Cervical canal widening can be temporarily achieved by the insertion of dilators into the cervix. If the stenosis is caused by scar tissue, a laser treatment can be used to vaporize the scarring. [5] Finally, the surgical enlargement of the cervical canal can be performed by hysteroscopic shaving of the cervical tissue. [6]
The leading hypotheses for its mechanisms were that it could help keep the cervix closed similarly to the cerclage, as well as change the inclination of the cervical canal so that the pregnancy weight is not directly above the internal os.
In relation to the vagina, the part of the cervix that opens to the uterus is called the internal os and the opening of the cervix in the vagina is called the external os, [1] while between is the conduit of the cervix, commonly referred to as the cervical canal. The lower part of the cervix, known as the vaginal portion of the cervix (or ...
The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").
Prior to effacement, the cervix is like a long bottleneck, usually about four centimeters in length. Throughout pregnancy, the cervix is tightly closed and protected by a plug of mucus. Effacement is accompanied by cervical dilation. When the cervix effaces, the mucus plug is loosened and passes out of the vagina.

Effacement translates to how 'thin' the cervix is. The cervix is normally approximately three centimetres long, as it prepares for labour and labour continues the cervix will efface until it is 'fully effaced' (paper-thin). Cervical dilation: Closed 1–2 cm 3–4 cm 5+cm Dilation is a measure of how open the cervical os is.
A bimanual examination during early pregnancy will reveal that the uterus is enlarged, softened and globular; the external os may be dilated, but the internal os is typically closed. [24] The structures adjacent to the uterus will be assessed, along with the size and shape of the bony pelvis. [24]
