Outcomes and survival of tracheostomised patients during the COVID-19 pandemic in a third level hospital.

PURPOSE: Analyse the evolution and outcomes of COVID-19 tracheostomised patients. Clarify if this cohort presents an increased risk of haemorrhagic complications and verify the correlation between some risk factors with increased mortality. METHODS: A retrospective single-centre observational study of a prospective cohort of all COVID-19 patients admitted to our centre between March and April 2020. A control group was obtained from a historical cohort of patients who required tracheostomy due to prolonged invasive mechanical ventilation (IMV) before 2020. RESULTS: A total of 1768 patients were included: 67 tracheostomised non-COVID-19 patients (historic cohort), 1371 COVID-19 patients that did not require ICU admission, 266 non-tracheostomised COVID-19 patients and 64 tracheostomised COVID-19 patients. Comparing the obesity prevalence, 54.69% of the tracheostomised COVID-19 patients were obese and 10.53% of the non-tracheostomised COVID-19 patients (p < 0.001). The median of ICU admission days was lower (p < 0.001) in the non-tracheostomised cohort (12.5 days) compared with the COVID-19 tracheostomised cohort (34 days). The incidence of haemorrhagic complications was significantly higher in tracheostomised COVID-19 patients (20.31%) compared with tracheostomised non-COVID-19 patients (5.97%) and presented a higher percentage of obesity, hypertension, diabetes and smoking, significantly different from the historic cohort (p < 0.001). A Cox model showed that tracheostomy had no statistically significant effect on mortality in COVID-19 patients. CONCLUSION: Obesity and smoking may be risk factors for tracheostomy in COVID-19 patients, tracheostomised COVID-19 patients present a higher risk of bleeding complications than those admitted for other reasons and an elevated LDH and INR on ICU admission may be associated with increased mortality.

Colgajo antebraquial radial en cabeza y cuello: nuestra experiencia / Free radial forearm flap in head and neck: our experience

Introducción: La cirugía oncológica conlleva a importantes defectos y secuelas, así como alteraciones funcionales y cosméticas notables. En este aspecto, la cirugía reconstructiva tiene un papel esencial, permitiendo mayor radicalidad en la exéresis y disminución de las morbilidades funcionales y cosméticas asociadas. El objetivo de este estudio es presentar y evaluar la experiencia y resultados de la Unidad de Microcirugía Reconstructiva del Servicio de Otorrinolaringología de nuestro centro. Métodos: Estudio retrospectivo de procedimientos realizado entre los años 2006-2012. Resultados: Un total de 36 casos fueron revisados. El tumor primario se localizó en la mayoría de los casos en orofaringe (58%). En 5 casos se realizó el procedimiento para reconstrucción y cierre de fístulas (4 faringostomas y una fístula traqueoesofágica). El fracaso por necrosis total fue del 16% (6/39). No se produjo mortalidad asociada. Las complicaciones postoperatorias más frecuentes fueron: dehiscencia de sutura en 5 pacientes y faringostoma (fístula) en 5 casos. La radioterapia previa influyó de forma significativa en el aumento de la incidencia global de las complicaciones (p < 0,05). Conclusiones: Actualmente, la cirugía reconstructiva juega un papel fundamental en la cirugía oncológica de cabeza y cuello. El colgajo radial es un método seguro y fiable para la reconstrucción de la mayoría de defectos en la esfera otorrinolaringológica. Asumir este tipo de intervención ofrece una mayor autonomía y seguridad en la cirugía oncológica (AU)

Introduction: Oncologic surgery leads to important defects and sequelae, as well as notable cosmetic and functional alterations. In this aspect reconstructive surgery has an essential role, allowing more radical excision and lower associated functional and cosmetic morbidities. The aim of this study was to present and evaluate the experience and results of the reconstructive microsurgery unit in our centre's ENT department. Methods: Retrospective study of procedures performed between 2006 and 2012. Results: A total of 36 cases were reviewed. The primary tumour was found in the oropharynx (58%) in the majority of cases. In 5 cases the procedure was performed for reconstruction and fistula closure (4 pharyngostoma and 1 tracheoesophageal fistula). Failure from total necrosis was 16% (6/36). No associated mortality has been reported. The most common postoperative complications were wound dehiscence in 5 patients and pharyngostoma (fistula) in 5 cases. Prior radiotherapy significantly influenced the increase in the overall incidence of complications (P<0.05). Conclusions: Reconstructive surgery currently plays an important role in surgery for head and neck cancer. The radial forearm flap is a safe, reliable method for reconstruction of most defects in the ENT field. This type of intervention provides greater autonomy and safety in surgical oncology (AU)

Resultados en el tratamiento quirúrgico de los neurinomas del acústico gigantes / Results in the surgical treatment of giant acoustic neuromas

Introducción y objetivos: Comparar los resultados obtenidos en la resección de 21 schwanomas vestibulares gigantes, mediante vía retrosigmoidea y combinada retrosigmoidea/translaberíntica en cuanto a complicaciones intra y postoperatorias, preservación del nervio facial y secuelas posquirúrgicas. Métodos: Se realiza un estudio retrospectivo de 21 pacientes a los que se practicó resección de neurinoma vestibular gigante según la escala de Tos & Thomsen (igual o mayor a 4cm), en un hospital de tercer nivel en el periodo entre 2000 y 2008. Se presentan las características más significativas de la serie estudiada, y se analizan las ventajas e inconvenientes de los distintos abordajes, comparando los resultados obtenidos. Asimismo, se analizan los resultados en cuanto a la preservación de la función del nervio facial. Resultados: Destaca la ausencia de mortalidad en el grupo de 21 pacientes estudiado. No hubo complicaciones intraoperatorias importantes. Se consiguió la resección total de la lesión en el 87% de los casos, con una preservación anatómica del nervio facial del 73% en el abordaje combinado retrosigmoideo/translaberíntico, respecto a un 40% en el retrosigmoideo. La función del nervio facial a los dos años fue aceptable o buena en un 67% (incluyendo los resultados de las anastomosis heteronerviosas). Se observó un porcentaje global del 14,3% de fístula de líquido cefalorraquídeo y un 9,5% de meningitis. Conclusiones: nuestros resultados demuestran que el abordaje combinado retrosigmoideo translaberíntico para el tratamiento de schwannomas gigantes ofrece mayor preservación del nervio facial y disminución de la morbilidad, siendo una importante opción en el tratamiento de estos tumores, gracias a un enfoque multidisciplinar(AU)

Introduction and objectives: To compare the results obtained in the resection of 21 giant vestibular schwannomas via retrosigmoid (RS) and combined retrosigmoid/translabyrinthine (RS/TL) approaches with respect to intra- and postoperative complications, facial nerve preservation and postsurgical sequelae. Methods: This was a retrospective study of 21 patients who underwent a resection of a giant vestibular neuroma according to the Tos & Thomsen Scale (greater than or equal to 4 centimetres) in a tertiary care centre in the period between 2000 and 2008. We present the most significant characteristics of the series studied and the analysis of the advantages and inconveniences of each approach. We also analyse the results regarding facial nerve function preservation. Results: We highlight the absence of mortality in the 21-patient group. There were no important intraoperative complications. Total resection of the lesion was achieved in the 87% of the cases, with facial nerve preservation of 73% using the combined RS/TL approach, in comparison to 40% using the RS. Facial nerve function after two years was acceptable or good in 67% (including those with heteronerve anastomosis). A global percentage of 14.3% of cerebrospinal liquid fistula was observed, as well as 9.5% of meningitis. Conclusions: The results of the study demonstrate that the combined retrosigmoid translabyrinthine approach for giant schwannoma treatment offers increased facial nerve preservation and lower morbidity, constituting an important option in the treatment of this kind of tumours thanks to a multidisciplinary approach(AU)
