OPERATOR'S MANUAL
3) Guide the patient towards the unit so that he or she is
in front of the subnasal support and can grip the large
handles. The operator and the patient will face each
other. The patient must rest the base of his/her nose on
the subnasal support as shown in the figure.
4) Check the symmetry of the patient's head using the
sagittal vertical light beam as a guide. Check the proper
positioning of the Frankfurt plane using the upper
horizontal light beam, as shown in the previous figure.
If the examination requires it and if necessary, slightly
tilt the patient's head forward to help him/her open the
mouth as wide as possible.
5) Once the correct positioning has been reached, lock
the craniostat as explained in paragraph 5.4.2.
