The patient bends her knees, places her heels together and lets
her knees drop to either side (this is known as the lithotomy

With your non-dominant hand, part the labia minora. Examine

the vulva and labia for abnormalities (e.g. erythema, ulceration,
warts and pigment changes).
Insert the speculum gently into the vagina; guide it towards

the base of the spine with the blades at approximately 45° to
the horizontal, adjusting the angle so the speculum passes with
minimal resistance.
Once the speculum is fully inserted warn the patient that they

will feel a stretching sensation and then slowly open the blades
to visualise the cervix including the SCJ. By ensuring that the
speculum is fully inserted you will open it at the vagina's widest
point and minimise discomfort.
Next minimise expansion so that although the cervix is seen,

In some women (particularly those on oral contraceptives or
in pregnancy) more columnar epithelium will be visible as a
reddened area, known as an ectropion (a physiological change;
erosion is an inaccurate term and describes ulceration, which
would signify pathological change) (Figure 23.4).
Make note of any irregularity, friable tissue or ulceration.
