What does depth of balloons mean?
The areas of the skull that I have found important for treatment can be generalized as anterior (shallow), intermediate or posterior (deep). This is important for the choice of the shape of the inflating balloons. To reach a deeper joint in the head, thicker balloons (greater gauge) are required. Shallower depths are reached with thinner balloons. These variations will make the treatment feel different to the patient at the moment of inflation, but the changes felt after inflation tends not to differ.
