Q1. What is the main objective and focus of this study?
Dr. Choi: Dr. Randquist, thank you for taking the time to speak with me. Could you briefly explain the core objectives and highlights of this study?
Dr. Randquist: Thank you, Dr. Choi. This research is a retrospective analysis from 2015 to 2020, involving 1,053 patients who underwent breast augmentation with Motiva SmoothSilk implants (both round and ergonomic designs). We sought to:
1. Compare the safety and efficacy of smooth implants versus textured implants.
2. Determine how these findings could be applied to optimized surgical techniques.
Moreover, we focused on how the rate of complications changed after refining surgical methods in 2018.
Q2. Why did you transition from textured to smooth implants?
Dr. Choi: Could you share the reasons for switching from textured implants to smoother options?
Dr. Randquist: Certainly. Textured surfaces were once believed to reduce capsular contracture by disrupting fibroblast alignment. However, subsequent studies revealed a link between textured implants and:
⢠Double capsule formation
⢠Chronic seroma
⢠Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL)
As a result, smooth implants gained attention as a safer alternative. In particular, Motiva’s SmoothSilk surface has been shown to reduce particle shedding, friction, and bacterial contamination, providing a more biocompatible environment.
Q3. What does the study reveal about the safety and effectiveness of Motiva implants?
Dr. Choi: Based on your findings, how would you rate the safety and effectiveness of Motiva implants?
Dr. Randquist: Motiva implants exhibit a very low complication rate. After surgical improvements in 2018, inferior displacement and lateral displacement decreased significantly:
⢠Lateral displacement: ~0.5%
⢠No reoperations for inferior displacement
Still, proper patient selection and tailored surgical techniques are crucial to achieve these outcomes.
Q4. How were your surgical techniques improved?
Dr. Choi: Could you elaborate on the modifications in your surgical approach and their effects?
Dr. Randquist: Prior to 2018, we selected implants without thorough assessment of the patient’s tissue quality or skin condition. After 2018, we:
1. Carefully matched the implant type to the patient’s anatomical and tissue characteristics.
2. Adopted a conservative approach to Cooper’s ligament dissection and pocket design.
The result was enhanced pocket stability, significantly reducing inferior and lateral shifts:
⢠Lateral displacement dropped to 0.5%.
⢠Inferior displacement: 0 reoperations.
Q5. You emphasize “patient planning.” How is this applied in practice?
Dr. Choi: The study highlights the importance of “patient planning.” Could you clarify what that entails?
Dr. Randquist: “Patient planning” involves assessing each patient’s breast anatomy, skin quality, and soft-tissue elasticity to determine the optimal implant choice and surgical technique. For patients with thin or less elastic skin, the risk of implant displacement is higher, so we often recommend fat grafting or, in certain cases, a textured implant if necessary. Essentially, there’s no one-size-fits-all approach; each patient needs a customized surgical plan.
Q6. How have implant size preferences and placement changed?
Dr. Choi: Have there been any shifts in the preferred implant size or placement methods?
Dr. Randquist: In the early phases of our research, larger implants (300cc+) were more common. As our surgical techniques evolved, we increasingly used 200–299cc implants placed in either the subfascial or submuscular plane. When needed, we supplement the volume with fat grafting. Consequently, the use of implants larger than 300cc has declined notably.
Q7. What specific techniques do you use to stabilize implant position?
Dr. Choi: Which methods do you use to keep implant positioning stable during and after surgery?
Dr. Randquist: We utilize two main strategies:
1. Avoid over-dissection of the pocket, preserving Cooper’s ligaments and the inframammary fold (IMF).
2. Perform multilayer suturing (often called the “lucky 8 stitches”) to secure the IMF to the chest wall. This helps maintain the implant position long after surgery.
Q8. What is the most crucial conclusion from this study?
Dr. Choi: Finally, what is the study’s most significant conclusion?
Dr. Randquist: The key takeaway is that Motiva implants are safe and effective for breast augmentation. However, maximizing their benefits requires carefully aligning patient tissue characteristics with implant features. In practice, that means:
⢠Avoid unnecessary cutting of Cooper’s ligaments.
⢠Reinforce and stabilize the IMF.
⢠Select an implant size and shape appropriate for each patient.
These steps collectively help minimize complications and enhance patient satisfaction.
