ABSTRACT
Presentamos un caso clínico donde, utilizando implantes subperiósticos o supraóseos, es decir, estructuras metálicas tridimensionales personalizadas de titanio fabricadas de forma digital, hemos conseguido realizar dos objetivos a la vez: 1) la corrección de una severa deformidad facial, y 2) dotar a la paciente de fijaciones o implantes para la rehabilitación implantosoportada de su edentulismo maxilar completo. No tenemos constancia de ningún caso similar publicado en la literatura a día de hoy.Creemos que esta nueva técnica, relativamente sencilla, puede ser una alternativa a las cirugías complejas que involucran el empleo de complicados injertos óseos, con el consiguiente ahorro en tiempo y morbilidad para los pacientes que asocian hipoplasia maxilar y edentulismo con grave atrofia ósea.

We present a clinical case in which, using subperiosteal or supraosseous implants, that is to say, three-dimensional personalized metallic titanium structures manufactured digitally, we have managed to achieve two objectives at the same time: 1) correction of a severe facial deformity, and 2) furnish the patient with fixations or implants for the implant-supported rehabilitation of her complete maxillary edentulism. We are not aware of any similar case published in the literature to date.We believe that this new, relatively simple technique can be an alternative to complex surgeries that involve the use of complicated bone grafts, with the consequent savings in time and morbidity for patients who associate maxillary hypoplasia and edentulism with severe bone atrophy.

INTRODUCTION: The effect of the wide long-wave CO2 laser is the thermal vaporization of the tissues, getting a maximum energy concentration with a minimum of tissue penetration. In oral surgery, it is generally used for the treatment of oral and oropharyngeal small mucous tumors, due to the scarce morbidity that takes place and the absence of reconstructive necessity. OBJECTIVE: To analyze the postoperative evolution, in the patients treated by oral and oropharyngeal epidermoid carcinomas, after CO2 laser resection. To compare it with that of the patients treated by means of conventional surgical methods, achieving the reconstruction through direct suture or the employment of local, regional or distance flaps. METHODS: A prospective study was designed including 70 patients treated by oral and oropharyngeal epidermoid carcinomas. Thirty-five patients were treated by means of CO2 laser, in 10 cases direct wound-closure was realized, and in the remaining 25 patients some local, regional or distance flap were used. There were analysed the presence of postoperative pain, the degree of cicatricial retraction, and the speech and swallowing functional results. RESULTS: We obtained a smaller painful degree and postoperative cicatricial retraction by the employment of CO2 laser. It permits minimizing the functional speech sequels (better words articulation) and swallowing (effective and precocious functional recovery). CONCLUSION: CO2 laser resection has become the elective treatment for small oral and oropharyngeal epidermoid carcinomas. The reasons are the absence of reconstructive surgery necessity, the scarce cicatricial retraction, and the excellent postoperative evolution.

BACKGROUND: Heterotopic islands of salivary tissue are commonly found in the intraparotid lymph nodes and, less commonly, within extraparotid cervical nodes. Salivary gland tumors, both benign and malignant, can develop within this ectopic salivary tissue. CASES: Two patients presented with a solitary, painless mass in the cervical region. Fine needle aspiration cytology was performed, and the smears revealed a mixture of intermediate and mucus-secreting cells associated with extracellular mucin. The tumors were removed, and the diagnosis of mucoepidermoid carcinoma was confirmed by histologic study. CONCLUSION: The finding of a malignant cervical salivary gland tumor does not necessarily represent a metastasis from an occult site.

El carcinoma fusocelular es una variedad del carcinoma de células escamosas, de infrecuente presentación e histogénesis controvertida. Aunque puede afectar a cualquier parte de la economía, se localiza más frecuentemente en las vías aerodigestivas superiores. La mayoría de los ubicados en la cavidad oral son invasores y tienen mal pronóstico.Presentamos un caso de carcinoma de células fusiformes que afectaba al espacio masticador, encontrándose la mucosa supraadyacente libre de neoplasia. Hacemos especial hincapié en la metodología histológica e inmunohistoquímica (positividad para las citoqueratinas de bajo peso molecular y, con menor intensidad, para las citoqueratinas de alto peso molecular y la vimentina) empleada para su diagnóstico, así como una valoración de los factores pronósticos y las posibilidades terapéuticas que ofrece esta infrecuente neoplasia (AU)
