    Abstract 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.

    Abstract 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.

    Abstract Opioids are often the mainstay of postoperative pain management, despite strong evidence of their ill effects and potential for long-term addiction. The goal of this study was to quantify opioid use and contrast pain management strategies of multiple international institutions performing fibula free flap reconstruction. A retrospective multicenter cohort study was designed, including five international centers. For inclusion, the patients had to have undergone a primary fibula free flap reconstruction of the mandible. A total of 185 patients were included. The median opioid use across all centers at 72 hours was 133 oral morphine equivalents. The highest utilization was in the USA (P < 0.001), which was approximately six times that of Italy, four times that of Argentina, and twice that of India, despite all centers performing a similar procedure. Based on this study there are clear differences in prescribing practices and ideologies among surgeons from different countries.

    Abstract The training of human resources for health (HRH) is a recurring concern. The Virtual Campus for Public Health (VCPH) - the educational platform of the Pan American Health Organization (PAHO) - seeks to improve access to public health education, emphasizing leadership training for teams that plan, implement, and evaluate policies and educational initiatives.The objective of this work is to present the results of a consultation with experts on the virtual course "Leadership for Educational Management in Health Organizations", as part of a PAHO/VCPH strategy to strengthen leadership capacities for educational management in the Americas.A qualitative action-research study was carried out using the Delphi method with two iterations of consultations (one virtual and one in person) with experts in educational management in health organizations.The results show the importance of eight dimensions of analysis: recipient profiles, competencies, approach and contents, activities, evaluation of and for learning, adaptability, implementation, and monitoring during and after the course.The participation of actors from different geopolitical spheres in the design and implementation of a regional educational initiative fosters adaptations in the context of its implementation and improves the likelihood it will be adopted. This course can play a strategic role as a catalyst in the formation and consolidation of an integrated network of organizations that strengthen educational leadership in the Americas. This study also highlights the value of the methodological strategy used to improve the quality of HRH training.

    Abstract 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.

    Abstract Introduction: The COVID-19 pandemic limited in person presentation of final works and theses for the completion of specializations, masters and doctorates.
    Objective: To describe the experience in remote presentations of summative essays and thesis.
    Materials and methods: A qualitative-quantitative cross-sectional study was carried out. Perceptions of graduates and examiner board members were explored through a questionnaire.
    Results: 54 presentations were included: 53.7% specializations, 40.7% masters and 5.6% doctorates. The average audience number was 34 and distance to the university was 273.6 km. 116 professionals answered: graduates 28.4% and examiner board members 71.6%. They were female gender in 51.5% and 36.1%, respectively. 100% of graduates and 96.3% of examiner board members believed that they were able to present the results of the investigation, and only 3% and 7.3%, respectively, reported technical difficulties. Positive aspects identified by graduates were higher comfort (45.5%), and greater audience number (36.4%); while the examiner board members identified preventing transportation (37,8%) and taking advantage of technologies (35,4%). Graduates identified as negative aspects audience invisibility (33.3%), and potential threat of technical difficulties (27.3%); whilst the examiner board members identified none (31,7%), and potential threat of technical difficulties (20,7%).
    Conclusion: Remote presentations were successful for graduates and examiner board members, and allowed to continue and finish academic postgraduate training.

    Abstract Temporomandibular joint dislocation (TMJ) is an infrequent clinical situation, representing 3% of all the human body's dislocations. The etiological factors reported are associated to alterations typical of the joint or of the muscular-ligament apparatus, or to clinical conditions that may cause dislocation. We present the case of a 46-year-old patient with hereditary hemorrhagic telangiectasia with bilateral dislocation of the TMJ. There are several potential causes (antipsychotics, intubation, etc.) although the deposit of manganese in the basal ganglia that produce extrapyramidal symptoms could be the most consistent cause.

    Abstract Die globale COVID-19 Pandemie stellte in den beiden vergangenen Jahren (2020/2021) vor allem die AO Foundation mit 18000 Mitgliedern und jährlich mehr als 800 internationalen Fortbildungsveranstaltungen auf eine harte Probe. Bisher lag der Schwerpunkt des AO-Ausbildungskonzeptes auf Präsenzunterricht und Hands-on-Training. Ein Großteil der Präsenzveranstaltungen musste abgesagt, verschoben oder aufgrund der regionalen Beschränkungen und Schutzmaßnahmen als reine Online- oder Hybridveranstaltungen umorganisiert werden. AO CMF konnte bereits vor der Pandemie im Bereich der Online-Lehre umfangreiche Erfahrungen sammeln und vermochte den Fortbildungsbetrieb auf reine Online-Veranstaltungen zügig umzusetzen. Die jährlichen „Flagship-Kurse“ in Davos, bisher reine Präsenzveranstaltungen, wurden 2020 pandemiebedingt als internetbasierte Fortbildungsveranstaltungen durchgeführt. Mit „The Traveling Mandible“ wurde erstmals in der Geschichte der AO eine internationale 24-h-Live-Veranstaltung mit Hunderten von Teilnehmern ins Internet übertragen. Als neues Fort- und Weiterbildungsformat konnten sich die interaktiven „AO CMF Study Clubs“ als Online-Fortbildungs- und Diskussionsforen etablieren, die an verschiedenen internationalen Zentren monatlich mit ausgewählten externen Experten durchgeführt werden. Der Online-Kongress „Global Oral Oncology and Reconstruction“ (AO CMF Asia-Pacific) im März 2021 war mit über 1000 internationalen Teilnehmern der bisher meistbesuchte Online-Anlass der AO. Bei allen Einschränkungen der Pandemie, vor allem in Bezug auf AO-Fortbildungsaktivitäten im Präsenzformat, hatte diese Zeit auch positive Auswirkungen auf die Erfahrungen der AO Faculty im Bereich Online-Lehre. „AO CMF Online Campus“, „From the Frontline“, „Study Clubs“, Facebook Discussion Groups und die myAO-Online-Plattform sind nur einige Themen, die nicht zuletzt durch das Verbot von Präsenzveranstaltungen einen substanziellen Schub in den letzten beiden Jahren erfahren haben. In diesem Artikel werden die Aspekte der pandemiebedingten Transformation zur Online-Lehre diskutiert und die Erfahrungen aus der Perspektive von AO CMF beschrieben.

    Abstract Background: Hyperparathyroidism (HPT) is characterised by increased levels of parathyroid hormone (HPT), surgical excision being the only definitive curative option. After establishing the need for surgery, it is essential to identify the parathyroid glands in the preoperative period to use a minimally invasive approach. Negativity and / or discrepancy in first-line studies (ultrasound and Tc-99m MIBI parathyroid scintigraphy) require more accurate images to reduce the likelihood of bilateral cervical exploration or reintervention.
