A flat ostomy appliance has a flat baseplate that sits directly against the skin and is used when the stoma protrudes well from the abdomen. A convex ostomy appliance has a slightly rounded or dome-shaped baseplate that applies gentle pressure around the stoma, helping it protrude more and is used for flush or retracted stomas to improve the seal and prevent leaks.
