Metástasis de carcinoma escamoso de laringe en seno cavernoso.

The spread to the cavernous sinus in laryngeal cancer means the presence of a disseminated disease and short survival. The aim of this paper is to report a case of laryngeal squamous carcinoma of the larynx. A search was conducted in the databases of Medline and SciELO DOYMA using the words "cavernous sinus metastasis”. We found 10 published cases of laryngeal squamous carcinoma with metastasis to the cavernous sinus.  The average survival of the 10 cases reported in the literature was 4.1 months; in our case it was 9 months. Patients who received radiotherapy improved symptomatically. In some cases the diagnosis was confirmed only after necropsy. In this type of lesions, surgery is used for diagnosis rather than as a therapeutic tool.
