A moderately protruding stoma protrudes how many centimeters?

• A. 0-0.5 cm
• B. >3 cm
• C. No protrusion
• D. 1-3 cm

Answer: (D)

In ostomy care, how far the stoma projects from the skin guides the type of appliance and how it will seal. A moderately protruding stoma typically sits about 1 to 3 cm above the skin. This range provides enough stoma exposure to help the barrier seal well and protect the surrounding skin from contact with output, without being so far out that it creates fitting challenges.

If a stoma only protrudes 0 to 0.5 cm, it’s considered flat or minimally protruding and can be harder to seal with a standard pouching system, sometimes requiring a convex barrier or adjustments for a better fit. If it protrudes more than 3 cm, it’s a high protrusion, which may necessitate different appliance options and careful assessment for comfort and skin protection. Therefore, 1–3 cm is the appropriate range for a moderately protruding stoma.
