When considering breast augmentation surgery, one of the most important decisions is choosing implant placement. This refers to where the implant is positioned in relation to the chest muscle. There are two primary techniques: placing the implant either over the pectoral muscle (subglandular) or under it (submuscular). The decision between under muscle vs over muscle breast implants can influence not only the surgical process but also the post-operative experience and long-term outcomes.

In this guide, we’ll explore the distinctions between subglandular vs submuscular implants, including potential benefits, limitations, and key factors to consider when making this decision. We’ll also outline recovery expectations and highlight important risks—all within the framework of current clinical standards.

What Is Breast Implant Placement?

Breast implant placement refers to how the implant is positioned in the chest:

• Subglandular placement means the implant sits directly behind the breast tissue but above the pectoral muscle.
• Submuscular placement involves positioning the implant beneath the pectoral muscle, partially or completely covered by it.

Each method is clinically appropriate depending on anatomical factors, personal goals, and surgical considerations. The placement is usually determined during a pre-operative consultation after a detailed assessment by a qualified medical professional.

Subglandular vs Submuscular Implants: Key Differences

Let’s take a closer look at the distinctions between subglandular vs submuscular implants.

Subglandular (Over-the-Muscle) Placement

In this approach, the implant is positioned above the chest muscle and beneath the natural breast tissue. This may be considered when there is sufficient existing breast tissue to cover the implant.

Considerations:

• May involve a shorter procedure duration.
• Less disruption to the pectoral muscle, which could reduce muscle-related discomfort in some cases.
• May not be ideal for individuals with thinner breast tissue, as there can be a higher chance of visible implant edges or rippling over time.

Submuscular (Under-the-Muscle) Placement

Here, the implant is placed beneath the pectoral muscle, either fully or partially. This method is often chosen when there is less natural breast tissue or when additional coverage over the implant is preferred.

Considerations:

• The chest muscle provides an added layer over the implant.
• Post-operative discomfort may be greater in the initial days due to muscle involvement.
• Recovery may take longer in some cases, with temporary movement restrictions.

It’s important to remember that under muscle vs over muscle breast implants are not universally better or worse; suitability depends on the individual’s anatomy, goals, and overall health.

Choosing Implant Placement: Factors to Consider

When choosing implant placement, your medical practitioner will assess a range of factors:

• Amount of existing breast tissue
• Chest wall anatomy and muscle structure
• Implant size and type
• Skin elasticity and thickness
• Desired outcomes and expectations

It’s essential to communicate openly during your consultation and ask questions about how each option might relate to your lifestyle, exercise habits, and post-operative recovery.

Understanding the Risks and Recovery

As with any surgical procedure, breast augmentation surgery involves risks. These include:

• Bleeding or haematoma
• Infection
• Capsular contracture (scar tissue around the implant)
• Implant rupture or leakage
• Changes in nipple or breast sensation
• Need for revision surgery

It is critical not to view the procedure as without risk. Results can vary significantly between individuals, and your surgeon will provide tailored advice based on your medical history.

Recovery Considerations

Recovery timelines vary depending on the chosen implant placement:

• Subglandular placement may be associated with less post-operative muscle soreness, though discomfort is still expected.
• Submuscular placement often involves more muscle-related discomfort, particularly in the first 7-10 days.
• Compression garments are usually recommended for 4-6 weeks.
• Most individuals require time off work, generally one to two weeks for desk-based roles.
• Upper-body activities such as lifting or strenuous exercise should be avoided for four to six weeks, as advised by your clinician.

Avoiding heavy lifting and following prescribed aftercare is vital to minimise complications and support appropriate healing.

Are Combined Techniques an Option?

In some cases, a dual-plane technique may be used. This approach combines elements of both subglandular and submuscular placement by partially placing the implant under the muscle and partially under breast tissue. This can be considered when more control over shape or coverage is required.

Again, this decision is made based on thorough anatomical assessment and consultation. It is not appropriate for everyone and should be discussed with your qualified medical practitioner. Sydney Plastic Surgeons Highlight 5 Key Breast Implant Characteristics for you to look at.

A Balanced Approach to Expectations

When considering breast implant placement, it’s important to take a balanced and informed view. Surgery is never without risks, and outcomes cannot be guaranteed. Individual factors like tissue quality, healing capacity, and natural anatomy all play a role in final results.

What works well for one person may not be suitable for another. This is why individualised consultation is so important, and why comparing before-and-after results or expecting specific changes can be misleading.

Final Thoughts

Exploring the difference between under muscle vs over muscle breast implants is a crucial part of planning for breast augmentation surgery. Understanding how breast implant placement affects appearance, recovery, and risks will help you have more informed discussions with your medical provider.

Always ensure you receive your care from a qualified, registered professional who provides clear, accurate information and supports your health every step of the way. Whether considering subglandular vs submuscular implants or another surgical approach, individual assessment and shared decision-making should guide the process.
