ABSTRACT
El carcinoma baso escamoso (CBE) o metatípico, es considerado un subtipo de carcinoma basocelular (CBC). Con frecuencia es infradiagnosticado ya que no posee características clínicas ni histológicas definidas, por lo que se suele diagnosticar erróneamente como un carcinoma basocelular o espinocelular (CEC). En este artículo se presenta el caso de un paciente masculino de 86 años con un CBE que se expresó en un colgajo cérvico-facial previo. Se ha descrito un alto riesgo de recurrencia y metástasis, lo que supone un pronóstico desfavorable para los pacientes. No existen protocolos terapéuticos estandarizados para esta entidad, sin embargo, el manejo es fundamentalmente quirúrgico. No se encontraron en la literatura reportes previos de carcinoma metatípico en injertos autólogos de piel(AU)
Metatypical or basosquamous carcinoma (BSC) is considered a subtype of basal cell carcinoma (BCC). It is often underdiagnosed due to the lack of defined clinical and histological characteristics, leading to misdiagnosis as either BCC or squamous cell carcinoma (SCC). This article presents a case of an 86-year-old male patient with metatypical carcinoma that manifested in a previous cervicofacial flap. There is a high risk of recurrence and metastasis associated with this condition, leading to an unfavorable prognosis for patients. Although there are no standardized therapeutic protocols for this entity, surgical management is the primary approach. No previous reports of metatypical carcinoma in autologous skin grafts were found in the literature(AU)

La simulación constituye un instrumento beneficioso para la adquisición de destrezas quirúrgicas. Su disponibilidad en países en vías de desarrollo representa un obstáculo importante en la educación quirúrgica contemporánea.Objetivo : Identificar centros de capacitación quirúrgica en Venezuela que utilicen la simulación para el entrenamiento de habilidades técnicas y conocer la opinión de los miembros de la Sociedad Venezolana de Cirugía (SVC) acerca de su uso para desarrollar habilidades en cirugía abierta.Métodos : Estudio transversal y descriptivo. Se enviaron encuestas por correo electrónico a todos los miembros activos de la SVC. Se utilizó estadística descriptiva para el análisis y presentación de los datos.Resultados : De 1115 encuestas enviadas, 111 fueron completadas; 67,6 % de los participantes no tienen conocimientos sobre la existencia de centros de entrenamiento basados en simulación quirúrgica; el 99,1 % están de acuerdo con implementar la simulación como método de capacitación complementario y consideran importante el entrenamiento de habilidades en cirugía abierta; 94,6 % manifestó que el entrenamiento debe estructurarse y ejecutarse en módulos que inicien con tareas básicas para luego avanzar hacia procedimientos más complejos; 75 % de los procedimientos avanzados que deben practicarse con mayor frecuencia corresponden al sistema gastrointestinal, destacando las anastomosis intestinales (74,7 %).Conclusión : la gran mayoría de los cirujanos en las Instituciones de salud de Venezuela no tienen acceso a la simulación como herramienta educativa, a pesar de estar de acuerdo con que su implementación es altamente potenciadora para el desarrollo de habilidades técnicas(AU)
Simulation represents a beneficial tool for acquiring surgical skills. Its availability in developing countries poses a significant obstacle in contemporary surgical education.Objective : To identify surgical training centers in Venezuela that use simulation for technical skills training, and to understand the opinion of members of the Venezuelan Society of Surgery (SVC) regarding its use for developing open surgical skills.Methods : A cross-sectional, descriptive study. Surveys were sent via email to all active SVC members. Descriptive statistics were used for data analysis and presentation.Results : Of the 1,115 surveys sent, 111 were completed. 67.6% of the participants were unaware of the existence of simulation-based surgical training centers. 99.1% agreed with implementing simulation as a complementary training method and considered training in open surgery skills important. 94.6% stated that training should be structured and conducted in modules starting with basic tasks and progressing to more complex procedures; 75% of the advanced procedures that should be practiced more frequently were related to the gastrointestinal system, with intestinal anastomoses (74.7%) being particularly highlighted.Conclusion : The majority of surgeons in Venezuelan healthcare institutions do not have access to simulation as an educational tool, despite agreeing that its implementation is highly beneficial for the development of technical skills(AU)

The reconstruction of the cheek area is a complex problem because the cheek is the most broad area of the face and is close to the aesthetically important region such as eyelids, nose, and mouth. The ultimate purpose of the cheek reconstruction is the restoration of the original shape and function, and establishment of the harmony with the adjacent structure in terms of color, nature and thickness. Various procedures such as skin graft, local flap, free flap, and local flap using skin expansion have been performed for cheek reconstruction. However, no golden principal or indication has been clarified to be imperative. Analyzing our clinical experiences of the cheek reconstruction, we intend to present a general guide of the cheek reconstruction and to assess the advantages and/or disadvantages of the operative methods. Between march of 1989 and August of 1999, we have experienced 154 cases of the cheek reconstruction. There were 52 males and 73 females, and their ages ranged from 3 to 89 years (mean 28.1 years). Preoperative diagnosis were post-burn deformity(n=74), Romberg disease (n=9), post-traumatic deformity(n=7), hemangioma(n=7), nevus(n=7), neurofibroma(n=5), hemifacial microsomia (n=3), lymphangioma(n=3), cancer(n=6), post-hemimandibulectomy(n=1), radical maxillectomy(n=1). The procedures were one stage cervicofacial flap(49 cases), cervicofacial flap following skin expansion(42 cases), local cheek flap (14 cases), deltocervicopectoral flap(2 cases), skin graft(29 cases), free flap(18 cases). Follow up period ranged from 3 to 72 months(mean 11.8 months). Advantages and disadvantages of each procedures were explained. The satisfaction rate was higher in one stage cervicofacial flap and free flap when assessed by both patients and surgeon. There were 3 cases of the ectropion of lower eylids, 4 cases of partial flap necrosis, and 1 case of exposure of tissue expander. The local flap is always the preferred method for the cheek reconstruction and the free flap is the treatment of choice for the cheek contour reconstruction. Selection of the most suitable flap is mandatory depending on the location and size of the defects.

Together, the cheek and neck can be considered as a single anatomic location because skin vascularity, texture and thickness are similar. The cervicofacial flap has been described as the treatment of choice for the cheek defect because of its good mobility and excellent cosmetic result. However, if the defects on the cheek are wider than the length of palpebral fissure of extended to the lower two thirds of the cheek, the conventional cervicofacial flaps would be inadequate in size without the benefit of expansion. Tissue expansion of the cheek and neck is distinguished by a particuarly high rate of complication. Prevention of various complications require careful planning and certain modifications in technique. We have used the following modifications and measures to prevent the complications and to maximize the expansion. 1) Whenever possible, expanders were placed over the rigid foundation such as mandible or posterior neck area after wide undermining. 2) Expanders were placed deep to platysma in the neck area. 3) Following optimal expansion, the further dissection extending to the clavicle and the posterior neck area was performed for optimal mobilization and draping of the expanded skin. 4) The expanded skin was advanced upward on the cervical portion and rotated forward on the cheek portion. 5) The flap should not be draped above the inferior orbital rim and postoperatively the pressure garments were applied to prevent drooping of the expanded skin. We experienced 21 cases of the expanded cervicofacial flaps with above surgical modifications and the expanded cervicofacial flaps can resurface the 95% of cheek defects with minimal complications and excellent cosmetic results.
