Over or Under

One of the most common questions I hear during breast augmentation consultations is, "Dr. Ekstrom, should my implants go over or under the muscle?"
Some patients arrive having already consulted “Dr. Google or Dr. ChatGPT” and have decided exactly where they want their implants placed. While I encourage patients to educate themselves, the answer is not always that simple!
Traditionally, plastic surgeons have favored placing breast implants partially beneath the pectoralis major muscle, particularly in thinner patients. This technique, commonly called dual-plane placement, provides additional tissue coverage over the upper portion of the implant.
Below the Muscle — Advantages and Disadvantages
The additional muscle coverage can make implant edges less visible or palpable, particularly in women with very little natural breast tissue. Historically, studies have also associated submuscular placement with lower rates of capsular contracture, the formation of an abnormally tight scar capsule around an implant.
However, placing implants beneath the muscle involves lifting and releasing portions of the pectoralis muscle. This generally produces more postoperative discomfort and can prolong early recovery. Another potential disadvantage is animation deformity, where implants visibly move or change shape when the chest muscles contract.
Above the Muscle — Advantages and Disadvantages
With subglandular placement, implants rest behind the breast tissue but in front of the pectoral muscle. Surgery generally involves less muscle disruption, with less discomfort and often a quicker recovery. The implants also avoid animation deformity.
The disadvantages? In thin patients, implant edges may be more noticeable, and rippling or palpability may become an issue. Historically, subglandular placement has also been associated with higher capsular contracture rates.
What About Capsular Contracture Rates?
Older studies have reported contracture rates ranging from single digits to over 15%, depending on implant placement, surface, surgical technique, and length of follow-up. Some studies have found substantially higher rates above the muscle, but these figures cannot reliably predict an individual patient's outcome. Modern implants and improved surgical techniques have changed the equation, and there is no single percentage that applies to every patient.
A Changing Trend
Increasingly, surgeons are reconsidering above-muscle placement for appropriately selected patients. Another option, subfascial placement, positions the implant beneath the thin fascia covering the muscle without disturbing the muscle itself.
My philosophy? There is no universally superior implant pocket. Breast tissue thickness, skin quality, implant size, lifestyle, previous surgery, and individual expectations all matter.
After more than four decades in plastic surgery, I have learned that the best operation is not necessarily the newest or most fashionable technique. It is the one that best fits the individual patient!
