RESUMO
Introducción y objetivo: Existen numerosos procedimientos en los cuales más allá de la adecuada manipulación del músculo temporal y del cierre craneal, los pacientes pueden presentar defecto óseo, muscular por atrofia y asimetría facial consecuente, provocando un malestar psicológico y deterioro funcional. Nuestro equipo decidió aunar los conocimientos de cirugía plástica y aplicarlos a reconstrucciones craneales con lipotranferencias en pacientes post neuroquirúrgicos. El objetivo del siguiente trabajo consiste en presentar los resultados en una serie de pacientes donde se aplicó la mencionada técnica. Materiales y métodos: Durante 2022 se realizaron 45 procedimientos de lipotransferencias para corrección de defectos craneofaciales, de los cuales 29 fueron femeninos y 16 masculinos. Todos presentaban el antecedente quirúrgico de craneotomías pterionales y sus variantes, abordajes orbitocigomáticos y transcigomáticos, con el consiguiente déficit de volumen. Resultados: El procedimiento se realizó de manera ambulatoria, con anestesia local y en un tiempo promedio de 30 a 40 minutos. Se utilizó como zona donante la región hemiabdominal inferior; procesamiento de la grasa mediante técnica de decantación e inyección en la zona receptora a nivel craneo facial. Los pacientes toleraron el procedimiento adecuadamente sin complicaciones intraoperatoria ni eventos sobreagregados. Conclusión: La lipotransferencia constituye una técnica mínimamente invasiva, con baja morbilidad y altas tasas de efectividad en cuanto al resultado estético y a la satisfacción por parte del paciente. Es una herramienta que todo neurocirujano debería considerar ante un defecto secundario a un abordaje anterolateral a la base del cráneo(AU)
Background: There are numerous procedures in which, beyond adequate manipulation of the temporalis muscle and cranial closure, patients may present bone and muscle defects due to atrophy and consequent facial asymmetry, causing psychological discomfort and functional deterioration. Our team decided to combine the knowledge of plastic surgery and apply it to cranial reconstructions with fat transfers in post neurosurgical patients. The objective of the following work is to present the results in a series of patients where the aforementioned technique was applied. Methods: During the year 2022, 45 fat transfer procedures were performed for the correction of craniofacial defects, of which 29 were female and 16 male. All had a surgical history of pterional craniotomies and their variants, orbitozygomatic and transzygomatic approaches, with the consequent volume deficit. Results: The procedure was performed on an outpatient basis, with local anesthesia and in an average time of 30 to 40 minutes. The lower hemiabdominal region was used as the donor area, processing the fat using the decantation technique and injection into the receptor area at the craniofacial level. The patients tolerated the procedure adequately without intraoperative complications or superadded events. Conclusion: Fat transfer is a minimally invasive technique, with low morbidity and high rates of effectiveness in terms of aesthetic results and patient satisfaction. It is a tool that every neurosurgeon should consider when faced with a defect secondary to an anterolateral approach to the skull base(AU)

The patients tolerated the procedure adequately without intraoperative complications or superadded events. Conclusion: Fat transfer is a minimally invasive, effective, and cost-effective technique that plastic surgery offers us to implement in post-neurosurgical patients, as it achieves natural results that stand the test of time.
RESUMO
Nowadays the reconstruction of craniofacial defects can be performed with different kinds of materials, which include the bone and the so-called biomaterials, which have the advantage of not needing a surgical site donor. Among these materials, great attention is given to polymers. In this large group, current attention is focused on the castor oil polymer, since this polymer is biocompatible, low cost, and has adequate strength for reconstruction of the craniomaxillofacial complex. This study aims to report the use of a prosthetic castor oil polymer for reconstruction of extensive defect, caused by a trauma, in the temporoparietal region.
RESUMO
Encephalocele is defined as protrusion of cranial contents beyond the normal confines of the skull. Although most encephalocele cases have a congenital etiology, fractures of the skull base can cause traumatic encephalocele. In most encephalocele cases, the bone defect presents reduced dimensions and the endoscopic treatment is generally performed to reconstruct the area using mucosal and/or fat grafts. This article sought to report on a rare case of traumatic encephalocele associated with an extensive defect of the anterior skull base. This case was treated via transcranial access, and reconstruction was performed using titanium mesh in conjunction with a pericranium flap.
