Abstract
Based on the dissections of 24 bones of 12 macaques (Macaca mulatta),
a systematic anatomical description was made and measurements of the chosen
size parameters of the temporal bone as well as the skull were taken.
Although there is a small mastoid process, the general arrangement of the
macaque’s temporal bone structures is very close to that which is observed in
humans. The main differences are a different model of pneumatisation and
the presence of subarcuate fossa, which possesses considerable dimensions.
The main air space in the middle ear is the mesotympanum, but there are also
additional air cells: the epitympanic recess containing the head of malleus
and body of incus, the mastoid cavity, and several air spaces on the floor of
the tympanic cavity. The vicinity of the carotid canal is also very well pneumatised
and the walls of the canal are very thin. The semicircular canals are
relatively small, very regular in shape, and characterized by almost the same
dimensions. The bony walls of the labyrinth are relatively thin.
