Perforación faríngea durante procedimiento endoscópico terapéutico. Informe de caso

A clinical case of a failed endoscopic therapeutic procedure presenting subcutaneous emphysema, suggestive of a perforation is discussed. In order to define the topography and to make a differential diagnosis of the lesion, a clinical signs sequence is conducted that revealed a perforation of the posterior pharynx, then confirmed using endoscopic imaging. An algorithm is suggested to make the differential diagnosis between an intra and an extra-glottic perforation.
