Historical Examples
The end of the tubing is pushed into the entrance of the aditus.
As the aditus is approached, the strokes of the chisel must be very gentle.
Care must be taken to introduce the gauze right down to the aditus and to pack the cavity evenly.
Granulations very quickly block the aditus and so separate the antrum and mastoid cavity from the tympanic cavity.
At the same time, however, the aditus should be exposed and the opening made funnel-shaped in order to allow of proper dressing.
