[Laryngeal fibroendoscopic surgery. Our experience]. / Cirugía fibroendoscópica laríngea. Nuestra experiencia.

Since 1992, when our department acquired a flexible fiberscope with a working channel, we have used it in surgery on the upper respiratory and digestive tract. We call our technique laryngeal fiberscopic surgery. We report the results of four years of experience in this field. A total of 368 surgical interventions were performed, almost half to remove benign lesions of the vocal cords (polyps, nodules, etc). This technique is a major advance in our field of study. Its main advantages are avoidance of general anesthesia and hospitalization, reduction of surgical risk, and savings of time and money. We consider it to be a useful alternative to traditional direct laryngoscopy (Kleinsasser technique) for many applications.

Cirugía fibroendoscópica laríngea. Nuestra experiencia / Laryngeal fibroendoscopic surgery. Our experience

Desde que, en 1992, nuestro servicio adquirió unfibrolaringoscopio flexible con canal de trabajo, comenzamos a realizar con él intervenciones quirúrgicas en la vía aerodigestiva superior, desarrollando una técnica a la que hemos denominado cirugía fibroendoscópica laríngea. En el presente artículo exponemos nuestra experiencia en los últimos cuatro años en este campo. Hemos realizado un total de 368 intervenciones, de las cuales casi un 50 por ciento han sido extirpaciones de lesiones benignas de cuerda vocal (pólipos, nódulos, etc.). Creemos que supone un gran avance en el campo de nuestra especialidad, siendo sus principales aportaciones, evitar la anes-tesia general y el ingreso hospitalario, la reducción de riesgos quirúrgicos y el ahorro de gastos económicos y de tiempo. Consideramos que es una alternativa más que razonable a la clásica laringoscopia directa en suspensión (técnica de Kleinsasser) en muchas de sus indicaciones (AU)

[Laryngeal sarcomatoid carcinoma: clinical, histological and immunohistochemical study of four cases]. / Carcinoma sarcomatoide de laringe: estudio clínico, histológico e inmunohistoquímico de cuatro casos.

The purpose of this study was to confirm how the use of immunohistochemical techniques can help to differentiate between tumors with a mixed proliferative pattern (epithelial and mesenchymal). It is fundamental to differentiating tumors of these characteristics in order to determine the prognosis and plan treatment. We used different techniques on tissue samples from four cases diagnosed as laryngeal sarcomatoid carcinoma. The results demonstrated that all four were sarcomatoid carcinomas, which correlated with the patients' favorable clinical evolution. The immunohistochemical study was useful for differentiating tumor type in the case of a biopsy specimen obtained from a mixed-pattern neoplasm.

[Nasopharyngeal melanoma: a case report]. / Melanoma de nasofaringe. A propósito de un caso.

The AA. present a case of disseminated primitive melanoma of the rhinopharynx. The main difficulty was to establish the differential diagnosis, owing to the rarity of this tumor's type in such a sitting. The patient showed intracranial metastases which took him to death in a short term.
