RESUMEN
OBJECTIVES: Describe the techniques involved and the results obtained witn nasolabial flaps in small and medium-sized defects of the oral cavity. The procedure is an easy resconstructive option with a high success rate and with very good aesthetic and functional outcomes. STUDY DESIGN: A retrospective analysis of 16 nasolabial flap reconstructions in 15 oncological patients with oral cavity defects undergoing single-stage surgical interventions. We evaluate the tumor type, its location, size, the resective and reconstructive techniques involved, as well as any complications. RESULTS: Out of 15 patients, 9 were male and 6 female, with ages ranging from 60-85 years. The primary tumor was located in the mandibular or maxillary gingiva in 7 patients, the lateral margin of the tongue in 5, the floor of the mouth in 3 and the mandibular symphysis in a single patient. The tumors were of a small to medium size. All patients underwent intraoral resections. In most cases, a cervical dissection was performed. All flaps were completed as single-stage surgical interventions, with 14 unilateral and 2 bilateral procedures. Five patients had received radiotherapy treatment for previous tumors. During the follow up period, which ranged from 4 months to 8 years, only one patient required their flap to be thinned, there were two incidents of surgical wound dehiscence, two hematomas and one orocutaneous fistula, none of which affected the survival of the flap. CONCLUSIONS: The nasolabial flap proves highly versatile in oral cavity reconstructions, coupled with a minimal morbidity of the donor region and good aesthetic and functional results. Its high vascularity allows for cervical dissections to be carried out or even for radiotherapy to be administered prior to it. It is straightforward, safe, and carrying it out as a single-stage intervention makes it the ideal surgical option for small to medium intraoral defects in edentulous patients with other comorbidities.

Background: Oral cancer is the 11th most common type of cancer in the world, with established major risk factors as tobacco and alcohol, and recently included high-risk human papillomavirus types 16 and 18. HPV types 16 and 18 are the etiologic agents of cervical cancers and a proportion of oropharyngeal cancers. However, the picture of HPV and the clinical implications of oral cancers are not clear with most reports combining oral cancer data with head and neck cancers. It has been confirmed as a favorable prognostic factor in oropharyngeal cancer. However, the prognostic value of HPV in oral squamous cell carcinoma is still unclear. Material and Methods: The main objective of this article is to present the evidence encountered following a bibliographical review of recent publications specifically related to oral cancer and its differences from oropharyngeal cancer. The secondary goals are to present the findings of a five-year retrospective observational study of the prevalence of HPV infection in oral cancer patients treated by the Oral and Maxillofacial Surgery Department at La Paz University Hospital (Madrid, Spain), and finally, we to evaluate and compare our country's HPV prevention program in comparison to other European countries. Results: According to the review of the literature, HPV positive oral squamous cell carcinoma is associated with significantly decreased overall survival and distant control. Bibliographic review suggest HPV infection can be used as a negative prognostic factor in oral squamous cell carcinoma. Conclusions: As regards diagnostic testing for HPV, it should be extended to as many cases of oral cavity squamous cell carcinoma as possible, especially in those with risk factors. The current vaccination program in Spain does not have adequate coverage and is significantly under the level of other European Union countries; it should be expanded and catch-up strategies should be included. Key words:HPV, OSSC, Papillomavirus, oral carcinoma, prevention.
RESUMEN
El brote epidémico causado por el virus SARS-CoV-2 se encuentra plenamente activo en España. Alrededor del 10-15 % de los pacientes ingresados precisan cuidados en unidades de críticos, siendo intubados de forma prolongada y precisando la realización de traqueotomías. Se realiza un estudio observacional de las traqueotomías realizadas por nuestro Servicio de Cirugía Oral y Maxilofacial a pacientes COVID-19 de unidades de cuidados intensivos realizadas entre el 17 de marzo y el 17 de abril de 2020. El estudio analiza aspectos epidemiológicos y clínicos de los pacientes, el tipo de técnica quirúrgica empleada, el tiempo quirúrgico, el tipo de cánula empleada, las complicaciones postquirúrgicas y el seguimiento clínico de los pacientes. Un total de 22 pacientes fueron sometidos a traquetomía reglada abierta. Fueron dieciocho hombres y cuatro mujeres de edades entre 40 y 77 años (64,9 años de media). En todos los casos la realización de traqueotomía fue como consecuencia del proceso pulmonar por la neumonia bilateral COVID-19. Dos pacientes presentaron un neumotórax en el postoperatorio inmediato como complicación, un paciente falleció durante la realización del procedimiento y otro tras su llegada a la Unidad de Cuidados Intensivos tras la realización de la traqueotomía. A pesar de que la traqueotomía es una técnica quirúrgica reglada, las características especiales de los pacientes COVID-19 hacen de este procedimiento una situación crítica por la inestabilidad pulmonar y la rápida desaturación del paciente. Todo ello obliga a la realización del procedimiento por facultativos con experiencia para disminuir el tiempo quirúrgico y poder enfrentarse a cualquier eventualidad
The outbreak caused by the SARS-CoV-2 virus is currently very active in Spain. Many infected people still require to be hospitalized. Around 10-15 % of hospitalized patients require intensive care, where they are intubated for a prolonged period, needing tracheotomies some weeks after the intubation. We will be conducting an observational study of the tracheotomies performed by our oral and maxillofacial Department to COVID-19 patients on intensive care units between March 17th and April 17th, 2020. This study will be analyzing the patients' epidemiological and clinical aspects, surgical technique employed, surgical time, type of cannula used, postoperative complications and the patients' clinical monitoring. A total of 22 patients underwent open elective tracheotomy. There were twenty-two males and three females aged between 40 and 77 (mean: 64,9 years-old). In all cases tracheotomy was carried out due to pulmonary process caused by COVID-19 bilateral pneumonia. Two patients presented pneumothorax in the immediate postoperatory care as a complication, one perished during the procedure and another did so after arriving to the Intensive Care Unit after the tracheotomy surgery. Even though tracheotomy is a ruled surgical technique, the special characteristics of COVID-19 patients make of this procedure a critical situation, mainly due to lung instability and quick desaturation of the patients. This requires the surgery to be carried out by experienced physicians in order to reduce operative time and to be able to react to any eventualities that may arise

BACKGROUND: Adverse outcomes resulting from aspiration or ingestion of instruments and materials can occur in any dental procedure. Clinical manifestation depends on the location, the obstructive potential of the foreign body, and the temporal factor since the accidental incident. Accidental inhalation of dental appliances can be an even more serious event than ingestion and must always be treated as an emergency situation. CASE REPORT: A 62-year-old woman was admitted to our hospital with the suspicion of ingestion of a screwdriver implants. In spite of the clinically asymptomatic presentation, chest radiography in posteroanterior and lateral projections showed a radiopaque dental instrument impacted on the right main inferior bronchus. Rigid bronchoscope was successful to remove the dental instrument under general anesthesia, and the patient was discharged 24 h later. CONCLUSION: Aspiration and ingestion of dental foreign objects are infrequent, but they can occur at large multidisciplinary dental procedures. These episodes have the potential to result in acute medical and life-threatening emergencies since the beginning of the event or at a late stage in proceeding in the underdiagnosed patient. Prevention of such incidents is, therefore, the best approach via the mandatory use of precautions during all dental procedures, and in case of suspicion with no retrievable material, patient must always be submitted to a radiographic study.

Los schwannomas del nervio facial intraparotídeos son tumores benignos poco frecuentes, suponiendo frecuentemente un reto diagnóstico y terapéutico. La mayoría de los pacientes presentan una masa parotídea asintomática y las pruebas de imagen y la punción con aguja fina no suelen ser concluyentes en el diagnóstico. Tras la revisión de la literatura a propósito de un caso, pretendemos proporcionar cierta guía para el tratamiento de esta rara patología (AU)
Intraparotid schwannomas of the facial nerve are uncommon benign tumors that present a challenge in diagnosis and management. An asymptomatic parotid mass is the main clinical presentation, and image studies and fine-needle aspiration biopsy do not usually give a conclusive diagnosis. The main purpose of this study of a case report and a literature review is to provide some surgical guidance for the treatment of this rare pathology (AU)

Objetivo: Presentamos una revisión de 160 submaxilectomías realizadas en el Hospital La Paz de Madrid durante 10 años. Material y métodos: Se revisan retrospectivamente todas las historias clínicas de los pacientes intervenidos de submaxilectomía desde enero de 2001 hasta julio de 2011. En los datos se incluyen sexo, edad, anatomía patológica, pruebas diagnósticas, procedimientos quirúrgicos y seguimiento. Comparamos nuestro estudio con otros similares publicados en otros países. Resultados: En nuestra serie la sialoadenitis crónica y la sialolitiasis de la glándula submaxilar representan 114 casos (71,25%). Hay 36 casos de neoplasias (78,88% benignas y 22,22% malignas). El tumor benigno más frecuente es el adenoma pleomorfo (26 casos) y el tumormaligno más frecuente es el carcinoma adenoide quístico (7 casos). Conclusiones: En nuestro centro la causa más frecuente de submaxilectomía la constituyen la sialoadenitis crónica y la sialolitiasis. Las neoplasias más frecuentes son el adenoma pleomorfo y el carcinoma adenoide quístico, en consonancia con diferentes estudios de otros países. Los tumores benignos son más frecuentes, en contraste con otros estudios previos (AU)
Objective: A review is presented of 160 sub-mandibular gland excisions performed at third level hospital over a ten year period. Patients and methods: The medical records and case notes of all patients with submandibular gland excision were reviewed retrospectively from January 2001 to July 2011. This data included gender, age, histopathology of the submandibular gland, diagnostic procedures, surgical reports, and follow-up. This study was also compared with similar studies published in other countries Results: Chronic sialadenitis and sialolithiasis of the submandibular gland was found in 114 cases (71.25%) of the series. Thirty-six neoplasms (78.88% benign and 22.22% malignant) were found. The most frequent benign and malignant neoplasms found were pleomorphic adenoma (26 cases) and adenoid cystic carcinoma (7 cases), respectively. Conclusions: The present study showed that the main cause of sub-mandibular gland excision in our reference population was sialadenitis and sialolithiasis. The most frequent neoplasms were pleomorphic adenoma and adenoid cystic carcinoma, similar to other published reports. In this study, there was a higher incidence of benign neoplasms than in previous reports. The most common complication was facial nerve neuropraxia (AU)

Objetivo. Conocer el protocolo de terapia anticoagulante que siguen en el perioperatorio de este tipo de intervención los principales servicios de Cirugía Oral y Maxilofacial de España que realizan microcirugía reconstructiva de cabeza y cuello. A partir de aquí, resumir la terapia anticoagulante mayoritaria e intentar unificar criterios. Material y métodos. Los autores realizan un estudio descriptivo tras contactar a través de encuesta telefónica y/o por correo electrónico con los principales servicios de Cirugía Oral y Maxilofacial de los hospitales en España en los que se realiza cirugía reconstructiva con injertos libres microvascularizados. Resultados. De los 65 servicios de Cirugía Oral y Maxilofacial de España, 29 (44%) son los integrantes del estudio. El resto de servicios se excluyen por no realizar regularmente reconstrucción microquirúrgica o no notificar los resultados de la encuesta. De estos 29 servicios participantes, 22 (73%) siguen un protocolo de antitrombosis en los procedimientos microquirúrgicos. Conclusión. Pese a no existir una pauta estandarizada de antitrombosis, hay datos concluyentes de que el dextrano no debe utilizarse por el alto riesgo de complicaciones sistémicas, así como de que los únicos fármacos que han conseguido una reducción de la trombosis microvascular son la heparina y el AAS con respecto a la ausencia de terapia antitrombótica(AU)
Objective. To find out the protocol for anticoagulation therapy in the perioperative period following microvascular reconstruction in major Oral and Maxillofacial Surgery Departments in Spain. From this, to summarise the majority anticoagulant therapy and attempt to unify criteria. Material and Methods. The authors conducted a descriptive study. A survey was performed contacting by telephone and/or email with the major Oral and Maxillofacial Surgery departments in Spain who perform reconstructive surgery with microvascular free flaps. Results. Of the 65 services of Oral and Maxillofacial Surgery Departments in Spain, 29 (44%) participated in the study. The other services were excluded owing to not practicing microsurgical reconstruction or not providing the results of the questionnaire. Of these 29 participating departments, 22 (73%) followed an antithrombotic protocol in microsurgical procedures. Conclusion. Despite the lack of a standardised antithrombotic pattern there is evidence that dextran should not be used due to the high risk of systemic complications, and heparin and aspirin are the only drugs that have achieved a reduction in microvascular thrombosis compared to the absence of antithrombotic therapy(AU)
