[Deep neck infections: complications of acute pharyngitis].

: Deep neck infections develop as aftermath of spreading infections from an initial focus to the neighbourhood and soft tissues of the neck, through routes offering lesser resistance as fascial sheets. These cervical pictures are not numerous and generally after infective focus bad treated, linked with concomitant factors easing the rapid spread. The presence of complications as the involvement of great blood vessels, mediastin or jeopardizing the air-way may darken the prognosis, for which reason its precocious diagnosis and correct behaviour are very decisive. The paper deals with one case of neck infect, following an acute banal pharyngitis without predisposing circumstances. Follows a review of the published bibliography.
