Introduction

One of the most common complications for ostomy patients is a retracted stoma, where the stoma sits below the skin surface. This can cause leaks, skin irritation, pouch lift, and discomfort

That is where deep convex baseplates are helpful. With a curved, out-turned design, these baseplates softly press against the skin to assist the stoma to protrude into the pouch, lessening leaks and enhancing wear time. Among the top solutions are Coloplast deep convex baseplates, which come in several sizes (40 mm, 50 mm, 60 mm, and 70 mm) to fit individual requirements.

In this blog, we’ll explore why deep convexity is a game-changer for people with retracted stomas, focusing specifically on SenSura Mio Deep Convex Baseplates and Alterna Deep Convex Baseplates. We’ll compare their features, benefits, and sizing options, while also sharing practical tips for choosing the best baseplate for retracted stomas.

The Need for Deep Convex Baseplates

For individuals with a recessed or retracted stoma, getting a consistent pouching system seems like an impossible task. Deep convexity is the answer. A deep convex baseplate has an exaggerated outward flare with a smooth yet firm compression on the skin around the stoma. The rounded surface of the baseplate causes the stoma to protrude into the pouch, providing a more secure seal and a lower likelihood of leaks.

Deep convexity is especially beneficial for individuals with:

• Retracted or recessed stomas that sit below skin level.
• Abdominal folds, dips, or creases that interfere with a flat seal.
• Uneven peristomal surfaces where traditional flat or light convex options don’t provide adequate support.

By enhancing the seal, Coloplast deep convex baseplates greatly minimize the risk of leakage, save sensitive peristomal skin from irritation, and increase general comfort. Not only does this prevent pouch lift and skin damage, but it also increases confidence in daily life.

Coloplast offers a complete range of convex ostomy baseplate sizes—40 mm, 50 mm, 60 mm, and 70 mm. We have baseplates to fit every pouching system and body type. Choosing the correct deep convex ostomy baseplate size can make the crucial difference in effectively managing a retracted stoma.

SenSura Mio Deep Convex Baseplates

Coloplast SenSura Mio Deep Convex Baseplate is one of the most sophisticated solutions out there for patients with deep or retracted stomas. As it is made as a two-piece system, it is both secure and flexible, allowing ostomates to be confident in their daily habits.

Available Sizes: 50 mm, 60 mm, 70 mm

Key Features:

• Adaptive Deep Convex Design: The SenSura Mio convex baseplate is designed to offer gentle yet firm pressure around the stoma, encouraging it to protrude into the pouch. It's particularly beneficial for stomas that are below skin level or are embedded in folds of skin.
• Integrated Flex Lines: Notably, the design features built-in flex lines. These are small, incorporated ridges that enable the baseplate to curve and flex naturally with the movement of the body. This provides comfort and security without sacrificing seal.
• BodyFit (Elastic Adhesive) Technology: Unlike standard adhesives, SenSura Mio’s elastic adhesive (backed by BodyFit Technology) also stretches and flexes with the skin. This minimizes edge lifting, ensures long-lasting skin comfort, and prevents leakage by keeping a tight seal even when moving during the day.
• Audible "Click" Coupling System: To give reassurance at the time of application, the two-piece SenSura Mio baseplate has a coupling system that clicks audibly as the pouch is firmly locked into position. The easy confirmation makes users feel secure in knowing their pouch is properly fastened.

The SenSura Mio deep convex baseplate thus provides a modern and secure solution for ostomates.

Alterna Deep Convex Baseplates

The Alterna Deep Convex Baseplate is another trusted solution from Coloplast, designed specifically to help people with retracted or difficult-to-manage stomas. Like the SenSura Mio, it is a two-piece baseplate system, offering both security and flexibility.

Available Sizes: 40 mm, 50 mm, and 60 mm.

Key Features:

• Spiral Adhesive Technology: Alterna makes use of Coloplast's special spiral adhesive, which blends skin-friendly materials with powerful adhesion. In addition to keeping the baseplate securely in place, this dual action also shields the sensitive peristomal skin from irritation.
• Mechanical Coupling with Audible Click: The Alterna baseplate has a secure coupling system that, when the pouch locks into position, emits an audible click. This guarantees that users can rest easy knowing the bag is securely fastened.
• Deep Convex Design: The Alterna deep convex baseplate offers mild, uniform pressure around the stoma thanks to its noticeable outward curve. Stomas that sit in deep skin folds or below skin level benefit greatly from this additional support, which prolongs wear time and helps stop leaks.

With its combination of reliable adhesion, secure coupling, and effective convex design, the Alterna deep convex baseplate offers a practical and proven option for those seeking better ostomy solutions for a retracted stoma.

Side-by-Side Comparison: SenSura Mio vs. Alterna Deep Convex Baseplates

Tips for Choosing the Right Deep Convex Baseplate for You

Here are some expert tips to choose the correct deep convex baseplates:

• Measure accurately: Double-check coupling diameter (40–70 mm), hole diameter, and stoma level against skin.
• Test initially: Test short wear periods to determine how the baseplate accommodates and feels.
• Fit your lifestyle: For active users, flexible alternatives such as SenSura Mio fit the bill, while Alterna provides increased adhesion for excessive folds.
• Consider skin sensitivity: Select adhesives that shield sensitive skin.
• Consult experts: If the stoma alters position or form, consult a stoma nurse.

Selecting the ideal deep convex baseplate guarantees everyday comfort, security, and peace of mind.

Use & Care Best Practices

• Use properly: Position the baseplate centrally over the stoma so the convex curve hugs the skin. Smooth edges to lock in seal.
• Replace frequently: Usually every 2–3 days for large convex baseplates, or earlier if you feel uncomfortable or experience leakage.
• Clean with care: Clean the area around the stoma using a soft cloth and lukewarm water. You can also use Comfeel Cleanser Wipes for the same. Never use harsh soaps or oils, which can disrupt adhesion.
• Look for warning signs: Redness, irritation, leakage, or skin breakdown could be a sign of a poor seal. If this happens, experiment with a different convex ostomy baseplate size or see a stoma nurse.

Using your Ostomy Baseplate correctly and following care best practices helps increase wear time, protect the skin, and keep your pouching system secure.
