[Hypoglossal nerve paralysis after intubation and direct laryngoscopy]. / Parálisis del nervio hipogloso postintubación y laringoscopia directa.

We described an extremely uncommon case of hypoglossal nerve paralysis occurred after a direct laryngoscopy under general anesthesia with McIntosh's laryngoscope intubation. We reviewed the literature on similar cases and studied the etiology and pathogenesis of these paralyses.

[Dural arteriovenous fistula of the lateral sinus: origin of objective tinnitus]. / Fístula arteriovenosa dural del seno lateral: origen de acúfenos objetivos.

Objective tinnitus usually has a vascular origin, but dural arteriovenous fistulas are rarely the cause of this sign. We report a case of arteriovenous meningeal fistula (AVMF) of the lateral sinus, origin of pulsatile objective tinnitus. Etiology, pathophysiology, symptoms, diagnosis, differential diagnosis and treatment of these fistulas are reviewed.

[Distress of the airway due to vertebral ankylosing hyperostosis or Forestier-Rotes' disease]. / Compromiso de la vía aérea en la hiperostosis anquilosante vertebral o enfermedad de Forestier-Rotes.

The AA. present one case in which the air-way was severely compromised because of the causative vertebral ankylosing hyperostosis, the so-called Forestier-Rotés's malady. Only 7 of resembling cases are recorded in the consulted literature. Survey of the related bibliography and comments about pathogenic criteria and diagnostic and therapeutic questions as well.

[Adenocarcinoma of the nasal cavities and paranasal sinuses. On low-grade adenocarcinoma]. / Adenocarcinoma de fosas nasales y senos paranasales. A propósito de un adenocarcinoma de "bajo grado".

The AA. having had the opportunity to diagnose and treat one of those cases, of low degree, sitting in the nasal cavity, discuss about its classification either in the nose or in the sinuses. Their opinion is coincidental with that of other reporters regarding to the complexity and varieties of a grouping system. They propose an other one, not original at all, but having perhaps the advantage that could make easier the comprehension and the clinical orientation when dealing with these growths.

[Cervical cystic metastasis: differential diagnosis with branchiogenic carcinoma]. / Metástasis quística cervical: diagnóstico diferencial con el carcinoma branquiógeno.

This paper try to call you attention about the cystic metastatic lesion and the differential diagnostic with the branchiogenic carcinoma. We presented a case of cystic metastases in the neck, and this case has prompted us to discuss the clinic features of these metastases.
