aditus ad·i·tus (ād'ĭ-təs)
n. pl. aditus
An entrance to a cavity or channel.
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.
Granulations very quickly block the aditus and so separate the antrum and mastoid cavity from the tympanic cavity.
Care must be taken to introduce the gauze right down to the aditus and to pack the cavity evenly.
My idea was to give to the mind some notion of an approach to good things to come, and I proposed to call the place "aditus."
At the same time, however, the aditus should be exposed and the opening made funnel-shaped in order to allow of proper dressing.
The region of the aditus is now inspected under good illumination, using a head-light if necessary.
By working backwards the aditus is approached, the bone being removed carefully in small fragments.
