[Paraganglioma of the vagus. A case report and review of literature]. / Paraganglioma del nervio vago. Presentación de un caso y revisión de la literatura.

The vagal nerve paraganglioma is a rare tumor over all the head and neck tumours. It presents with a insidious clinic, appearing usually as a asymptomatic laterocervical mass of low growth pattern. We present a case of a 53 years old woman with a left of painless laterocervical mass that produced cough with the palpation. We pretend to review the most relevant aspects of the diagnosis and treatment of the paraganglioma and therefore include this pathology in the differential diagnosis of laterocervical tumor.

[Subcutaneous autograft with newly synthesized cartilage using ethisorb polymer in rabbits]. / Autoinjerto subcutáneo de cartílago neosintetizado utilizando el polímero ethisorb en conejos.

We perform a subcutaneous autograft, in animals with preserved immunity (24 rabbits), of cartilage taken from the auricle, treated with tissue engineering thecnics and embeded in a reabsorbable polimer (Ethisorb) that acts as base. We observed a good quality cartilage with the expression of collagen type II and without graft rejection phenomenon.

[Experimental animal model for laryngeal cartilage transplantation]. / Modelo de experimentación animal en cirugía de trasplante de cartílago laríngeo.

We evaluated the rabbit (New Zealand) as an experimental animal in reconstructive laryngeal surgery. We report our experience and describe features of rabbit anatomy and surgery.

[Oropharyngeal pemphigus vulgaris]. / Penfigo vulgar orofaringeo.

Etiologic and pathogenic as well the Pemphigus vulgaris is an autoimmune disease, being its symptomatology polysystemic. Accordingly, under the diagnostic viewpoint, must be considered as a multidisciplinary illness. Either the evolutive course, the differential diagnosis or the treatment emphasizes the importance of the attendance of these patients ambulatory or hospitalized. An exclusively ENT case of pemphigus vulgaris seen by the AA. compelled them to a perusal of the bibliography of the subject, in order to update the problems of diagnosis and treatment of the disease.

[Keratosis obturans]. / Keratosis obturans.

The Keratosis obturans is a disease localized in the EAC. It is an important pathology because its physiopathology differs from other analogous diseases of the same site, and has a clinical and pathological aspect uniform and peculiar, in spite of its evolutive course. The AA. review the bibliography and report their experience with the aim to define and classify this disorder.

[Goldenhar syndrome: apropos of 2 cases]. / Síndrome de Goldenhar: a propósito de dos casos.

The arc branch syndrome are a group of diseases whose classification and etiology are unknown yet. We has 2 patients with Goldenhar's syndrome and we have studied the etiopathogenicity and treatment in these diseases.

[Surgery and radiotherapy in esthesioneuroblastoma of the nose, apropos of 2 cases]. / Cirugía y radioterapia en el estesioneuroblastoma olfatorio, a propósito de dos casos.

The esthesioneuroblastoma is a rare tumor localized in nose and sinus with difficult diagnosis (aspect like undifferentiated carcinoma and lymphosarcoma) local malignant.

The extramedullary plasmocytoma is a rare condition accounting for one per cent of malignancies of the upper air way. We present one case of rhinosinusal location, which diagnosis offered some difficulties owing to both the X-ray and clinical findings. Treated with radio- and chemotherapy (without any surgery) the result proved good. In the paper the AA. review and bring up-to-date this pathology.

[Dysphonia caused by idiopathic skeletal hyperostosis. Apropos of a case]. / Disfonía por hiperostosis esquelética idiopática. A propósito de un caso.

The Forestier's disease is an skeletal idiopathy described by this A. and Rotés Querol, in 1950, characterized by the systemic ossification in variable degree of the vertebral column. The neck localization can produce pharyngeal or laryngeal symptoms, due to the compression of the structures of the neighbourhood. So was the case recorded which being symptomless remain untreated. Survey of today's literature on the subject so as diagnosis, pathophysiology and its management.

[Mucous nasosinus melanoma. Apropos of a case]. / Melanoma mucoso nasosinusal. A propósito de un caso.
