compound sea buckthorn seed oil pessary. For patients with severe cervical dilatation, physical therapy or surgery is the best treatment. Patients should also be careful to avoid frequent sexual intercourse, abortion, frequent childbirth and genital hygiene in their daily life, otherwise the dilatation of the cervix may be aggravated. In case of dilated cervical canal during pregnancy, cervical cerclage can be performed in the middle of pregnancy to avoid mid-term miscarriage, late miscarriage and preterm delivery due to dilated cervix.
