Evolution of oral neoplasm in an andalusian population (Spain).

BACKGROUND: Head and neck cancer are one of the most common neoplasm pathologies in humans. The aim of this study was to analyze the type, characteristics, treatment and evolution of oral neoplasm or precancerous lesion in a sample of Andalusian population (Spain) derived from the Oncology Rehabilitation Hospital Unit during a period of 20 years. MATERIAL AND METHODS: A retrospective descriptive study was carried out during the years 1991 and 2011 analyzing the type, characteristics, treatment and follow-up of oral neoplasm in the Oral and Maxillofacial Surgery Unit of the Universitary Hospital Virgen del Rocio. The inclusion criteria were patients whose underlying pathology was any type of benign or malignant neoplasm or presence of precancerous lesion that, after treatment, had been referred to the Prosthetic Rehabilitation Unit. RESULTS: Of the initial analyzed sample of 60 patients, only 45 patients met the inclusion criteria. Of the final sample analyzed, 31 subjects were men (68.9%) and 14 women (31.1%) (p = 0.0169). The mean age of the sample was 57 years ± 13.83, been more frequently in older people with more than 50 years (73.3%) (p = 0.0169). The most common type of neoplasm was epidermoid carcinoma (64.4%). The site most frequently found in squamous cell carcinoma was the floor of the mouth (31%). The most frequent treatment modality was surgery with postoperative radiotherapy (42.2%). All patients had a minimum follow-up of 5 years, and a recurrence in this period was identified in 11.1% of the sample. Multivariate logistic regression showed a statistically significant association for the variables age (p = 0.0063) and smoking (p = 0.0434). CONCLUSIONS: Epidermoid carcinoma is the most frequent tumor in the oral cavity, where increase age and smoking are confirmed as associated risk factors.

Uso de obturadores en cirugía oral y maxilofacial. Presentación de cinco casos clínicos / Use of obturators in oral and maxillofacial surgery. A report of five cases

Los defectos creados en el maxilar, principalmente tras cirugía resectiva de tumores malignos, traumatismo o defectos congénitos, deben ser corregidos con el fin de recuperar los consecuentes déficits en el habla, la deglución, la masticación y la estética. Para ello contamos con dos amplias posibilidades: reconstrucción quirúrgica o colocación de un obturador protésico maxilar. En este artículo llevamos a cabo una revisión de la literatura reciente y clásica sobre obturadores palatinos, ilustrándola mediante 5 casos clínicos con esta opción terapéutica. Hemos encontrado descritas una amplia variedad de modificaciones para los distintos tipos de obturadores, como la fabricación de aletas nasales, colocación de obturadores de forma inmediata tras la cirugía, el hecho de ahuecar el aditamento obturador, etc. En nuestra práctica hemos observado una serie de ventajas en la colocación de este tipo de prótesis de forma posquirúrgica diferida y en estrecha colaboración con su médico responsable(AU)

Defects created in the maxillary bone, principally after surgical resection of malignant tumors, trauma or congenital defects, must be corrected to eliminate the resulting speech, swallowing, and chewing defects and restore the cosmetic appearance. Two major options available are surgical reconstruction or the placement of a maxillary obturator prosthesis. The recent and classic literature on palatal obturators is reviewed and five clinical cases treated with a palatal obturator are reported. A large variety of modifications have been reported for different types of obturators, such as nasal wings, immediate postoperative obturator prosthesis placement, etc. In the authors' experience, deferred postoperative obturator placement in close collaboration with the responsible doctor has advantages(AU)

Inserción de un implante simultáneo a la extracción de un canino superior incluido / Insertion of a simultaneous implant in the extraction of an upper included canine

Presentamos el caso clínico de una paciente adulta con un canino superior incluido, en la que se llevó a cabo un plan de tratamiento multidisciplinar y secuencial quirúrgico-ortodóncicoprotésico. En un primer tiempo, se instauró un tratamiento ortodóncico con el que disponer de un espacio intercalar adecuado para la posterior reposición del canino superior. En un segundo tiempo, se realizó la extracción del canino incluido junto con un tratamiento combinado de regeneración ósea e inserción inmediata de un implante, para finalizar con la restauración protésica mediante una corona implantosoportada. Se revisa además la literatura al respecto y el estado actual del problema (AU)

We present a clinical case of an adult patient with an impacted upper canine, a multidisciplinary and sequential surgical-orthodontist-prosthetic treatment plan was made. In a first time, an orthodontic treatment was established in order to have a suitable space to a later upper canine replacement. In a second instance, the extraction of the canine was done, including a combined treatment of bone regeneration, with an immediate insertion of an implant. To conclude the treatment a prosthetic restoration with a crown supported on an implant was completed. Review of the literature was done in order to present the actual situation of the problem (AU)
