RESUMO
OBJECTIVES: To describe characteristics of women with aesthetically ideal buttocks and differentiate them from women with normal buttocks. METHODS: Case-control study comparing anatomy of women with ideal buttocks (buttocks models) to women with normal buttocks using magnetic resonance images, anthropometric measurements and photography. RESULTS: Comparing to normal women, buttocks models have a narrower waist, narrower iliac crest, wider C point, wider hips and bigger and thicker gluteus maximus muscle (GMM). A bigger GMM adds more projection to the C point, point of maximum projection in the lateral view is 2.7 cm higher than the pubic bone. The amount of subcutaneous fat was equal in models and controls. CONCLUSIONS: Our study provides new knowledge regarding the tridimensional aspects of the beauty of the buttocks area. A beautiful buttock is a conjunction of adequate bony shape, muscle development, subcutaneous fat layer, and tight skin. Comparing to normal women, buttocks models have a narrower waist, narrower iliac crest, wider C point, wider hips and bigger and thicker Gluteus Maximus Muscle. Accurate understanding of the aesthetic goals in a given patient can guide surgical technique. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Purpose: The purpose of this study is to evaluate surgical outcomes of facial fractures after the introduction of intraoperative radiology. Methods: An historic cohort of patients without intraoperative fluoroscopy (IOF) was compared with a prospective cohort of patients with IOF. Main outcomes were postoperative complications and reoperation rate. Results: There were 51 in the non-IOF group and 49 in the IOF group. In the group with IOF 10 patients required intraoperative revisions (20.46%). Overall postoperative complication rate was higher in the non-IOF group (25.49% vs. 6.12%) due to the significantly higher bone-related complication rate (15.69% vs. 2.04%). Reoperation rate was also higher in the non-IOF group (11.76% vs. 0%). Conclusion: This study demonstrates that IOF reduces bone-related complication and reoperation rate by allowing correction of surgical errors immediately during surgery.

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emergent disease that threatens patients with texturized breast implants. Major concerns about the safety of these implants are leading to global changes to restrict the utilization of this product. The principal alternative is to perform breast augmentation utilizing smooth implants, given the lack of association with BIA-ALCL. The implications and costs of this intervention are unknown. OBJECTIVES: The authors of this study determined the cost-effectiveness of smooth implants compared with texturized implants for breast augmentation surgery. METHODS: A tree decision model was utilized to analyze the cost-effectiveness. Model input parameters were derived from published sources. The capsular contracture (CC) rate was calculated from a meta-analysis. Effectiveness measures were life years, avoided BIA-ALCL, avoided deaths, and avoided reoperations. A sensitivity analysis was performed to test the robustness of the model. RESULTS: For avoided BIA-ALCL, the incremental cost was $18,562,003 for smooth implants over texturized implants. The incremental cost-effectiveness ratio was negative for life years, and avoided death and avoided reoperations were negative. The sensitivity analysis revealed that to avoid 1 case of BIA-ALCL, the utilization of smooth implants would be cost-effective for a risk of developing BIA-ALCL equal to or greater than 1:196, and there is a probability of CC with smooth implants equal to or less than 0.096. CONCLUSIONS: The utilization of smooth implants to prevent BIA-ALCL is not cost-effective. Banning texturized implants to prevent BIA-ALCL may involve additional consequences, which should be considered in light of higher CC rates and more reoperations associated with smooth implants than with texturized implants.

BACKGROUND: The superficial circumflex iliac artery perforator flap (SCIP) is a thin, pliable, and versatile flap used mainly for extremities and head and neck reconstruction. Different planning methods have been described, but these are not yet standardized like in other flaps. The aim of this study is to present a fast, effective, and reliable method for SCIP flap planning using computed tomography angiography (CTA). PATIENTS AND METHODS: Between October 2017 and September 2018, CTA was performed on 40 patients. Preoperative planning of SCIP flaps based on the medial branch was performed analyzing CTA images. The perforating sites of the medial branch on the deep (point D) and superficial fascia (point S) were identified. Distances to those points, from the center of the umbilicus in the "y-axis" and the midline perpendicularly in the "x-axis," were measured. These measurements were transferred to the patient's skin as a guide for dissection. RESULTS: Eighty areas were studied identifying points D and S in CTA. Forty-three SCIP flaps were performed using this planning method. In 100% of the flaps, points D and S matched perfectly with handheld Doppler and surgical findings. CONCLUSION: Points D and S method for medial branch based SCIP planning with CTA is an easy to learn, efficient, fast, and reliable technique for preoperative planning, allowing a safe and predictable elevation of the flap.

INTRODUCTION: Perioperative microsurgical planning increases the likelihood of successful results. Augmented reality (AR) is the addition of artificial information to allow the user to perform tasks more efficiently. The aim of our study is to report the use of AR for microsurgical planning with a smartphone (ARM-PS) as a dissection route map. PATIENTS AND METHODS: AR was used for superficial circumflex iliac artery perforator (SCIP) flap planning. Three-dimensional (3D) reconstruction images of the inguinal and lower abdomen vascular anatomy were obtained by computed tomography angiography. These 3D images were imported to a smartphone and an AR app was used to superimpose them with the camera. The drawings performed with ARM-PS were correlated with handheld Doppler and intraoperative findings. RESULTS: The correlation of ARM-PS drawings with handheld Doppler results was 100% for superficial inferior epigastric artery (SIEA) and superficial and deep branches of SCIP in 60 inguinal areas studied. Intraoperative findings matched perfectly in all 30 cases with ARM-PS drawings for the location of the mentioned vessels and lymph nodes. Flap harvest time decreased in 20% compared with our traditional timing. CONCLUSIONS: ARM-PS is an easy, noninvasive, and accurate method that provides a dissection route map, thereby standardizing flap harvesting, and shows a perfect correlation with intraoperative findings. It reduces operating time and may improve operative results, thus decreasing donor site morbidity.

BACKGROUND: Body contouring surgery (BCS) is becoming increasing popular for aesthetic and reconstructive purposes, particularly among patients with massive weight loss (MWL). However, data on quality of life (QoL) following the surgery are limited, especially long-term QoL. OBJECTIVES: The authors evaluated the effect of BCS on QoL and the durability of this effect over time. METHODS: QoL was measured with the Body-QoL® instrument at 3 time points among consecutively treated patients: the day before BCS, 1 to 9 months postoperatively (short term), and 1 to 2.7 years postoperatively (long term). Total Body-QoL scores were compiled, as were scores for the instrument's main domains: body satisfaction, sex life, self-esteem and social performance, and physical symptoms. Scores were examined for the entire study population and separately for the cosmetic and MWL cohorts. RESULTS: Fifty-seven of the 112 patients participated in the short-term assessment and 84 in the long-term assessment. Total Body-QoL scores increased significantly (P < 0.0001), from 44.0 ± 14.1 preoperatively to 85.5 ± 17.5 short-term postoperatively and to 84.4 ± 12.7 long-term postoperatively. Scores for the 2 postoperative assessments did not differ significantly. Similar results were observed for scores on each separate domain. Although preoperative scores were lower for the MWL cohort than the cosmetic cohort (33.9 ± 15.6 vs 46.1 ± 12.8; P = 0.0002), they improved substantially after BCS, approaching scores for the cosmetic cohort. CONCLUSIONS: QoL increases significantly after BCS. This favorable outcome remained stable throughout long-term follow-up and was true for the cosmetic and MWL cohorts.

Resumen Introducción: Las lesiones complejas de la cara plantar del pie son de difícil manejo desde el punto de vista reconstructivo. En la literatura el tratamiento de elección es la cobertura mediante colgajos libres. Nuestro objetivo es presentar el caso de un paciente con una lesión plantar compleja, exitosamente resuelta con el uso de matriz de regeneración dérmica (Integra®) e injerto dermoepidérmico. Caso clínico: Hombre de 35 años, que sufre quemadura eléctrica de alta tensión con lesión compleja plantar bilateral. Se manejó con escarectomías sucesivas hasta delimitar el daño tisular, y posterior cobertura con Integra® e injerto con resultado estético y funcional óptimo. Discusión: Aunque los colgajos libres son la elección en el tratamiento de esta zona anatómica, infrecuentemente son la única alternativa de reconstrucción en el paciente quemado. No hay mayor evidencia en la literatura en el uso de matrices dérmicas para la cobertura de este tipo de lesiones. Conclusión: Los autores consideran que el manejo de lesiones plantares complejas mediante el uso de matrices de regeneración dérmica es una alternativa válida a considerar en situaciones en que, por diversos motivos, no se puede ofrecer un colgajo libre.
Abstract Introduction: Complex wounds of the plantar aspect of the foot are difficult to manage in the reconstructive point of view. The standard of treatment is covering the defect with free flaps. Our goal is to present the case of a patient successfully treated with the use of matrix dermal regenaration Integra® and dermoepidermal graft for a complex plantar lesion. Clinical case: Thirty-five year old man, who suffers from high voltage electrical burn with bilateral plantar complex injury. It was handled with successive escharectomies to delimit tissue damage and subsequent coverage with Integra® and grafting with optimal aesthetic and functional results. Discussion: Although free flaps are the choice in the treatment of this anatomical area, they are infrequently the only reconstructive option in burned patients. There is no greater evidence in the literature on the use of dermal matrices to cover such injuries. Conclusion: The authors believe that the management of complex footpad lesions using dermal regeneration matrices are a valid alternative to consider in situations where for various reasons, free flaps can't be offered.

Introducción: La calidad de vida es uno de los resultados en cirugía de contorno corporal más importantes. La evidencia sobre la calidad de vida de estos pacientes a largo plazo es escasa. El objetivo de este estudio fue determinar si la calidad de vida obtenida en el postoperatorio temprano posterior a la cirugía de contorno corporal se mantiene a largo plazo. Métodos: Se diseñó un estudio de cohorte prospectiva compuesta por pacientes postoperados de cirugía de contorno corporal con más de un año de seguimiento. La calidad de vida fue medida con el instrumento Body-Qol®. Se compararon los puntajes preoperatorios, postoperatorios tempranos y postoperatorios tardíos. Se realizó el análisis estadístico con las pruebas de Kruskal-Wallis y Kolmogorov-Smirnov. Resultados: La cohorte se compuso de 112 pacientes con un seguimiento a largo plazo del 75%. En toda la cohorte la calidad de vida mejoró entre el preoperatorio (43,9 ± 14,1 puntos) y ambas mediciones postoperatorias (85,2 ± 16,8 postoperatorio temprano y 83,6 ± 13,5 postoperatorio tardío), siendo estadísticamente significativo (p < 0,0001). Entre el postoperatorio temprano y tardío no existió diferencia (p = 0,112). El análisis por dominios demostró la misma tendencia. Los pacientes con pérdida masiva de peso tuvieron puntajes preoperatorios menores, pero igualaron a la población estética en ambas mediciones postoperatorias. Conclusiones: La calidad de vida mejora significativamente posterior a la cirugía de contorno corporal de forma temprana, y esta mejoría es estable en el tiempo. Esto se observa tanto en los pacientes estéticos como en los posteriores a la pérdida masiva de peso.
Introduction: One of the most important outcomes in patients undergoing body-contouring surgery is quality of life. Data on long-term quality of life is deficient. The main purpose of this study is to determine if short-term QoL after body contouring surgery maintains in the long-term follow up. Methods: A cohort study was designed; patients with at least one-year follow-up from the surgery were included. Quality of life was measured with the Body-Qol© instrument. All patients answered the preoperative Body-Qol© and at least one measurement after one year of follow-up from body contouring surgery. The preoperative scores, short-term scores and long-term follow-up scores were compared. The statistical analysis was made with Kruskal-Wallis y Kolmogorov-Smirnov tests. Results: The cohort was integrated by 112 patients; the long-term follow-up was of 75%. Quality of life improved between the preoperative measure (43.9 ± 14.1 points) and both short-term and long-term measures (85.2 ± 16.8 early postoperative y 83.6 ± 13.5 late postoperative), which was statistically significant (P< .0001). There was no difference between the short-term and long-term measures (P = .112). The domain analysis demonstrated the same tendency. Massive weight loss patients had lower preoperative scores but improved more after BCS, reaching almost cosmetic values. Conclusions: Quality of life improves soon after surgery and is stable over time. This was observed for both massive weight loss and cosmetic patients.
