Colgajo libre antebraquial radial para reconstrucción microvascular en cáncer de cavidad oral localmente avanzado. Reporte de caso

Introducción: El cáncer de cavidad oral es la malignidad más frecuente dentro de los tumores de cabeza y cuello. El tratamiento estándar curativo corresponde a la cirugía radical cuyo resultado puede impactar de manera significativa la función y morfología del subsitio resecado. La transferencia de colgajos libres mediante técnicas quirúrgicas microvasculares permite expandir la capacidad de resección oncológica de manera segura con adecuada tasa de éxito limitando las secuelas. Caso clínico: Varón de 48 años con cáncer de lengua oral localmente avanzado tratado quirúrgicamente con hemiglosectomía izquierda extendida, disección ganglionar cervical bilateral y reconstrucción microvascularizada con un colgajo libre antebraquial radial. Discusión: Entre un 30% a 35% de las neoplasias de cavidad oral se presentan como enfermedad localmente avanzada. La reconstrucción intraoral suele ser un reto. La planificación quirúrgica del defecto anatómico y funcional son importantes para elegir la opción de reconstrucción y valorar el riesgo de complicaciones posoperatorias. Conclusión: La utilización de colgajos microvasculares libres en la reconstrucción oncológica es fundamental para restaurar el volumen y función de los tejidos afectados por la resección radical. El colgajo libre antebraquial radial es una herramienta versátil debido a sus características físicas y baja tasa de complicaciones en el sitio donante. (provisto por Infomedic International)

Introduction: Oral cavity cancer is the most frequent malignancy within head and neck tumors. The standard curative treatment corresponds to radical surgery whose outcome can significantly impact the function and morphology of the resected subsite. The transfer of free flaps by means of microvascular surgical techniques allows to expand the capacity of oncologic resection in a safe way with an adequate success rate limiting the sequelae. Case report: 48-year-old male with locally advanced oral tongue cancer treated surgically with extended left hemi glossectomy, bilateral cervical lymph node dissection and micro vascularized reconstruction with a radial antebrachial free flap. Discussion: 30% to 35% of oral cavity neoplasms present as locally advanced disease. Intraoral reconstruction is often a challenge. Surgical planning of the anatomic and functional defect are important in choosing the reconstruction option and assessing the risk of postoperative complications. Conclusion: The use of microvascular free flaps in oncologic reconstruction is essential to restore the volume and function of tissues affected by radical resection. The radial antebrachial free flap is a versatile tool due to its physical characteristics and low rate of complications at the donor site. (provided by Infomedic International)

Twenty four years of oral and maxillofacial surgery malpractice claims in Spain: patient safety lessons to learn.

PURPOSE: Oral and maxillofacial surgery (OMS) malpractice risk is of special interest due to both the aesthetic component of some procedures and the complexity of the pathologies involved. This study aims to identify relevant factors involved in OMS professional liability (PL) claims to help achive better management of risks and improve patient safety. METHODS: We performed a retrospective analysis of 315 OMS claims opened between 1990 and 2014 from the database of the PL Department of the Catalonian Council of Medical Colleges, and identified their clinical, economical and juridical characteristics. RESULTS: OMS showed a high rate of compensation (33.8%). Dental implant surgery, third molar surgery and rhinoplasty presented the greatest exposure to claims, and in these cases, lack of osteointegration of dental implants, neurologic injury of inferior dentoalveolar/lingual nerves and a poor aesthetic result were the most frequently compensated sequelae. Statistically, significant association was found between this perioperative complications group and the presence of PL. Poorly documented patient information (informed consent document) was also significantly related with PL outcome. CONCLUSIONS: OMS is a specialty of medium risk for claims, especially oral surgery cases. Surgical complications, such as neurologic damage after oral/head and neck procedures and poor aesthetic results, do occur and deserve special attention to improve patient safety, as well as patient-information procedure.

Locally destructive mandibular pseudotumor as a manifestation of immunoglobulin G4-related disease.

Immunoglobulin G4-related disease is a recently identified entity. The cervicofacial location is not frequent. We report the case of a patient with an inflammatory pseudotumor in the mandible, who had to undergo surgery for diagnosis. We review the clinical manifestations, diagnostic criteria, differential diagnosis, and treatment proposed by recent publications in the literature. This case report represents the first case located in the mandible and the second one with bone destruction.

Metástasis parotídea de un carcinoma renal: A propósito de un caso / Parotid metastasis of renal carcinoma: a case report

En la literatura indexada, solo se han descrito 29 pacientes desde 1986. La aparición de metástasis de un carcinoma renal a nivel parotídeo es un fenómeno poco frecuente. Presentamos un paciente de 61 años, que tras cinco años de la realización de una nefrectomía unilateral por un carcinoma renal de células claras, desarrolló una metástasis de localización parotídea(AU)

Metastastic spread of renal cell carcinoma to the parotid gland is rare. In the indexed literature, with only 29 patients recorded since 1986. The case of a 61-year-old patient who developed parotid metastasis of renal cell carcinoma five years after unilateral nephrectomy is reported(AU)

Sarcomas mandibulares: experiencia quirúrgica en los últimos 10 años / Mandibular sarcomas: surgical experience over the past 10 years

Introducción: Los sarcomas mandibulares representan una entidad de difícil estudio por su escasa incidencia e histopatología. Pacientes y métodos: Presentamos la experiencia del servicio de Cirugía Oral y Maxilofacial del Hospital Vall d’Hebron de Barcelona en los últimos 10 años (2001-2010) en el manejo de los sarcomas mandibulares, realizando una revisión retrospectiva de 12 casos de pacientes afectos por este tipo de tumor. Resultados: La técnica más utilizada para la reconstrucción fue el colgajo microvascularizado (hueso peroné: 8/12), recibiendo tratamiento adyuvante (quimioterapia y/o radioterapia) el 82% de los pacientes. Cinco pacientes fallecieron (42%), 2 se encuentran con progresión de la enfermedad (16%) y 5 sobreviven libres de enfermedad (42%) hasta la finalización del seguimiento. Conclusiones: Los casos descritos representan una serie singular debido a la localización mandibular, no antes publicadas en la literatura. Aún así, los resultados obtenidos en términos de supervivencia y factores pronóstico son similares a los descritos para los sarcomas de cabeza y cuello. La consecución de márgenes libres con la cirugía es la clave del tratamiento, siendo necesario el tratamiento complementario para mejorar el pronóstico(AU)

Introduction: Sarcomas located in the mandible are difficult to study due to their relatively rare appearance and histology. Patients and Methods: We present the experience of the Oral and Maxillofacial Surgery Department of the Vall d’Hebron Hospital in Barcelona over the last 10 years (2001-2010) in the management of jaw sarcomas, performing a retrospective review of 12 cases of patients affected by this type of tumour. Results: The technique mostly used for the reconstruction was the microvascularised bone graft (fibula: 8/12), with 82% of the patients receiving adjuvant therapy (chemotherapy and radiotherapy). Five of the patients died (42%), twowere found with disease progression (16%), and 5 survived free of disease (42%) until the end of follow-up. Conclusions: The cases described are a unique series due to the mandibular location. Prognostic factors and survival rates are similar to those described for head and neck sarcomas. Free margin during surgery must be the goal of treatment, additional chemotherapy or radiotherapy or both being required to improve the survival rates(AU)
