In ideal stoma characteristics, where should the ostomy opening be located?

• A. In the center
• B. Off to one side
• C. Near a scar line
• D. Near the umbilicus

Answer: (A)

Centering the ostomy opening over the stoma is essential because it ensures the skin barrier sits evenly around the stoma, creating a uniform seal on healthy skin. When the opening is centered, the flange contact surrounds the stoma equally, reducing gaps where stool could escape and minimizing irritation to peristomal skin. An off-center opening can create uneven edges, increasing the risk of leaks and skin breakdown. Placing the opening near a scar line or in a contour like near the umbilicus can lead to irregular fit due to scar tissue or skin folds, making a reliable seal harder. For a stable, protective fit, locate the opening so it sits in the center of the stoma site.
