Preservación de la glándula submandibular en las disecciones linfonodulares de cuello

Abstract: Introduccion: El desarrollo acelerado de la Oncologia ha condicionado recientes modificaciones terapeuticas que pudieran incluir la preservacion de la glandula submandibular en las disecciones de cuello. Objetivos : identificar los criterios para preservar quirurgicamente la glandula submandibular y exponer los fundamentos cientifico-teoricos que permitan plantear una modificacion actual a la tecnica de diseccion de cuello al conservar dicha glandula. Metodo : se realizo una busqueda exhaustiva retrospectiva de articulos publicados en las bases de datos electronicas PUBMED, MEDLINE, COCHRANE e HINARI desde Enero 2009 hasta Julio de 2014; en las revistas Head and Neck , Otolaryngology and Head and Neck Surgery y The Laryngoscope c on los terminos: “preservacion glandula submandibular”, “criterios oncologicos conservar glandula submandibular”, “modificaciones disecciones linfonodulares cervicales”, sin restricciones idiomaticas. Ademas de cumplir con estos requisitos se incluyeron solo los articulos cuyo material y metodo reflejara: estudios poblacionales, disecciones de cuello como tratamiento oncoespecifico y confirmacion anatomo-patologica para concluir el diagnostico. Fecha de publicacion: ultimos 5 anos. Resultados : de 3 estudios que conformaron una meta-poblacion de 829 pacientes, donde se preservo la glandula submandibular en un grupo de pacientes con tumores de cavidad bucal y orofaringe y disecciones de cuello simultaneas, se evidencio que no hubo diferencias en cuanto a recaida local, regional, a distancia ni sobrevida al compararlos con otro grupo de pacientes donde la diseccion de cuello no incluyo este proceder. Conclusion : los estudios coinciden en el bajo riesgo de metastasis ocultas a la glandula por carcinomas escamosos de cabeza y cuello, xerostomia post-quirurgica y factibilidad de la tecnica quirurgica como fundamentos para preservar la submandibular, de igual manera en que la ausencia de terapia oncoespecifica anterior, linfonodulos positivos en el subnivel IB y relacion entre el tumor primario y la glandula son criterios necesarios en la seleccion de candidatos para llevar a cabo este proceder.

Dientes supernumerarios y retención múltiple. Revisión de la literatura y presentación de un paciente

Abstract: Supernumerary teeth are additional teeth that develop in the jaws and they are rare in the population; cases with multiple supernumerary teeth are much more unusual. In the anterosuperior sector, when they are not erupted, they are frequent cause of alterations of the eruption of permanent teeth. The diagnosis and treatment of these pieces is necessary to avoid posterior complications that could alter the dental arch. It is presented a 13-year-old male patient referred to the Maxillofacial Surgery Consultation of “Arnaldo Milian Castro” Hospital because of an increase of volume in the anterior maxillary region and a delay in the outbreak of the central incisor and the canine on that side. Radiographic examination provided the presumptive diagnosis of supernumerary teeth. Surgical treatment, excision of the supernumerary teeth, placement of orthodontic traction devices to retained teeth and definitive orthodontic treatment were performed.

Metastasis to the submandibular gland in head and neck squamous cell carcinomas: Myth or reality?

Abstract: Introduction: very few studies have been published about the possibility of metastasis to the submandibular gland in head and neck squamous cell carcinomas. Objective: identify the latest scientific evidence about the possibility of metastasis to the submandibular gland in head and neck squamous cell carcinomas. Methods: a meta-analytical study was conducted based on a retrospective search of papers published in the databases PUBMED, MEDLINE, COCHRANE and HINARI from 2003 to 2013, as well as in the journals Acta of Otolaryngology, Journal of Otolaryngology, Journal of Laryngology and Otology, Journal of Cranio-Maxillo Surgery, International Journal of Oral and Maxillofacial Surgery, Head and Neck, and Annals of Surgical Oncology, using the following search terms: "metastasis from head and neck squamous cell carcinomas", "metastasis to salivary glands", "metastasis to the submandibular gland" and "malignant tumors of the submandibular gland", without any language restrictions. Papers were selected which met the above criteria and referred to the following contents in their materials and methods section: cervical lymph node surgery and dissection as the first onco-specific treatment, anatomopathological study to complete the Rev Cubana Estomatol. 2015;52(3) Organo Oficial de la Sociedad Cubana de Estomatologia ISSN-1561-297X

Is it necessary to remove submandibular glands in squamous cell carcinomas of the oral cavity? È necessaria l'asportazione chirurgica delle ghiandole sottomandibolari nel carcinoma squamoso del cavo orale?

Abstract: SUMMAry The aim of this study was to determine the frequency and the mechanism of submandibular gland (SMg) involvement in oral cavity squamous cell carcinomas (oCSCC), and to discuss the necessity of extirpation of the gland. The authors investigated and analyzed the retrospective charts of 236 patients who underwent surgery for oCSCC over a 10-year period and the pathology reports of 294 neck dissections with SMg removal. SMg involvement was evident in 13 cases (4%). Eight cases were due to direct invasion, which was the most common mechanism. Four cases had infiltration from a metastatic periglandular lymphadenopathy, and in 1 case, metastatic disease was confirmed. The tongue and floor of the mouth were the most frequent primary sites associated with SMg involvement. The study found no bilateral cases, and in 135 SMg specimens benign pathologies were detected. involvement of the SMg in oCSCC is not frequent. it is appropriate to preserve the gland unless the primary tumour or metastatic regional lymphadenopathy is adherent to the gland.

Retención dental por diente supernumerario - Caso Clínico

Abstract: Supernumerary teeth are additional teeth that develop in the jaws. In the upper anterior sector, when they are not erupted, they are a frequent cause of alterations of the eruption of permanent teeth. The diagnosis and treatment of these dental organs is necessary to avoid subsequent complications that could alter the dental arch. This is a clinical case of a 10-year-old girl who presented with retention of the central maxillary incisor related to a supernumerary tooth. The proposed treatment involved the surgical extraction of the supernumerary tooth, a waiting and observation approach, the surgical exposure of the retained central incisor and the orthodontic traction thereof with a removable device.
