Facial paralysis, etiology and surgical treatment in a tertiary care center in plastic and reconstructive surgery in Mexico.

BACKGROUND: Facial paralysis is a frequent disabling entity that causes a negative impact on the cosmetic, functional, social, psychological and economic aspects of the patient. Surgical treatment aims to restore the patient to her previous life with the fewest possible sequelae. OBJECTIVE: Describe the experience of surgical management and propose a treatment algorithm. METHOD: A retrospective study was carried out from 2017 to 2019 of the records of patients with facial nerve involvement. The variables were age, sex, etiology, affected side and procedures performed. RESULTS: 108 patients were obtained. The most frequent cause was development facial paralysis (41,8%), followed by resection of intracranial tumors (29%). A total of 225 procedures were performed, average per patient of 2.7. The most performed dynamic procedure was the gracilis-free flap (59%). The most frequent static procedures were the placement of a gold weight (24%) and the recreation of the nasogenian sulcus (13%). CONCLUSIONS: The surgical treatment algorithm will depend on the evolution time, etiology, donor nerves and state of the facial musculature. The gracilis-free flap continues to be the gold standard procedure in facial paralysis reconstruction. Static procedures are additionally required to achieve a satisfactory aesthetic and functional result.

Master Series Microsurgery for Residents: Results from a Comprehensive Survey of a Multitudinous Online Course during COVID-19 Pandemic.

BACKGROUND: Since COVID-19 emerged, it has significantly affected medical education. Surgical training has been blocked and the learning curve flattened. However, COVID-19 led to the outbreak of multitudinous online courses. Master series: microsurgery for residents (MSMR) has been the most extensive and accessible online nonfee course transmitted so far regarding reconstructive microsurgery. The primary aim of this study was to assess the impact of the MSMR in the surgical community as an international educational tool during pandemic confinement. METHODS: A retrospective, observational, analytic, and transversal study was designed. An 11-item survey was sent to all the 1,513 attendees who completed at least 60% of course attendance during 2 days. Descriptive and analytic statistics were performed. The impact was measured by considering answers to questions 6 to 9 and 11 (course usefulness, microsurgery interest increase, desire to pursue a microsurgical career, attendance to in-person conferences, and overall score, respectively). RESULTS: A total of 1,111 (73.4%) of eligible subjects were included. In total, 55.8% were plastic surgery residents. After the course, 98.9% would pursue a career in reconstructive microsurgery, and 45% would stop attending in-person conferences. The overall score of the event was 9.06 ± 0.9 (from 0 to 10) regardless of the current training status. CONCLUSION: The MSMR was a high impact course and has established a paradigm shift that will lead to an evolution in plastic surgery learning.

Power-Assisted Liposculpture in Male Patients: A Spectrum of Definitions.

BACKGROUND: Liposculpture procedures have gained popularity over the last 2 decades with the evolution of surgeons' skills and technological advancement. According to the 2018 The Aesthetic Society report, liposuction is the second-most popular aesthetic procedure in the United States. OBJECTIVES: The authors aimed to demonstrate that a spectrum of liposculpture definitions can be achieved utilizing power-assisted liposuction (PAL). Also, the authors sought to describe the satisfaction and complication rates in mild-, moderate-, and high-definition groups utilizing the PAL technology. METHODS: The authors designed a single-center retrospective study, including male patients who underwent PAL liposculpture of the chest, abdomen, back, and arms. Inclusion criteria were male patients >18 years of age and body mass index <30 kg/m2. Measured outcomes included extent of definition, complication rates, and levels of satisfaction. RESULTS: Fifty male patients were included in this study between January 2018 and November 2019. The average age was 37.34 years (range = 25-56 years). The average body mass index was 26.4 kg/m2 (range = 24-30 years). A total of 54.3% of patients opted for high definition (HD), 36.4% for moderate definition, and 9.2% for mild definition. There were no major complications. The HD subgroup registered the highest incidence of minor complications (21%). Patient satisfaction levels were high in all 3 subgroups, with the highest scores in the HD subgroup (9.3/10). CONCLUSIONS: A spectrum of definitions can be safely achieved utilizing the PAL technology, with high patient satisfaction in mild-, moderate-, and high-definition liposculpture subgroups and low complication rates.

Variante de colgajo de rotación tipo Hamstring para reconstrucción de úlcera isquiática / Hamstring rotation fl ap variant for ischial ulcer reconstruction

Antecedentes. El colgajo Hamstring es una opción válida para la reconstrucción de úlceras isquiáticas. Las úlceras por presión representan un verdadero desafío para el cirujano plástico. Requieren un tratamiento especializado y multidisciplinario por su alta probabilidad de recidiva y las complicaciones en su manejo. Por lo general, ocurren por presión sostenida sobre la tuberosidad isquiática. Caso clínico. Se presenta el caso de un paciente parapléjico desde el nacimiento secundario a mielomeningocele con diagnóstico actual de úlcera isquiática. Se le realizaron durante 3 años múltiples intentos de cierre quirúrgico alternando medidas conservadoras, sin éxito. A la exploración física presenta una úlcera isquiática izquierda de 6x6 cm a la que se le realizó aseo y desbridación quirúrgica más cierre por medio de un colgajo Hamstring modificado. A los 7 días presentó dehiscencia de herida la cual se manejó de manera conservadora y cierre primario diferido a las 4 semanas. A 8 meses de posoperatorio el paciente se encuentra con buena evolución y con resultado estético y funcional aceptable, por otra parte, se encuentra sin recidiva, lo que ha permitido su reinserción laboral y un buen equilibrio físico-psico-emocional. Conclusión. El objetivo de este colgajo es brindar cobertura al área isquiática sin afectar estructuras adyacentes, lo cual requiere de un amplio conocimiento de la anatomía de la región femoral, así como de los colgados tanto locales como regionales que podemos utilizar para la reconstrucción. Actualmente este colgajo es una opción terapéutica efectiva para el tratamiento de úlceras isquiáticas refractarias en centros que cuentan con cirujanos plásticos no especializados en microcirugía.

Background. The Hamstring fl ap is an adequate option for ischial ulcers reconstruction. Pressure ulcers represent a real challenge for the plastic surgeon. They require specialized and multidisciplinary treatment due to their high recurrence probability and complications in their management. Regularly, pressure ulcers occur when sustained pressure is applied on the ischial tuberosity. Case report. We report a case of a 23-year-old paraplegic male with myelomeningocele complaining for an ischial ulcer. Multiple attempts to surgical closure were made during three years along with conservative management, without success. Physical examination revealed a 6x6 cm left ischial ulcer, which was managed with surgical debridement and closure with a modifi ed Hamstring fl ap. After 7 days, the patient presented wound dehiscence, which was managed conservatively and primary delayed closure after 4 weeks. 8 months postoperatively the patient has a good evolution and an acceptable functional and aesthetic result, without recurrence, which has allowed his reintegration into work and a good physical-psycho-emotional balance. Conclusion. The objective of this fl ap is to provide coverage to the ischial area without aff ecting adjacent structures, which requires a broad knowledge of the anatomy of the femoral region, as well as the local and regional fl aps that can be used for reconstruction. Nowadays this fl ap is an eff ective therapeutic option for the treatment of refractary ischial ulcers in plastis suergery centers without microsurgery.

Experience in the management of acute wounds by dog bite in a hospital of third level of plastic and reconstructive surgery in Mexico.

BACKGROUND: Dog bite injuries represent an important public health problem, involving all levels of care. They can vary in severity, from superficial wounds (skin and subcutaneous tissue) to devitalization and tissue loss, with the presence of systemic infections, aestethic and functional sequels that require specialized treatment. OBJECTIVE: To describe and share the 7-year experience in the management of dog bite wounds in a plastic and reconstructive surgery referral center in Mexico. METHOD: A retrospective study was conducted where all patients with dog bite wounds that came to the plastic and reconstructive emergency department were enrolled from July 2010 to August 2017. The collected patient demographic characteristics included age, age group, and sex. The collected injury variables included anatomical location, wound characteristics, antibiotic therapy and therapeutic management. RESULTS: A total of 416 patients were enrolled, 63% of the dog bites occurred in children under 18 years of age. The majority of the wounds were found in an isolated anatomical region 88.2%. The most frequent location was the face in 61.3%. Of all the cases 74.3% were treated only with primary wound closure, 21.4% also required some reconstructive surgical procedure, 2.9% did not require wound closure, and 1.4% were hospitalized. All patients received prophylactic antibiotics. 2% reported infection after the management with primary wound closure. CONCLUSIONS: The right management of dog bite wounds in all the health care levels improve the patient prognosis. Complex dog bite wounds must be treated immediately by the plastic and reconstructive surgery department in second or third levels of healthcare. Most of the wounds can be managed by primary closure and other reconstructive techniques with confidence.

OBJETIVO: Describir la experiencia de 7 años en el manejo de heridas por mordedura de perro y proponer un algoritmo de manejo en un centro de referencia en cirugía plástica y reconstructiva en México. MÉTODO: Se realizó un estudio retrospectivo en el que se incluyeron todos los registros de pacientes con heridas por mordedura de perro entre julio de 2010 y agosto de 2017. Las variables recabadas fueron edad, sexo, localización anatómica, características de la herida y manejo terapéutico. RESULTADOS: Se obtuvo un total de 416 pacientes. El 63% de las lesiones ocurrieron en menores de 18 años. La mayoría de las heridas (88.2%) fueron aisladas en una región anatómica. La localización más frecuente fue la cara (61.3%). De todos los casos, el 74.3% se resolvieron solo con cierre primario, el 21.4% requirió además algún proceso reconstructivo, el 2.9% no requirió cierre y el 1.4% de los pacientes fueron hospitalizados. Todos los pacientes recibieron antibióticos profilácticos. El 2% reportaron infección posterior al manejo con cierre primario. CONCLUSIONES: El correcto abordaje de las heridas por mordedura de perro en todos los niveles de atención mejora el pronóstico de los pacientes. Las heridas complejas deben ser manejadas inmediatamente en un centro de segundo o tercer nivel con cirugía plástica y reconstructiva. La mayoría de las heridas por mordedura de perro pueden ser reparadas con cierre primario y otras técnicas reconstructivas con seguridad.

Cicatrización normal y patológica: una revisión actual de la fisiopatología y el manejo terapéutico / Current concepts of the approach and treatment of normal and pathological wound healing: a literature review

El conocimiento del proceso de cicatrización normal y patológica es fundamental para todas las especialidades médicas y quirúrgicas que tratan heridas agudas y crónicas, ya que del efecto de estos procesos dependerá el resultado final del tratamiento quirúrgico. En cada tejido y órgano dentro del organismo existen diferentes mecanismos que regulan la función y homeostasis celular, como sucede en el proceso de cicatrización, en donde participan y contribuyen una serie de fases y factores mediados por células y señales químicas. Una cicatrización aceptable es aquella que deja una adecuada cicatriz externa, devuelve la normalidad anatómica y funcional del tejido, con lo que se espera llegar a tener un resultado final con éxito; Sin embargo se debe entender que este proceso es complejo, y pueden también existir variantes anormales, determinadas por ciertos factores que intervienen para dar resultado a una cicatriz patológica, para lo cual existen diferentes tipos de tratamientos específicos y coadyuvantes para cada una de ellas. Objetivo: Conocer los conceptos actuales en el abordaje y tratamiento de la cicatrización normal y patológica, ofreciendo al cirujano una guía práctica basada en los fundamentos de las investigaciones científicas actuales. Material y métodos: Se realizó una revisión bibliográfica de artículos recientes acerca de cicatrización publicados entre 2010 a 2018, con alto nivel de evidencia

The knowledge of normal and pathological wound healing process is essential for all the medical and surgical specialties that treat acute and chronic wounds, because the final result will depend on the effect of these processes. In each tissue and organ within the organism there are different mechanisms that regulate cellular function and homeostasis, as in the wound healing process, where a series of phases and factors mediated by cells and chemical signals participate. Acceptable wound healing, although it leaves an external scar, restores the anatomical and functional homeostasis of the tissue,which is expected to have a successful result; However, it must be understood that this is a complex process, and therefore may also exist abnormal variants, determined by certain factors that lead to pathological wound healing, hence different types of treatments and coadjuvants therapies are available. Objective: Comprehend the current concepts in the approach and treatment of normal and pathological wound healing, offering the surgeon a practical guide based on state of the art evidence, Material and Methods: A literature review of recent articles published between 2010 and 2018 was carried out, with a high level of evidence
