Muscle-Relaxant-Assisted Breast Augmentation
”Less Pain. Faster Recovery. Naturally Beautiful Results.”
In breast aesthetics today, women are seeking more than just size — they want comfort, safety, and natural results. One of the most advanced innovations in modern breast surgery, introduced by Dr. Piya at Nida Esth’ International, is the Muscle-Relaxant-Assisted Breast Augmentation — a refined technique designed to minimize pain, speed up recovery, and allow the implants to settle beautifully right from the start.
This innovative approach combines Dr. Piya’s surgical precision with the scientific use of muscle-relaxing medicine, creating a smoother, gentler healing process while maintaining the soft, natural look that defines his artistry.
Understanding the Concept When performing traditional breast augmentation, surgeons often encounter a natural response from the pectoralis major muscle — it tightens or contracts after surgery, especially when the implant is placed beneath the muscle (dual plane). This contraction can cause pain, pressure, or even make the implants feel firm in the early weeks of recovery.
To address this, Dr. Piya incorporates a precise pre-surgical technique: a carefully measured injection of muscle relaxant into the pectoral muscle before the implant is inserted.
This relaxes the muscle fibers temporarily, reducing the tension and resistance that usually occur post-operation. As a result, the implants settle faster, the breasts look more symmetrical sooner, and the recovery process becomes remarkably more comfortable.
Aesthetic Science Meets Comfort
This concept originated from aesthetic medicine, where muscle relaxants are commonly used to smooth wrinkles by relaxing facial muscles. Dr. Piya, known for his innovation and surgical artistry, applied this principle to breast surgery — not to change the look of the muscle, but to enhance the healing experience and final result.
By relaxing the chest muscles temporarily, the implants naturally find their optimal position, the surrounding tissues adapt smoothly, and the likelihood of capsular contracture (hardening caused by excessive scar tissue) is significantly reduced.
In essence, this approach brings together medical precision, comfort, and aesthetic balance — ensuring that the journey to a beautiful bust is as gentle as the result itself.
Key Benefits of the Technique
1. Minimal Pain and Discomfort
Because the chest muscles are relaxed before surgery, there is far less resistance when inserting the implant. Most patients report only mild tightness instead of pain during the first 48 hours — often requiring little to no strong pain medication.
2. Faster Recovery and Quicker “Settling”
The relaxed muscle allows the implant to adapt naturally to its position from day one. This means the breasts achieve their soft, natural shape much faster than with conventional methods.
3. Reduced Risk of Capsular Contracture
Capsular contracture occurs when scar tissue tightens around the implant. By lowering post-surgical tension in the muscle and surrounding tissue, this risk is minimized, resulting in a longer-lasting, natural outcome.
4. More Natural Movement
Because the implants settle harmoniously within the relaxed muscle pocket, breast movement looks and feels more natural — soft
when relaxed and supported when lifting or exercising.
5.Improved Symmetry and Shape
Muscle-relaxant precision ensures both sides of the chest respond equally, allowing Dr. Piya to achieve refined balance and
symmetrical curves even in patients with slight anatomical differences.
The Surgical Proces
1. Preparation and Planning
Each case begins with a 3D VECTRA® simulation to visualize the desired breast size and contour. The pre-operative muscle-relaxant dosage is calculated based on individual muscle density and implant type.
2. Muscle-Relaxant Administration
Before the incision, a small dose of the relaxant is injected into the pectoral muscle to gently release tension and prepare the area for implant insertion.
3. Implant Placement
The implant is then inserted using advanced techniques such as the Triple Plane Mini-Lifting or Subfascial approach — methods
that ensure perfect balance between natural movement and aesthetic projection.
4. Post-Surgery Recovery
Most patients experience minimal soreness. Soft laser therapy may be applied post-surgery at Nida Esth’ International to reduce
swelling, stimulate healing, and enhance comfort.
Ideal Candidates
Muscle-Relaxant-Assisted Breast Augmentation is ideal for:
• Women concerned about post-operative pain or tightness.
• Those with strong chest muscles (e.g., athletes, yoga practitioners, or frequent gym-goers) that tend to contract after surgery.
• Patients undergoing revision breast surgery who wish for a smoother, faster recovery.
• Anyone seeking a more natural, balanced result with shorter downtime.
This technique ensures that even those with highly active lifestyles can return to their daily routines quickly — usually within a few days to a week.
Safety and Precision at Every Step
At Nida Esth’ International, safety is the foundation of beauty. All procedures are performed in hospital-standard operating theatres under the care of board-certified anesthesiologists and plastic surgeons.
The muscle-relaxant medication used in this procedure is US FDA-approved and medically purified for surgical use. It does not affect the body’s overall muscle strength or long-term function. Once its effect subsides naturally within a few days, the muscles resume normal activity — leaving only the beautiful results behind.
What Dr. Piya Says
“Beauty should never come with unnecessary pain.
With the right technology and precision, we can create natural, elegant results while keeping the patient completely comfortable.”
For Dr. Piya, this technique is not just about reducing discomfort — it represents a new era of patient-centered aesthetic surgery, where
innovation is used not only to improve how breasts look but also how patients feel throughout their journey.
Combining Comfort and Artistry
When paired with the Triple Plane Mini-Lifting Technique, the Muscle-Relaxant-Assisted method becomes part of a comprehensive,
advanced program known as Dr. Piya’s Signature 3D Breast Augmentation. Together, these techniques offer:
• Closer cleavage with natural lift.
• Minimal pain and swelling.
• Smaller incision and rapid healing.
• Results that look and feel beautifully real.
This signature program has positioned Nida Esth’ International among Asia’s top medical centers for advanced breast surgery — recognized with international awards including “The Most Innovative Breast Augmentation Clinic of the Year in Asia Pacific 2024” by Global Health Asia Pacific and distinctions from HELLO! Magazine Thailand for outstanding innovation in beauty medicine.
The Future of Comfortable Beauty
The Muscle-Relaxant-Assisted Breast Augmentation redefines what modern breast surgery can be — not just about enhancement, but about comfort, confidence, and care. It ensures that every woman can enjoy a naturally beautiful silhouette without the fear of pain or prolonged recovery.
At Nida Esth’ International, beauty is not a one-size-fits-all formula — it is a personalized experience built upon expertise, technology, and compassion. And under the hands of Dr. Piya, even the journey toward perfection can be as smooth, refined, and effortless as the results themselves.
