It has been established that the mastoid antrum begins forming in the sixth month of the intrauterine development. The anterior wall of the mastoid antrum of newborns is situated at the level of the posterior margin of the tympanic ring, the inferior wall is below the level of the upper margin of the tympanic ring. The thickness of the superior wall of the mastoid antrum of newborns is – 1,15±0,02 mm, the thickness of the lateral wall is 2,21±0,04 mm.
