Objectives: The learning outcomes of the Echoguided Rectus Abdomini Fat Transfer presentation focus on enhancing surgical precision and patient safety in fat transfer procedures. Participants will learn how to effectively utilize ultrasound guidance to visualize anatomical structures, ensuring accurate fat placement while minimizing risks such as vascular injury and fat embolism. The session will also cover techniques for assessing fat viability and optimizing aesthetic outcomes. Attendees will gain valuable insights into the integration of echography into practice, improving overall results and safety.

Objectives: 1.To evaluate the comparative efficacy of ASC-exosome treatment improving postoperative scar.
2.To characterize time-dependent improvement using Vancouver Scar Scale, Observer and Patient Scar Assessment Scale
3.To investigate the temporal progression of therapeutic effects from early-phase improvements to sustained enhancements with ASC-exosome intervention.
4.To identify scar parameters unaffected by ASC-exosomes treatment to define its scope of therapeutic action.

Introduction: Exosomes have emerged as a promising therapeutic agent for various dermatological conditions, including acne, atopic dermatitis, and wound healing. This study aims to evaluate the efficacy of exosome in improving postoperative scar appearance and texture following revision rhinoplasty with costal cartilage, which results in a scar on the anterior chest.

Materials / method: The patients undergoing revision rhinoplasty with autologous costal cartilage, each presenting with a 3 cm incision scar of anterior chest, were enrolled in this study. This study was conducted by a postoperative scar mean 4.3 months after surgery, divided into medial and lateral halves. It involved 10 patients with exosomes (ASC-exosome) and control (Hyaluronic acid) applications, evaluated using the Vancouver Scar Scale (VSS) and the Patient and Observer Scar Assessment Scale (POSAS).

Results: Experimental group showed significant improvement in key parameters vs control group.OSAS reduced pigmentation, improved pliability of VSS by week 3 and OSAS by week 4. Relief improvement of OSAS by week 4 to 8. No differences in vascularity, height, or thickness. PSAS indicated significant improvements in scar color by week 4, stiffness by week 3, thickness by week 2. Irregularity showed significant difference at week 4 and 8. No difference in pain or itching.

Conclusion: The application of exosomes significantly enhances scar quality, particularly in terms of pigmentation, pliability and relief. These findings suggest that exosomes hold considerable potential as a therapeutic option for postoperative scar management.

Objectives: To understand the clinical applications and benefits of bipolar radiofrequency-assisted liposuction (RFAL) in both aesthetic and non-aesthetic indications, with a focus on achieving effective soft tissue contraction through minimally invasive techniques.

Introduction: Suction-assisted lipectomy was initially developed as a safe and minimally invasive method for removing subcutaneous fat for cosmetic purposes. In recent years, energy-based technologies have significantly enhanced the efficacy and outcomes of liposuction. Among these, radiofrequency (RF) has become a prominent tool for promoting non-excisional soft tissue contraction.

Materials / method: This presentation explores the use of bipolar RFAL technology, which delivers controlled radiofrequency energy to subcutaneous tissues through internal and external electrodes. The thermal effect induces adipose coagulation and dermal contraction, promoting skin tightening. Clinical applications in both body contouring and non-cosmetic indications will be discussed, drawing from real-case experiences and device-based treatment protocols.

Results: Bipolar RFAL has demonstrated consistent results in achieving improved body contouring outcomes with enhanced skin retraction. Additionally, non-cosmetic applications—such as treatment of gynecomastia and face overfilling syndrome —have shown promising results. The technique is reproducible, safe, and associated with high patient satisfaction and minimal downtime.

Conclusion: RFAL represents a significant advancement in energy-assisted liposuction, offering effective fat reduction and tissue tightening with minimal invasiveness. Its expanding role in both aesthetic and non-aesthetic procedures underscores its value as a versatile tool in modern plastic surgery.
