Introduction: The combination of non-vascularized iliac crest bone graft and distraction osteogenesis in a second surgical intervention has only been described to achieve alveolar ridge augmentation. This technique is not recommended to treat bone defects of the jaws caused by firearm projectile. Case presentation: 40-year-old woman with a segmental mandibular defect in the mandible body caused by the impact of a firearm projectile at the age of 1 year. The patient developed a severe Class II dentofacial anomaly that required a two-stage treatment; she underwent mandibular reconstruction with free iliac crest bone graft followed by a bilateral mandibular distraction at the level of the iliac crest bone graft. With these interventions, a remarkable improvement of the patient's malformation was achieved. Conclusion: Horizontal distraction of the free iliac crest bone graft is a safe and predictable procedure to treat dentolabial anomalies requiring mandibular reconstruction. This procedure was performed in the patient without complications. Further studies on the effectiveness of this technique are required. RESUMEN Introducción. La combinación del injerto de la cresta ilíaca no vascularizado y la distracción osteogénica del injerto en una segunda intervención quirúrgica solo ha sido descrita para lograr un aumento del reborde alveolar. Esta técnica no se recomienda para tratar defectos óseos en la mandíbula causados por proyectil de arma de fuego. Presentación del caso. Mujer de 40 años con un defecto mandibular segmentario en el cuerpo mandibular causado por el impacto de un proyectil de arma de fuego a la edad de 1 año. La paciente desarrolló una anomalía dentofacial grave Clase II que requirió dos tratamientos en diferentes momentos: en primer lugar, se le practicó una reconstrucción mandibular con injerto de cresta ilíaca libre y posteriormente, una distracción mandibular bilateral que incluyó un injerto libre de cresta ilíaca. Con estas intervenciones se logró una mejoría notable de la malformación de la paciente. Conclusión. La distracción horizontal del injerto de cresta ilíaca libre es un procedimiento seguro y predecible para tratar anomalías dentolabiales que requieran reconstrucción de la mandíbula; no obstante, es necesario realizar más estudios sobre la efectividad de la técnica frente este tipo de malformaciones.

Introducción: Los desarreglos internos de la Articulación Temporomandibular son los más comunes. La artroscopia es de gran utilidad en Cirugía Maxilofacial como alternativa para el diagnóstico y tratamiento de los desarreglos internos de la Articulación Temporomandibular. Objetivo: El objetivo de la presente revisión es describir la artroscopia diagnóstica de la Articulación Temporomandibular. Me?todos: Se realizó una revisión narrativa de la literatura y búsqueda en las bases de datos Pubmed, Proquest, Scielo, Mendeley y Elsevier, en idioma ingle?s y espan?ol empleando los descriptores (Artroscopia diagnóstica, Articulacion Temporomandibular) en español e ingles. Se seleccionaron arti?culos publicados en un periodo de 40 an?os (1980-2020), incluyendo en el estudio un total de 26 arti?culos y 6 libros de 702 documentos revisados. Discusión: En la artroscopia de la Articulación Temporomandibular se puede observar la posición, calidad, textura del cartílago articular, la vascularización y la redundancia de la membrana sinovial, y se pude realizar procedimientos como técnicas de artroscopia avanzada. Conclusiones: La artroscopia diagnóstica facilita el diagnóstico y manejo de las patologías intraarticulares. Siendo necesario e imprescindible el conocimiento de esta técnica.

Roberts Syndrome is an extremely rare syndrome reporting about 150 cases in the literature, with a very low survival rate. The authors present a case of a female patient with Roberts Syndrome who also had a coronal craniosynostosis. The aim of this case report is to present a case of a patient with Roberts Syndrome with a brachycephaly that required management of fronto-orbital advancement. In conclusion Roberts Syndrome is a rare disease, which can have different skeletal variations. This syndrome can manifest itself with craniosynostosis, with the requirement of a comprehensive management to correct it and avoid compression of the brain with endocranial hypertension.

Isolated zygomatic arch fractures are common fractures in maxillofacial trauma. These fractures can trigger a functional alteration in the mouth opening and closing. Until now, there is no published classification of an isolated zygomatic arch fracture that contains the presence or not of coronoid impingement. So we propose a new classification that is easy to handle and has the largest number of scenarios that can occur in this type of fracture. The isolated zygomatic arch fracture is classified as Type I: Nondisplaced fractures, Type II: Greenstick fracture with or without coronoid impingement, Type III: Single displaced fracture with or without coronoid impingement, Type IV: Multiple displaced fracture with or without coronoid impingement, Type V: Comminuted fracture with or without coronoid impingement. We consider it to be a comprehensive classification, with general concepts of bone fractures, that can be incorporated into professional daily practice.

Purpose At the current time, there is lack of uniformity in the management of major salivary gland tumors because of the existence of many subtypes. The aim of this study, performed at the National Cancer Institute from January 2014 to January 2019, was to characterize the tumor pathologies of the parotid gland. Methods A retrospective descriptive observational study was conducted with the clinical records of patients admitted for parotid gland pathologies at the National Cancer Institute, from January 2014 to January 2019. The entire cohert, including those who met the inclusion criteria and those that met the exclusion criteria, was studied (N = 101). Descriptive association measures, such as the χ2 test, were used. Results A higher frequency was found among males (61.4%; n = 62), with a male-to-female ratio of 1.5:1 and a significant statistical difference (P Conclusions Primary malignant tumors of the parotid glands were rare in our series, with metastasis being the main cause of parotidectomy; squamous cell carcinoma predominantly originated in the skin. The male gender was the most affected.
