Implicações da mamoplastia de aumento via transaxilar na pesquisa de linfonodo sentinela: revisão da literatura

BACKGROUND: The sentinel lymph node biopsy is the gold-standard technique for axillary staging in patients with early breast cancer, and its identification can avoid an unnecessary axillary lymph node dissection. The incidence of breast cancer is increasing each year; concomitantly, cosmetic transaxillary breast augmentation is gaining much more followers. OBJECTIVE: We conducted a literature review in order to evaluate if transaxillary breast augmentation can modify the lymphatic drainage and impair the identification of sentinel lymph node. METHODS: Review of the literature. CONCLUSION: The majority of the studies tend to exclude the hypothesis that the transaxillary breast augmentation could affect the identification of sentinel lymph node in the future.

Domestic three-dimensional scanner and printer in patients undergoing rhinoplasty

The principles for a successful rhinoplasty include preoperative consultation and planning, as well as a comprehensive clinical analysis and defining rhinoplasty goals. Three-dimensional domestic scanning and printing have recently become available. We sought to objectively describe this method as an intraoperative aid in patients’ anatomy. This method can be used trans-operatively to help surgeons compare the results of his or her technique, check adherence to the surgical plan, and improve his or her surgical decision-making. We found that the application of 3-dimensional printing had a positive effect on the treatment of patients with aesthetic nose disorders.

Prognosis of frontal region video surgery with a modified fixation technique

Introduction: Video endoscopy has become a procedure of choice for the treatment of eyebrow ptosis and forehead wrinkles. This minimally invasive technique has several advantages over traditional coronal incision. Several fixation methods are reported in the literature, with similar results. In this study, we describe direct needle fixation. Objective: To evaluate the prognosis of video endoscopic surgery using a direct needle technique. Method: Computerized photographic evaluations of 37 patients undergoing video endoscopy of the frontal region with needle direct fixation were conducted in two private hospitals in the city of Porto Alegre in Rio Grande do Sul, Brazil. Results: The mean eyebrow elevations were 5.7 and 4.4 mm in the lateral and middle third measurements. After a small dip in elevation in the first month after surgery, the repositioning of the eyebrow remained unchanged in subsequent measurements up to 24 months later. Conclusion: Direct needle fixation produced lasting, reliable, and reproducible results during the period in which measurements were made.

Otimização da marcação da incisão na dermolipectomia abdominal com emprego de molde padronizado

Preoperative marking of the incision in abdominoplasty plays a key role in the shape and position of the resulting scar. The undermining, traction, and resection of redundant tissue also influence these outcomes. After observation and statistical analysis of 36 abdomino plasty procedures, a preoperative marking template, which reproduces the incision shape that is considered the most suitable from an aesthetic point of view, was developed. The most suitable incision shape has 3 line segments: one central segment that is 11 cm ± 0.4 cm in length and 2 lateral segments that are 16.5 ± 2.3 cm in length at an angle of 155°. The template provides a quick, inexpensive, and consistent technique for reliably reproducing the suitable incision shape.
