Los procedimientos reconstructivos en cabeza y cuello son todo un desafío debido a que son áreas expuestas, con gran movimiento, y desempeñan funciones esenciales de la vida como el habla, la alimentación y la respiración. El colgajo supraclavicular es un colgajo locorregional, fasciocutáneo, fino, axial a la arteria supraclavicular, versátil, con baja morbilidad, que se usa ampliamente para cubrir defectos en cuello y sector inferior de la cara ya que proporciona tejido similar al de estas regiones, y técnicamente rápido y sencillo.Se puede usar en asociación con otros colgajos para reconstrucciones complejas. Es un colgajo infrautilizado que es una buena alternativa frente a los colgajos tradicionales musculares regionales y libres. Las principales indicaciones son secuelas de quemaduras como las contracturas esternomentonianas, defectos oncológicos ya sea piel o mucosa oral, faringostomas y fístulas traqueocutáneas. Se mencionan 3 casos clínicos en los cuales se llevó a cabo un colgajo supraclavicular en el Hospital Pasteur, Montevideo, Uruguay.

Reconstructive head and neck procedures are challenging because they are exposed areas, are highly mobile, and perform essential life functions such as speaking, eating, and breathing. The supraclavicular flap is a locoregional, fasciocutaneous, thin flap, axial to the supraclavicular artery, versatile, with low morbidity, which is widely used to cover defects in the neck and lower face since it provides tissue similar to that of these regions, and Technically fast and simple. It can be used in association with other flaps for complex reconstructions. It is an underutilized flap that is a good alternative to traditional regional and free muscle flaps. The main indications are sequelae of burns such as sternomental contractures, oncological defects in the skin or oral mucosa, pharyngostomies and tracheocutaneous fistulas. Three clinical cases are mentioned in which a supraclavicular flap was performed at the Pasteur Hospital, Montevideo, Uruguay

Objective: To retrospectively analyse the efficacy of surgerical comprehensive treatment for hypopharyngeal cancer. Methods: Four hundred and fifty-six cases of hypopharyngeal squamous cell carcinoma treated from Jan 2014 to Dec 2019 were analyzed retrospectively, including 432 males and 24 females, aged 37-82 years old. There were 328 cases of pyriform sinus carcinoma, 88 cases of posterior pharyngeal wall carcinoma, and 40 cases of postcricoid carcinoma. According to American Joint Committe on Cancer(AJCC) 2018 criteria, 420 cases were of stage Ⅲ or Ⅳ; 325 cases were of T3 or T4 stage. Treatment methods included surgery alone in 84 cases, preoperative planned radiotherapy plus surgery in 49 cases, surgery plus adjuvant radiotherapy or concurrent chemoradiotherapy in 314 cases, and inductive chemotherapy plus surgery and adjuvant radiotherapy in 9 cases. The primary tumor resection methods included transoral laser surgery in 5 cases, partial laryngopharyngectomy in 74 cases, of them 48 cases (64.9%) presented with supracricoid hemilaryngopharyngectomy, total laryngectomy with patial pharyngectomy in 90 cases, total laryngopharyngectomy or with cervical esophagectomy in 226 cases, and total laryngopharyngectomy with total esophagectomy in 61 cases. Among 456 cases, 226 cases received reconstruction surgery with free jejunum transplantation, 61 cases with gastric pull-up, and 32 cases with pectoralis myocutaneous flaps. All patients underwent retropharyngeal lymph node dissection, and high-definition gastroscopy was performed during admission and follow-up. SPSS 24.0 software was used to analyze the data. Results: The 3-year and 5-year overall survival rates were respectively 59.8%, and 49.5%. The 3-year and 5-year disease specific survival rates were respectively 69.0% and 58.8%. Total metastasis rate of retropharyngeal lymph nodes was 12.7%. A total of 132 patients (28.9%) suffered from simultaneous and metachronous multiple primary carcinoma of the hypopharynx. Multivariate Logistic regression analysis showed that T3-4 disease, cervical lymph node metastasis, retropharyngeal lymph node metastasis and postoperative adjuvant radiotherapy were independent factors affecting the prognosis of patients (all P<0.05). As of April 30, 2022, a total of 221 patients died during follow-up, of 109 (49.3%) with distant metastases, which were the main cause of death. Conclusions: The efficacy of comprehensive treatment for hypopharyngeal cancer can be improved by accurate preoperative evaluation, improved surgical resection, active retropharyngeal lymph node dissection and full process intervention of the second primary cancer.

Resumen El paraganglioma carotideo es un tumor infrecuente, originado de las células de la cresta neural. Raramente son secretores y tienen un bajo potencial maligno. El diagnóstico es difícil y requiere una alta sospecha clínica, combinada con estudios imagenológicos. Su tratamiento está basado en la cirugía, con especial cuidado de las estructuras vasculonerviosas que se encuentran en intimo contacto. Se describe la casuística de paragangliomas de cuerpo carotídeo en Clínica Las Condes y compararla con una revisión de la literatura actualizada del tema.

Abstract Carotid paraganglioma is a rare tumor, originated from neural crest cells. Usually they lack hormone secretion function, and have a low malignant potential. Diagnosis is difficult, and requires high clinical suspicious, combined with image and pathologic findings. Its treatment is based on surgery, with special care of close anatomic relation with important vascular-nervous structures. Here, we present cases of carotid paragangliomas evaluated at Clinica Las Condes comparing them with an updated literature review.

Abstract Introduction: General anesthesia causes pulmonary atelectasis within few minutes of induction. This can have significant impact on postoperative outcome of cancer patients undergoing prolonged reconstructive surgeries. Objective: The purpose of this study was to evaluate the impact of sonographically detected perioperative atelectasis on the need for postoperative oxygen supplementation, bronchodilator therapy and assisted chest physiotherapy in patients undergoing free flap surgeries for head and neck carcinoma. Methods: Twenty eight head and neck cancer patients underwent bilateral pulmonary ultrasonographic assessments before and after lung surgery. Lung ultrasound scores, serum lactate, and PaO2/FiO2 ratio were measured both at the beginning and at end of the surgery. Patients were scanned in the supine position and the number of single and confluent B lines was noted. These values were correlated with the need for oxygen therapy, requirement of bronchodilators and total weaning time to predict the postoperative outcome. Other factors affecting weaning were also studied. Results: Among twenty eight patients, seven had mean lung ultrasound score of ≥10.5 which correlated with prolonged weaning time (144.56±33.5min vs. 66.7±15.7min; p = 0.005). The change in lung ultrasound score significantly correlated with change in PaO2/FiO2 ratio (r = −0.56, p = 0.03). Elevated total leukocyte count >8200 ΜL and serum lactate >2.1 mmoL/L also predicted prolonged postoperative mechanical ventilation. Conclusion: This preliminary study detected significant levels of perioperative atelectasis using point of care lung ultrasonography in head and neck cancer patients undergoing long duration surgical reconstructions. Higher lung ultrasound scores highlighted the need for frequent bronchodilator nebulizations as well as assisted chest physiotherapy and were associated with delayed weaning. We propose more frequent point of care lung ultrasonographic evaluations and use of recruitment maneuvers to reduce the impact of perioperative pulmonary atelectasis.

Resumo Introdução: A anestesia geral causa atelectasia pulmonar poucos minutos após sua indução. Isso pode ter um impacto significativo no resultado pós-operatório de pacientes com câncer submetidos a cirurgias reconstrutivas prolongadas. Objetivo: Avaliar o impacto das atelectasias perioperatórias detectadas por ultrassonografia na necessidade de suplementação pós-operatória de oxigênio, terapia broncodilatadora e fisioterapia respiratória assistida em pacientes com carcinoma de cabeça e pescoço submetidos a cirurgias com uso de retalho livre. Método: Foram submetidos a avaliações ultrassonográficas pulmonares bilaterais antes e após a cirurgia 28 pacientes com câncer de cabeça e pescoço. Os escores de ultrassonografia pulmonar, lactato sérico, razão PaO2/FiO2 foram medidos no início e no fim da cirurgia. Os pacientes foram avaliados na posição supina e o número de linhas B confluentes e únicas foi observado. Esses valores foram correlacionados com a necessidade de oxigenoterapia, necessidade de broncodilatadores e tempo total de desmame para predizer o resultado pós-operatório. Outros fatores que afetam o desmame também foram estudados. Resultados: Entre os 28 pacientes, sete apresentaram escore médio de ultrassonografia pulmonar ≥ 10,5, que se correlacionou com o tempo de desmame prolongado (144,56 ± 33,5 minutos vs. 66,7 ± 15,7 minutos; p = 0,005). A mudança no escore de ultrassonografia pulmonar correlacionou-se significantemente com a mudança na razão PaO2/FiO2 (r = −0,56, p = 0,03). A contagem total elevada de leucócitos > 8200 uLe o nível de lactato sérico >2,1 mmoL/L também previram ventilação mecânica pós-operatória prolongada. Conclusão: Este estudo preliminar detectou um nível significante de atelectasia perioperatória com ultrassonografia pulmonar no local de atendimento em pacientes com câncer de cabeça e pescoço submetidos a reconstruções cirúrgicas de longa duração. Escores mais altos de ultrassonografia pulmonar enfatizaram a necessidade de nebulizações broncodilatadoras frequentes e fisioterapia respiratória assistida e foram associados a desmame tardio. Propomos avaliações ultrassonográficas pulmonares mais frequentes no local de atendimento e o uso de manobras de recrutamento para reduzir o impacto das atelectasias pulmonares perioperatórias.

INTRODUCTION: The prevalence of malnutrition is high among head and neck cancer (HNC) patients and negatively impacts their quality of life, treatment, and survival rates. OBJECTIVE: To identify preoperative nutritional variables capable of predicting postoperative complications in surgically treated HNC patients. METHODS: This was a prospective cohort study of HNC patients referred for surgery as initial treatment. RESULTS: Sixty patients were included in the study; they had a median age of 65.5 years, were mostly me n (85%), and most had low education levels (90%) and low household income (78.3%). The incidence rate of severe postoperative complications (grades II, III, IV, and V according to the Clavien-Dindo grading system) was found to be 50%. The nutritional variables under investigation, namely calf circumference (CC), triceps skinfold, body mass index, and adductor pollicis muscle thickness were shown to predict postoperative complications in HNC patients, especially CC, which was found to be an independent predictor of complications (OR=0.8; 95%CI: 0.65­0.96). Each 1-cm increase in calf circumference was associated with a 20% decrease in the risk of postoperative complications. CONCLUSION: Our findings show the nutritional variables studied are useful in the prognostic assessment of HNC surgery.

OBJECTIVE@#To discover the factors that may affect the use of selective tracheostomy among patients who have undergone head and neck surgeries with free flap reconstruction, so that the patients will not need tracheostomy nor receive the unnecessary treatment.@*METHODS@#Five hundred and thirty-three patients who had undergone head and neck surgery with free flap reconstruction operated by the same team of surgery at Department of Oral and Maxillofacial Surgery at Peking University School of Stomatology from 2015 to 2016 were reviewed. Three hundred and twenty-one (60.2%) of these patients underwent selective tracheostomy. All the patients' demographic information, operation-related information, prior treatments, comorbidities and complications were recorded and analyzed.@*RESULTS@#The patients with defects of the tongue, mouth floor, oropharynx and bilateral mandible, who underwent neck dissection and with previous radiotherapy and smoking habit were more likely to get selective tracheostomy. Usage of bulky soft tissue flap might also add to the risk of airway obstruction and the need of selective tracheostomy, while other factors were not significantly related to the risk of postoperative airway obstruction and the patients could be kept safe without selective tracheostomy. Most cases without tracheostomy were kept safe except one case, while 8.39% of the patients with tracheostomy suffered from tracheostomy related complications, mainly pneumonia and hemorrhage of the tracheostomy wound, yet none led to serious consequences or even death.@*CONCLUSION@#Selective tracheostomy is not necessary for patients who have undergone head and neck surgeries with free flap reconstruction except that there are defects at the tongue, oropharynx and mandible. Neck dissection, bulky soft tissue flap reconstruction, previous radiotherapy and smoking habit may also add to the risk of postoperative airway obstruction, while a favorable decision would involve a combination of all the above factors to assure the safety of the postoperative airway for the patients undergone head and neck surgeries with free flap reconstruction.

A sobrevivência de pacientes com câncer de cabeça e pescoço vêm melhorando, entretanto, algumas deformidades podem ocorrer devido dos tratamentos cirúrgicos que geram mutilações bucomaxilofaciais como perda de dentes, estruturas do palato, língua ou assoalho, resultando em alterações na fonética, mastigação e deglutição. Nesses casos há a necessidade que seja realizado uma reabilitação protética buscando torná-los indivíduos com menos problemas sociais, psicológicos e físicos, visto que mais procedimentos cirúrgicos estão contra indicados para solucionar os efeitos colaterais gerados pelo tratamento das neoplasias. Esse tipo de reabilitação protética com prótese ou placa obturadora possibilita benefícios na fonética, facilita a convivência social e atividades nutricionais como alimentação e deglutição, permitindo ao paciente uma vida com menos constrangimentos. Este trabalho tem como objetivo relatar dois casos clínicos onde os pacientes foram submetidos a reabilitação com placa obturadora palatina feitos após cirurgias oncológicas. Os pacientes de gêneros diferentes e com comunicações buco-nasal similares receberam o mesmo planejamento reabilitador que foram confeccionadas a partir de um molde que foi enviado ao laboratório. Após a instalação foi possível verificar que houve sucesso no tratamento, notando uma melhora imediata comprovando a eficácia do método reabilitador(AU)

This paper relates two clinical cases where patients were recovered with a palatal splint made after oncological surgeries. Survival of patients and necks can occur, however, some deformities can occur during oral and maxillofacial treatment, such as the appearance of teeth, palate structures, mutilations or posterior jaws, leading to changes in aesthetics, surgery and swallowing. If the need to perform a prosthetic rehabilitation is necessary so that the results are seen with less problems, psychological and physical, that more procedures are performed so that the effects of neoplasms are contraindicated by the treatment. This type of prosthetic rehabilitation with prosthesis or obturator plate provides benefits in phonetics, facilitates social coexistence and nutritional activities such as eating and swallowing, allowing the patient a life with less constraints. Patients of different genders and with similar oral and nasal communications received the same rehabilitation plan that were made from a mold that was sent to the laboratory. After installation, it was possible to verify that the treatment was successful, noting an immediate improvement, proving the effectiveness of the rehabilitation method(AU)

Resumen Introducción: La pandemia COVID-19 generó una reestructuración en la atención quirúrgica mundialmente debido a su alta transmisibilidad y la inherente limitación de los recursos humanos y materiales disponibles. Objetivo: Describir el impacto de la pandemia COVID-19 en el Equipo de Cirugía Cabeza y Cuello del Complejo Asistencial Barros Luco Trudeau (CABL) en su ejecución clínico-quirúrgica y la secuenciación organizada de las medidas sanitarias aplicadas a lo largo del tiempo durante los primeros 150 días de iniciada la pandemia en Chile. Materiales y Método: Realizamos una revisión retrospectiva de los pacientes sometidos a cirugía y/o evaluados ambulatoriamente durante el período COVID-19 comprendido entre el 3 de marzo y el 31 de julio de 2020, comparado con el mismo intervalo de tiempo de 2019. Características clínicas y medidas sanitarias empleadas durante este período fueron sintetizadas. Resultados: Detectamos un descenso del 64% en atención ambulatoria y un descenso del 58% en la carga quirúrgica, comparado con el año 2019. Durante el período COVID-19 de 2020, un total de 61 pacientes fueron sometidos a intervención quirúrgica. La principal indicación de cirugía fue cáncer en un 75,4% (46). No se reportaron pacientes contagiados por COVID-19 en los 14 días siguientes a la hospitalización. Se discuten las consideraciones perioperatorias empleadas y restricciones nacionales/institucionales sanitarias. Conclusión: La crisis sanitaria mundial secundaria al COVID-19 generó una reducción en las atenciones ambulatorias y cirugías realizadas por Equipo de Cabeza y Cuello CABL. A pesar de las restricciones sanitarias, organizamos estratificadamente la atención para preservar la resolución de casos críticos no diferibles en cabeza y cuello.

Introduction: The COVID-19 pandemic generated a restructuring of surgical care worldwide due to the disease's high transmissibility and the inherent limitation of available human and material resources. Aim: The study's aim was to describe the impact of the COVID-19 pandemic on the head and neck surgery team at Complejo Asistencial Barros Luco Trudeau (CABL) in clinical-surgical execution and organization of sanitary sequencing measures implemented over time during the first 150 days after the pandemic started in Chile. Materials and Method: We performed a retrospective review of patients undergoing surgery or outpatient evaluation during the COVID-19 period from 03-03-2020 to 07-31-2020, compared to the same time interval in 2019. Clinical characteristics and sanitary measures used during this period were synthesized. Results: We detected a 64% decrease in outpatient care and a 58% decrease in surgical load from 2019. During the COVID-19 period of 2020, a total of 61 patients underwent surgical intervention. The main indication for surgery was cancer, in 75.4% of patients (46). COVID-19 was not reported in any patients in the 14 days following hospitalization. We discussed the perioperative considerations used and the national/institutional sanitary restrictions. Conclusions: The global health crisis to COVID-19 generated a reduction in outpatient care and surgeries performed by the CABL head and neck team. Despite health restrictions, we organized care stratified to preserve critical head and neck non-deferrable cases.

Resumen La mayoría de los servicios de salud han experimentado un aumento de los costos asociados a la atención de salud lo que ha llevado a adoptar medidas para optimizar la costo-efectividad de los servicios otorgados. Desde esa perspectiva surge la atención de salud basada en el valor. El concepto de "calidad en la atención de salud" se ha definido como el grado en el cual los servicios de salud aumentan la posibilidad de generar ciertos desenlaces en salud a los que se aspira. Los indicadores de calidad de clasifican en indicadores de estructura, de proceso, y de desenlace. Los indicadores de estructura se refieren a las características del sistema de salud o de la institución hospitalaria. Los indicadores de proceso se refieren a los que el proveedor de servicios de salud realiza para el proceso de atención en salud, mientras que los indicadores de desenlace se refieren a los resultados del proceso en el paciente. El objetivo de la presente revisión es proveer un marco conceptual para dar un contexto al concepto de indicadores de calidad en salud y el rol que estos juegan en cirugía oncológica de cabeza y cuello. Se debe aspirar a lograr un mayor cumplimiento de los indicadores de calidad en cirugía oncológica de cabeza y cuello, especialmente en instituciones terciarias de referencia. Aplicar indicadores de calidad en el manejo oncológico en cabeza y cuello permitiría mejorar tanto la percepción y satisfacción del usuario, como también mejorar resultados oncológicos en estos pacientes.

Abstract Most health services have experienced an increase in the costs associated with health care, which has led to the adoption of measures to optimize the cost-effectiveness of the services provided. From this perspective, the concept of value-based health care emerged. The concept of "quality in health care" has been defined as the degree to which health services increase the possibility of generating certain desired health outcomes. Quality indicators are classified into structure, process, and outcome indicators. The structure indicators refer to the characteristics of the health system or the hospital institution. Process indicators refer to those that the health service provider performs for the health care process, while outcome indicators refer to the results of the process in the patient. The objective of this review is to provide a conceptual framework to give a context to the concept of health quality indicators and the role they play in head and neck surgical oncology. The system should aspire to achieve greater compliance with quality indicators in head and neck cancer surgery, especially in referral tertiary institutions. Applying quality indicators in head and neck cancer management would improve both user perception and satisfaction, as well as improve oncological results in these patients.

Abstract Introduction: Cutaneous basal cell carcinoma recurrence is associated with inadequate surgical margins. The frequency of and the factors associated with compromised or inadequate surgical margins in head and neck basal cell carcinoma varies. Objective: The purpose of this study was to evaluate the clinical and pathological factors associated with inadequate surgical margins in head and neck basal cell carcinoma. Methods: We developed a cross-sectional study comprising all patients who had undergone resection of head and neck basal cell carcinoma from January 2017 to December 2019. Data on age, sex, head and neck topography, histopathological findings, and staging were retrieved and compared. Each tumor was considered an individual case. Compromised and close margins were termed ''inadequate'' or ''incomplete''. Variables that were significantly associated with the presence of incomplete margins were further assessed by logistic regression. Results: In total, 605 tumors from 389 patients were included. Overall, sixteen cases (2.6%) were classified as compromised, 52 (8.5%) as close, and 537 (88.7%) as free margins. Presence of scleroderma (p = 0.005), higher Clark level (p < 0.001), aggressive variants (p < 0.001), invasion beyond the adipose tissue (p < 0.001), higher T stage (p < 0.001), perineural invasion (p = 0.002), primary site (p = 0.04), multifocality (p = 0.01), and tumor diameter (p = 0.02) showed association with inadequate margins. After Logist regression, multifocality, Clark level and depth of invasion were found to be independent risk factors for inadequate margins. Conclusion: Gross clinical examination may be sufficient for determining low prevalence of inadequate surgical margins when treating head and neck basal cell carcinoma in highly experienced oncologic centers. Multifocality, Clark level and depth of invasion were found to be independent risk factors for incomplete margins.

Resumo Introdução: A recorrência do carcinoma basocelular (CBC) cutâneo está associada a margens cirúrgicas inadequadas. A frequência e os fatores associados a margens cirúrgicas comprometidas ou inadequadas no carcinoma basocelular de cabeça e pescoço variam. Objetivo: Avaliar os fatores clínicos e patológicos associados a margens cirúrgicas inadequadas no carcinoma basocelular de cabeça e pescoço. Método: Conduzimos um estudo transversal que abrangeu todos os pacientes submetidos à resseçcão de carcinoma basocelular de cabeça e pescoço de janeiro de 2017 a dezembro de 2019. Dados sobre idade, sexo, topografia na cabeça e pescoço, achados histopatológicos e estadiamento foram recuperados e comparados. Cada tumor foi considerado como um caso individual. As margens comprometidas e próximas foram denominadas ''inadequadas'' ou ''incompletas''. As variáveis que foram significantemente associadas à presença de margens incompletas foram avaliadas adicionalmente por regressão logística. Resultados: Foram incluídos 605 tumores de 389 pacientes. No geral, 16 casos (2,6%) foram classificados como comprometidos, 52 (8,5%) como próximos e 537 (88,7%) como margens livres. Presença de esclerodermia (p = 0,005), nível de Clark mais elevado (p < 0,001), variantes agressivas (p < 0,001), invasão além do tecido adiposo (p < 0,001), estágio T mais avançado (p < 0,001), invasão perineural (p = 0,002), sítio primário (p = 0,04), multifocalidade (p = 0,01) e diâmetro do tumor (p = 0,02) mostraram associação com margens inadequadas. Após a regressão logística, a multifocalidade, o nível de Clark e a profundidade de invasão foram considerados fatores de risco independentes para margens inadequadas. Conclusão: O exame clínico macroscópico pode ser suficiente para determinar baixa prevalência de margens cirúrgicas inadequadas no tratamento do carcinoma basocelular de cabeça e pescoço em centros oncológicos altamente experientes. Multifocalidade, nível de Clark e profundidade de invasão foram considerados fatores de risco independentes para margens incompletas.

Abstract Introduction Regional metastases of cutaneous head and neck squamous cell carcinoma occur in approximately 5 % of cases, being the most important prognostic factor in survival, currently with no distinction between parotid and neck metastasis. Objective The purpose of this study was to evaluate the prognostic features among patients with head and neck cutaneous squamous cell carcinoma exhibiting regional metastasis. Methods A retrospective analysis of patients with cutaneous squamous cell carcinoma who underwent parotidectomy and/or neck dissection from 2011 to 2018 at a single institution tertiary center was performed. Patient demographics, clinical, surgical and pathological information, adjuvant treatments, and outcome at last follow-up were collected. Outcomes included disease recurrence and death due to the disease. Prognostic value of clinic pathological features associated with disease-specific survival was obtained. Results Thirty-eight cases of head and neck cutaneous squamous cell carcinoma with parotid and/or neck metastasis were identified. Overall, 18 (47.3 %) patients showed parotid metastasis alone, 12 (31.5 %) exhibited neck metastasis alone and 8 (21.0 %) had both. A primary tumor in the parotid zone (Hazard Ratio ‒ HR = 5.53; p = 0.02) was associated with improved disease-specific survival. Poorer disease-specific survival was observed in patients with higher primary tumor diameter (HR = 1.54; p = 0.002), higher depth of invasion (HR = 2.89; p = 0.02), invasion beyond the subcutaneous fat (HR = 5.05; p = 0.002), neck metastasis at first presentation (HR = 8.74; p < 0.001), number of positive lymph nodes (HR = 1.25; p = 0.004), and higher TNM stages (HR = 7.13; p = 0.009). Patients presenting with isolated parotid metastasis during all follow-ups had better disease-specific survival than those with neck metastasis or both (HR = 3.12; p = 0.02). Conclusion Head and neck cutaneous squamous cell carcinoma with parotid lymph node metastasis demonstrated better outcomes than cases with neck metastasis.

Resumo Introdução As metástases regionais do carcinoma espinocelular cutâneo de cabeça e pescoço ocorrem em aproximadamente 5% dos casos, sendo esse o fator prognóstico mais importante na sobrevida, atualmente sem distinção entre metástases de parótida e cervicais. Objetivo Avaliar as características prognósticas em pacientes com carcinoma espinocelular cutâneo de cabeça e pescoço com metástase regional. Método Foi feita uma análise retrospectiva de pacientes com carcinoma espinocelular cutâneo submetidos à parotidectomia e/ou esvaziamento cervical entre 2011 e 2018 em um único centro terciário de uma única instituição. Dados demográficos dos pacientes, informações clínicas, cirúrgicas e patológicas, tratamentos adjuvantes e desfechos no último acompanhamento foram coletados. Os desfechos incluíram recorrência e morte devido à doença. O valor prognóstico das características clínico-patológicas associadas à sobrevida específica da doença foi obtido. Resultados Foram identificados 38 casos de carcinoma espinocelular cutâneo de cabeça e pescoço com metástase de parótida e/ou pescoço. No geral, 18 (47,3%) pacientes apresentaram metástase da parótida isolada, 12 (31,5%) apresentaram metástase cervical isolada e 8 (21,0%) apresentaram ambos. Um tumor primário na região da parótida (Hazard ratio [HR] = 5,53; p = 0,02) foi associado a melhor sobrevida específica. Pior sobrevida específica foi observada em pacientes com maior diâmetro do tumor primário (HR = 1,54; p = 0,002), maior profundidade de invasão (HR = 2,89; p = 0,02), invasão além da gordura subcutânea (HR = 5,05; p = 0,002), metástase cervical na primeira apresentação (HR = 8,74; p < 0,001), conforme maior número de linfonodos positivos (HR = 1,25; p = 0,004) e estágios TNM mais elevados (HR = 7,13; p = 0,009). Os pacientes que apresentaram metástase da parótida isolada durante todo o acompanhamento apresentaram melhor sobrevida específica do que aqueles com metástase cervical ou ambos (HR = 3,12; p = 0,02). Conclusão Os casos de carcinoma espinocelular cutâneo de cabeça e pescoço com metástase intraparotídea demonstraram melhores desfechos do que aqueles com metástase cervical.

Antecedentes: el tratamiento del CBC con menor tasa de recurrencia es el quirúrgico. Debido a la ausencia de lesión residual en cirugía de ampliación de márgenes y la utilidad de la congelación intraoperatoria se propuso analizar la utilidad de las retomas intraoperatorias. Objetivo: analizar el impacto de las retomas intraoperatorias en los resultados oncológicos y cosméticos de los pacientes operados de CBC. Secundariamente analizar la extensión subclínica, el valor de la congelación intraoperatoria y las tácticas reconstructivas empleadas. Lugar de aplicación: Hospital de atención terciaria de tumores. Material y métodos: trabajo observacional retrospectivo. Se incluyeron 84 resecciones durante 3 años y se realizó un análisis comparativo en términos de recurrencia, defecto quirúrgico y utilización de colgajos entre tumores sin retoma vs con retoma. Resultados: no hubo diferencias significativas en cuanto a recurrencia y uso de colgajos. El promedio de defecto para los tumores retomados fue 27,8mm y para los no retomados 22,8mm, siendo la diferencia estadísticamente significativa (p=0.002). En el subgrupo de lesiones retomadas se encontró tumor residual en solo 2,9% de las mismas. Conclusiones: las retomas adicionaron en promedio 5mm de defecto por lesión sin aportar beneficios en términos de recurrencia. Un uso más conservador de las mismas podría traducirse en mejores resultados funcionales y cosméticos

Background: the lowest recurrence rates for basal cell carcinoma are achieved by surgical treatment. Low rates of residual tumour in specimens after incomplete excisions plus intraoperative frozen section accuracy are the rationale for analyzing the value of intraoperative re-excisions during basal cell carcinoma standard surgery. Objective: to analyse intraoperative oncologic and cosmetic results of re-captures in patients surgically treated of basal-cells carcinoma. Secondary to analyse subclinic extention, the value of frozen intraoperative sections and reconstructive conducts employed. Setting: tertiary care Hospital of tumours. Methods: observational retrospective study. During a 3-year period 84 tumours were resected. A comparative analysis in terms of recurrence, surgical defect and use of flaps was done between intraoperatively re-excised and not re-excised tumours. Results: there were no statistical difference regarding recurrence rate and use of flaps. Mean surgical defect for re-excised and not re-excised specimens was 27,8mm and 22,8mm respectively, being the difference statistically significant (p=0.002). Residual tumour was found in only 2,9% of re-excised specimens. Conclusions: re-excisions added on average 5mm to surgical defect per specimen and did not contribute to any benefit in terms of recurrence rates. A more conservative use of intraoperative re-excisions could improve functional and cosmetic outcomes

El hemangioma fusocelular es una neoplasia vascular benigna infrecuente. Afecta la dermis y la hipodermis de la parte distal de las extremidades; la afectación de la cabeza y el cuello es muy poco frecuente y nunca se informó compromiso de los senos paranasales. Este es el caso de un lactante de 4 meses con obstrucción nasal desde las 2 semanas debido a un tumor en los senos etmoidales que obstruía las fosas nasales. Se diagnosticó hemangioma fusocelular y se extirpó parcialmente el tumor. A los seis meses de seguimiento, se observó una regresión mínima con lesiones residuales. A los 30 meses, se observó que el tumor residual había desaparecido. El hemangioma fusocelular es infrecuente en cabeza y cuello y, a veces, la presentación no es indicativa del diagnóstico. El examen histopatológico ayuda con el diagnóstico diferencial y el tratamiento. La sensibilización sobre el hemangioma fusocelular podría aumentar los casos informados.

Spindle cell hemangioma (SCH) is a benign unusual vascular neoplasm. It does not have gender predilection and can occur at all ages. The disease affects dermis and subcutis of distal extremities predominantly; head and neck involvement is very rare, paranasal sinus involvement has not been reported before. Herein we present a 4-month-old infant with nasal obstruction since two weeks of age due to a mass in ethmoid sinus obliterating the nasal passage. After the histopathological diagnosis of SCH, the tumor was partially resected. In the sixth month follow-up, there was minimal regression of residual lesions. In the imaging studies performed 30 months after the surgery, the residual mass was found to be disappeared. SCH is not frequent in the head and neck, and presentation of some patients may not suggest the diagnosis. Histopathology is important for differential diagnosis and to orientate treatment. Awareness of SCH may increase the reported cases

Abstract Introduction: Sentinel lymph node biopsy is the gold standard procedure for head and neck cutaneous melanoma staging. Objective: To evaluate the technical aspects, positivity and prognostic effect of the cervico-facial sentinel lymph node biopsy. Methods: Retrospective, unicentric study. From 2009 to 2014, 49 patients with cutaneous melanoma of the head and neck underwent surgery at Instituto do Câncer do Estado de São Paulo (ICESP). Results: Of the 49 patients, 5 had cervical metastasis at the moment of admission. Clark, Breslow and mitotic index were predictors of death. Among the 31 patients undergoing sentinel lymph node biopsy, 3 had positive sentinel lymph nodes (9.7%). Deaths were recorded in two of the cases with positive sentinel lymph nodes (66.6%), and in 5 (17.8%) of the patients with negative lymph nodes. The mean Breslow index was 11.3 mm for primary melanomas with positive sentinel lymph nodes and 4.3 mm for those with negative sentinel lymph nodes. Positivity was associated with Clark and Breslow levels. Malar location showed a protective effect on prognosis. The mean survival for patients with a mitotic index <3.5 was 181 months and 63.4 months for those with a mitotic index >3.5. Conclusion: The frequency of positive sentinel lymph node biopsy in patients with malignant melanoma of the head and neck was lower than in other studies, although the sample consisted of individuals with advanced melanomas. The mitotic index was important for prognosis prediction.

Resumo Introdução: A biópsia de linfonodo sentinela é o padrão-ouro para estadiamento de melanomas cutâneos em cabeça e pescoço. Objetivo: Avaliar aspectos técnicos, positividade e efeito prognóstico da pesquisa de linfonodo sentinela cervico-facial. Método: Estudo retrospectivo, unicêntrico. Entre 2009 e 2014, 49 pacientes com melanoma cutâneo de cabeça e pescoço foram operados no Instituto do Câncer do Estado de São Paulo (ICESP). Resultado: Dos 49 pacientes, cinco tiveram metástases cervicais detectáveis à admissão. Níveis de Clark e Breslow e índice mitótico foram preditores de risco de óbito. Entre os 31 pacientes submetidos à biópsia de linfonodo sentinela, três tiveram resultados positivos (9,7%). Faleceram dois (66,6%) dos portadores de micrometástases e cinco (17,8%) entre os pacientes com linfonodos sentinela negativos. A média do índice de Breslow foi de 11,3 mm entre os casos positivos e 4,3 mm nos negativos. A positividade foi associada aos níveis de Clark e Breslow. A localização malar teve efeito protetor. A média de tempo de sobrevivência dos pacientes com índice mitótico abaixo de 3,5 foi de 181 meses e para aqueles com índice mitótico acima de 3,5 foi de 63,4 meses. Conclusão: A frequência de linfonodo sentinela positivo foi mais baixa do que a encontrada em outros estudos, apesar de a amostra ter sido composta por melanomas avançados. O índice mitótico foi importante na predição de prognóstico.

Abstract Background and objectives: In this study, we aimed to investigate the predictive value of different airway assessment tools, including parts of the Simplified Predictive Intubation Difficulty Score (SPIDS), the SPIDS itself and the Thyromental Height Test (TMHT), in intubations defined as difficult by the Intubation Difficulty Score (IDS) in a group of patients who have head and neck pathologies. Methods: One hundred fifty-three patients who underwent head and neck surgeries were included in the study. The Modified Mallampati Test (MMT) result, Thyromental Distance (TMD), Ratio of the Height/Thyromental Distance (RHTMD), TMHT, maximum range of head and neck motion and mouth opening were measured. The SPIDSs were calculated, and the IDSs were determined. Results: A total of 25.4% of the patients had difficult intubations. SPIDS scores >10 had 86.27% sensitivity, 71.57% specificity and 91.2% Negative Predictive Value (NPV). The results of the Receiver Operating Curve (ROC) analysis for the airway screening tests and SPIDS revealed that the SPIDS had the highest area under the curve; however, it was statistically similar to other tests, except for the MMT. Conclusions: The current study demonstrates the practical use of the SPIDS in predicting intubation difficulty in patients with head and neck pathologies. The performance of the SPIDS in predicting airway difficulty was found to be as efficient as those of the other tests evaluated in this study. The SPIDS may be considered a comprehensive, detailed tool for predicting airway difficulty.

Resumo Justificativa e objetivos: Neste estudo, avaliamos o valor preditivo de diferentes ferramentas de avaliação das vias aéreas, incluindo componentes do Escore Simplificado Preditivo de Intubação Difícil (ESPID), o próprio ESPID e a Medida da Altura Tireomentoniana (MATM), em intubações definidas como difícies pelo Escore de Dificuldade de Intubação (EDI) em um grupo de pacientes com patologia de cabeça e pescoço. Método: Incluímos no estudo 153 pacientes submetidos a cirurgia de cabeça e pescoço. Coletamos os resultados do Teste de Mallampati Modificado (TMM), Distância Tireomentoniana (DTM), Razão Altura/Distância Tireomentoniana (RADTM), MATM, amplitude máxima de movimentação da cabeça e pescoço e da abertura da boca. Os ESPIDs foram calculados e os EDIs, determinados. Resultados: Observamos intubação difícil em 25,4% dos pacientes. Os escores de ESPID > 10 tiveram sensibilidade de 86,27%, especificidade de 71,57% e valor preditivo negativo de 91,2% (VPN). O resultado da análise da curva de operação do receptor (curva ROC) para os testes de avaliação das vias aéreas e ESPID mostrou que o ESPID tinha a maior área sob a curva; no entanto, foi estatisticamente semelhante a outros testes, exceto para o TMM. Conclusões: O presente estudo demonstra o uso prático do ESPID na previsão da dificuldade de intubação em pacientes com patologia de cabeça e pescoço. O desempenho do ESPID na predição de via aérea difícil mostrou-se tão eficiente quanto os demais testes avaliados neste estudo. O ESPID pode ser considerado ferramenta abrangente e detalhada para prever via aérea difícil.

El neuroblastoma es uno de los tumores sólidos extracraneales más comunes en la edad pediátrica, y se origina en células precursoras del sistema nervioso simpático. La ubicación cervical corresponde a un 2-5% del total de los neuroblastomas y puede tener distintas manifestaciones clínicas, tales como masa cervical, disnea, estridor, síndrome de Horner o disfagia. Esta entidad debe ser considerada dentro del diagnóstico diferencial de una masa cervical pediátrica, especialmente ante la presencia de masas sólidas, laterales o paramedianas, palpables o no al examen físico. El tratamiento específico del neuroblastoma depende de la clasificación de riesgo del paciente, pudiendo ser expectante en casos específicos, exclusivamente quirúrgico, o bien requerir complementarse con otras terapias. En este artículo se presentan 2 casos clínicos de pacientes pediátricos con neuroblastoma cervical tratados de forma exclusiva y exitosa con cirugía, y una revisión del tema.

Neuroblastoma is one of the commonest extracranial solid tumors at pediatric age, originating from sympathetic nervous system precursor cells. Cervical position stands for 2-5% of all neuroblastomas, with variable clinical expression that includes cervical mass, dyspnea, stridor, Horner syndrome and dysphagia. This condition must be considered in the differential diagnosis of a pediatric cervical mass, specially in those solid, lateral/paramedian masses that could be palpable or not at physical examination. The specific treatment in neuroblastoma depends on patient´s risk group, including conservative follow-up in selected cases, surgery alone, or complementary perioperative therapy with chemotherapy and others. In this article, the group report two cases of cervical neuroblastoma exclusively treated with surgery with good results, and a literature review.

Abstract Background: High-risk basal cell carcinoma involves a significant rate of basal cell carcinoma that requires Mohs micrographic surgery for definitive treatment. Staged excision with pathologic margin control is a simple, accessible, and curative procedure suggested for the treatment of high-risk basal cell carcinoma. Objective: To evaluate the results of staged excision of high-risk basal cell carcinoma in the head region. Methods: This interventional study was performed on patients with high-risk basal cell carcinoma, who underwent staged excision until the margins were free of tumor. Results: A total of 122 patients (47 females and 75 males) with mean age of 57.66 ± 9.13 years were recruited in this study. Nasal and nodular types were the most common of both clinical and pathologic forms, respectively. Further, 89.3 % of cases were cured by staged excision after four years of follow-up. There was a significant relationship between treatment outcomes and recurrent lesions, multiplicity of risk factors, long-standing disease, and pathologic type. There was also a significant association between the number of surgical excisions and multiplicity of risk factors, as well as recurrence, location, and size of basal cell carcinoma. Study limitations: Lack of magnetic resonance imaging assessment in cases of suspected perineural invasion. Conclusions: High-risk basal cell carcinoma had a high cure rate by staged excision. Patients with more risk factors and those with nasal and recurrent basal cell carcinoma required more staged excisions. Failure of treatment is more probable in patients with more risk factors, long-standing lesions, and high-risk pathologic and recurrent basal cell carcinomas.
