Estimation of size changes occurring in infant umbilical hernia is difficult without a definite measuring technique. Accordingly, the principle of the industrial small hole gauge1 was employed in this study to follow more precisely the course of the hole defect in this condition.

The finger tip has been widely used as a hole gauge for this purpose and has the obvious advantage of handiness, but has the disadvantages of differing finger sizes among physicians plus the indefinite boundary limits of the finger tip itself.

Serial measurement of the abdominal wall defect with a set of makeshift hole gauges was found to be a satisfactory way of obtaining reasonably accurate hole diameters and of demonstrating to the parents the gradual closure that usually takes place (Fig. 1). At the same time, it is easy to explain why the skin bulge appears much the same, although the circular defect is closing,
