[Projection of the sigmoid sinus onto the lateral surface of the mastoid portion of the temporal bone in young children].
In newborns and in children up to 3 years of age died of various causes (excluding otogenic diseases) 130 roentgenograms of the temporal bones were studied with a preliminary contrasting of the sigmoid sinus. A definite dependence in the position of the sigmoid sinus was noted: from the birth up to 3 years of age, from the posterior mastoid parts of the temporal bones the sigmoid sinus approaches its anterior parts. At an expanded form of pneumatization of the mastoid process in children (1-3 years of age) the sigmoid sinus in 82% of cases is projected in posterior parts of Chipaux's triangle, and at an organic form of pneumatization in 35% of cases it is outside Chipaux's triangle.
