Background The loss of the umbilical vertical axis, causing a horizontal shape deformity after liposuction, is a current aesthetic issue. The use of energy devices, such as LASER and VASER, has been advocated as an option for improving skin retraction, but no data are available on the prevention of umbilical sagging. Objectives The authors sought to describe a technique for preventing umbilical deformities after medium definition liposuction employing suction-assisted liposuction. Methods Over a period of 31 months, 62 patients underwent medium definition liposuction with direct needle fixation of the umbilical stalk to prevent horizontal umbilical deformities. All patients underwent surgery performed by a single surgeon (G.B.). All patients underwent objective measurements of the umbilical shape before and after the procedure utilizing digital image measurements by Mirror Image software, version 6.0 (Fairfield, NJ). Statistical analysis was performed with IBM SPSS Statistics V26. The mean age of the patients was 28.8 years. The follow-up evaluation was performed 2 weeks and 9 months postoperatively. Results Over a period of 31 months, 60 patients (96.7%) who underwent abdominal etching liposuction showed maintenance of (n = 9, 14.5%) or improvements in the umbilical shape 9 months postoperatively (n = 51, 82.2%, P < 0.05). Two patients (3.2%) experienced worsening of the umbilical shape after surgery despite suture fixation. Conclusions Horizontal shape deformities of the umbilicus after liposuction can be improved by utilizing direct needle fixation of the umbilical stalk. The approach has been shown to be effective, safe, and reproducible for the prevention of umbilical sagging in selected patients. Level of Evidence: 4

RESUMO: Cordoma sacrococcígeo é uma neoplasia maligna rara que se origina de remanescentes da notocorda. A localização crítica, comportamento localmente agressivo, reconhecida resistência à radioterapia, significativa morbimortalidade cirúrgica e elevada taxa de recidiva tornam seu tratamento um desafio. Descrevemos um caso de cordoma sacrococcígeo gigante.Descritores: Cordoma; Região sacrococcígea; Radioterapia; Neoplasias; Diagnóstico.

Background: Not all patients who exercise regularly and follow a balanced diet will obtain a well-defined abdomen. Medium definition liposuction, together with the removal of abdominal skin, can recreate an adequate connection between the skin/subcutaneous components and the myo-aponeurotic layer, resulting in the perception of muscle definition. Methods: Over a period of 36 months, 351 patients underwent medium definition liposuction associated with abdominoplasty performed by a single surgeon (G.B.). All patients underwent an evaluation through digital photographs by two independent senior plastic surgeons, using an objective grading system for aesthetic outcomes proposed by Strasser, 12 months after the operation. Results: According to the Strasser Scale, 326 patients (93%) were considered to have good and excellent results. Twenty-two patients (6.2%) had moderate/mediocre results‚ and three patients (0.8%) had poor results. The overall complication rate was 4.8%. Conclusion: Medium definition liposuction associated with abdominoplasty has been shown to be effective, safe, and reproducible for most patients.
