Why Do Nasolabial Folds Appear? Exploring the Anatomical Perspectives and the Role of Thread-Based Interventions.

The classification of nasolabial folds into three types, each with distinct causative factors and mechanisms, is explored. Age-related changes in facial skin and connective tissues are examined in detail, revealing variations across different facial regions due to variances in tissue firmness and thickness. The innovative 'Reverse Technique,' involving cog threads to enhance tissue traction and effectiveness in thread-lifting procedures, is introduced. Detailed technical guidelines, anatomical considerations, and safety measures are provided, emphasizing the importance of identifying optimal vectors and fixing points to achieve maximum lifting effects while minimizing potential risks, particularly those associated with vascular structures. Additionally, the 'Cross Technique using volumizing thread' is discussed, designed to smooth tissue boundaries and rejuvenate sagging areas. Facial anatomy, including the positioning of arteries and ligaments, is underscored as essential for ensuring the safety and efficacy of procedures. In conclusion, this review stands as a comprehensive guide for practitioners, offering insights into innovative thread-lifting methods and their applications in addressing nasolabial folds. The primary focus is on achieving optimal aesthetic results while prioritizing patient safety.

Chopstick technique versus cross technique in LESS hysterectomy (CCLEH study): a prospective randomized controlled trial.

BACKGROUND: The traditional cross technique can be used to complete most laparoendoscopic single-site surgery (LESS) procedures, but some relatively precise operations, such as vaginal stump suturing, are challenging. In practice, we have introduced a novel technique named the chopstick technique and applied it to more complex operations, such as cervical cancer operations, and found that it contributes to performing delicate surgery. The efficacy and safety of two different surgical techniques in LESS hysterectomy remain to be validated. METHODS: Patients who undergo total hysterectomy will be enrolled in this RCT. Stratified randomization will be performed according to uterine size (< 10 cm, 10-15cm, ≥ 15 cm). The participants will be divided into the chopstick technique group or cross technique group to undergo laparoendoscopic single-site total hysterectomy (LESS-TH), and then the perioperative and postoperative data, including the total operation time and other times, transfer rates, estimated blood loss, surgeon fatigue, intraoperative and postoperative complications (within 8 weeks after surgery), health-related quality of life (EQ-5D) scores, postoperative hospital stay, and hospitalization expenses, will be evaluated. The primary outcome is the operating time for total hysterectomy under LESS, and the other outcomes are secondary outcomes. DISCUSSION: It is expected that the efficacy of the two techniques in LESS, the chopstick technique vs. the cross technique, will be compared and accumulate safety data on the new techniques will be accumulated.

Técnica CROSS en cicatrices de acné / CROSS technique in acne scars

La cicatrización patológica es una complicación frecuente del acné que resulta del daño en la piel que se produce durante la curación de dicho proceso inflamatorio. Muchos pacientes desarrollarán cicatrices a pesar de un tratamiento oportuno y adecuado. A grandes rasgos se consideran dos tipos de cicatrización patológica: excesiva (cicatrices hipertróficas y queloides) e insuficiente (cicatrices atróficas). Estas últimas se ven en el 80-90% delos casos y se subclasifican en pica hielo, ondulada y en caja. Múltiples tratamientos se usan para eliminar las cicatrices del acné. A menudo, una combinación de varias técnicases necesaria para un tratamiento efectivo. La técnica CROSS es una modalidad terapéutica segura, eficaz y rentable en el tratamiento de las cicatrices pica hielo sin complicaciones significativas.

Pathological scarringis a common complication of acne that results from the skin damagethat occurs during the healing of this inflammatory process. Many patients develop scarringdespite a timely and appropriate treatment. Roughly two types of scarring are considered:excessive (hypertrophic scars and keloids) and insufficient (atrophic scars). The latter are seen in 80-90% of cases and are subclassified into ice pick, rolling and box car. Multiple treatments are used to remove acne scars. Often a combination of several techniquesis necessary for an effective treatment. The CROSS technique is a safe, effective andprofitable therapeutic modality for the treatment of ice pick scars without significant complications.
