Microsurgical free flaps for skull base reconstruction following tumor resection: Available techniques and complications / Utilización de colgajos libres microvasculares para la reconstrucción de la base del cráneo secundaria a resecciones tumorales: técnicas disponibles y complicaciones

Introduction: Resection of malignant tumors located in the anterior and middle fossae of the skull base requires thorough anatomical knowledge, as well as experience regarding the possible reconstructive options to resolve the resulting defects. The anatomical and functional relevance of the region, the complexity of the defects requiring reconstruction and the potential complications that can occur, represent a true challenge for the surgical team. The goal of this study is to describe the microsurgical reconstructive techniques available, their usefulness and postoperative complications, in patients with malignant tumors involving the skull base. Materials and method: This observational, retrospective study, included all patients who underwent surgery for malignant craniofacial tumors from January 1st, 2009 to January 1st, 2019 at a University Hospital in Argentina. Only patients who required reconstruction of the resulting defect with a free flap were included. Results: Twenty-four patients required reconstruction with FF; 14 were male (58.3%) and mean age was 54.9 years. Sarcoma was the most frequent tumor histology. Free flaps used were the following: anterolateral thigh, rectus abdominis, radial, latissimus dorsi, iliac crest and fibular. Complications occurred in 6 cases and no deaths were reported in the study group. Conclusion: Free flaps are considered one of the preferable choices of treatment for large skull base defects. In spite of the complexity of the technique and the learning curve required, free flaps have shown to be safe, with a low rate of serious complications. For these patients, the surgical resolution should be performed by a multidisciplinary team. (AU)

Introducción: La resección de los tumores malignos de la base de cráneo anterior y media requieren no solo un amplio conocimiento anatómico, sino también experiencia en las posibles opciones reconstructivas factibles para resolver el defecto generado. La importancia anatómica y funcional de la región, la complejidad de los defectos a reconstruir y las posibles complicaciones que pueden desarrollar representan un verdadero desafío para el equipo quirúrgico. El objetivo del presente trabajo es exponer las posibles opciones reconstructivas microquirúrgicas, su utilidad y las complicaciones postoperatorias en pacientes con tumores malignos que comprometen la base de cráneo. Materiales y método: Se realizó un estudio observacional retrospectivo de todos los pacientes operados de tumores malignos craneofaciales en el período comprendido entre el primero de enero de 2009 al primero de enero de 2019 en un hospital universitario de Argentina. Se incluyeron solo aquellos pacientes en los que fue necesario reconstruir el defecto a través de un colgajo libre (CL). Resultados: Veinticuatro pacientes requirieron reconstrucción con CL. Catorce fueron varones (n = 14 [58,3%]) y la media de edad fue de 54,9 años. La variedad tumoral histológica más frecuente fue el sarcoma. Los tipos de CL utilizados fueron los siguientes: anterolateral de muslo, recto anterior del abdomen, radial, dorsal ancho, cresta iliaca y fibular fueron los CL utilizados. Se reportó una tasa global de complicaciones del n = 6 (25%). Un solo paciente presentó isquemia del colgajo. No hubo mortalidad asociada. Conclusión: Los CL representan una de las primeras opciones en el tratamiento en defectos grandes de la base de cráneo. A pesar de la complejidad de la técnica y la curva de aprendizaje necesaria, los CL han demostrado ser seguros con bajas tasas de complicaciones graves. La resolución quirúrgica de estos pacientes se debe realizar por un equipo multidisciplinario. (AU)

Giant Cell Tumor of the Carotid Body: A Rare Tumor with Malignant Potential.

Introduction: Carotid body tumors (CBTs) are certainly unusual. They are vascular lesions originating from paraganglionic cells, located at the common carotid artery (CCA) bifurcation. They represent less than 0.5% of head and neck tumors, approximately 1-3 cases per million. Malignant CBTs are extremely rare; in the literature, published rates on average are < 10%. The diagnostic criteria for malignancy should be based on the finding of distant metastasis. Due to its unpredictable nature and its malignant potential, diagnosis before metastasis and complete surgical resection are the keys to a favorable prognosis. Case Report: Given little experience in CBTs, its biology and treatment remain uncertain. We present the case of a 48-years-old patient, with a mass on the left side of the neck that was found to be a vast CBT with suspicious histopathology. Its size, rare location, pathologic findings, and management strategy applied for its treatment, illustrate an unusual case that highlights the importance of its publication. Conclusions: CBT is rare, but subject to cure lesion if resected without metastatic or residual disease. This is why surgery should be performed whenever possible and why it is so necessary to study this pathology thoroughly and to take it into account in the differential diagnosis.

Teaching strategies and outcomes in 3 different times of the COVID-19 pandemic through a dynamic assessment of medical skills and wellness of surgical trainees.

BACKGROUND: The coronavirus disease 2019 pandemic had a substantial impact on surgical training programs. This study describes the teaching strategies and outcomes in 3 different times of the coronavirus disease 2019 pandemic through a dynamic assessment of medical skills and well-being of trainees. METHODS: Three surveys were administered during 2020 to general surgery residents and fellows in a university hospital in Argentina. Perceptions on the impact of coronavirus disease 2019 were described. The stress rate and risk factors were analyzed. RESULTS: The study included 124 answers. In total, 59% were men, 82% of trainees reported concerns about the loss of surgical skills in early phase 1. Time spent with academic activities increased in 94.5% of the cases. Owing to the prompt implementation of changes, by the end of 2020, 73% participated in a greater number of procedures (P = .003); personal protective equipment use related problems dropped from 40% to 14% (P = .031), and the lack of adequate spaces where trainees could express reduced from 28% to zero. Half of the trainees felt stressed, and 18% required psychological assistance; reporting problems with personal protective equipment use was identified as a risk factor (P = .012). CONCLUSION: Assessing trainees' perceptions at 3 different times of the coronavirus disease 2019 pandemic enabled the implementation of dynamic changes. The negative impact on surgical training was partially offset by the optimal use of virtual learning. Half of them felt stressed, identifying problems in the use of personal protective equipment as a predisposing factor.

Recommendations regarding emergency head and neck procedures during coronavirus disease-2019.

The coronavirus disease-2019 (COVID-19) has spread globally and is considered a world health emergency. Healthcare professionals represent an important percentage of the infected population, with otolaryngologists and head and neck surgeons at particular risk. Elective procedures have been strongly discouraged, but urgent disorders still entail a hazardous setting. We performed a non-systematic review of the publications and guidelines regarding Head and Neck surgical emergencies management in the context of the COVID-19 pandemic. The literature describing management of the disease was also reviewed to adapt conventional treatment to the present circumstances. A concise and specific compilation of practical recommendations was made with the aim of improving management of emergencies involving the head and neck region, while offering a safe alternative for patients and healthcare providers. In addition, we have made a brief summary of how these recommendations were adapted based on our socio-economic background and available health resources.

La enfermedad del coronavirus-2019 (COVID-19) se ha extendido a nivel mundial y se considera una emergencia sanitaria mundial. Los profesionales sanitarios representan un porcentaje importante de la población infectada, y los otorrinolaringólogos y cirujanos de cabeza y cuello corren un riesgo especial. Se han desaconsejado enérgicamente los procedimientos electivos, pero los trastornos urgentes aún implican un entorno peligroso. Realizamos una revisión no sistemática de las publicaciones y guías sobre el manejo de emergencias quirúrgicas de cabeza y cuello en el contexto de la pandemia de COVID-19. También se revisó la literatura que describe el manejo de la enfermedad con el fin de adaptar el tratamiento convencional a las circunstancias actuales. Se realizó una recopilación concisa y específica de recomendaciones prácticas con el objetivo de mejorar el manejo de las emergencias que involucran la región de la cabeza y el cuello, al tiempo que ofrece una alternativa segura para los pacientes y los proveedores de atención médica. Además, hemos hecho un breve resumen de cómo se adaptaron estas recomendaciones en función de nuestros antecedentes socioeconómicos y los recursos de salud disponibles.

Total Temporomandibular Joint Replacement and Simultaneous Orthognathic Surgery Using Computer-Assisted Surgery.

BACKGROUND: Disorders of the temporomandibular joint (TMJ) are frequent and are usually associated with other disorders of the facial skeleton. Surgery might be needed to correct TMJ anatomy and function and, in cases where pathologies coexist, a two-stage corrective surgery might be needed. However, the current fashion of single-stage procedures is feasible with the aid of new technologies such as computer-assisted surgery (CAS). This is a step forward toward performing complex procedures such as a TMJ replacement with simultaneous orthognathic surgery. CAS allows designing patient-fitted prosthesis and more predictable and accurate surgeries. Moreover, intraoperative development can be controlled in real time with intraoperative navigation, and postoperative results can be measured and compared afterwards. AIMS: The primary purpose of this article is to present the protocol used in our institution for orthognathic surgery associated with unilateral and bilateral TMJ replacement with patient-fitted prostheses guided with CAS. MATERIALS AND METHODS: We present two cases to illustrate our protocol and its results. RESULTS: In the first case, the difference in millimeters between planning and surgical outcomes was 1.72 mm for the glenoid component and 2.16 mm for the condylar prosthesis; for the second case, differences in the right side were 2.59 mm for the glenoid component and 2.06 mm for the ramus, and in the left side, due to the anatomy the difference was a little greater, without clinical significance. CONCLUSION: Combined surgery of the midface and mandible with total TMJ replacement is feasible and beneficial for the patient. CAS facilitates the planning and design of custom-fit prosthesis and execution of these procedures.

Staff senior versus staff junior en cirugía tiroidea. Supervisada: resultados y desafíos pedagógicos.

OBJETIVO: En el presente trabajo nos planteamos analizar cuál es la visión del cirujano supervisado que realiza una cirugía tiroidea acerca de qué y cómo se aprende en el ámbito del quirófano y cuáles son las características de este espacio de aprendizaje. Se analizaron las posibles diferencias respecto a la morbilidad posoperatoria del paciente cuando es tratado por un supervisor o un supervisado. MÉTODO: Estudio observacional cualitativo-cuantitativo mediante un cuestionario sin opciones prefijadas, tanto a los supervisores como a los supervisados. También se analizó una base de datos retrospectiva considerando la estadía, los tiempos operatorios y las complicaciones agudas y crónicas según el operador (supervisado o supervisor). RESULTADOS: La experiencia profesional involucra otras acciones complejas que deben visibilizarse para ser enseñadas. Tanto supervisores como supervisados reconocieron al quirófano como un contexto socializador a través de aprendizajes supervisados. No existieron diferencias estadísticas en las complicaciones ni en la estadía hospitalaria entre cirujanos expertos y cirujanos en formación supervisados. CONCLUSIONES: Este trabajo resulta ser un aporte a quienes enfrentan el desafío de facilitar el aprendizaje dentro de la sala de operaciones. Se espera que ayude a inspirar acciones planificadas que jerarquicen y aporten calidad a la tarea educativa ineludible. OBJECTIVE: In the present work we propose to analyze what is the vision of the supervised surgeon who performs thyroid surgery about what and how it is learned in the operating room and what are the characteristics of this learning space. Possible differences regarding the postoperative morbidity of the patient when treated by a supervisor or a supervised person were analyzed. METHOD: Qualitative-quantitative observational study using a questionnaire without predefined options, for both supervisors and supervisees. A retrospective database was also analyzed considering hospital stay, operative times, acute and chronic complications according to operator (supervised or supervisor). RESULTS: Professional expertise involves other complex actions that must be made visible to be taught. Both supervisors and supervisees recognized the operating room as a socializing context through supervised learning. There were no statistical differences in complications and / or hospital stay between expert surgeons and supervised surgeons in training. CONCLUSIONS: This work turns out to be a contribution to those who face the challenge of facilitating learning in the operating room. It is hoped that it will help inspire planned actions that prioritize and add quality to the inescapable educational task.

Head and neck sarcomas: treatment outcomes in a tertiary referral center in Argentina.

PURPOSE: To analyze the clinical findings, management, and results of oncological treatments and to identify prognostic factors in patients diagnosed with head and neck sarcoma. METHODS: We performed a retrospective analysis including 48 adult patients with primary head and neck sarcomas, treated between 2006 and 2018 in a referral center of Argentina. RESULTS: The median follow-up time was 44 months (range: 4-146 months). Five-year overall survival was 68%. On univariate analysis, radiation-induced sarcomas (p=0.038) had worse survival. Five-year disease-free survival was 58% and local recurrence at 2 years was 22.7%. On multivariate analysis, positive/close resection margins (p=0.031), radiation-induced sarcomas (p=0.037), and mandibular and oral cavity location (p=0.002) were independent prognostic factors associated to local recurrence and shorter disease-free survival. CONCLUSION: Head and neck sarcomas are a rare entity. Surgery is feasible in more than 80% of patients, with an acceptable overall and disease-free survival. Radiation-induced sarcomas, location in the mandible and oral cavity, and close margins were significant prognostic factors in our population.

Clear cell odontogenic carcinoma: a rare pathology with an innovative resolution.

Clear cell odontogenic carcinoma (CCOC) is an uncommon condition that has been considered malignant since 2005. The clinical presentation usually involves an asymptomatic swelling, which typically affects the anterior mandible in middle-aged women; it has neither clinical nor radiological defining features. Immunohistochemical analysis usually aids diagnosis, as clear cells are also associated with other clear cell carcinomas and benign tumors. Radical surgery is the gold standard of treatment and usually needs microsurgical reconstruction with bone transference for restoration of facial anatomy and adequate function.  We present the case of a young woman with CCOC whose tumor removal and reconstructive surgery were planned virtually and assisted by intraoperative navigation. The novelty of the reconstructive procedure was the replacement of the fibula cutting guides for intraoperative navigation of the osteotomies. We present a brief review of CCOC and the benefits of using computer-assisted surgery (CAS) in high-complexity cases like this one.

Tracheostomy in the intensive care unit: Guidelines during COVID-19 worldwide pandemic.

PURPOSE: COVID-19 has become a pandemic with significant consequences worldwide. About 3.2% of patients with COVID-19 will require intubation and invasive ventilation. Moreover, there will be an increase in the number of critically ill patients, hospitalized and intubated due to unrelated acute pathology, who will present underlying asymptomatic or mild forms of COVID-19. Tracheostomy is one of the procedures associated with an increased production of aerosols and higher risk of transmission of the virus to the health personnel. The aim of this paper is to describe indications and recommended technique of tracheostomy in COVID-19 patients, emphasizing the safety of the patient but also the medical team involved. MATERIALS AND METHODS: A multidisciplinary group made up of surgeons with privileges to perform tracheostomies, intensive care physicians, infectious diseases specialists and intensive pulmonologists was created to update previous knowledge on performing a tracheostomy in critically ill adult patients (>18 years) amidst the SARS-CoV-2 pandemic in a high-volume referral center. Published evidence was collected using a systematic search and review of published studies. RESULTS: A guideline comprising indications, surgical technique, ventilator settings, personal protective equipment and timing of tracheostomy in COVID-19 patients was developed. CONCLUSIONS: A safe approach to performing percutaneous dilational bedside tracheostomy with bronchoscopic guidance is feasible in COVID-19 patients of appropriate security measures are taken and a strict protocol is followed. Instruction of all the health care personnel involves is key to ensure their safety and the patient's favorable recovery.
