ABSTRACT
Background: The rejuvenation and restoration of a well-defined jawline contour are crucial for enhancing facial aesthetics in both men and women. Within the jawline aesthetic unit (mandibular angle), the masseter muscle plays a significant role, as it is responsible for mandibular masticatory movements. We propose a new approach using ultrasound-guided intramuscular fat transfer to enhance the mandibular angle and jawline. Methods: The multicenter study included 20 patients from three countries (Peru, Brazil, and Mexico). After fat harvesting, the ultrasound-guided masseteric fat transfer was performed with a 1.5-mm Viaro cannula from an incision beneath the ear lobule. The fat was then injected intramuscularly into the masseter at each side of the mandibular angle. Results: Masseter ultrasound-guided fat transfer was performed on 10 men and 10 women between 2021 and 2022. The patients had a mean age of 34.4â ±â 6.39 years and a mean body mass index of 22.39â ±â 2.59 kg per m2. The mean injected volume was 5.83 mL and 5.58 mL on the right and left sides, respectively. Muscle thickness increased in patients immediately postsurgery, but decreased after 1 month. The muscle remained significantly thicker on each side than the presurgery measurements in patients regardless of gender (both P < 0.0001). Conclusions: Ultrasound-guided intramuscular fat transfer is a safe and reproducible technique for enhancing the jawline contour at the mandibular angle. We believe that it could be a more durable solution than other procedures, although further evaluation of long-term results is necessary.
ABSTRACT
Background: Rib remodeling is a surgical technique for waist shaping in women and men. However, one of the main patient complaints is the scar. We aimed to describe a scarless, ultrasound-guided rib remodeling (RibXcar) technique that assessed the degree of angular variation of the fracture by ultrasound and the variation in waist measurement and patient satisfaction through a survey. Methods: The RibXcar technique was performed in 30 women aged 18-35 years in Peru, Colombia, and Mexico between October and December 2022 by three board-certified plastic surgeons trained in ultrasound and in this technique. The plastic surgeons measured costal angles before and immediately, 1 month, and 3 months after the surgery by ultrasound, as well as the waist in the same site and at these time points. Similarly, patient satisfaction was surveyed 3 months after the surgery, in which questions were asked about body aesthetics and the puncture site. Results: Ultrasound angular measurements before and immediately, 1 month, and 3 months after the surgical procedure were 168.00, 158.00, 160.00, and 160.43 degrees in the 10th rib, 170.50, 160.50, 152.50, and 163.50 degrees in the 11th rib, and 172.00, 162.00, 154.00, and 165.00 degrees in the 12th rib, respectively. The satisfaction survey showed that patients were satisfied with the aesthetic results of both the shape of the waist and the puncture site. Conclusions: RibXcar surgery maintains the angular variation over time. Similarly, waist measurements show a sustained reduction. Three months postoperatively, the patients were satisfied with the aesthetic results of the waist and the puncture site.
ABSTRACT
Las alteraciones electrolíticas son frecuentes en el paciente quemado, y en general se presentan enpacientes con quemaduras de mayor gravedad. Es poco conocida la frecuencia y magnitud de la hipomagnesemia, asicomo los factores de riesgo para presentarla en esta situación clínica. Se realizó un estudio retrospectivo observacional de revisión de casos, en 35 pacientes con quemaduras, manejados en el servicio de Cirugía Plástica Reconstructiva del Hospital Central Sur de PEMEX. Se determinó el comportamiento del magnesio sérico y se formaron dos grupos, un grupo de estudio que incluyó a 11 pacientes con quemaduras e hipomagnesemia, y un segundo grupo de 24 pacientes, con quemaduras y sin hipomagnesemia. Se determinaron los principales factores de riesgo relacionados con los episodios de hipomagnesemia. Se encontró que el paciente de mayor riesgo es aquel con quemaduras mayores de 40%de superficie corporal, de segundo y tercer grado, que se encuentra en el cuarto y el décimo día después de la quemadura, y que presenta hipocalemia, hipocalcemia o las dos y que además no ha recibido aporte por vía intravenosa este catión. La mejor manera de prevenirlo es identificar al paciente de alto riesgo o diagnosticar de manera oportuna para evitar mayores complicaciones.
Electrolyte abnormalities are common in the severely burned patient. There is little information with regard to the frequency and magnitude of hypomagnesemia, as well as on risk factors for this condition. We performed an observational, retrospective analysis of 35 burned patients treated at the Plastic and Reconstructive Surgery Service at the Hospital Central Sur PEMEX, Mexico City. We determined serum magnesium behavior and divided patients into two groups: the first included 11 patients with burns and hypomagnesemia, and the second, 24 patients with burns but without hypomagnesemia. Risk factor identification was performed. We found patient at riskwas the one with more than 40% of 2nd or 3rd degree total burned body area, in day 4 or 10 after the burn, and with hypokalemia, hypocalcemia, or both, and without intravenous (i.v.) supplementation of magnesium. The best way to prevent or avoid major complications is to identify the high-risk patient, or to diagnose earlier.

A 12-year-old patient case is reported, presented with a desmoid fibroma of the left pterygoid region, extended to the cortical and endosteal regions of the mandible, reconstructed immediately with a free peroneal flap, recovering with this both form and function. To date, 3 years from surgery, he has no complications. Evolution of this case and a brief review of the literature is reported. It is concluded that free peroneal graft for mandible reconstruction is safe and has excellent results, both aestethic and functional.

Objetivo: informe de un caso clínico y revisión de la literatura con relación al hamartoma de vías biliares (HVB). Antecedentes: el hamartoma de vías biliares es una lesión hepática rara descrita por primera vez en 1918 por Von Meyenburg, consistente en una deformación y desorganización de los conductos biliares, formando estructuras quísticas que varían de tamaño. Método: se trata de una mujer de 44 años de edad, asintomática. El ultrasonido mostró la presencia de lesiones diseminadas en el hígado que condicionaban irregularidades en el contorno. Posteriormente se realizó tomografía computada abdominal, donde se corroboró la presencia de lesiones hepáticas, múltiples e hipodensas de aspecto quístico, diseminadas en todo el órgano y una lesión en pelvis al nivel de útero en el infundíbulo izquierdo, interpretándose inicialmente como una probable tumoración maligna de ovario izquierdo con metástasis hepáticas. Se llevó a la paciente a laparotomía exploradora, con biopsias hepáticas, así como histerectomía radical. Resultados: el examen histológico transoperatorio reveló ser negativo a malignidad en todas las muestras. El resultado definitivo fue el de HVB y miomatosis uterina. Conclusiones: la presencia de HVB genera confusión en el diagnóstico y en el manejo de los pacientes que la presentan, por su apariencia como metástasis hepáticas.
