Nuestra experiencia con la monitorización del nervio facial en cirugía del schwannoma del vestibular bajo bloqueo neuromuscular parcial / Our experience with facial nerve monitoring in vestibular schwannoma surgery under partial neuromuscular blockade

Introducción y objetivos: La monitorización del nervio facial es fundamental en la preservación del nervio facial en la cirugía del schwannoma del nervio vestibular. Nuestro objetivo es analizar la utilidad de la monitorización facial bajo bloqueo neuromuscular parcial. Métodos: Análisis retrospectivo de 69 pacientes operados en un hospital de nivel terciario. Resultados: En el 100% de los casos se pudo realizar monitorización electromiográfica. Se obtuvo respuesta electromiográfica tras la escisión tumoral en el 75% de los casos. En 17 casos no hubo respuesta electromiográfica. En 15 hubo lesión de continuidad del nervio facial y en 2 hubo lesión pero se logró mantener la continuidad anatómica del nervio. La presencia de parálisis facial preoperatoria (29 vs. 7%; p = 0,0349), el mayor tamaño tumoral (88 vs. 38%; p = 0,0276) y una audición no funcional (88 vs. 51%; p = 0,0276) son factores significativamente más prevalentes en el grupo en que no se pudo obtener una respuesta electromiográfica. Conclusiones: La monitorización del nervio facial bajo bloqueo neuromuscular moderado es factible y segura en pacientes sin lesión facial preoperatoria. Los pacientes que obtienen respuesta electromiográfica tras la extirpación del tumor tienen mejor función facial en el postoperatorio y al año de seguimiento (AU)

Introduction and objectives: Facial nerve monitoring is fundamental in the preservation of the facial nerve in vestibular schwannoma surgery. Our objective was to analyse the usefulness of facial nerve monitoring under partial neuromuscular blockade. Methods: This was a retrospective analysis of 69 patients operated in a tertiary hospital. Results: We monitored 100% of the cases. In 75% of the cases, we could measure an electromyographic response after tumour resection. In 17 cases, there was an absence of electromyographic response. Fifteen of them had an anatomic lesion with loss of continuity of the facial nerve and, in 2 cases, there was a lesion with preservation of the nerve. Preoperative facial palsy (29% 7%; P=.0349), large tumour size (88 vs. 38%; P=.0276), and a non-functional audition (88 vs. 51%; P=.0276) were significantly related with an absence of electromyographic response. Conclusions: Facial nerve monitoring under neuromuscular blockade is possible and safe in patients without previous facial palsy. If the patient had an electromyographic response after tumour excision, they developed better facial function in the postoperative period and after a year of follow up (AU)

Cirugía reparadora de la parálisis facial mediante colgajo libre microvascularizado de músculo gracilis / Facial reanimation surgery with micro-vascular gracilis free flap for unilateral facial palsy

Introducción/objetivos: La transferencia de colgajo libre muscular microneurovascular es actualmente el procedimiento de elección para la parálisis facial de larga evolución. Presentamos una serie de casos de pacientes tratados con colgajo libre de músculo gracilis con inervación motora por el nervio maseterino. Se analiza la técnica quirúrgica y cuantificamos el movimiento otorgado por el músculo, así como la mejoría en la calidad de vida y los resultados estéticos obtenidos. Materiales y métodos: Se analizan 10 pacientes con parálisis facial unilateral, quienes fueron intervenidos con colgajo muscular libre gracilis, durante los años 2010 y 2012 en 2 centros hospitalarios de tercer nivel. Resultados: No encontramos fallo de la microsutura con supervivencia de todos los colgajos realizados. El movimiento muscular se cuantificó mediante vectores en reposo y contracción, con un promedio de 1,7 cm, se inició aproximadamente hacia el cuarto mes después de la intervención. Se demuestra también una mejoría significativa de la simetría en reposo, así como de la competencia oral y ocular. Conclusiones: Como se presenta actualmente en la literatura los colgajos libres microvascularizados son la técnica de elección para la reanimación facial. En nuestra experiencia consideramos que el colgajo con músculo gracilis inervado por el nervio maseterino es una técnica fiable y segura, que ofrece adecuados resultados tanto funcionales como estéticos (AU)

Introduction and objectives: Micro-neurovascular free muscle flap transfer is currently the procedure of choice for long-standing facial paralysis. We present a case series of patients treated with gracilis muscle free flap with motor innervation by the masseteric nerve. We discuss the surgical technique and quantify the movement granted by the muscle, the improvement in quality of life and aesthetic results. Materials and methods: We report ten patients with unilateral facial paralysis who underwent free gracilis muscle flap, between the years 2010 and 2012 in two tertiary hospitals. Results: It is not reported any failure of the microsuture with survival of all flaps. The muscle movement was quantified by vectors at rest and contraction with an average of 1.7 cm that initiated around the fourth month after surgery. Patients also reported a significant improvement in symmetry at rest as well as oral and ocular competition. Conclusion: As currently presented in literature, microvascular free flaps are the technique of choice for facial reanimation. In our experience, we believe that gracilis muscle flap innervated by the masseteric nerve is a reliable and secure technique that provides adequate functional and aesthetic results (AU)

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)
